1 00:00:04,400 --> 00:00:07,800 Speaker 1: Welcome to tech Stuff, a production from I Heart Radio. 2 00:00:12,160 --> 00:00:15,200 Speaker 1: Hey there, and welcome to tech Stuff. I'm your host, 3 00:00:15,360 --> 00:00:18,360 Speaker 1: Jonathan Strickland. I'm an executive producer with I Heart Radio 4 00:00:18,480 --> 00:00:21,040 Speaker 1: and I love all things techno. And we are back 5 00:00:21,480 --> 00:00:26,480 Speaker 1: with our series about home theaters after a brief intermission. 6 00:00:26,640 --> 00:00:30,960 Speaker 1: But hey, that happens sometimes with theaters, right anyway, So far, 7 00:00:31,120 --> 00:00:34,239 Speaker 1: we have covered the basics of visuals with a breakdown 8 00:00:34,280 --> 00:00:39,880 Speaker 1: of stuff like resolution, high dynamic range or HDR, oh 9 00:00:39,960 --> 00:00:43,839 Speaker 1: LED versus l e D versus q LED, home projectors, 10 00:00:43,880 --> 00:00:47,000 Speaker 1: and more. We also talked about surround sound and the 11 00:00:47,000 --> 00:00:50,120 Speaker 1: basic variations that you can have with surround sound. But 12 00:00:50,159 --> 00:00:51,879 Speaker 1: then I ran out of time before I could get 13 00:00:51,880 --> 00:00:54,760 Speaker 1: to the next bit, which is sub waffers. And I 14 00:00:54,840 --> 00:00:57,320 Speaker 1: talked about them a little in the last episode in 15 00:00:57,320 --> 00:00:59,600 Speaker 1: this series, but I didn't really explain what it is 16 00:00:59,680 --> 00:01:03,360 Speaker 1: they do and why they're so important for home theater setups. 17 00:01:03,720 --> 00:01:08,640 Speaker 1: All right, let's talk about subwhiffers really quickly. Now, the 18 00:01:08,760 --> 00:01:12,120 Speaker 1: job of any speaker is to project out a certain 19 00:01:12,280 --> 00:01:16,760 Speaker 1: band of sound frequencies, which we you know, experience as 20 00:01:16,760 --> 00:01:20,559 Speaker 1: different pitches. Right. Higher frequencies are higher pitches. Lower frequencies 21 00:01:20,600 --> 00:01:24,800 Speaker 1: are much lower pitches. But how do speakers do this? Well, 22 00:01:24,840 --> 00:01:27,960 Speaker 1: if you remember our rabbit hole of what sound is 23 00:01:28,240 --> 00:01:31,759 Speaker 1: from earlier in this series, you know that sound is vibration, 24 00:01:32,040 --> 00:01:34,560 Speaker 1: and that typically we hear sound as it moves through 25 00:01:34,600 --> 00:01:37,720 Speaker 1: the air. The vibration in this case becomes a series 26 00:01:37,720 --> 00:01:41,920 Speaker 1: of fluctuating changes in air pressure which propagate outward from 27 00:01:41,959 --> 00:01:45,160 Speaker 1: the source of the sound. And when these fluctuations encounter 28 00:01:45,400 --> 00:01:48,280 Speaker 1: the ear drums inside our ears, they cause our ear 29 00:01:48,360 --> 00:01:52,720 Speaker 1: drums to vibrate. Those vibrations transferred to our inner ear 30 00:01:53,120 --> 00:01:57,360 Speaker 1: thanks to some very tiny bones, and then through a 31 00:01:57,400 --> 00:01:58,960 Speaker 1: couple of other steps that I'm not going to go 32 00:01:59,120 --> 00:02:02,880 Speaker 1: to hear because I've covered this before, our brains eventually 33 00:02:02,920 --> 00:02:05,840 Speaker 1: pick up signals from our inner ear and then interpret 34 00:02:05,920 --> 00:02:10,040 Speaker 1: that as sound. Now, the reason I even said any 35 00:02:10,120 --> 00:02:13,120 Speaker 1: of that is that a speaker creates sound kind of 36 00:02:13,160 --> 00:02:17,160 Speaker 1: in a reverse process from how our ears pick up sound. 37 00:02:17,600 --> 00:02:20,520 Speaker 1: So you've got an electric signal, and this is the 38 00:02:20,560 --> 00:02:24,720 Speaker 1: signal that carries the sound information in it. We've encoded 39 00:02:24,840 --> 00:02:28,240 Speaker 1: sound into an electric signal, and then we're gonna decode 40 00:02:28,320 --> 00:02:32,880 Speaker 1: the electric signal to recreate the sound. Typically, this signal 41 00:02:32,919 --> 00:02:36,120 Speaker 1: goes to an electro magnet, which is essentially a driver 42 00:02:36,440 --> 00:02:40,280 Speaker 1: that can pull and push depending on how or if 43 00:02:40,360 --> 00:02:44,079 Speaker 1: current is flowing through the electro magnet. This is inside 44 00:02:44,120 --> 00:02:47,760 Speaker 1: the speaker. It's usually attached to the speaker cone itself, 45 00:02:48,200 --> 00:02:52,240 Speaker 1: and there is a diaphragm covering the speaker cone the 46 00:02:52,400 --> 00:02:54,720 Speaker 1: end of the cone. This is the part that you 47 00:02:54,760 --> 00:02:56,360 Speaker 1: see when you look at the front of a speaker, 48 00:02:56,600 --> 00:02:59,640 Speaker 1: those big round things. That's the diaphragm on the end 49 00:02:59,680 --> 00:03:05,239 Speaker 1: of the own um. Then you've got this part of 50 00:03:05,280 --> 00:03:07,640 Speaker 1: the back of the speaker where there's a permanent magnet. 51 00:03:07,840 --> 00:03:10,520 Speaker 1: That's your typical way. You could have it the other way, 52 00:03:10,560 --> 00:03:12,800 Speaker 1: where the permanent magnet is on the cone and the 53 00:03:12,800 --> 00:03:15,160 Speaker 1: electro magnets in the back of the speaker. But more 54 00:03:15,200 --> 00:03:19,040 Speaker 1: frequently the voice coil as it's called, is attached to 55 00:03:19,080 --> 00:03:22,360 Speaker 1: the code itself. So when the polarity of the electro 56 00:03:22,440 --> 00:03:27,120 Speaker 1: magnet changes, it exerts a magnetic force that then interacts 57 00:03:27,160 --> 00:03:31,000 Speaker 1: with the magnetic field of the permanent magnet. So if 58 00:03:31,040 --> 00:03:36,800 Speaker 1: those polarities match right, if the electro magnets magnetic field 59 00:03:36,800 --> 00:03:40,680 Speaker 1: has a north pole pointed toward the permanent magnets north pole, 60 00:03:41,240 --> 00:03:46,200 Speaker 1: then they repel each other right, Because like magnetic charge repels, 61 00:03:47,160 --> 00:03:49,800 Speaker 1: So the cone gets pushed away from the permanent magnet 62 00:03:50,080 --> 00:03:53,680 Speaker 1: and it's pushed forward out from the speaker. If the 63 00:03:53,720 --> 00:03:56,800 Speaker 1: polarities are the opposite of each other, like one's north 64 00:03:56,800 --> 00:03:59,680 Speaker 1: pole and one south pole, the electro magnet is pulled 65 00:03:59,720 --> 00:04:03,640 Speaker 1: back toward the permanent magnet inside. Now the permanent magnet, 66 00:04:03,680 --> 00:04:06,600 Speaker 1: it's magnetic field is not going to change because it's permanent. 67 00:04:06,720 --> 00:04:12,400 Speaker 1: It's it's in a stationary position. But by reversing the 68 00:04:12,400 --> 00:04:15,600 Speaker 1: the flow of electricity through the coil, you can change 69 00:04:15,640 --> 00:04:18,560 Speaker 1: the direction of the magnetic field on the coil in 70 00:04:18,600 --> 00:04:22,359 Speaker 1: the electro magnet and thus have this interaction. So the 71 00:04:22,440 --> 00:04:25,880 Speaker 1: result is that the speaker's diaphragm gets moved in and out, 72 00:04:25,920 --> 00:04:31,640 Speaker 1: and this happens really really fast. Now, the diaphragm consequently 73 00:04:31,960 --> 00:04:35,200 Speaker 1: causes air to move, and it creates those fluctuations in 74 00:04:35,279 --> 00:04:38,880 Speaker 1: air pressure. As the diaphragm pushes outward, it compresses the 75 00:04:38,920 --> 00:04:42,160 Speaker 1: air directly in front of the speaker. If it moves inward, 76 00:04:42,279 --> 00:04:44,520 Speaker 1: it pulls on the air. So you get these little 77 00:04:44,560 --> 00:04:47,800 Speaker 1: fluctuations of air pressure that when they encounter our ears 78 00:04:47,839 --> 00:04:52,160 Speaker 1: we experience as sound. To me, is so cool that 79 00:04:52,240 --> 00:04:56,200 Speaker 1: we can take sound. We can transmit sound through a microphone, 80 00:04:56,200 --> 00:04:58,320 Speaker 1: which is, by the way, the exact same thing but 81 00:04:58,400 --> 00:05:01,680 Speaker 1: in reverse, and in be able to play it out 82 00:05:01,720 --> 00:05:05,360 Speaker 1: on a speaker this way and just have this material, 83 00:05:05,520 --> 00:05:08,640 Speaker 1: this diaphragm material. Just through that vibration, we can recreate 84 00:05:08,960 --> 00:05:12,279 Speaker 1: any sound that humans can hear. That still blows my 85 00:05:12,360 --> 00:05:15,279 Speaker 1: mind anyway. That's a really high level way of how 86 00:05:15,440 --> 00:05:20,840 Speaker 1: speakers work. So most speakers can replicate a fairly decent 87 00:05:21,000 --> 00:05:24,800 Speaker 1: range of frequencies, but the lower end stuff gets pretty 88 00:05:24,880 --> 00:05:28,760 Speaker 1: challenging because it requires a larger diaphragm in the speaker 89 00:05:28,800 --> 00:05:34,760 Speaker 1: to produce good, powerful low frequency effects and more power 90 00:05:34,800 --> 00:05:38,320 Speaker 1: to move that big diaphragm. So larger diaphragms will have 91 00:05:38,400 --> 00:05:40,920 Speaker 1: more mass. That means it takes more energy to get 92 00:05:40,960 --> 00:05:44,080 Speaker 1: them to move, particularly to move enough air to make 93 00:05:44,120 --> 00:05:46,280 Speaker 1: the effects you want to make. So it might need 94 00:05:46,360 --> 00:05:50,160 Speaker 1: so much energy that you could even require an extra 95 00:05:50,240 --> 00:05:53,920 Speaker 1: plug to plug the speaker into, say an external source 96 00:05:53,960 --> 00:05:56,719 Speaker 1: like a like a power outlet. In order to get 97 00:05:56,839 --> 00:06:00,320 Speaker 1: the power, you need to to actually run the sub offer. 98 00:06:01,120 --> 00:06:04,800 Speaker 1: So a good sound system needs a subworffer that is 99 00:06:04,880 --> 00:06:08,520 Speaker 1: specifically a type of speaker specifically dedicated to replicating the 100 00:06:08,600 --> 00:06:13,000 Speaker 1: lower frequency sounds, those really deep bass sounds that sometimes 101 00:06:13,040 --> 00:06:16,560 Speaker 1: you can actually feel more than you can hear. Now, 102 00:06:16,600 --> 00:06:19,039 Speaker 1: remember I said that sound is a vibration. Well, a 103 00:06:19,040 --> 00:06:23,640 Speaker 1: good subwoffer will create vibrations that you can physically feel. 104 00:06:24,400 --> 00:06:27,560 Speaker 1: They might be below the threshold for human hearing, which 105 00:06:27,600 --> 00:06:31,880 Speaker 1: is typically defined as anything between twenty hurts to twenty 106 00:06:32,040 --> 00:06:36,559 Speaker 1: thousand hurts in frequencies. They can also handle the lower 107 00:06:36,600 --> 00:06:40,159 Speaker 1: frequencies that, while not sternham shaking, are lower than what 108 00:06:40,200 --> 00:06:43,520 Speaker 1: your typical speaker can handle, and thus they fill out 109 00:06:43,720 --> 00:06:46,479 Speaker 1: the sound that you will hear. Otherwise you would be 110 00:06:46,520 --> 00:06:51,280 Speaker 1: missing all those low low ends. This is important not 111 00:06:51,360 --> 00:06:54,400 Speaker 1: just for movies and television, but also for music. If 112 00:06:54,400 --> 00:06:56,279 Speaker 1: you've ever listened to music on a cheap pair of 113 00:06:56,320 --> 00:07:00,160 Speaker 1: headphones and thought, wow, this doesn't sound really that good, well, 114 00:07:00,240 --> 00:07:02,680 Speaker 1: chances are one of the issues that that those cheap 115 00:07:02,720 --> 00:07:06,159 Speaker 1: headphones have is that they're not reproducing all the frequencies 116 00:07:06,200 --> 00:07:09,200 Speaker 1: that are actually present in the music, so it's like 117 00:07:09,200 --> 00:07:12,440 Speaker 1: you're getting a narrow slice of what the music is, 118 00:07:13,120 --> 00:07:17,560 Speaker 1: not the full audio experience. Now, subliffers don't need to 119 00:07:17,560 --> 00:07:20,560 Speaker 1: be as directional as other speakers, so you don't have 120 00:07:20,640 --> 00:07:23,360 Speaker 1: to have them sitting in a very specific spot in 121 00:07:23,400 --> 00:07:25,960 Speaker 1: your setup the way you do with like your front 122 00:07:26,040 --> 00:07:28,120 Speaker 1: left and front right and center speakers and all that 123 00:07:28,160 --> 00:07:31,760 Speaker 1: kind of stuff. However, depending upon the size and shape 124 00:07:31,800 --> 00:07:35,320 Speaker 1: of your home theater space, you might actually need more 125 00:07:35,360 --> 00:07:38,560 Speaker 1: than one sub wiffer to create the effects you want. 126 00:07:38,800 --> 00:07:41,680 Speaker 1: Otherwise you could find out that the base distribution in 127 00:07:41,720 --> 00:07:43,760 Speaker 1: your home theater set up isn't quite up to par 128 00:07:44,480 --> 00:07:47,040 Speaker 1: and that there are some maybe some dead spots in 129 00:07:47,040 --> 00:07:51,280 Speaker 1: that space. Now, I've looked at a lot of surround 130 00:07:51,400 --> 00:07:55,240 Speaker 1: sound speaker setups, and many of the higher end ones 131 00:07:55,560 --> 00:07:58,600 Speaker 1: have two sub wiffers. And I should add that these 132 00:07:58,640 --> 00:08:02,640 Speaker 1: are well outside my ice range and probably outside most 133 00:08:02,680 --> 00:08:05,360 Speaker 1: people's price range unless you got like ten or twelve grand, 134 00:08:05,440 --> 00:08:08,960 Speaker 1: just burning a hole in your very very large pockets. 135 00:08:09,640 --> 00:08:12,920 Speaker 1: But you can see things like you know, nine point 136 00:08:12,960 --> 00:08:16,280 Speaker 1: two point two, and you know, these crazy systems that 137 00:08:16,680 --> 00:08:19,440 Speaker 1: get to a point where you're thinking, how many speakers 138 00:08:19,440 --> 00:08:23,000 Speaker 1: do you actually need? Apparently for some home theater enthusiasts, 139 00:08:23,040 --> 00:08:25,440 Speaker 1: it's going to always be there will never be enough speakers. 140 00:08:25,960 --> 00:08:28,680 Speaker 1: Now I think of anything, this discussion really shows that 141 00:08:28,720 --> 00:08:32,560 Speaker 1: your physical space matters a lot when it comes to 142 00:08:32,679 --> 00:08:36,040 Speaker 1: building out your home theater. If you want surround sound, 143 00:08:36,559 --> 00:08:38,520 Speaker 1: you need the space to be able to do it, 144 00:08:38,880 --> 00:08:41,839 Speaker 1: and you need to set up speakers according to which 145 00:08:42,360 --> 00:08:45,360 Speaker 1: version of surround sound you're going with. That also means 146 00:08:45,400 --> 00:08:49,000 Speaker 1: figuring out stuff like cable management. Now there are wireless 147 00:08:49,040 --> 00:08:52,040 Speaker 1: home theater systems where you've got like wireless speakers. Some 148 00:08:52,160 --> 00:08:55,000 Speaker 1: of them are really really good. When they first came out, 149 00:08:55,040 --> 00:08:58,520 Speaker 1: wireless speakers were kind of looked down upon because the 150 00:08:58,520 --> 00:09:01,000 Speaker 1: thought was that if you didn't have a physical wire 151 00:09:01,080 --> 00:09:05,600 Speaker 1: connecting your components, it could not possibly deliver the same 152 00:09:05,720 --> 00:09:08,000 Speaker 1: level of experience. But we've gotten a lot better with 153 00:09:08,040 --> 00:09:12,080 Speaker 1: those over the years. However, you know some systems still 154 00:09:12,160 --> 00:09:15,320 Speaker 1: just use physical wires to connect everything like speakers back 155 00:09:15,360 --> 00:09:18,720 Speaker 1: to the mixer. Then you know, sub whiffers might need 156 00:09:18,760 --> 00:09:21,480 Speaker 1: their own power cable and everything. So whichever set up 157 00:09:21,520 --> 00:09:24,199 Speaker 1: you go with, you need to take all this into consideration. 158 00:09:24,600 --> 00:09:27,480 Speaker 1: Cable management becomes a real high priority as you don't 159 00:09:27,480 --> 00:09:30,480 Speaker 1: want to trip over cables or have unsightly wires all 160 00:09:30,480 --> 00:09:34,199 Speaker 1: over the place. So that you know, one more thing 161 00:09:34,240 --> 00:09:36,800 Speaker 1: for you to keep in mind. Now you might also 162 00:09:36,840 --> 00:09:40,800 Speaker 1: think that seven point one, where you've got seven speakers 163 00:09:40,920 --> 00:09:44,320 Speaker 1: plus a sub wiffer like Dolby Atmos, is one of 164 00:09:44,320 --> 00:09:46,560 Speaker 1: those kind of levels, although they sometimes call it five 165 00:09:46,559 --> 00:09:50,000 Speaker 1: point one point two, because you've got the five speakers 166 00:09:50,040 --> 00:09:53,240 Speaker 1: of your typical surround sound set up, you've got your subwhiffer, 167 00:09:53,320 --> 00:09:56,720 Speaker 1: that's the one, and then you've got to atmost speakers 168 00:09:56,720 --> 00:09:59,840 Speaker 1: that are projecting above you. That's the point to. Anyway, 169 00:09:59,840 --> 00:10:01,760 Speaker 1: you might think that a seven point one set up 170 00:10:01,880 --> 00:10:05,360 Speaker 1: is inherently superior to a five point one set up, 171 00:10:05,679 --> 00:10:08,680 Speaker 1: which is far more common, but that is not necessarily 172 00:10:08,679 --> 00:10:12,200 Speaker 1: the case. The quality of the tech, as in how 173 00:10:12,240 --> 00:10:15,559 Speaker 1: good your mixer and receiver are, how good the speakers are, 174 00:10:15,640 --> 00:10:19,000 Speaker 1: and to some degree the cables. All of that matters. 175 00:10:19,040 --> 00:10:22,160 Speaker 1: But that cables thing is a huge caveat because there 176 00:10:22,160 --> 00:10:24,560 Speaker 1: are companies out there that market high end cables that 177 00:10:24,640 --> 00:10:28,760 Speaker 1: really don't deliver any perceptible benefit to the experience. We'll 178 00:10:28,800 --> 00:10:31,960 Speaker 1: talk a lot more about it later on. In fact, 179 00:10:32,040 --> 00:10:33,760 Speaker 1: really when it comes to cables, the rule of thumb 180 00:10:33,800 --> 00:10:37,120 Speaker 1: is that super cheap cables aren't great. They tend to 181 00:10:37,120 --> 00:10:40,080 Speaker 1: have bad insulation, and we'll talk more about that a 182 00:10:40,120 --> 00:10:43,320 Speaker 1: bit later too, But anything else is pretty much okay, 183 00:10:43,400 --> 00:10:45,640 Speaker 1: unless you're just having to run miles of cable, in 184 00:10:45,640 --> 00:10:47,800 Speaker 1: which case you might need to think more carefully about 185 00:10:47,800 --> 00:10:51,160 Speaker 1: your options. Also, I should add that in the world 186 00:10:51,160 --> 00:10:56,440 Speaker 1: of audio, there's this obsessive pursuit among audio files about 187 00:10:56,480 --> 00:10:59,880 Speaker 1: going after the most pure or true replication of sound, 188 00:11:00,280 --> 00:11:02,560 Speaker 1: and I get that, but I also get that a 189 00:11:02,600 --> 00:11:05,959 Speaker 1: lot of that comes down to stuff that is beyond 190 00:11:06,080 --> 00:11:10,040 Speaker 1: human perception and comes down to personal preference and psychology. 191 00:11:10,120 --> 00:11:13,480 Speaker 1: It's subjective in other words, like if you walked into 192 00:11:13,520 --> 00:11:16,920 Speaker 1: a room and you were told that this room was 193 00:11:16,960 --> 00:11:21,600 Speaker 1: outfitted with a high end, extremely expensive system, and it 194 00:11:21,679 --> 00:11:23,640 Speaker 1: turned out that really, in the background it was just 195 00:11:23,679 --> 00:11:26,240 Speaker 1: a good system, but not like a super crazy one, 196 00:11:27,040 --> 00:11:29,720 Speaker 1: well you might walk away thinking it was a life 197 00:11:29,800 --> 00:11:33,000 Speaker 1: changing experience, like you might come away from it saying wow, 198 00:11:33,320 --> 00:11:35,960 Speaker 1: that really makes a difference. Likewise, if you were to 199 00:11:35,960 --> 00:11:38,760 Speaker 1: walk into a space that had a really super high 200 00:11:38,840 --> 00:11:41,560 Speaker 1: end audio system, but you were told that you were 201 00:11:41,559 --> 00:11:44,120 Speaker 1: going to be listening to a budget model, you might 202 00:11:44,160 --> 00:11:49,000 Speaker 1: just think it's just okay. So typically, double blind studies 203 00:11:49,240 --> 00:11:53,520 Speaker 1: where neither the person experiencing a test nor the person 204 00:11:53,559 --> 00:11:57,040 Speaker 1: administering the test actually knows what kind of system is 205 00:11:57,080 --> 00:12:00,600 Speaker 1: being used. A lot of those show that beyond a 206 00:12:00,640 --> 00:12:04,839 Speaker 1: certain level of quality, our ability to discern different distinctions 207 00:12:05,440 --> 00:12:08,800 Speaker 1: diminishes quickly. So while a system might at least by 208 00:12:08,920 --> 00:12:12,720 Speaker 1: you know, finally tuned measurements and specifications say it's better, 209 00:12:13,400 --> 00:12:16,079 Speaker 1: you might not ever notice it because of the limitations 210 00:12:16,120 --> 00:12:20,400 Speaker 1: of human perception. So, in other words, don't buy the malarkey, 211 00:12:20,520 --> 00:12:24,080 Speaker 1: is what I'm saying. I guess. Oh, and like stereo, 212 00:12:24,559 --> 00:12:28,520 Speaker 1: your ability to enjoy surround sound depends upon what you're consuming. 213 00:12:28,800 --> 00:12:30,920 Speaker 1: So let's say you've picked up a Blu ray of 214 00:12:30,960 --> 00:12:33,920 Speaker 1: your favorite film and you see it supports Dolby five 215 00:12:33,920 --> 00:12:36,040 Speaker 1: point one surround sound, and you've got a five point 216 00:12:36,080 --> 00:12:39,080 Speaker 1: one system that supports Dolby. Well, that should be a 217 00:12:39,080 --> 00:12:42,000 Speaker 1: pretty good experience. It should sound great. But what I 218 00:12:42,120 --> 00:12:45,720 Speaker 1: You've got a seven point one system, but the media 219 00:12:45,800 --> 00:12:48,480 Speaker 1: you're looking at doesn't support seven point one. It's five 220 00:12:48,520 --> 00:12:52,280 Speaker 1: point one. Well, through technologies like Dolby pro Logic too 221 00:12:52,679 --> 00:12:56,160 Speaker 1: X or digital sound processing, which a lot of these 222 00:12:56,200 --> 00:13:00,480 Speaker 1: systems have built into them, whether it's your receiver or 223 00:13:00,520 --> 00:13:05,040 Speaker 1: your media player or whatever, well, then your system can 224 00:13:05,080 --> 00:13:08,439 Speaker 1: expand five point one soundtracks to meet the seven point 225 00:13:08,520 --> 00:13:11,280 Speaker 1: one channels, and to go into how all that works 226 00:13:11,280 --> 00:13:14,480 Speaker 1: would probably require a full episode, and let me just 227 00:13:14,520 --> 00:13:17,040 Speaker 1: be straight with you guys, it would also require an 228 00:13:17,120 --> 00:13:20,080 Speaker 1: expert on the subject matter because it quickly goes beyond 229 00:13:20,120 --> 00:13:23,439 Speaker 1: my own understanding. But in a way, it's kind of 230 00:13:23,480 --> 00:13:26,800 Speaker 1: like how four K and eight K television's upscale video 231 00:13:26,840 --> 00:13:32,880 Speaker 1: sources that aren't natively in ultra high definition. Now, one 232 00:13:32,920 --> 00:13:36,800 Speaker 1: thing I have not covered is sound bars. So these 233 00:13:36,840 --> 00:13:40,040 Speaker 1: are those wide, horizontal speakers you find in a lot 234 00:13:40,160 --> 00:13:42,680 Speaker 1: of sound setups these days. Are usually pretty short, and 235 00:13:42,720 --> 00:13:46,200 Speaker 1: they can typically fit directly in front of and underneath 236 00:13:46,200 --> 00:13:48,439 Speaker 1: a TV screen. So if you've got your TV screen 237 00:13:48,440 --> 00:13:51,400 Speaker 1: on the stand, this is that bar that would sit 238 00:13:51,440 --> 00:13:54,960 Speaker 1: in front of the TV and and act as a 239 00:13:55,120 --> 00:13:58,640 Speaker 1: very large or very wide speaker. And it's it's an 240 00:13:58,640 --> 00:14:02,679 Speaker 1: attempt to replicate the experience of surround sound through one 241 00:14:02,880 --> 00:14:05,800 Speaker 1: array of speakers inside a bar, instead of having a 242 00:14:05,800 --> 00:14:09,079 Speaker 1: bunch of separate units mounted around a seating space. So 243 00:14:10,120 --> 00:14:14,040 Speaker 1: within a sound bar are multiple speaker drivers, and some 244 00:14:14,080 --> 00:14:16,679 Speaker 1: of these might be pointed so that they push sound 245 00:14:16,679 --> 00:14:19,480 Speaker 1: out at an angle from the viewers, So instead of 246 00:14:19,480 --> 00:14:22,960 Speaker 1: it just being like an array of speakers all pointed 247 00:14:22,960 --> 00:14:25,640 Speaker 1: directly at you. Some of them might be pointed off 248 00:14:25,680 --> 00:14:28,240 Speaker 1: at an angle, with the idea being that the sound 249 00:14:28,280 --> 00:14:31,720 Speaker 1: is supposed to bounce off the walls to either side 250 00:14:31,720 --> 00:14:34,000 Speaker 1: of you and then come at you from a different 251 00:14:34,040 --> 00:14:38,640 Speaker 1: direction to simulate surround sound that way, So instead of 252 00:14:38,720 --> 00:14:41,760 Speaker 1: mounting a speaker you know a certain number of degrees 253 00:14:41,760 --> 00:14:44,360 Speaker 1: off to your right and to your left, you're using 254 00:14:44,440 --> 00:14:47,360 Speaker 1: the sound bar to bounce sound off walls so that 255 00:14:47,440 --> 00:14:50,800 Speaker 1: it comes to you that way anyway, So the channel 256 00:14:50,800 --> 00:14:52,640 Speaker 1: that might be meant for the front left, for example, 257 00:14:52,720 --> 00:14:55,480 Speaker 1: can beam off to the left of the viewer, hit 258 00:14:55,520 --> 00:14:58,440 Speaker 1: a wall, bounce back, and hit you at the right angle. 259 00:14:58,640 --> 00:15:00,760 Speaker 1: Of course, we all know that the law of reflection 260 00:15:00,840 --> 00:15:03,440 Speaker 1: tells us that the angle the sound will take after 261 00:15:03,520 --> 00:15:07,400 Speaker 1: the bounce is equal to the incoming angle, which means 262 00:15:07,440 --> 00:15:10,080 Speaker 1: that the distance between the sound bar and your walls 263 00:15:10,120 --> 00:15:12,600 Speaker 1: will matter. So if your television happens to be closer 264 00:15:12,640 --> 00:15:15,440 Speaker 1: to one side of the room than the other, like 265 00:15:15,480 --> 00:15:17,160 Speaker 1: if it's a little closer to the right than it 266 00:15:17,240 --> 00:15:19,640 Speaker 1: is to the left, well, that means that the channels 267 00:15:19,680 --> 00:15:21,400 Speaker 1: from the left and right are going to be bouncing 268 00:15:21,400 --> 00:15:24,840 Speaker 1: off at slightly different points on their respective walls, so 269 00:15:25,080 --> 00:15:28,840 Speaker 1: you might not get a really immersive surround sound effect 270 00:15:29,120 --> 00:15:32,080 Speaker 1: like I have a sound bar in my setup, but 271 00:15:32,160 --> 00:15:36,280 Speaker 1: my setup also my living room's weird, y'all. It is 272 00:15:36,320 --> 00:15:41,080 Speaker 1: open to the dining room and kitchen on the left side, 273 00:15:41,280 --> 00:15:44,080 Speaker 1: and the right side ends at a wall with windows 274 00:15:44,120 --> 00:15:46,840 Speaker 1: on it, so that means that you know, stuff can 275 00:15:46,840 --> 00:15:49,680 Speaker 1: bounce off to the right and hit that wall, But 276 00:15:49,800 --> 00:15:51,600 Speaker 1: if it goes off to the left, it's going all 277 00:15:51,640 --> 00:15:54,440 Speaker 1: the way towards the dining room and kitchen, so there's 278 00:15:54,440 --> 00:15:56,400 Speaker 1: no there's no wall for it to bounce off off, 279 00:15:56,440 --> 00:15:59,520 Speaker 1: so I don't get that effect. In addition, some sound 280 00:15:59,520 --> 00:16:01,680 Speaker 1: bars even come with speakers that aim at an angle 281 00:16:01,800 --> 00:16:05,400 Speaker 1: up towards the ceiling to get you that Dollby Atmos effects, 282 00:16:05,440 --> 00:16:08,040 Speaker 1: so the sound reflects off your ceiling and back down 283 00:16:08,080 --> 00:16:11,320 Speaker 1: towards where you're sitting. And generally speaking, sound bars are 284 00:16:11,400 --> 00:16:13,560 Speaker 1: much easier to set up because I mean, there's usually 285 00:16:13,560 --> 00:16:16,640 Speaker 1: only two components to the system. There's the sound bar 286 00:16:17,240 --> 00:16:21,840 Speaker 1: and there's a subwhiffer. Some somewhoffers also serve as receivers, 287 00:16:21,840 --> 00:16:24,800 Speaker 1: which will talk more about in a bit, so like 288 00:16:25,240 --> 00:16:28,560 Speaker 1: my system is that way. My subwhiffer is also my receiver, 289 00:16:29,120 --> 00:16:31,080 Speaker 1: and so I just have two units and that makes 290 00:16:31,080 --> 00:16:34,920 Speaker 1: it really simple. They can provide much better sound than 291 00:16:34,960 --> 00:16:38,000 Speaker 1: just a television alone can by itself, and in the 292 00:16:38,080 --> 00:16:41,440 Speaker 1: right room, it can be a really immersive experience. Not 293 00:16:41,520 --> 00:16:44,720 Speaker 1: so much for mine, but you know it's okay. Um, 294 00:16:44,760 --> 00:16:46,960 Speaker 1: if you aren't lucky enough to have a symmetrical space 295 00:16:47,000 --> 00:16:50,000 Speaker 1: perfectly set up for a home theater, then they don't 296 00:16:50,080 --> 00:16:53,800 Speaker 1: deliver quite that surround sound experience you might be hoping for. 297 00:16:54,440 --> 00:16:56,560 Speaker 1: So again, the space you are in is going to 298 00:16:56,600 --> 00:16:59,280 Speaker 1: have a big impact on your experience, and it's really 299 00:16:59,280 --> 00:17:02,280 Speaker 1: worth taking a good look at what you're working with 300 00:17:02,440 --> 00:17:05,359 Speaker 1: before you go on a very expensive shopping spree. I 301 00:17:05,400 --> 00:17:08,880 Speaker 1: would recommend getting someone from a company that builds out 302 00:17:08,920 --> 00:17:11,960 Speaker 1: home theater systems to consult with you on it. However, 303 00:17:12,440 --> 00:17:17,040 Speaker 1: I hesitate to make that just a blanket recommendation because 304 00:17:17,960 --> 00:17:19,840 Speaker 1: I mean, you also need to do your own research, 305 00:17:20,080 --> 00:17:23,720 Speaker 1: because I'm not saying that everyone out there is going 306 00:17:23,760 --> 00:17:26,399 Speaker 1: to try and steer you toward the most expensive system 307 00:17:26,440 --> 00:17:29,560 Speaker 1: you could possibly buy because they happen to work on commission. 308 00:17:31,160 --> 00:17:34,720 Speaker 1: But it's a possibility and it's good to be aware 309 00:17:34,760 --> 00:17:36,600 Speaker 1: of it. Now. I think that's a pretty good stopping 310 00:17:36,600 --> 00:17:39,480 Speaker 1: point for audio in general, although we'll obviously touch on 311 00:17:39,520 --> 00:17:42,840 Speaker 1: it some more later. So we're gonna talk about receivers 312 00:17:43,240 --> 00:17:54,119 Speaker 1: after we come back from this quick break. So a 313 00:17:54,160 --> 00:17:57,440 Speaker 1: lot of home theater setups include at a V receiver 314 00:17:57,600 --> 00:18:00,959 Speaker 1: and audio video receiver, and the receiver really has a 315 00:18:01,040 --> 00:18:03,919 Speaker 1: couple of big jobs. One of those is that it 316 00:18:03,960 --> 00:18:07,640 Speaker 1: acts as an amplifier, So it takes audio signals from 317 00:18:07,840 --> 00:18:13,320 Speaker 1: various media sources and it boosts those signals. It amplifies 318 00:18:13,400 --> 00:18:17,439 Speaker 1: them before sending them onto the appropriate speakers. Uh, the 319 00:18:17,520 --> 00:18:21,320 Speaker 1: output of audio signals from a media source might not 320 00:18:21,400 --> 00:18:25,719 Speaker 1: be strong enough to really power the speakers sufficiently, so 321 00:18:25,880 --> 00:18:30,480 Speaker 1: that's why you need an amplifier. But there's another really 322 00:18:30,520 --> 00:18:34,760 Speaker 1: important job that the receiver does, and that's that it 323 00:18:34,840 --> 00:18:38,480 Speaker 1: acts kind of like a media switch. So if you 324 00:18:38,520 --> 00:18:41,119 Speaker 1: have a lot of components connecting to your home theater system, 325 00:18:41,480 --> 00:18:46,080 Speaker 1: Let's say you've got an antenna and maybe a cable connection, 326 00:18:46,600 --> 00:18:50,320 Speaker 1: and maybe video game console and perhaps a different type 327 00:18:50,320 --> 00:18:53,639 Speaker 1: of set top box that's providing content. Maybe it's a 328 00:18:53,640 --> 00:18:57,960 Speaker 1: Blu ray player or something um or maybe it's you know, 329 00:18:58,040 --> 00:19:03,080 Speaker 1: a streaming service box or something. Then this can act 330 00:19:03,160 --> 00:19:06,160 Speaker 1: as like the switch between all those different sources so 331 00:19:06,200 --> 00:19:09,760 Speaker 1: that you can have the right stuff being sent to 332 00:19:09,800 --> 00:19:12,840 Speaker 1: your television screen and to all your speakers. So the 333 00:19:12,880 --> 00:19:15,160 Speaker 1: a V receiver kind of acts like a nexus point 334 00:19:15,240 --> 00:19:18,200 Speaker 1: for all of that stuff. You would plug all the 335 00:19:18,240 --> 00:19:22,480 Speaker 1: inputs into the a V receiver and then you would 336 00:19:22,560 --> 00:19:25,399 Speaker 1: use a single connection to connect your a V receiver 337 00:19:25,520 --> 00:19:28,480 Speaker 1: to something like your television or a different one to 338 00:19:28,480 --> 00:19:32,679 Speaker 1: connect to your speakers. That way, when you want to 339 00:19:32,680 --> 00:19:35,480 Speaker 1: watch say a U h D Blu Ray, you switch 340 00:19:35,560 --> 00:19:39,000 Speaker 1: the a V receiver to that setting to whatever you 341 00:19:39,040 --> 00:19:42,440 Speaker 1: know input devices you're using to watch that Blue ray on, 342 00:19:43,160 --> 00:19:46,760 Speaker 1: and the receiver essentially makes all the proper connections between 343 00:19:47,080 --> 00:19:51,840 Speaker 1: your Blu ray player and your television and speakers. Or 344 00:19:51,920 --> 00:19:53,920 Speaker 1: let's say you want to watch cable TV, while you 345 00:19:53,960 --> 00:19:56,320 Speaker 1: would switch to that setting on your a V receiver, 346 00:19:56,840 --> 00:20:00,280 Speaker 1: and then the cable feed would be what's going to 347 00:20:00,359 --> 00:20:03,320 Speaker 1: your television and to your speakers. And one big benefit 348 00:20:03,440 --> 00:20:06,320 Speaker 1: to this, and it sounds small, but trust me, it's 349 00:20:06,320 --> 00:20:09,480 Speaker 1: really nice, is that the a V receiver will plug 350 00:20:09,560 --> 00:20:14,119 Speaker 1: into one port in your television, one input typically you 351 00:20:14,160 --> 00:20:16,760 Speaker 1: do this using an HDMI cable, which we will talk 352 00:20:16,800 --> 00:20:19,600 Speaker 1: about a little bit later. And so let's say you 353 00:20:19,640 --> 00:20:22,199 Speaker 1: plug your a V receiver into h d M I 354 00:20:22,320 --> 00:20:26,000 Speaker 1: port number one on your television, and everything else is 355 00:20:26,000 --> 00:20:29,399 Speaker 1: going through your a V receiver to your TV. That 356 00:20:29,440 --> 00:20:31,879 Speaker 1: means when you switch from Blu ray to cable on 357 00:20:31,920 --> 00:20:34,480 Speaker 1: your a V receiver, you don't also have to switch 358 00:20:34,520 --> 00:20:39,040 Speaker 1: the input on your television. Now, I know that sounds small, 359 00:20:39,200 --> 00:20:42,199 Speaker 1: but trust me, I have seen so many situations in 360 00:20:42,200 --> 00:20:45,000 Speaker 1: which someone was not using an a V receiver, so 361 00:20:45,160 --> 00:20:47,920 Speaker 1: they had all of their different components connecting to their 362 00:20:47,960 --> 00:20:51,040 Speaker 1: television directly, and then they have to fuss around with 363 00:20:51,040 --> 00:20:53,560 Speaker 1: a remote control and try to figure out which input 364 00:20:53,760 --> 00:20:56,560 Speaker 1: on their television they needed to select in order to 365 00:20:56,600 --> 00:20:59,120 Speaker 1: make something specific happen. Like let's say they switched from 366 00:20:59,119 --> 00:21:02,240 Speaker 1: playing a video game and now they want to connect 367 00:21:02,280 --> 00:21:05,280 Speaker 1: to like a Roku or something. They would have to 368 00:21:05,800 --> 00:21:08,360 Speaker 1: go through and choose the correct input setting in order 369 00:21:08,400 --> 00:21:11,320 Speaker 1: to do that. Because they had each of these things 370 00:21:11,359 --> 00:21:16,400 Speaker 1: connecting to their television's directly, that can get a little frustrating. 371 00:21:16,680 --> 00:21:19,480 Speaker 1: It gets a little clunky. So reducing the number of 372 00:21:19,520 --> 00:21:22,120 Speaker 1: times you have to switch inputs on your television is 373 00:21:22,160 --> 00:21:26,840 Speaker 1: a pretty nice thing. Also, receivers tend to have radio tuners. 374 00:21:26,840 --> 00:21:29,320 Speaker 1: I mean they are receivers, they have radio tuners in them, 375 00:21:29,320 --> 00:21:33,400 Speaker 1: and sometimes they have satellite radio tuners. So either way 376 00:21:33,440 --> 00:21:35,959 Speaker 1: you have an added benefit there. You've got a device 377 00:21:36,040 --> 00:21:38,920 Speaker 1: that can pick up radio signals and you can listen 378 00:21:39,000 --> 00:21:41,560 Speaker 1: to radio on your home theater, you know, in case 379 00:21:41,560 --> 00:21:44,200 Speaker 1: you ever want to do that. A V receivers also 380 00:21:44,359 --> 00:21:47,719 Speaker 1: decode the surround sound signal formats that are on various 381 00:21:47,720 --> 00:21:51,680 Speaker 1: forms of media, and then that's how they make sure 382 00:21:51,760 --> 00:21:54,320 Speaker 1: that the right speakers are playing the right sounds. That 383 00:21:54,359 --> 00:21:56,560 Speaker 1: way you're getting, you know, the front left channel is 384 00:21:56,560 --> 00:21:58,639 Speaker 1: going to the front left speaker and it's not like 385 00:21:58,800 --> 00:22:01,840 Speaker 1: suddenly going to the center's speaker or something. That's another 386 00:22:01,880 --> 00:22:05,000 Speaker 1: important job receivers do. Now, there are some folks who 387 00:22:05,000 --> 00:22:08,119 Speaker 1: do forego the a V receiver. Typically they don't have 388 00:22:08,160 --> 00:22:10,960 Speaker 1: surround sound setups. As a result, they might have, you know, 389 00:22:11,119 --> 00:22:14,440 Speaker 1: simple stereo speakers hooked up to their television. So it's 390 00:22:14,440 --> 00:22:17,760 Speaker 1: not like an a V receiver is an absolute requirement, 391 00:22:17,960 --> 00:22:20,840 Speaker 1: but for a lot of serious home theater enthusiasts, they 392 00:22:20,880 --> 00:22:25,320 Speaker 1: consider it a critical component of their setup. Now let's 393 00:22:25,320 --> 00:22:28,800 Speaker 1: switch over and talk about media sources. So you've got 394 00:22:28,800 --> 00:22:31,960 Speaker 1: your television or your projector and screen, you've got your 395 00:22:31,960 --> 00:22:34,760 Speaker 1: sound system, you've got your a V receiver ready to 396 00:22:34,800 --> 00:22:38,359 Speaker 1: connect to everything to you know those other components. So 397 00:22:38,400 --> 00:22:40,960 Speaker 1: what are you putting on this thing? Like, how are 398 00:22:40,960 --> 00:22:45,920 Speaker 1: you getting the actual media to consume? Well, the good 399 00:22:45,960 --> 00:22:49,199 Speaker 1: news is you have way more options today than you 400 00:22:49,240 --> 00:22:52,960 Speaker 1: did when ultra high definition was first becoming a thing. Um, 401 00:22:53,080 --> 00:22:56,320 Speaker 1: since four KTVs are now kind of the standard in 402 00:22:56,440 --> 00:22:59,359 Speaker 1: most most stores, Like if you look at their television's, 403 00:22:59,400 --> 00:23:02,239 Speaker 1: four K is by far the thing that takes up 404 00:23:02,280 --> 00:23:05,960 Speaker 1: the most shelf space. Well, the first four KTVs hit 405 00:23:06,040 --> 00:23:08,639 Speaker 1: store shelves back in two thousand twelve, but at that 406 00:23:08,680 --> 00:23:13,760 Speaker 1: point there really wasn't any content for four KTVs. Like 407 00:23:13,800 --> 00:23:16,840 Speaker 1: you can still watch HD content, High definition content, or 408 00:23:16,840 --> 00:23:21,280 Speaker 1: even standard definition, but you couldn't find much four K content. 409 00:23:21,920 --> 00:23:24,880 Speaker 1: Buying a four K TV was more like future proofing 410 00:23:24,920 --> 00:23:28,560 Speaker 1: your home theater because you couldn't really enjoy content on 411 00:23:28,640 --> 00:23:31,880 Speaker 1: it right out of the box. And this has happened 412 00:23:32,240 --> 00:23:35,000 Speaker 1: multiple times before, like when h D t V first 413 00:23:35,000 --> 00:23:38,160 Speaker 1: became a thing, there actually wasn't that much HD content 414 00:23:38,240 --> 00:23:41,440 Speaker 1: to watch on that either you could find like an 415 00:23:41,560 --> 00:23:46,719 Speaker 1: hd TV promotional channel that would just run stuff like 416 00:23:47,280 --> 00:23:50,399 Speaker 1: nature scenes and maybe a couple of clips from like 417 00:23:51,000 --> 00:23:54,760 Speaker 1: specific sporting events or a sunset or sunrise. Like. There 418 00:23:54,760 --> 00:23:57,119 Speaker 1: were a lot of these kind of standard things that 419 00:23:57,160 --> 00:24:00,760 Speaker 1: were meant to show off how beautiful the screens, but 420 00:24:01,000 --> 00:24:04,200 Speaker 1: for real content there was a distinct lack, so there 421 00:24:04,280 --> 00:24:06,920 Speaker 1: was a bit of a gap between having the capability 422 00:24:06,960 --> 00:24:10,040 Speaker 1: to see stuff in higher resolution and actually having any 423 00:24:10,119 --> 00:24:14,640 Speaker 1: higher resolution media to watch. The first pay TV provider 424 00:24:14,640 --> 00:24:17,480 Speaker 1: in the United States to offer a limited selection of 425 00:24:17,480 --> 00:24:21,120 Speaker 1: four K content was the satellite TV provider Direct TV. 426 00:24:21,760 --> 00:24:25,200 Speaker 1: That was in two thousand fourteen. The first uh D 427 00:24:25,320 --> 00:24:28,080 Speaker 1: Blu ray players went on sale in North America in 428 00:24:28,080 --> 00:24:31,840 Speaker 1: two thousand sixteen, and luckily there were some media companies 429 00:24:31,880 --> 00:24:34,679 Speaker 1: making four K Blu ray discs as well, because again, 430 00:24:35,560 --> 00:24:37,560 Speaker 1: you know, it drives home the fact you need all 431 00:24:37,600 --> 00:24:39,880 Speaker 1: the pieces in the puzzle to match up to get 432 00:24:39,920 --> 00:24:42,919 Speaker 1: the experience you want. You can have a four K 433 00:24:43,080 --> 00:24:45,320 Speaker 1: TV and nothing to watch on it, or you could 434 00:24:45,359 --> 00:24:47,560 Speaker 1: have a four K Blu ray player, But if no 435 00:24:47,560 --> 00:24:50,399 Speaker 1: one's making four K Blu ray disks, that doesn't do 436 00:24:50,480 --> 00:24:51,800 Speaker 1: you a whole lot of good. I mean, you could 437 00:24:51,800 --> 00:24:55,320 Speaker 1: still probably watch standard Blu rays. But you know the 438 00:24:55,359 --> 00:24:58,880 Speaker 1: same thing with stuff like HDR high dynamic range. If 439 00:24:58,920 --> 00:25:02,520 Speaker 1: any piece of the puzz doesn't support HDR, then you're 440 00:25:02,560 --> 00:25:05,880 Speaker 1: not going to be able to take advantage of that technology. 441 00:25:05,920 --> 00:25:09,359 Speaker 1: These days, a lot of the four K content comes 442 00:25:09,440 --> 00:25:13,359 Speaker 1: from streaming services. So this means that your home theater 443 00:25:13,720 --> 00:25:18,200 Speaker 1: will need a connection to the Internet, either wirelessly or hardwired. 444 00:25:18,440 --> 00:25:21,240 Speaker 1: And a lot of televisions these days can connect directly 445 00:25:21,320 --> 00:25:25,480 Speaker 1: to a range of streaming sources without any additional equipment. 446 00:25:25,520 --> 00:25:28,600 Speaker 1: You know, the so called smart TVs that have these 447 00:25:29,160 --> 00:25:33,360 Speaker 1: these uh these interfaces built into them. The television will 448 00:25:33,400 --> 00:25:35,800 Speaker 1: have a user interface that lets you select stuff like 449 00:25:36,200 --> 00:25:42,359 Speaker 1: HBO Max, Netflix, Amazon Prime Video, Hulu, Disney Plus, Apple 450 00:25:42,440 --> 00:25:46,200 Speaker 1: TV YouTube. You know, these are the types of services, 451 00:25:46,200 --> 00:25:50,520 Speaker 1: and there are a few others that carry four K content. Now, 452 00:25:50,560 --> 00:25:54,000 Speaker 1: in some cases, in order to access that four K content, 453 00:25:54,960 --> 00:25:56,800 Speaker 1: you've got to actually pay a little bit more than 454 00:25:56,840 --> 00:26:00,320 Speaker 1: these standard subscription to those services. So, for Examp Apple 455 00:26:00,320 --> 00:26:02,600 Speaker 1: here in North America, if you wanted to watch four 456 00:26:02,680 --> 00:26:05,680 Speaker 1: K content on Netflix, you would need to shell out 457 00:26:05,720 --> 00:26:09,840 Speaker 1: the eighteen dollars a month for a premium subscription plan 458 00:26:09,920 --> 00:26:13,399 Speaker 1: in order to get that. Other services like Disney Plus 459 00:26:13,440 --> 00:26:16,760 Speaker 1: include four K content that even has hd R support 460 00:26:16,800 --> 00:26:20,560 Speaker 1: built into it right there at the basic subscription price. 461 00:26:21,000 --> 00:26:23,280 Speaker 1: But you do just have to have the system capable of, 462 00:26:23,320 --> 00:26:25,720 Speaker 1: you know, taking advantage of that. But you can, you 463 00:26:25,720 --> 00:26:27,639 Speaker 1: can do it right on the box. You don't, you 464 00:26:27,640 --> 00:26:30,480 Speaker 1: don't have to subscribe to a higher tier of service. 465 00:26:31,520 --> 00:26:34,959 Speaker 1: This also means that whatever device is connecting to the 466 00:26:35,000 --> 00:26:38,959 Speaker 1: service also needs to be compatible with that four K standard. Now, 467 00:26:39,000 --> 00:26:41,919 Speaker 1: if it's your television, then that's probably covered right. If 468 00:26:41,960 --> 00:26:44,399 Speaker 1: you bought a four K TV and it has these 469 00:26:44,880 --> 00:26:47,480 Speaker 1: uh these interfaces built in so that you can actually 470 00:26:47,560 --> 00:26:51,560 Speaker 1: directly access a Netflix through your television without any other 471 00:26:52,320 --> 00:26:55,720 Speaker 1: device needed, then you're good. But if it's an additional 472 00:26:55,800 --> 00:26:59,159 Speaker 1: set top box, like if it's a Roku, then that 473 00:26:59,240 --> 00:27:01,760 Speaker 1: device need to be four K compatible as well in 474 00:27:01,920 --> 00:27:04,040 Speaker 1: order to be able to watch this stuff. Most of 475 00:27:04,040 --> 00:27:07,280 Speaker 1: the more recent devices do meet that requirement, but if 476 00:27:07,280 --> 00:27:09,440 Speaker 1: you happen to be sitting on an older one, it's 477 00:27:09,440 --> 00:27:11,640 Speaker 1: always a good idea to take a quick look online 478 00:27:11,680 --> 00:27:15,560 Speaker 1: just to see what resolutions it supports. Um if it's 479 00:27:15,560 --> 00:27:19,359 Speaker 1: fairly recent you might be okay. For example, Roku started 480 00:27:19,400 --> 00:27:22,520 Speaker 1: offering devices with four K support back in October two 481 00:27:22,520 --> 00:27:26,520 Speaker 1: thousand fifteen, though not all devices Roku has made since 482 00:27:26,520 --> 00:27:30,000 Speaker 1: two thousand fifteen are four K compatible, so again, making 483 00:27:30,040 --> 00:27:33,679 Speaker 1: sure that everything meets the minimum standard that you're hoping 484 00:27:33,720 --> 00:27:38,160 Speaker 1: for is important. In addition to that, modern video game 485 00:27:38,160 --> 00:27:42,240 Speaker 1: consoles are four K compatible. This started with the PlayStation 486 00:27:42,280 --> 00:27:45,440 Speaker 1: four Pro and the Xbox one X and Xbox one 487 00:27:45,680 --> 00:27:49,880 Speaker 1: S models. Uh, the Xbox Series X and the PlayStation 488 00:27:50,000 --> 00:27:53,560 Speaker 1: five actually have eight K capability, so if you want 489 00:27:53,600 --> 00:27:56,680 Speaker 1: to really future proof your home theater and you want 490 00:27:56,680 --> 00:27:59,360 Speaker 1: a video game console to be part of it, you 491 00:27:59,400 --> 00:28:03,800 Speaker 1: could get one or both of those. Good luck, they 492 00:28:03,800 --> 00:28:06,240 Speaker 1: can still be pretty hard to find in most markets. 493 00:28:06,480 --> 00:28:09,920 Speaker 1: The PS five in particular, is tricky to find. Game 494 00:28:10,000 --> 00:28:13,359 Speaker 1: consoles like the PS five and Xbox Series X also 495 00:28:13,520 --> 00:28:16,480 Speaker 1: can serve as streaming devices, so if your TV doesn't 496 00:28:16,600 --> 00:28:20,280 Speaker 1: have that capability natively built into it and you don't 497 00:28:20,320 --> 00:28:22,800 Speaker 1: want to buy another set, top box consoles can pick 498 00:28:22,880 --> 00:28:26,160 Speaker 1: up that slack. All right, So let's recap for a second. 499 00:28:26,400 --> 00:28:29,760 Speaker 1: Your home theater is going to need media sources. You know, 500 00:28:29,840 --> 00:28:33,440 Speaker 1: something to watch you can get some four K material 501 00:28:33,520 --> 00:28:37,080 Speaker 1: through cable or satellite feeds, but it's a pretty limited amount. 502 00:28:37,480 --> 00:28:40,720 Speaker 1: So depending upon your provider, you'll have some stuff there 503 00:28:40,960 --> 00:28:43,960 Speaker 1: that will look and sound great on your system. Some 504 00:28:44,240 --> 00:28:49,920 Speaker 1: providers might only have on demand like pay videos that 505 00:28:50,000 --> 00:28:52,560 Speaker 1: you can access that that can take advantage of those 506 00:28:52,600 --> 00:28:56,080 Speaker 1: sort of systems. You can also stream content from the 507 00:28:56,120 --> 00:28:58,960 Speaker 1: Internet to your home theater, though I should add that 508 00:28:59,000 --> 00:29:02,120 Speaker 1: will require and least a pretty decent Internet connection of 509 00:29:02,120 --> 00:29:06,240 Speaker 1: at least megabits per second. You probably want to find 510 00:29:06,280 --> 00:29:08,800 Speaker 1: a plan that also has a really high data cap 511 00:29:08,920 --> 00:29:11,840 Speaker 1: or no data cap, because four K video can eat 512 00:29:11,920 --> 00:29:15,360 Speaker 1: up a lot of that data allowance. Um Netflix estimated 513 00:29:15,400 --> 00:29:18,640 Speaker 1: back in late that if you watched an hour of 514 00:29:18,720 --> 00:29:23,160 Speaker 1: four K video, it's equivalent to consuming about seven gigabytes 515 00:29:23,360 --> 00:29:27,280 Speaker 1: of data. That's just one hour of content. So if 516 00:29:27,320 --> 00:29:30,240 Speaker 1: you're someone who plans to use a home theater a lot, 517 00:29:30,600 --> 00:29:33,640 Speaker 1: and you're gonna lean heavily on streaming services to provide 518 00:29:33,640 --> 00:29:37,240 Speaker 1: four K content, you could be bumping up against some 519 00:29:37,320 --> 00:29:41,240 Speaker 1: data caps. Like Comcast has a data cap that seems 520 00:29:41,280 --> 00:29:45,240 Speaker 1: incredibly high. It's one point to terabytes. That's a huge 521 00:29:45,240 --> 00:29:48,360 Speaker 1: amount of data. But if you're a home theater fiend, 522 00:29:48,840 --> 00:29:51,280 Speaker 1: you can hit that after forty hours of watching uh 523 00:29:51,400 --> 00:29:53,680 Speaker 1: D content, So if you're gonna be doing it a lot, 524 00:29:54,920 --> 00:29:59,200 Speaker 1: that's something you could take into consideration. I think we 525 00:29:59,280 --> 00:30:03,280 Speaker 1: can now switch over to finally talk about cables, and 526 00:30:03,360 --> 00:30:06,560 Speaker 1: in a way, I think that cables has become a 527 00:30:06,600 --> 00:30:10,440 Speaker 1: little less confusing over time, maybe by a little bit. 528 00:30:11,200 --> 00:30:13,720 Speaker 1: So we'll do a quick recap on audio and video 529 00:30:13,840 --> 00:30:16,680 Speaker 1: cables to see where we came from, because I mean, 530 00:30:16,760 --> 00:30:20,800 Speaker 1: some home theater systems still use these legacy cables because 531 00:30:20,840 --> 00:30:24,280 Speaker 1: they still include legacy components. If you have like an 532 00:30:24,280 --> 00:30:26,600 Speaker 1: old VCR, for example, and you want to be able 533 00:30:26,640 --> 00:30:30,600 Speaker 1: to watch VCR cassettes, then you may need some of 534 00:30:30,640 --> 00:30:34,320 Speaker 1: these old cables. It also could probably mean that you're 535 00:30:34,360 --> 00:30:38,160 Speaker 1: gonna need some adapters in order to connect these older 536 00:30:38,520 --> 00:30:41,400 Speaker 1: devices to your newer television sets because a lot of 537 00:30:41,440 --> 00:30:48,840 Speaker 1: manufacturers stopped including those ports. Keep in mind, the the 538 00:30:49,080 --> 00:30:50,960 Speaker 1: like I said, the stuff I'm talking about right now 539 00:30:51,080 --> 00:30:55,080 Speaker 1: or the I'll start talking about, is really mostly obsolete. Um, 540 00:30:55,360 --> 00:31:00,680 Speaker 1: so this is more for completion sake than anything else. 541 00:31:01,320 --> 00:31:05,200 Speaker 1: First off, let's mention coaxial cables, because these are pretty common. 542 00:31:05,280 --> 00:31:08,360 Speaker 1: These are those cables with the copper connectors. They typically 543 00:31:08,360 --> 00:31:14,480 Speaker 1: have black cladding. They're fairly thick and not always super flexible. UH. 544 00:31:14,560 --> 00:31:18,200 Speaker 1: You usually use these to connect from your cable outlet 545 00:31:18,280 --> 00:31:21,960 Speaker 1: to a cable box or maybe a satellite connector, and 546 00:31:22,080 --> 00:31:24,480 Speaker 1: you might even use one to connect from the cable 547 00:31:24,520 --> 00:31:28,280 Speaker 1: box to your television. UH. These cable send audio and 548 00:31:28,440 --> 00:31:33,160 Speaker 1: video signals both. However, they're really only good at carrying 549 00:31:33,160 --> 00:31:35,640 Speaker 1: resolutions of up to ten eight on them, so they 550 00:31:35,720 --> 00:31:38,840 Speaker 1: can carry up to h D t V quality, but 551 00:31:38,960 --> 00:31:43,080 Speaker 1: not four K UH, and that's a problem. It means 552 00:31:43,120 --> 00:31:44,719 Speaker 1: that you have to have a different kind of connection 553 00:31:44,760 --> 00:31:49,360 Speaker 1: if you want to get four K quality video streaming 554 00:31:49,640 --> 00:31:54,200 Speaker 1: to your your system. But let's talk about some other 555 00:31:54,280 --> 00:31:58,200 Speaker 1: types of audio and video cables. So way back in 556 00:31:58,240 --> 00:32:00,440 Speaker 1: the day, when you've got something like, you know, a 557 00:32:00,480 --> 00:32:03,680 Speaker 1: game console, you would typically have a cable that would 558 00:32:03,800 --> 00:32:06,880 Speaker 1: end in three connectors. And I'm starting with our c 559 00:32:07,040 --> 00:32:10,400 Speaker 1: A connectors that could go even further back, but we 560 00:32:10,480 --> 00:32:13,400 Speaker 1: have to draw the line somewhere. So you would have 561 00:32:13,600 --> 00:32:16,520 Speaker 1: three connectors, one that was red, one that was white, 562 00:32:16,840 --> 00:32:19,360 Speaker 1: and one that was yellow, and they all had little 563 00:32:19,680 --> 00:32:22,720 Speaker 1: like copper plugs sticking out of them. These were r 564 00:32:22,800 --> 00:32:25,840 Speaker 1: c A connector cables, so called because the company r 565 00:32:25,880 --> 00:32:28,400 Speaker 1: c A developed them, and the red and white cables 566 00:32:28,400 --> 00:32:31,400 Speaker 1: were actually just for audio. The red cable carried the 567 00:32:31,440 --> 00:32:34,880 Speaker 1: audio channel for the right speaker, and the white cable 568 00:32:35,040 --> 00:32:39,120 Speaker 1: carried the audio channel for the left speaker. That left 569 00:32:39,120 --> 00:32:42,360 Speaker 1: the yellow cable to carry all the video signal all 570 00:32:42,440 --> 00:32:46,920 Speaker 1: bides lonesome, and we called it composite video. This yellow 571 00:32:47,000 --> 00:32:50,000 Speaker 1: cable only had the capability to carry video signals of 572 00:32:50,080 --> 00:32:53,560 Speaker 1: standard definition, so that meant it was either four eight 573 00:32:53,920 --> 00:32:56,280 Speaker 1: or five seventy six, depending on whether you were in 574 00:32:56,480 --> 00:32:59,800 Speaker 1: like the United States or you know, Europe. So using 575 00:32:59,840 --> 00:33:04,200 Speaker 1: the cable, even if the source somehow could put out 576 00:33:04,400 --> 00:33:07,840 Speaker 1: HD content, the cable would not be able to carry 577 00:33:07,880 --> 00:33:10,360 Speaker 1: that to a television. The best you can manage is 578 00:33:10,520 --> 00:33:15,920 Speaker 1: standard definition resolution. Then we get s video cables. These 579 00:33:15,960 --> 00:33:19,200 Speaker 1: were an improvement over a composite video. It was a 580 00:33:19,240 --> 00:33:22,800 Speaker 1: single again, a single cable, but it was not an 581 00:33:22,920 --> 00:33:26,680 Speaker 1: enormous leap in quality. They could still only carry standard 582 00:33:26,720 --> 00:33:30,160 Speaker 1: definition resolution signals, so still you're limited to four a 583 00:33:30,280 --> 00:33:34,600 Speaker 1: D or five sony six in resolution. But the composite 584 00:33:34,760 --> 00:33:38,320 Speaker 1: video cable would crunch all the video information into a 585 00:33:38,400 --> 00:33:43,240 Speaker 1: single signal across a single wire. S video cables actually 586 00:33:43,240 --> 00:33:48,760 Speaker 1: had two separate wires to carry information to the display, 587 00:33:48,840 --> 00:33:52,320 Speaker 1: and you would have one wire carrying the information that 588 00:33:52,400 --> 00:33:56,320 Speaker 1: relates to the color of the signal, and the other 589 00:33:56,360 --> 00:33:59,720 Speaker 1: wire would carry the information relating to the brightness of 590 00:33:59,720 --> 00:34:03,120 Speaker 1: the signal. And by separating this out, the S video 591 00:34:03,240 --> 00:34:06,880 Speaker 1: cable could deliver a higher quality set of signals to 592 00:34:06,880 --> 00:34:11,160 Speaker 1: a television. Now, the resolution wasn't like magically better, but 593 00:34:11,280 --> 00:34:14,120 Speaker 1: the quality of the colors and the subtle shifts and 594 00:34:14,160 --> 00:34:17,480 Speaker 1: brightness were better, so you did get a better picture, 595 00:34:17,760 --> 00:34:21,400 Speaker 1: just not necessarily a more detailed picture, at least not 596 00:34:22,320 --> 00:34:25,760 Speaker 1: detailed informs in the form of resolution. This is another 597 00:34:25,800 --> 00:34:29,440 Speaker 1: reminder that resolution isn't the end all bell. It's a 598 00:34:29,520 --> 00:34:32,799 Speaker 1: very important part, but it's just one component as to 599 00:34:33,040 --> 00:34:36,440 Speaker 1: you know, the quality of an image. S video cables 600 00:34:36,480 --> 00:34:39,760 Speaker 1: only carried video information, so you still needed separate cables 601 00:34:39,800 --> 00:34:43,040 Speaker 1: to carry audio to speakers, so those white and red 602 00:34:43,080 --> 00:34:46,279 Speaker 1: wires would stick around. Also, S video didn't get a 603 00:34:46,320 --> 00:34:48,960 Speaker 1: real good chance to take off because of a superior 604 00:34:49,040 --> 00:34:52,799 Speaker 1: technology that came out around the same time. And I'll 605 00:34:52,800 --> 00:34:56,439 Speaker 1: talk more about what that was after we take this 606 00:34:56,560 --> 00:35:08,279 Speaker 1: quick break. Okay. One other set of cables that had 607 00:35:09,280 --> 00:35:13,040 Speaker 1: a fair amount of popularity briefly at longer in the 608 00:35:13,080 --> 00:35:18,440 Speaker 1: home theater space for real enthusiasts were component video cables. 609 00:35:18,480 --> 00:35:21,480 Speaker 1: And I know this gets confusing. You've got composite video. 610 00:35:21,719 --> 00:35:24,560 Speaker 1: That's that our c A cable that had the yellow 611 00:35:24,600 --> 00:35:27,480 Speaker 1: into it that carried all the video. Then you had 612 00:35:27,960 --> 00:35:32,279 Speaker 1: component video cables. These in the United States anyway, came 613 00:35:32,280 --> 00:35:35,239 Speaker 1: in sets of three, similar to our c a composite 614 00:35:35,239 --> 00:35:38,760 Speaker 1: connector cables, but instead of red, white and yellow, these 615 00:35:38,800 --> 00:35:43,120 Speaker 1: were red, blue, and green. And unlike composite and S 616 00:35:43,239 --> 00:35:47,600 Speaker 1: video cables, these could carry high definition video signals, so 617 00:35:47,640 --> 00:35:51,160 Speaker 1: you could actually get up to ten eight resolution using 618 00:35:51,200 --> 00:35:53,880 Speaker 1: these cables, assuming again that all the other components in 619 00:35:53,920 --> 00:35:58,760 Speaker 1: your system were compatible, that you had HDTV source of media, 620 00:35:59,000 --> 00:36:03,040 Speaker 1: and you had an hd TV compatible television. They did 621 00:36:03,040 --> 00:36:06,080 Speaker 1: not carry audio signals, so again you needed to have 622 00:36:06,160 --> 00:36:09,040 Speaker 1: separate cables to carry audio if you wanted to listen 623 00:36:09,080 --> 00:36:11,520 Speaker 1: to something more than just out of the television speakers. 624 00:36:11,920 --> 00:36:15,640 Speaker 1: And I should add that this was the common form 625 00:36:15,760 --> 00:36:19,400 Speaker 1: factor here in North America. Now in other parts of 626 00:36:19,440 --> 00:36:22,800 Speaker 1: the world, component video used different kinds of ports and cables, 627 00:36:23,080 --> 00:36:24,680 Speaker 1: But to go through all of that would be way 628 00:36:24,680 --> 00:36:28,319 Speaker 1: too much, so we're just going to leave it for now. Now, 629 00:36:28,400 --> 00:36:31,319 Speaker 1: you might think that because video signals relate back to 630 00:36:31,520 --> 00:36:34,600 Speaker 1: r g B being red, green, and blue, and that 631 00:36:34,640 --> 00:36:37,160 Speaker 1: you use combinations of those colors to create all the 632 00:36:37,200 --> 00:36:41,600 Speaker 1: other colors with video, that that would mean these cables 633 00:36:41,840 --> 00:36:45,359 Speaker 1: were each carrying signals for red, green, and blue. Right, 634 00:36:46,719 --> 00:36:49,960 Speaker 1: not quite um. It was a little different than that. 635 00:36:50,160 --> 00:36:52,760 Speaker 1: It did not quite break it down to that level. 636 00:36:52,800 --> 00:36:56,600 Speaker 1: So instead you had one cable. They carried the brightness 637 00:36:56,680 --> 00:37:00,719 Speaker 1: information for the pictures, so the luminosity or looma and 638 00:37:00,760 --> 00:37:04,279 Speaker 1: it also carried some synchronization information, but we won't get 639 00:37:04,320 --> 00:37:08,719 Speaker 1: into all the technical details there. Another cable carried information 640 00:37:08,760 --> 00:37:13,280 Speaker 1: about the difference between the luma the luminosity or brightness 641 00:37:13,320 --> 00:37:16,080 Speaker 1: and the blue signal, and then the other cable would 642 00:37:16,080 --> 00:37:18,440 Speaker 1: do the same thing but for the red signals, so 643 00:37:18,719 --> 00:37:21,960 Speaker 1: the difference between red and luma. And combining all of 644 00:37:22,000 --> 00:37:24,480 Speaker 1: these together you could create signals that would result in 645 00:37:24,600 --> 00:37:28,320 Speaker 1: high definition video images that could reproduce all the colors, 646 00:37:28,360 --> 00:37:31,239 Speaker 1: which is pretty neat. But once again you would need 647 00:37:31,320 --> 00:37:35,279 Speaker 1: different cables to carry audio signals. Right, and while you 648 00:37:35,320 --> 00:37:37,640 Speaker 1: could go with the old left and right r c 649 00:37:37,840 --> 00:37:42,120 Speaker 1: A connectors for stereo. There were other options. Now, I 650 00:37:42,160 --> 00:37:45,359 Speaker 1: really liked component video cables back in the day, just 651 00:37:45,440 --> 00:37:47,799 Speaker 1: to stay on that for a second. They were great 652 00:37:47,840 --> 00:37:51,920 Speaker 1: for handling analog ten A signals to televisions. That is important. 653 00:37:52,040 --> 00:37:56,560 Speaker 1: They were for analog signals, not digital. But the industry 654 00:37:56,560 --> 00:37:58,960 Speaker 1: would get behind a totally different technology for a couple 655 00:37:59,040 --> 00:38:02,680 Speaker 1: of reasons. And um I'll go into all of that 656 00:38:02,719 --> 00:38:06,920 Speaker 1: in just a minute, but quick note on audio cables. 657 00:38:06,920 --> 00:38:08,880 Speaker 1: We talked about the r c A connector types with 658 00:38:08,920 --> 00:38:11,279 Speaker 1: the white and red for left and right channels, but 659 00:38:11,360 --> 00:38:14,560 Speaker 1: obviously that isn't sufficient if you want something like surround sounds. 660 00:38:14,560 --> 00:38:17,760 Speaker 1: So to get surround sound, you might use Coacts Digital 661 00:38:18,120 --> 00:38:20,759 Speaker 1: s SLASH p d I F cables, which can be 662 00:38:20,840 --> 00:38:23,480 Speaker 1: easy to confuse with our CIA cables because they look 663 00:38:23,600 --> 00:38:26,080 Speaker 1: kind of similar. I mean, they don't have the red 664 00:38:26,120 --> 00:38:28,880 Speaker 1: and white ends the way our CIA cables do, but 665 00:38:29,160 --> 00:38:32,960 Speaker 1: they the plug part looks really similar. However, these are 666 00:38:33,000 --> 00:38:36,440 Speaker 1: capable of handling signals for surround sound systems, so you 667 00:38:36,520 --> 00:38:40,120 Speaker 1: might use these to connect your receiver to your output devices. 668 00:38:40,560 --> 00:38:44,920 Speaker 1: Then you've got an optical TS link digital cable. So 669 00:38:44,960 --> 00:38:48,200 Speaker 1: these cables provide the same sort of you know, audio 670 00:38:48,320 --> 00:38:53,680 Speaker 1: quality as coax cables do, except they use fiber optics 671 00:38:53,800 --> 00:38:57,880 Speaker 1: rather than a copper or you know, gold or whatever connection. 672 00:38:58,680 --> 00:39:01,919 Speaker 1: These are good over short distances. UH. The by short, 673 00:39:01,960 --> 00:39:05,040 Speaker 1: I mean like ten feet or less. The longer the cable, 674 00:39:05,200 --> 00:39:07,279 Speaker 1: the less performance you tend to get out of it. 675 00:39:07,280 --> 00:39:09,680 Speaker 1: It might actually take you a bit of distance to 676 00:39:09,760 --> 00:39:12,400 Speaker 1: notice the difference, but you do have a decline in 677 00:39:12,480 --> 00:39:16,680 Speaker 1: signal performance as the length of the cable increases. At 678 00:39:16,719 --> 00:39:19,480 Speaker 1: one time, they were pretty much the height of audio 679 00:39:19,600 --> 00:39:23,360 Speaker 1: cables for home theater systems, and any serious home theater 680 00:39:23,520 --> 00:39:27,880 Speaker 1: enthusiast was probably using optical digital cables to connect to 681 00:39:27,920 --> 00:39:30,880 Speaker 1: their various devices so that they could get the best 682 00:39:30,920 --> 00:39:36,280 Speaker 1: audio output. There are also then speaker wires. These typically 683 00:39:36,320 --> 00:39:39,759 Speaker 1: come in twisted pairs. Each speaker has a negative port 684 00:39:39,840 --> 00:39:42,360 Speaker 1: and a positive port. Then you want to connect the 685 00:39:42,400 --> 00:39:46,000 Speaker 1: speaker wires accordingly, with your negative lead going to the 686 00:39:46,040 --> 00:39:48,719 Speaker 1: negative port and the positive lead going to the positive port. 687 00:39:49,080 --> 00:39:52,719 Speaker 1: This is called connecting speakers in phase. UH. If you 688 00:39:52,760 --> 00:39:55,440 Speaker 1: were to connect speakers out of phase, meaning that at 689 00:39:55,520 --> 00:39:58,800 Speaker 1: least one of the speakers would be wired wrong with 690 00:39:58,880 --> 00:40:01,680 Speaker 1: the wrong leads connected of the wrong ports, then your 691 00:40:01,680 --> 00:40:05,160 Speaker 1: system can end up eliminating certain frequencies of sound. Now 692 00:40:05,200 --> 00:40:07,920 Speaker 1: that might not be blatantly obvious to you in the 693 00:40:08,000 --> 00:40:10,960 Speaker 1: moment while you're listening to stuff, but it would affect 694 00:40:11,000 --> 00:40:14,719 Speaker 1: the overall experience. So it's good to take your time 695 00:40:14,719 --> 00:40:19,600 Speaker 1: and get that right if you're using wired speakers. All right, Now, 696 00:40:19,680 --> 00:40:22,720 Speaker 1: let's talk about h d M I. So HDMI stands 697 00:40:22,760 --> 00:40:26,760 Speaker 1: for High Definition Multimedia Interface, and this type of cable 698 00:40:26,880 --> 00:40:30,680 Speaker 1: can carry both audio and video signals, so you don't 699 00:40:30,719 --> 00:40:32,799 Speaker 1: have to split them up the way you do those 700 00:40:32,800 --> 00:40:35,520 Speaker 1: previous ones I was talking about. However, there are a 701 00:40:35,560 --> 00:40:38,200 Speaker 1: few different kinds of h d m I that have 702 00:40:38,280 --> 00:40:41,760 Speaker 1: come out over the years, and they aren't all equal. See, 703 00:40:42,040 --> 00:40:45,880 Speaker 1: the HDMI standard has evolved as our video capabilities have 704 00:40:45,920 --> 00:40:50,360 Speaker 1: also evolved, and so older cables don't necessarily support the 705 00:40:50,440 --> 00:40:55,600 Speaker 1: latest technologies. So there are four different sets of specifications 706 00:40:55,600 --> 00:40:59,120 Speaker 1: for HDMI cables as defined by the h d m 707 00:40:59,120 --> 00:41:03,200 Speaker 1: I Forum Technical Working Group, and I'm sure their parties 708 00:41:03,239 --> 00:41:07,200 Speaker 1: are spectacular, and those specifications are in order. You have 709 00:41:07,320 --> 00:41:09,840 Speaker 1: standard h d m I, which can carry up to 710 00:41:10,040 --> 00:41:13,799 Speaker 1: ten a d I video resolution. With a refresh rate 711 00:41:13,840 --> 00:41:17,400 Speaker 1: of thirty hurts. If you need a refresh on refresh rates, 712 00:41:17,680 --> 00:41:19,960 Speaker 1: you can listen to the first episode in this series 713 00:41:20,040 --> 00:41:23,319 Speaker 1: that published earlier. I go into it there. Then you 714 00:41:23,360 --> 00:41:26,080 Speaker 1: have high Speed h d M I, which up the 715 00:41:26,120 --> 00:41:29,359 Speaker 1: anti to four K resolution but with a refresh rate 716 00:41:29,360 --> 00:41:33,120 Speaker 1: of just around thirty hurts. Then you've got Premium high 717 00:41:33,160 --> 00:41:35,319 Speaker 1: Speed h d M I that's up to four K 718 00:41:35,440 --> 00:41:38,719 Speaker 1: resolution with support for high dynamic Range or h d 719 00:41:38,960 --> 00:41:42,400 Speaker 1: R and a refresh rate of around sixty hurts. And 720 00:41:42,440 --> 00:41:45,360 Speaker 1: finally you've got Ultra high Speed h d M I 721 00:41:45,880 --> 00:41:48,440 Speaker 1: that has support for resolutions of up to ten K 722 00:41:49,200 --> 00:41:53,319 Speaker 1: with HDR at add twenty hurts, or you could do 723 00:41:53,440 --> 00:41:55,880 Speaker 1: four K video with a refresh rate of up to 724 00:41:55,960 --> 00:41:59,439 Speaker 1: two forty hurts. This, by the way, is another reason 725 00:41:59,440 --> 00:42:01,239 Speaker 1: why it was in portant to pay attention to what 726 00:42:01,320 --> 00:42:05,319 Speaker 1: your television can do, because again, your TV might be 727 00:42:05,400 --> 00:42:08,240 Speaker 1: capable of doing certain things like having a two forty 728 00:42:08,640 --> 00:42:12,760 Speaker 1: hurts refresh rate, but the cable you use doesn't support 729 00:42:12,840 --> 00:42:16,239 Speaker 1: that at that specific resolution, you're never going to get it. 730 00:42:16,400 --> 00:42:19,680 Speaker 1: So another important thing to keep in mind. So in 731 00:42:19,680 --> 00:42:23,840 Speaker 1: that sense, the type of cable you buy absolutely does matter. 732 00:42:24,880 --> 00:42:27,400 Speaker 1: I mean, like, if your cable is older and it 733 00:42:27,440 --> 00:42:29,799 Speaker 1: doesn't support certain formats, you're not going to be able 734 00:42:29,840 --> 00:42:32,400 Speaker 1: to experience them. So if you have a four K setup, 735 00:42:32,960 --> 00:42:36,760 Speaker 1: really you probably want a premium high speed HDMI cable 736 00:42:37,080 --> 00:42:40,360 Speaker 1: or ultra high speed. You want one of those two. 737 00:42:40,680 --> 00:42:44,799 Speaker 1: If you're looking at the HDMI version designation, like you know, 738 00:42:44,800 --> 00:42:48,120 Speaker 1: if it says HDMI one point three or one point four, 739 00:42:48,360 --> 00:42:52,040 Speaker 1: what you want is HDM two point oh to cover 740 00:42:52,200 --> 00:42:55,359 Speaker 1: your basic needs for four K. That means that it 741 00:42:55,400 --> 00:42:58,239 Speaker 1: meets the specifications for premium high speed hd M I 742 00:42:58,400 --> 00:43:01,120 Speaker 1: because they happen to fall on line. If you get 743 00:43:01,239 --> 00:43:04,040 Speaker 1: hd M I two point one cables, then you're good 744 00:43:04,040 --> 00:43:06,720 Speaker 1: for ultra high speed HDM I. You have future proofd 745 00:43:06,760 --> 00:43:10,359 Speaker 1: your home theater for the foreseeable future, or at least 746 00:43:10,520 --> 00:43:13,600 Speaker 1: the near future. I shouldn't say foreseeable because things change 747 00:43:13,640 --> 00:43:16,960 Speaker 1: so fast. But again, remember the performance you get out 748 00:43:16,960 --> 00:43:19,560 Speaker 1: of your home theater is again going to depend upon 749 00:43:19,600 --> 00:43:22,959 Speaker 1: the weakest link. I know, I keep nailing that home. 750 00:43:23,040 --> 00:43:26,279 Speaker 1: I know, I'm like a broken record, but it is 751 00:43:26,320 --> 00:43:28,879 Speaker 1: the most important thing to keep in mind because if 752 00:43:28,880 --> 00:43:31,400 Speaker 1: you trick everything else out, you're still not going to 753 00:43:31,480 --> 00:43:34,239 Speaker 1: get the experience you want if that one component is 754 00:43:34,280 --> 00:43:37,680 Speaker 1: not matching everything else. So if your TV is a 755 00:43:37,760 --> 00:43:40,520 Speaker 1: four K television, then an h d M I two 756 00:43:40,520 --> 00:43:43,719 Speaker 1: point one cable could be overkill, unless again, you just 757 00:43:43,840 --> 00:43:47,000 Speaker 1: really want that super fast refresh rate, in which case 758 00:43:47,160 --> 00:43:50,719 Speaker 1: I don't. I don't understand you, unless unless you're watching 759 00:43:50,719 --> 00:43:52,560 Speaker 1: a lot of sports. If you're watching a lot of sports, 760 00:43:52,920 --> 00:43:55,680 Speaker 1: high refresh rate I get, But in all others I 761 00:43:55,760 --> 00:43:58,640 Speaker 1: can't stand it. Otherwise, maybe that's just my own bias. 762 00:43:59,000 --> 00:44:03,000 Speaker 1: All right, So why did the industry adopt h d 763 00:44:03,200 --> 00:44:05,239 Speaker 1: M I. I mentioned that, you know, they really got 764 00:44:05,239 --> 00:44:08,319 Speaker 1: behind that and component cables kind of got left behind. Well, 765 00:44:08,400 --> 00:44:10,640 Speaker 1: part of the reason was that there was this transition 766 00:44:10,760 --> 00:44:14,920 Speaker 1: from analog to digital, and HDMI supports digital which is 767 00:44:14,920 --> 00:44:19,919 Speaker 1: all zeros and ones, and component video supported analog, which 768 00:44:19,960 --> 00:44:23,680 Speaker 1: is a continuous signal sent through a wire. These are 769 00:44:23,680 --> 00:44:27,880 Speaker 1: two different things. But another big reason is that, you know, 770 00:44:28,040 --> 00:44:30,680 Speaker 1: HDMI cable is really versatile because it can carry all 771 00:44:30,719 --> 00:44:33,640 Speaker 1: sorts of information across it, not just you know, audio 772 00:44:33,719 --> 00:44:36,960 Speaker 1: or video signals. And it's also fully capable of covering 773 00:44:37,040 --> 00:44:40,399 Speaker 1: both video and audio transmission at the same time. So 774 00:44:40,480 --> 00:44:44,040 Speaker 1: that makes it way simpler to use. Then that set 775 00:44:44,120 --> 00:44:47,440 Speaker 1: ups that requires separate cables for audio and for video. 776 00:44:47,880 --> 00:44:50,799 Speaker 1: Cable management gets way easier if you're dealing with just 777 00:44:51,000 --> 00:44:54,680 Speaker 1: h d M I. But another really big reason why 778 00:44:54,719 --> 00:44:57,200 Speaker 1: the industry got behind h d M I is because 779 00:44:57,200 --> 00:45:00,960 Speaker 1: of a different technology called h d s EP that 780 00:45:01,040 --> 00:45:05,759 Speaker 1: stands for high bandwidth Digital Content Protection. And if you 781 00:45:05,800 --> 00:45:08,080 Speaker 1: think that name makes it sound like it's DRM or 782 00:45:08,160 --> 00:45:12,920 Speaker 1: digital rights management, you win a cookie. So the purpose 783 00:45:13,000 --> 00:45:17,120 Speaker 1: of this technology is to prevent unauthorized copying of protected material, 784 00:45:17,280 --> 00:45:20,680 Speaker 1: and the technology prevents media that has been h d 785 00:45:20,880 --> 00:45:25,920 Speaker 1: c P encrypted from being played on unauthorized devices, meaning 786 00:45:26,080 --> 00:45:29,920 Speaker 1: gadgets that could potentially copy h d c P content. 787 00:45:30,400 --> 00:45:33,240 Speaker 1: So here's kind of how it works. From a really 788 00:45:33,360 --> 00:45:37,080 Speaker 1: high level. Let's say you've got two devices connected via 789 00:45:37,280 --> 00:45:40,360 Speaker 1: hd M I and device number one is a media 790 00:45:40,440 --> 00:45:43,560 Speaker 1: streaming device, and device number two is a media capture device. 791 00:45:44,080 --> 00:45:46,600 Speaker 1: Maybe it saves stuff to a hard drive or burns 792 00:45:46,640 --> 00:45:49,440 Speaker 1: it to an optical disk or whatever, doesn't really matter. 793 00:45:50,000 --> 00:45:53,479 Speaker 1: Device number one, before sending any media to device number two, 794 00:45:53,640 --> 00:45:55,880 Speaker 1: does a quick check to see if device two is 795 00:45:55,880 --> 00:46:00,160 Speaker 1: equipped to copy HDCP material and if device number one 796 00:46:00,200 --> 00:46:02,560 Speaker 1: figures out that that is the case, then you end 797 00:46:02,640 --> 00:46:04,960 Speaker 1: up getting a fail message like content could not be 798 00:46:05,080 --> 00:46:09,760 Speaker 1: displayed on this device. And it's that built in DRM 799 00:46:09,800 --> 00:46:13,400 Speaker 1: that really got the industry behind it. And for that reason, 800 00:46:13,560 --> 00:46:15,840 Speaker 1: there were a lot of home theater enthusiasts in the 801 00:46:16,000 --> 00:46:19,280 Speaker 1: h D t V era who stuck with component video 802 00:46:19,360 --> 00:46:24,279 Speaker 1: cables for as long as possible because it meant that 803 00:46:24,400 --> 00:46:27,520 Speaker 1: you weren't limited in how you were consuming your media. 804 00:46:27,680 --> 00:46:34,040 Speaker 1: There's this constant battle between the consumer and the industry 805 00:46:34,040 --> 00:46:37,760 Speaker 1: where the consumer just wants to be able to enjoy 806 00:46:38,080 --> 00:46:41,759 Speaker 1: their media on their own terms. The industry wants to 807 00:46:42,000 --> 00:46:47,239 Speaker 1: control how the media can be consumed because obviously, if 808 00:46:47,239 --> 00:46:51,800 Speaker 1: the consumer is able to replicate the media and duplicate 809 00:46:51,880 --> 00:46:56,120 Speaker 1: the media and distribute it, then that could affect the 810 00:46:56,160 --> 00:47:01,000 Speaker 1: bottom line of the industry, you know, companies. So there's 811 00:47:01,040 --> 00:47:02,640 Speaker 1: this constant back and forth and for a lot of 812 00:47:02,640 --> 00:47:05,799 Speaker 1: home theater enthusiasts, they were saying, I want to be 813 00:47:05,880 --> 00:47:09,640 Speaker 1: able to enjoy the media I have purchased in any 814 00:47:09,680 --> 00:47:14,320 Speaker 1: way I like, and I don't like having companies create 815 00:47:15,080 --> 00:47:18,440 Speaker 1: DRM that could stand as a potential barrier. And to 816 00:47:18,480 --> 00:47:26,520 Speaker 1: be fair, DRM can sometimes affect legitimate users accessing their 817 00:47:26,600 --> 00:47:29,760 Speaker 1: their material that they have purchased like that can happen. 818 00:47:29,840 --> 00:47:32,719 Speaker 1: We've seen it happen multiple times where a bad DRM 819 00:47:32,800 --> 00:47:39,759 Speaker 1: implementation actually disproportionately has a native impact on legitimate consumers, 820 00:47:39,840 --> 00:47:42,600 Speaker 1: and so then that leads to pirates figuring out ways 821 00:47:42,640 --> 00:47:47,280 Speaker 1: to circumvent DRM protection, and ultimately it doesn't do anyone 822 00:47:47,280 --> 00:47:51,560 Speaker 1: any good. It just becomes a rule that only punishes 823 00:47:51,640 --> 00:47:53,680 Speaker 1: the people who are following the rules in the first place. 824 00:47:53,920 --> 00:47:57,160 Speaker 1: So that's why a lot of home theater enthusiasts, at 825 00:47:57,239 --> 00:48:02,640 Speaker 1: least a certain subset of them, we're really reluctant to 826 00:48:02,719 --> 00:48:07,120 Speaker 1: let go of component video cables because those analog signals 827 00:48:07,480 --> 00:48:11,440 Speaker 1: could not be uh subjected to the same sort of 828 00:48:11,560 --> 00:48:15,759 Speaker 1: DRM as the digital signals that we're going through h 829 00:48:15,880 --> 00:48:19,279 Speaker 1: D M I, And that meant that a lot of 830 00:48:19,320 --> 00:48:21,680 Speaker 1: those home theater enthusiasts had to rush out there to 831 00:48:21,719 --> 00:48:27,680 Speaker 1: start buying compatible equipment because a lot of manufacturers stopped making, 832 00:48:28,680 --> 00:48:34,080 Speaker 1: you know, televisions and media devices that supported component video cables. 833 00:48:34,480 --> 00:48:36,120 Speaker 1: So that meant that you might have to run out 834 00:48:36,160 --> 00:48:38,439 Speaker 1: and buy like a DVD player and maybe a Blu 835 00:48:38,560 --> 00:48:41,920 Speaker 1: ray player because they weren't always compatible with each other. 836 00:48:42,840 --> 00:48:47,080 Speaker 1: Maybe a television and like more stuff like that before 837 00:48:47,800 --> 00:48:52,920 Speaker 1: the component video cable capability just went away, So it 838 00:48:52,960 --> 00:48:56,200 Speaker 1: was pretty wild. Also means that a lot of like 839 00:48:56,320 --> 00:48:58,840 Speaker 1: home theater enthusiasts who have been doing this for a 840 00:48:58,840 --> 00:49:04,319 Speaker 1: while have a lot of legacy systems connected. Okay, I've 841 00:49:04,320 --> 00:49:06,840 Speaker 1: got a little bit more to say about cables and 842 00:49:06,920 --> 00:49:09,759 Speaker 1: home theaters before I get to that. Let's take one 843 00:49:10,280 --> 00:49:20,560 Speaker 1: last break. So before the break, I was telling you 844 00:49:20,600 --> 00:49:23,279 Speaker 1: about h d c P and how that's a form 845 00:49:23,320 --> 00:49:25,800 Speaker 1: of DRM, and how a lot of home theater enthusiasts 846 00:49:25,800 --> 00:49:28,000 Speaker 1: were kind of reluctant to go to h d M 847 00:49:28,000 --> 00:49:32,239 Speaker 1: I cables because of that. Um that whole technology came 848 00:49:32,239 --> 00:49:35,880 Speaker 1: out of Intel. And I should add that that h 849 00:49:36,000 --> 00:49:40,080 Speaker 1: d c P encryption has long since been cracked, Like 850 00:49:40,600 --> 00:49:45,000 Speaker 1: people were able to crack that encryption years ago. Intel 851 00:49:45,040 --> 00:49:48,120 Speaker 1: says they suspect it was done through brute force. So 852 00:49:48,160 --> 00:49:51,440 Speaker 1: in other words, someone just dedicated an enormous amount of 853 00:49:51,440 --> 00:49:56,000 Speaker 1: time working through all the different possible combinations to break 854 00:49:56,000 --> 00:49:59,319 Speaker 1: that encryption and eventually hit on the right one. Now, 855 00:49:59,320 --> 00:50:03,960 Speaker 1: hardly any one bothers with circumventing HDCP at this point, 856 00:50:04,000 --> 00:50:10,480 Speaker 1: because honestly, the way we consume media has fundamentally changed 857 00:50:10,520 --> 00:50:13,200 Speaker 1: over the past decade. When h d M I was 858 00:50:13,280 --> 00:50:16,800 Speaker 1: first coming out, like twenty years ago, we were firmly 859 00:50:16,920 --> 00:50:20,560 Speaker 1: in the realm of purchasing media like DVDs and blue 860 00:50:20,640 --> 00:50:23,440 Speaker 1: rays and that kind of thing. Maybe occasionally getting an 861 00:50:23,440 --> 00:50:27,280 Speaker 1: on demand video through our our provider, like a cable 862 00:50:27,320 --> 00:50:30,880 Speaker 1: provider or satellite provider, but mostly we were buying physical 863 00:50:30,880 --> 00:50:34,000 Speaker 1: media like or we were renting them from places like 864 00:50:34,040 --> 00:50:38,560 Speaker 1: you know, Blockbuster. Do you remember Blockbuster? If you want 865 00:50:38,560 --> 00:50:42,080 Speaker 1: a reminder of Blockbuster, actually have a a series on 866 00:50:42,840 --> 00:50:45,720 Speaker 1: Blockbuster in tech stuff, So go and search the archives. 867 00:50:45,760 --> 00:50:48,160 Speaker 1: That was a fun one to do. However, these days 868 00:50:48,160 --> 00:50:51,560 Speaker 1: we get more of our content on demand via streaming 869 00:50:51,560 --> 00:50:54,960 Speaker 1: services through various providers. And that might be a cable company, 870 00:50:54,960 --> 00:50:57,520 Speaker 1: it might be a content platform, it might be you 871 00:50:57,520 --> 00:51:02,360 Speaker 1: know whatever. Now there's a whole conversation we could have 872 00:51:02,400 --> 00:51:07,080 Speaker 1: about that about how the way we access media has 873 00:51:08,120 --> 00:51:12,319 Speaker 1: really shaped the business of media. Uh, it's like the 874 00:51:12,320 --> 00:51:15,759 Speaker 1: pandemic has done that even more so, right because you 875 00:51:15,840 --> 00:51:20,280 Speaker 1: have movie theater or movie studios rather like Warner Brothers 876 00:51:20,680 --> 00:51:24,640 Speaker 1: choosing to release films both in theaters and on streaming platforms. 877 00:51:24,680 --> 00:51:28,640 Speaker 1: At the same time through the necessity of conditions brought 878 00:51:28,640 --> 00:51:33,000 Speaker 1: about by the pandemic. But that again is going to 879 00:51:33,080 --> 00:51:38,640 Speaker 1: reinforce this new model of media distribution, and that in 880 00:51:38,680 --> 00:51:40,399 Speaker 1: turn has meant that a lot of people just don't 881 00:51:40,480 --> 00:51:44,040 Speaker 1: worry about hdc P anymore because are are The way 882 00:51:44,040 --> 00:51:49,400 Speaker 1: we access stuff has changed so much. However, even with 883 00:51:49,480 --> 00:51:54,640 Speaker 1: this approach, you might occasionally have some downsides, like, for example, 884 00:51:55,160 --> 00:51:57,799 Speaker 1: and this is from my own personal experience, you could 885 00:51:57,840 --> 00:52:01,040 Speaker 1: discover something that you really like that on a streaming service, 886 00:52:01,080 --> 00:52:04,160 Speaker 1: but then eventually the service or the studio behind the 887 00:52:04,200 --> 00:52:08,760 Speaker 1: content chooses not to renew the license to stream that content, 888 00:52:08,880 --> 00:52:12,600 Speaker 1: and so the content leaves the streaming service and you 889 00:52:12,640 --> 00:52:16,719 Speaker 1: no longer have access to it. Obviously, if you purchased 890 00:52:16,760 --> 00:52:19,600 Speaker 1: a DVD or a Blu ray, you would have access 891 00:52:19,640 --> 00:52:22,279 Speaker 1: to that content for as long as the disc was 892 00:52:22,320 --> 00:52:26,120 Speaker 1: readable and you had a compatible player that could access 893 00:52:26,160 --> 00:52:28,760 Speaker 1: the media. This, by the way, is a big problem 894 00:52:28,920 --> 00:52:32,080 Speaker 1: that goes well beyond just home theaters. There's this whole 895 00:52:32,120 --> 00:52:36,239 Speaker 1: issue of the way we record stuff and the way 896 00:52:36,239 --> 00:52:41,000 Speaker 1: we access it can limit and and create a limited 897 00:52:41,080 --> 00:52:45,520 Speaker 1: shelf life for content if we don't transfer that to 898 00:52:46,040 --> 00:52:51,200 Speaker 1: newer types of media. Anyway, this happened with me with 899 00:52:51,239 --> 00:52:54,080 Speaker 1: a British sketch show called that Mitchell and web Look. 900 00:52:54,360 --> 00:52:57,480 Speaker 1: Netflix had it available once upon a time. I absolutely 901 00:52:57,520 --> 00:52:59,839 Speaker 1: loved it. It became like my go to. Even after 902 00:52:59,880 --> 00:53:04,040 Speaker 1: I seen every episode, I would go back and watch them. Eventually, however, uh, 903 00:53:04,160 --> 00:53:08,880 Speaker 1: Netflix lost its license. Like the license expired, it was 904 00:53:08,920 --> 00:53:14,000 Speaker 1: not renewed, and so the program left Netflix's US service 905 00:53:14,400 --> 00:53:17,040 Speaker 1: and I found myself unable to watch it. At least 906 00:53:17,239 --> 00:53:21,320 Speaker 1: I was unable to watch it legally. There are illegal 907 00:53:21,320 --> 00:53:22,880 Speaker 1: ways to do it, but I don't really want to 908 00:53:22,920 --> 00:53:24,759 Speaker 1: do that. I'd rather like do it in a way 909 00:53:24,760 --> 00:53:29,759 Speaker 1: that supports the show. Now, the contents region locked, and 910 00:53:30,000 --> 00:53:31,839 Speaker 1: at least the last time I checked, there was no 911 00:53:31,920 --> 00:53:34,799 Speaker 1: way to access that content in the United States. Like 912 00:53:35,480 --> 00:53:38,120 Speaker 1: the DVDs and blue rays are all region locked, so 913 00:53:38,160 --> 00:53:41,200 Speaker 1: I can't get a US region version of that. There's 914 00:53:41,239 --> 00:53:44,640 Speaker 1: no US streaming version of it as far as I know. 915 00:53:44,840 --> 00:53:46,319 Speaker 1: I mean, it may have changed since the last time 916 00:53:46,320 --> 00:53:49,160 Speaker 1: I checked, but that gets into region locking. That's another 917 00:53:49,200 --> 00:53:52,080 Speaker 1: conversation that we should probably have in the future, but 918 00:53:52,440 --> 00:53:55,719 Speaker 1: I'll leave it for now, and let's conclude with a 919 00:53:55,800 --> 00:53:59,960 Speaker 1: quick word about cable quality. I touched on this earlier, 920 00:54:00,040 --> 00:54:02,919 Speaker 1: but I thought, I think it's really good to cover 921 00:54:03,000 --> 00:54:06,960 Speaker 1: in more detail. Now I don't see it as being 922 00:54:07,680 --> 00:54:10,840 Speaker 1: as big a discussion point these days in home theater 923 00:54:10,960 --> 00:54:13,800 Speaker 1: circles as it used to be. But at one time 924 00:54:13,920 --> 00:54:18,480 Speaker 1: there were numerous companies claiming that their high tech, super 925 00:54:18,680 --> 00:54:23,720 Speaker 1: expensive cables would provide a superior experience compared to cheaper 926 00:54:23,760 --> 00:54:26,680 Speaker 1: cables on the market, and for the most part, those 927 00:54:26,719 --> 00:54:30,280 Speaker 1: claims were rubbish. There were plenty of tests that showed 928 00:54:30,320 --> 00:54:35,760 Speaker 1: that the claimed benefits were either not present or were imperceptible. 929 00:54:35,800 --> 00:54:39,759 Speaker 1: But let's talk about why cable quality matters to a 930 00:54:39,880 --> 00:54:43,960 Speaker 1: point now. Apart from whether or not the cable is 931 00:54:44,120 --> 00:54:47,799 Speaker 1: carrying the specific type of signal you want to carry, 932 00:54:47,960 --> 00:54:50,000 Speaker 1: you do have some other things that you need to 933 00:54:50,320 --> 00:54:54,239 Speaker 1: know about. So when electricity flows through a conductor, as 934 00:54:54,280 --> 00:54:57,400 Speaker 1: we mentioned with electro magnets, it creates a magnetic field. 935 00:54:58,040 --> 00:55:01,320 Speaker 1: This is one of those basic features of a electromagnetism. 936 00:55:01,360 --> 00:55:05,000 Speaker 1: So if a cable carrying electricity has poor insulation or 937 00:55:05,040 --> 00:55:09,560 Speaker 1: shielding around that cable, that can mean a couple of things. One, 938 00:55:09,880 --> 00:55:14,000 Speaker 1: the cable could cause interference in other nearby cables because 939 00:55:14,160 --> 00:55:17,760 Speaker 1: you have induction, right, if you bring a conductor close 940 00:55:17,800 --> 00:55:22,279 Speaker 1: to a fluctuating magnetic field, that will induce electricity to 941 00:55:22,400 --> 00:55:25,040 Speaker 1: flow through that conductor. So if you've got a bunch 942 00:55:25,080 --> 00:55:27,920 Speaker 1: of cables saying next to each other, then it's possible 943 00:55:27,960 --> 00:55:30,480 Speaker 1: for that you to have interference between those cables, Like 944 00:55:31,520 --> 00:55:34,520 Speaker 1: signals traveling through one cable could interfere with the signals 945 00:55:34,560 --> 00:55:39,359 Speaker 1: traveling through a neighboring cable if the shielding and insulation 946 00:55:39,800 --> 00:55:43,960 Speaker 1: is not sufficient. Same thing can happen with speaker wires. 947 00:55:44,000 --> 00:55:46,840 Speaker 1: By the way, if you've ever had, like say, really 948 00:55:46,920 --> 00:55:49,760 Speaker 1: cheap desktop speakers, I noticed this all the time with 949 00:55:49,760 --> 00:55:54,320 Speaker 1: with those because they typically had very cheap wires. Then 950 00:55:54,440 --> 00:55:56,359 Speaker 1: maybe your phone goes off and you start hearing this 951 00:55:56,400 --> 00:56:01,600 Speaker 1: weird digital chatter through your desktop speakers. That's because they're 952 00:56:01,600 --> 00:56:04,719 Speaker 1: getting interference from the radio signal that's going to your 953 00:56:04,760 --> 00:56:08,600 Speaker 1: phone and it's playing out over the speakers like they're 954 00:56:08,640 --> 00:56:11,480 Speaker 1: they're interpreting that as signals that are being sent to 955 00:56:11,520 --> 00:56:14,239 Speaker 1: the speakers themselves. So you want to make sure you 956 00:56:14,239 --> 00:56:18,440 Speaker 1: have decent shielding on your cables to avoid interference. Now, obviously, 957 00:56:18,480 --> 00:56:21,839 Speaker 1: with home theaters, you're dealing with tons of cables, even 958 00:56:21,840 --> 00:56:24,040 Speaker 1: if you're just sticking primarily with H D M I 959 00:56:24,160 --> 00:56:27,719 Speaker 1: and speaker cables, So it means you do want to 960 00:56:28,160 --> 00:56:32,359 Speaker 1: have decent cables that have good shielding to prevent any 961 00:56:32,400 --> 00:56:35,120 Speaker 1: interference between the two, Otherwise it's going to affect your 962 00:56:35,200 --> 00:56:40,440 Speaker 1: viewing or listening experience. Most modern cables have adequate shielding. 963 00:56:40,560 --> 00:56:44,680 Speaker 1: You're fine, So you're usually okay unless you're buying the 964 00:56:44,800 --> 00:56:48,600 Speaker 1: super super duper cheap cables. But you know, you definitely 965 00:56:48,640 --> 00:56:54,000 Speaker 1: don't need to go with premium, high end gold cladded cables. 966 00:56:54,040 --> 00:56:56,440 Speaker 1: You're probably not going to see any benefit from that. 967 00:56:57,239 --> 00:57:00,239 Speaker 1: There are other elements that are important with cables as well, 968 00:57:00,360 --> 00:57:05,080 Speaker 1: such as electrical resistance that could be theoretically impact your 969 00:57:05,120 --> 00:57:09,319 Speaker 1: experience and make it slightly less ideal if you're set 970 00:57:09,360 --> 00:57:12,360 Speaker 1: up means that you're using really long cables because I 971 00:57:12,400 --> 00:57:16,840 Speaker 1: don't know, maybe you've got your entertainment nexus system set 972 00:57:16,880 --> 00:57:19,440 Speaker 1: up in one room and then all the way across 973 00:57:19,480 --> 00:57:21,720 Speaker 1: the house you've got the TV. I don't know why 974 00:57:21,800 --> 00:57:23,720 Speaker 1: you would ever do that, but if you do have 975 00:57:23,800 --> 00:57:28,240 Speaker 1: to run really long cables, then electrical resistance can actually 976 00:57:28,280 --> 00:57:32,160 Speaker 1: come into play. You might need a a thicker cable 977 00:57:32,360 --> 00:57:36,520 Speaker 1: in order to have less electrical resistance over that distance. 978 00:57:37,480 --> 00:57:39,640 Speaker 1: But most of the time it's not gonna have any 979 00:57:39,720 --> 00:57:43,800 Speaker 1: perceptible impact on your experience. For most of US, standard 980 00:57:43,800 --> 00:57:46,680 Speaker 1: cables will serve just fine because the loss due to 981 00:57:46,720 --> 00:57:50,400 Speaker 1: electrical resistance will be negligible. Uh. And if you're using 982 00:57:50,400 --> 00:57:53,200 Speaker 1: optical audio cables, then you don't even have to worry 983 00:57:53,200 --> 00:57:56,280 Speaker 1: about interference because those are using fiber optics and light, 984 00:57:56,600 --> 00:58:00,280 Speaker 1: they're not using electricity and conductors. However, they do become 985 00:58:00,360 --> 00:58:03,840 Speaker 1: less efficient over longer distances. So if you are having 986 00:58:03,840 --> 00:58:07,320 Speaker 1: your TV on the opposite side of the house from 987 00:58:07,360 --> 00:58:11,160 Speaker 1: your receiver and you're running optical cables between the two, 988 00:58:11,520 --> 00:58:15,960 Speaker 1: for some reason, it would be a less than ideal experience. Um. 989 00:58:16,880 --> 00:58:20,920 Speaker 1: Bottom line, if you're buying a reputable company's cables, and 990 00:58:20,960 --> 00:58:23,560 Speaker 1: if you're you know you're making sure that whichever cables 991 00:58:23,560 --> 00:58:26,000 Speaker 1: you're buying are ones that can actually carry the signals 992 00:58:26,040 --> 00:58:29,400 Speaker 1: that the rest of your system depends upon, you should 993 00:58:29,400 --> 00:58:32,440 Speaker 1: be fine. There are purists out there who will disagree 994 00:58:32,520 --> 00:58:34,240 Speaker 1: with me. They will say, no, no, no, you need 995 00:58:34,280 --> 00:58:38,320 Speaker 1: to get this specific brand and these specific components. But 996 00:58:38,480 --> 00:58:43,160 Speaker 1: usually we're talking about performance differences that are imperceptible to 997 00:58:43,240 --> 00:58:48,080 Speaker 1: anything other than super sensitive electronic equipment. And since as 998 00:58:48,120 --> 00:58:51,120 Speaker 1: far as I know, you are not sensitive electronic equipment, 999 00:58:51,760 --> 00:58:56,680 Speaker 1: you should be fine. Okay. That concludes our epic series 1000 00:58:57,160 --> 00:59:00,640 Speaker 1: on the basics of home theater. I know clearly I 1001 00:59:00,680 --> 00:59:03,600 Speaker 1: did not go through and start naming out specific brands 1002 00:59:03,640 --> 00:59:09,520 Speaker 1: and specific models of of components and such, because I 1003 00:59:09,560 --> 00:59:11,400 Speaker 1: think a lot of that comes down to personal taste, 1004 00:59:11,440 --> 00:59:14,680 Speaker 1: like what features do you want what's already part of 1005 00:59:14,680 --> 00:59:16,960 Speaker 1: your system. You know, maybe you want to have a 1006 00:59:17,040 --> 00:59:19,880 Speaker 1: universal remote that works with stuff. You want to make 1007 00:59:19,920 --> 00:59:22,680 Speaker 1: sure that your universal remote is going to support whichever 1008 00:59:22,840 --> 00:59:25,960 Speaker 1: components you have. Otherwise there's no point in having it. 1009 00:59:25,960 --> 00:59:27,880 Speaker 1: It's just gonna be an extra remote that you'll have 1010 00:59:27,920 --> 00:59:30,160 Speaker 1: to have and in line with a ton of others. 1011 00:59:30,720 --> 00:59:34,320 Speaker 1: So because of that, and because of the very subjective 1012 00:59:34,440 --> 00:59:37,600 Speaker 1: nature of what one person thinks of as being a 1013 00:59:37,640 --> 00:59:40,880 Speaker 1: superior experience, it didn't make much sense to go into that. 1014 00:59:40,920 --> 00:59:43,080 Speaker 1: I mean, I did not talk about like the Xbox 1015 00:59:43,080 --> 00:59:46,200 Speaker 1: and the PlayStation, but those are the two leading consoles 1016 00:59:46,240 --> 00:59:49,000 Speaker 1: on the market, so that's why I talked about those. 1017 00:59:49,240 --> 00:59:52,720 Speaker 1: There are other type supports, like video ports that I 1018 00:59:52,720 --> 00:59:55,560 Speaker 1: didn't really talk about like d v I. But they 1019 00:59:55,640 --> 01:00:00,160 Speaker 1: also are not really heavily used these days unless you're 1020 01:00:00,160 --> 01:00:04,480 Speaker 1: doing something like connecting your computer to your television. Um, 1021 01:00:04,480 --> 01:00:07,080 Speaker 1: but for like the basic stuff that we think of 1022 01:00:07,280 --> 01:00:10,160 Speaker 1: for a home theater, I didn't think they were really important. 1023 01:00:10,440 --> 01:00:13,120 Speaker 1: I hope you enjoyed the series. I hope you've learned something. 1024 01:00:14,000 --> 01:00:17,520 Speaker 1: I hope you feel better about whatever purchasing choices you 1025 01:00:17,600 --> 01:00:19,880 Speaker 1: might have made so far for your home theater system, 1026 01:00:19,920 --> 01:00:23,000 Speaker 1: including you know, like, oh, should I have sprung more 1027 01:00:23,040 --> 01:00:27,680 Speaker 1: money for super fancy cables. Probably not again unless you're 1028 01:00:27,760 --> 01:00:31,600 Speaker 1: in one of those more extreme situations. And um, yeah, 1029 01:00:31,640 --> 01:00:33,560 Speaker 1: this was a fun one to do, a fun series 1030 01:00:33,600 --> 01:00:36,440 Speaker 1: to go down. And I'll probably do some more related stuff, 1031 01:00:36,440 --> 01:00:39,840 Speaker 1: like I'll talk more about uh DRM, and I'll talk 1032 01:00:39,920 --> 01:00:42,840 Speaker 1: more about the nature of how we access and consume 1033 01:00:42,960 --> 01:00:45,000 Speaker 1: media and how that has changed and how that has 1034 01:00:45,000 --> 01:00:48,120 Speaker 1: shaped technology, because that's a big part of it. But 1035 01:00:48,160 --> 01:00:50,640 Speaker 1: in the meantime, if you have any suggestions for topics 1036 01:00:50,640 --> 01:00:52,680 Speaker 1: I should cover in future episodes of tech Stuff, reach 1037 01:00:52,760 --> 01:00:54,880 Speaker 1: out to me. The best way to do that is 1038 01:00:54,920 --> 01:00:58,040 Speaker 1: over on Twitter, the handle we uses tech Stuff hs W. 1039 01:00:58,760 --> 01:01:02,520 Speaker 1: This has been a very long episode and I'll talk 1040 01:01:02,520 --> 01:01:11,120 Speaker 1: to you again really soon.
