Speaker 1: Brought to you by the reinvented two thousand twelve camera.
Speaker 1: It's ready. Are you get in touch with technology with
Speaker 1: tech Stuff from how stuff works dot com. Hello there, everyone,
Speaker 1: and welcome to tech stuff. My name is Chris Pouette
Speaker 1: and I'm the tech editor here at how stuff works
Speaker 1: dot com. Sitting across from me, as he always does,
Speaker 1: is senior writer Jonathan Strickland. Hey there, So we uh
Speaker 1: where we're going to talk about something that you might
Speaker 1: see and not understand, at least in my case, because
Speaker 1: you know, because you see it and you don't understand
Speaker 1: it exactly. This comes This comes to us courtesy of
Speaker 1: a little listener mail and here we go. Hi. My
Speaker 1: name is James. I love how stuff Works. I was
Speaker 1: reading an article on h d M I and kind
Speaker 1: of learned how progressive scan works. But better to hear
Speaker 1: it from the experts. What can you tell me in
Speaker 1: podcast form? Well, James, um, first, as they have the
Speaker 1: whole experts. I know, maybe we're supposed to a forward
Speaker 1: this onto someone, but we'll we'll give it a shot.
Speaker 1: So progressive scan, we're talking about television's here, or monitors,
Speaker 1: computer monitors as well. Can I progressive scan most do. Um,
Speaker 1: and Uh, it's it's a technology specifically that deals with
Speaker 1: how your television generates images. Now, your old analog TVs
Speaker 1: and the the big old bulky machines that we used
Speaker 1: to watch television on us to some of us still
Speaker 1: own analog TV. Yeah, a lot of our listeners have
Speaker 1: never watched television on one of those. Can you can
Speaker 1: you think? Can you wrap your head around that? Okay?
Speaker 1: So okay, the old people in the room, Uh, we
Speaker 1: used to and sometimes still do watch television on these
Speaker 1: old analog television sets. And these TV sets use a
Speaker 1: technology called interlacing display images. So every single time you're
Speaker 1: looking at a television that's on and showing something like
Speaker 1: some sort of television program, Um, you're actually looking at
Speaker 1: thousands and thousands and thousands of tiny little dots of
Speaker 1: light that we call pixels all right now. And they
Speaker 1: come in rows, yes, rows, and columns in fact, uh,
Speaker 1: and so we we usually look at them. Uh. You
Speaker 1: can either look at them as horizontal rows or vertical columns.
Speaker 1: The idea here is that the television sort of paints
Speaker 1: this picture with light, all right. The old analog TVs
Speaker 1: used an electron gun to paint these pictures and we'll
Speaker 1: probably talk more about the electron gun, how it did this,
Speaker 1: and kind of the evolution of TVs and another future podcast. Yeah,
Speaker 1: we've got a lot of requests for that, so that
Speaker 1: that's in the that's in the works. We haven't we
Speaker 1: haven't tackled that one yet because it's a it's a
Speaker 1: little bit heavier of a topic than this, and any rate,
Speaker 1: it paints the pictures line by line, all right, and
Speaker 1: with the old interlacing technology, it wouldn't paint the entire picture,
Speaker 1: it would paint every other line, uh per per scan
Speaker 1: if you want to call it that, all right. Basically
Speaker 1: the even lines and the odd lines, and it alternates
Speaker 1: between the two and each set displays for one of
Speaker 1: a second, So thirty times a second you get all
Speaker 1: the odd lines, and thirty times a second you get
Speaker 1: all the even lines, and they're they're alternating back and forth.
Speaker 1: That gives you your sixty hurts refresh rate. Okay, but
Speaker 1: you're only getting thirty per set of lines. So that's
Speaker 1: called interlacing. It interlaces the odd lines with the even lines.
Speaker 1: Progressive scan is different, and progressive scan you get all
Speaker 1: the lines shown on each on each blasts. So instead
Speaker 1: of getting you know, half of them every thirty and
Speaker 1: the other half sorry, thirty every second for half a
Speaker 1: thirty every second for the other half, you get sixty
Speaker 1: of all of them per second with a sixty hurts
Speaker 1: refresh rate. Yes, because let's talk about sixty times per second.
Speaker 1: That's what the hurts means in this case. Um, So
Speaker 1: it's painting every line on the picture. Now, what does
Speaker 1: this mean to you as a television viewer? Well, did
Speaker 1: you want to take a stab? Well, I was going
Speaker 1: to say that damage appears more stable, yes, and it
Speaker 1: doesn't display as many artifacts, which is a very important
Speaker 1: digital bits that don't seem to you know, Yeah, they
Speaker 1: look really jagged, these little jagged exactly, there's these. If
Speaker 1: you've ever watched, um, say, a really good DVD on
Speaker 1: a on an old interlace television set, um, you might
Speaker 1: notice that there are these occasionally these little jagged uh
Speaker 1: images that show up as the as the show or
Speaker 1: the DVD plays. And it's once you notice them, it's
Speaker 1: hard not to notice them. From that point on, you
Speaker 1: start noticing them in everything, and um, it's very irritating.
Speaker 1: Progressive scan eliminates a lot of that because it does
Speaker 1: smooth out the picture. So this is why when you
Speaker 1: were first looking at h D t vs back when
Speaker 1: they were first becoming popular. Uh, you know, you had
Speaker 1: a couple of different choices. There was the seven twenty
Speaker 1: and the ten eight, which that refers to how many
Speaker 1: lines of pixels you have? Right, yes, so for for
Speaker 1: top to bottom there are seven lines or right, so,
Speaker 1: and that that changes the resolutions the top to bottom,
Speaker 1: like I think it's left right that would make sense.
Speaker 1: I'm sorry, because left right, if you have a ten
Speaker 1: a D line TV, that's the sixteen by nine resolution
Speaker 1: versus the three. Yeah, OK, so I apologize, that's all right. No,
Speaker 1: I get confused all the time about this guy's I
Speaker 1: mean I write about them all the time, and I
Speaker 1: still have to look it up because there's so many
Speaker 1: numbers that are involved here. So, but seven twenty, if
Speaker 1: you you could get like a seven twenty television, that
Speaker 1: would mean that it was a progressive scan television that
Speaker 1: had the seven or twenty lines of resolution or ten
Speaker 1: eighty I resolution, which mean I had a thousand eighty
Speaker 1: lines of resolution and that was interlaced by the way,
Speaker 1: the seven ten eighty thing. That's not really how many
Speaker 1: lines of resolution you have? How many lines of pixels?
Speaker 1: But we're gonna stick with that just because that's the
Speaker 1: what the industry standard is called. Yeah, um, so don't
Speaker 1: write in and tell me you know, actually it's not
Speaker 1: really one thousand eighty because I happen to know that. Um,
Speaker 1: but we're yeah, well, don't pause the podcast. People listen
Speaker 1: to it all the way through and then tell us
Speaker 1: how stupid we are. Um, actually we're great. So anyway,
Speaker 1: the you might think, all right, well, if this television
Speaker 1: has more lines of pixels, it must be better, be
Speaker 1: because more is better, right, well, not necessarily. Yes, you
Speaker 1: might have more pixels per on your screen. You might,
Speaker 1: and which more means you're gonna have smaller pixels usually
Speaker 1: means you have a sharper image, right, a sharper picture.
Speaker 1: That's why the definition really is all about, not the
Speaker 1: sharper image. But you're smirking at me. So, so usually
Speaker 1: more pixels does mean better. But when it comes to
Speaker 1: interlace versus progressive then you have a different argument. You're saying, well,
Speaker 1: progressive scan gives you a smoother image, especially when stuff
Speaker 1: is moving around. Um, and interlace can give you these
Speaker 1: artifacts so in that case, it might be better to
Speaker 1: get the seven twenty rather than the ten eight, especially
Speaker 1: if you're talking about smaller TVs, because these higher resolutions
Speaker 1: aren't really that noticeable on televisions that are around I
Speaker 1: don't know, thirty six inches or smaller. Three six inches
Speaker 1: is a big TV, and it really is kind of big.
Speaker 1: But when you're starting it's only when you start getting
Speaker 1: up into the fifth and sixty inch televisions that you're
Speaker 1: really start to need to worry about a ten eight resolution.
Speaker 1: And if it were ten A d I with the interlace,
Speaker 1: it would not necessarily be a better experience than if
Speaker 1: you were to get the same size. And now eventually
Speaker 1: manufacturers started to come out with ten A DP models.
Speaker 1: So these are the progressive scan uh sets that have
Speaker 1: one thousand eighty lines of resolution, and uh, those are
Speaker 1: really nice. They look really sharp. Um, again, unless you
Speaker 1: have an enormous television, it may not really make a
Speaker 1: huge difference how many lines of resolution are in there,
Speaker 1: but the the technology behind it matters a lot. Yes. Now,
Speaker 1: another thing to keep in mind is the refresh rate
Speaker 1: on your television. Now, this is this is different from
Speaker 1: whether it's progressive or interlaced. Your refresh rate is how
Speaker 1: many times your television is generating that image per second.
Speaker 1: And as we mentioned before, we were we started off
Speaker 1: talking about sixty hurts, where it was either going to
Speaker 1: be thirty times per second per set of lines with
Speaker 1: interlaced order sixty times per second for the entire picture
Speaker 1: with progressive um. But you now can find televisions with
Speaker 1: much higher refresh rates. One hurts is pretty much common
Speaker 1: now And if you go into an electronics store, yes,
Speaker 1: so that means it's regenerating that image a hundred twenty
Speaker 1: times per second. Uh, you can even find higher as
Speaker 1: refresh rates. Two hundred forty hurts is not unusual. In fact,
Speaker 1: someone in the office just recently purchased a two forty
Speaker 1: hurts television. Was not It was not I, and obviously
Speaker 1: wasn't me. Now it was someone else. I won't mention
Speaker 1: names because I didn't ask if I could, But someone
Speaker 1: else in the office for Christmas received a or went
Speaker 1: out and purchased actually a two hurts refresh rate television.
Speaker 1: Now that means that the image refreshes two hundred forty
Speaker 1: times per a second. Now, refresh rate helps smooth out
Speaker 1: images that are in that are moving very quickly. Yes.
Speaker 1: When I say moving very quickly, I mean that objects
Speaker 1: on the screen appeared to be moving. I mean, of course,
Speaker 1: it's all an illusion anyway, right, it's all the nation,
Speaker 1: But in particular, this is very important for things like sports.
Speaker 1: You know, sporting events, you've got people moving around really fast,
Speaker 1: You've got a lot of action going on. Um and
Speaker 1: with the incredible detail that you get with high definition,
Speaker 1: it can create a lot of artifacts, a lot of blurring.
Speaker 1: So you want two things. You want a television that
Speaker 1: can show a very sharp image, and you want television
Speaker 1: that can show very smooth motion. And that's where the
Speaker 1: refresh rate comes in. So that means that the three
Speaker 1: things you really need to concentrate on when you're shopping
Speaker 1: for televisions. For an HDTV are the lines of resolution.
Speaker 1: Depending on the size of the TV. If it's a
Speaker 1: really really big TV, you want the ten a D.
Speaker 1: The method of of how it's displaying the image, whether
Speaker 1: it's interlace or progressive. Progressive is better than interlace. Uh,
Speaker 1: there's no two ways around that. And then the refresh
Speaker 1: rate and refresh rate is also very important for three
Speaker 1: D technology because three D we're going back to showing
Speaker 1: two different images alternating between the two very very quickly. UM,
Speaker 1: and that requires a very fast refresh rate so that
Speaker 1: you can keep that that transition very smooth. So if
Speaker 1: you have a display that has a very high refresh rate,
Speaker 1: then it is better. It's going to be better than
Speaker 1: showing three D images. And of course here I'm talking
Speaker 1: mainly about UM ones that use polarized lenses. Uh, you
Speaker 1: have to use glasses that have a polarized lens as
Speaker 1: opposed to the old red and blue sets, because any
Speaker 1: TV can show the redden blue. I mean, that's that's
Speaker 1: a little different. You know, you don't have to have
Speaker 1: a special HD TV to do that, but if you
Speaker 1: want to do the polarization, then you're gonna need one
Speaker 1: that has a really good refresh rate. And we actually
Speaker 1: talked about the different kinds of of three D goggles
Speaker 1: or glasses, I should say, and uh, like a year ago, Yeah,
Speaker 1: like a year ago. That was almost a year nine nine, Okay,
Speaker 1: And I know this because I answered a listener mail
Speaker 1: today about three D. Do you want to talk about
Speaker 1: the the component video cable because I mean, here again,
Speaker 1: this is something we've talked about in previous podcast. But uh,
Speaker 1: you know, because of the progressive scan, the the amount
Speaker 1: of information the cables are actually handled a little differently
Speaker 1: because you don't have the typical you know, single video cable,
Speaker 1: the yellow and the red white yellow. Yeah, that's that
Speaker 1: is an important distinction progressive scan. Uh, the higher quality
Speaker 1: of device you have eating video into your television, the
Speaker 1: better the cables need to be. In the sense that
Speaker 1: the of types of cables not necessarily better within a type.
Speaker 1: We had a discussion in another podcast about whether or
Speaker 1: not expensive cables are worth it. In general, a decent
Speaker 1: cable is going to perform just as well as a
Speaker 1: very high end cable, at least for most people. I
Speaker 1: guess arguably, if you had amazingly finely tuned human senses
Speaker 1: that go beyond my own understanding, you might be able
Speaker 1: to detect the difference between high end and normal. It
Speaker 1: depends on how long the cable is and a couple,
Speaker 1: but in general, if you if the if the cable
Speaker 1: is really well made in the sense that it's really durable,
Speaker 1: then that obviously makes a difference too. I mean, you
Speaker 1: might have two cables that start out working really well
Speaker 1: and essentially are indistinguishable between the two, and then a
Speaker 1: year later, one is still performing at that level and
Speaker 1: the other is slowly kind of fallen apart because it's
Speaker 1: just a you know, not not as well made. But
Speaker 1: you don't tend to see like usually you're not going
Speaker 1: to see a jump in quality based upon the cable.
Speaker 1: But getting back to component, a component versus a composite cable.
Speaker 1: Component cable breaks out the video stream into three separate streams.
Speaker 1: So each one of those cables is carrying essentially one
Speaker 1: third of the information necessary to generate the image on
Speaker 1: your television, and it provides an incredibly sharp picture if
Speaker 1: you have the right equipment feeding the image into the TV. Yeah,
Speaker 1: it actually splits out the light and the color yes um,
Speaker 1: into the three different cables. Yeah, the cables themselves are
Speaker 1: colored red, green, and blue. So some people believe that
Speaker 1: that means that all the red information is carried on one,
Speaker 1: the green on another, and the blue on the third.
Speaker 1: It's not the case. Yeah, it's a color. It's just Yeah,
Speaker 1: it's just so that you plug the right cable into
Speaker 1: the right socket. It's all that that. That's all that
Speaker 1: really indicates. It's not an indication of what color. It
Speaker 1: tends to carry now the old, the old composite ones
Speaker 1: that like you said, it's the one yellow, it's the
Speaker 1: entire video feed, which is not going to be that
Speaker 1: that sort of high definition experience you want. You can
Speaker 1: also use h d M I, which will give you
Speaker 1: the high definition experience. I prefer the component video over
Speaker 1: the h d M I mainly because component video does
Speaker 1: not have UM DRM. Yes dr M associated with it.
Speaker 1: Digital rights management. Yes, h d M I does have
Speaker 1: digital rights management associated with it, which means that you
Speaker 1: may or may not be able to do things like
Speaker 1: make a legal copy of something for your own benefit
Speaker 1: because it's using HDMI rather than component But that also
Speaker 1: does suggest that there there's been talk that movie studios
Speaker 1: and manufacturers may stop supporting component video um entirely. They'll
Speaker 1: just stop creating devices that have component video outputs, forcing
Speaker 1: you into h d M I, which would mean, you know,
Speaker 1: that's the convenient way of getting around that whole d
Speaker 1: D r M loop. So I do not look forward
Speaker 1: to that day because eventually any electronics device that you
Speaker 1: purchase you will have to replace sometime. I mean, it's
Speaker 1: just not gonna work forever. Um. You know, either it
Speaker 1: just wears out, or the cat throws up on it,
Speaker 1: or the kid throws up on the cat and then
Speaker 1: the cat rubs up against it. It's something there's a
Speaker 1: lot of vomit involved. That's really pleasant. Thank you so
Speaker 1: much for that. Yeah, lunch is right after the podcast, folks.
Speaker 1: Um not anyway, So for Matt Frederick, Matt Frederick is
Speaker 1: our guest producer today, Ladies and gentlemen, and I hear
Speaker 1: him whimpering halfway between laughter and halfway between little sounds
Speaker 1: being disgusted. Yes, it's great. That's how we know the
Speaker 1: episode is a success when we when we discussed the
Speaker 1: producer um, So yeah, that's the that's the whole component
Speaker 1: versus composite video chord Um. Is there anything else you
Speaker 1: wanted to cover about progressive scanning? We pretty much covered
Speaker 1: the base six and and you know there's of course
Speaker 1: there's a lot behind the scenes if you're talking about
Speaker 1: technology about how does this actually work? But just for
Speaker 1: the regular consumer, the important thing to remember is that
Speaker 1: little lower case P that is going to be the
Speaker 1: indication that you're going to get the smoothest, sharpest picture.
Speaker 1: The P stands for quality. Yes, just look in a
Speaker 1: mirror and then it's a cue. Um yeah, because the
Speaker 1: the eye. Yeah, this is the confusing thing about technology
Speaker 1: is when you see a number and it's a bigger
Speaker 1: number than another number, you immediately think, oh, this one
Speaker 1: has to be better. This is one of those cases
Speaker 1: where that's not necessarily true. Well, it's easy to market
Speaker 1: because it's easy for people to understand. That's kind of
Speaker 1: going back to the whole megapixel thing with cameras. Yeah,
Speaker 1: mega hurts that, yes, that's getting of course now it's
Speaker 1: giga hurts, but yes, yes, go out and get yourself
Speaker 1: a progressive scan DVD or HD or well blue ray player.
Speaker 1: That's gonna say, h D DVD, but that's just silly.
Speaker 1: Don't go out and get one of those people that
Speaker 1: that format has been dead for two years now. Um
Speaker 1: go get a blue ray player again, an HDTV player,
Speaker 1: get a get a nice component video cord, hook them
Speaker 1: all up, enjoy that high refresh rate, watch that that
Speaker 1: high definition movie. Let your jaw hit the floor. Remember,
Speaker 1: you know, in in two thousand ten this year and
Speaker 1: we're gonna see some three D content start to come
Speaker 1: out on things like the Discovery Channel and ESPN. So
Speaker 1: you're still want one of those fast televisions, you can
Speaker 1: watch that and then just just because you have a
Speaker 1: fast television doesn't necessarily mean it's three D ready either.
Speaker 1: But we're gonna start seeing those come out hit the
Speaker 1: market this year too, so they're becoming more affordable though.
Speaker 1: That's one thing I noticed over the holiday season, you know,
Speaker 1: with all the you know, deluge of ads. Yeah, Chris
Speaker 1: pointed out earlier that a lot of the kind of
Speaker 1: the value um models of televisions are starting to come
Speaker 1: out supporting these features. You know, before it was always
Speaker 1: the leading edge companies like Sony and Panasonic. These are
Speaker 1: the ones that tend to produce the high end version
Speaker 1: of televisions, and now we're starting to see the next
Speaker 1: tier kind of produce their own h D t vs
Speaker 1: with a three D capability and other cool goodies. All right, Well,
Speaker 1: I guess that wraps up our discussion on progressive scan
Speaker 1: uh and it leads us to a little more listener mail.
Speaker 1: This listener mail comes from Gabriel, who says, hey, guys,
Speaker 1: I'm from Brazil and everyone loves your podcast over here. Wow.
Speaker 1: I wish I knew Portuguese for thank you. I'm quite
Speaker 1: curious about that in Vidio Home three D monitor. How
Speaker 1: does it work? Is it worth to worth it to
Speaker 1: buy one now? Or should I wait for the technology
Speaker 1: to develop a little more. Thanks guys, and keep it
Speaker 1: up well, Gabriel. I actually looked into this a little
Speaker 1: bit because I wasn't sure what you were referring to.
Speaker 1: In Video doesn't really make monitors. Now. They do make
Speaker 1: a software called the Nvidia Home Monitor, but that's meant
Speaker 1: to monitor your your PC. It's designed to keep tabs
Speaker 1: on what your computer is doing, how it's performing. Really like,
Speaker 1: is your CPU performing at peak performance? Do you need
Speaker 1: more memory? Do you you know? Do you need more storage?
Speaker 1: That kind of thing, And it doesn't in a three
Speaker 1: D environment because in Video has been making graphics cards
Speaker 1: and glasses that work, uh in you know, in a
Speaker 1: three D set up on your computer. Now, if you
Speaker 1: want to run three D software on your computer, what
Speaker 1: you're gonna need is you're gonna need a computer that
Speaker 1: runs at a pretty fast clip. It's gonna have to
Speaker 1: have a good graphics card like in this case we're
Speaker 1: talking about. In Nvidia makes several cards that are specifically
Speaker 1: three D capable. You're gonna need um and a pair
Speaker 1: of three D glasses. Now, and in Video's case, these
Speaker 1: are active glasses. They're not polarized. They actually have little
Speaker 1: electronic shutters in them that open and close. Self asked
Speaker 1: that you can't even see it. You can. You don't
Speaker 1: perceive that they're opening and shutting, but they are at
Speaker 1: a really fast rate. The monitor is actually displaying two
Speaker 1: different sets of images timed exactly with the way your
Speaker 1: glasses are shuttering on and off, you know, each lens alternating.
Speaker 1: So that's what creates the illusion of a three D image. Um,
Speaker 1: and the two are SYNCD up together. Right. So you've
Speaker 1: got the glasses, you've got the the computer running the
Speaker 1: with the graphics card, and you're gonna need a special monitor.
Speaker 1: And in Video actually lists the different kinds of monitors
Speaker 1: that are compatible with its system because they all have
Speaker 1: to have a specific kind of refresh rate and ord
Speaker 1: of it to work with the Nvidia graphics card. So
Speaker 1: when you get those three things together, and then of
Speaker 1: course some software that supports three D, uh, you can
Speaker 1: you can play games in three D. There's some software
Speaker 1: like the Nvidio Home Monitor, which, like I said it,
Speaker 1: all it does is really show you what your computer
Speaker 1: is doing, like how it's performing, UM, then you can
Speaker 1: use that kind of stuff. Having used the Nvidia glasses,
Speaker 1: I actually got a chance to test drive them at
Speaker 1: the Consumer Electronics Show back in two thousand nine, I
Speaker 1: can tell you I was really impressed with them. They
Speaker 1: performed really well. I played Left for Dead on UM
Speaker 1: in three D, and I was really impressed with how
Speaker 1: it performed. In fact, so much so that it is
Speaker 1: hard for me to play Left for Dead without it
Speaker 1: being in three D now because it's just not nearly
Speaker 1: as much fun. So I'd say that the technology is
Speaker 1: actually pretty well developed already. I don't know. I mean,
Speaker 1: I'm sure there will always be improvements, right, I mean,
Speaker 1: you could always wait and wait and see if something
Speaker 1: better comes out, but that's always going to be the case.
Speaker 1: You might want to wait a little bit longer because
Speaker 1: by the time this publishes, the Consumer Electronics Show for
Speaker 1: two thousand and ten will have been over, but there
Speaker 1: will be new three D monitors and three D video
Speaker 1: cards coming out, so you may just want to keep
Speaker 1: an eye out and see what the best thing is
Speaker 1: within your own price range. UM. I can tell you
Speaker 1: that it was a great experience when I played it,
Speaker 1: and more and more video game UH manufacturers, more and
Speaker 1: more UH content creators are going to support three D,
Speaker 1: So at least in the short run, it'll be it
Speaker 1: is going to be the thing. Whether it lasts, I
Speaker 1: don't know. It may just be a fad, but I
Speaker 1: can tell you it's pretty darn cool. But yes, on
Speaker 1: the on the day we're recording this, we found out that,
Speaker 1: uh that several people are coming out with full time
Speaker 1: three D channels. So I'm sure that just a few
Speaker 1: days ago we would have said, well, you know, with
Speaker 1: very little content out there, it's more likely to remain
Speaker 1: a fad, but you know, that may help push it
Speaker 1: in the other direction entirely. And one of those two
Speaker 1: content providers is ESPN and I the two the two
Speaker 1: markets I think that are going to really propel three
Speaker 1: D into the common living space will be sports and
Speaker 1: video games. Those are the two markets I think that
Speaker 1: three D is going to to first and strongest, and
Speaker 1: then eventually it will trickle down into other stuff. You'll
Speaker 1: get people who want certain three D movies, and we
Speaker 1: may eventually start to see other kinds of programs created
Speaker 1: in three D, and then who knows, maybe five years
Speaker 1: down the line, everything will be three D. Uh. I
Speaker 1: think that they really need to get past the whole
Speaker 1: you need glasses to watch this thing for that to happen. Also,
Speaker 1: if that does happen, it's really gonna leave out a
Speaker 1: lot of people who have lost vision in one eye,
Speaker 1: because you do need the use of both eyes to
Speaker 1: be able to perceive depth in all the three D
Speaker 1: systems that exist right now, except I think maybe the
Speaker 1: lenticular display, because that that does it for you. I think,
Speaker 1: I don't know. I don't know. I didn't try closing
Speaker 1: one eye when we saw you know, we actually had
Speaker 1: a chance to see one of the uh the TVs
Speaker 1: with a lenticular film over the screen, which meant that
Speaker 1: you did not have to wear glasses to see it
Speaker 1: to see the three D image, you know what. I
Speaker 1: think there's gonna be some at a consumer electronics show,
Speaker 1: which at the time of this recording, I'm about to
Speaker 1: leave to go to it, and then by the time
Speaker 1: it publishes I will have already come back. So this
Speaker 1: is time travel you guys, at the first time we've
Speaker 1: uh impersonated con travelers. Nope, and it won't be the last. Well, Gabriel,
Speaker 1: I hope that answers your question. Uh, if I didn't
