WEBVTT - TechStuff Classic: How Periscope Works 0:00:04.400 --> 0:00:07.800 Welcome to tech stuff, a production from I heart radio. 0:00:11.720 --> 0:00:14.080 Hey there, and welcome to tech stuff. I'm your host, 0:00:14.120 --> 0:00:16.960 Jonathan Strickland. I'm an executive producer with I heart radio, 0:00:17.079 --> 0:00:19.720 and how the Tech Are you? It is a Friday. 0:00:19.800 --> 0:00:23.120 It's time for a classic episode. This episode is called 0:00:23.160 --> 0:00:26.080 how periscope works. That's how you know it's a classic, 0:00:26.360 --> 0:00:30.240 because it don't work no more. But back on August 0:00:30.280 --> 0:00:34.800 two fifteen, when this episode originally aired, it did work 0:00:35.200 --> 0:00:38.800 in a manner of fashion, and so let's dial back 0:00:38.880 --> 0:00:42.360 the clock and remember a periscope in this episode. How 0:00:42.560 --> 0:00:47.160 periscope works. So live streaming has been around for a while. 0:00:47.240 --> 0:00:49.920 It's not that new um and it's been growing in 0:00:49.960 --> 0:00:52.559 popularity for quite some time, and in some circles it's 0:00:52.640 --> 0:00:55.360 kind of old news. There were a lot of early examples, 0:00:55.400 --> 0:00:58.520 like you stream and Justin TV, which I've talked about 0:00:58.560 --> 0:01:01.680 before on tech stuff, and those allowed users the chance 0:01:01.720 --> 0:01:05.559 to broadcast using a simple setup of a computer, a microphone, 0:01:05.680 --> 0:01:07.840 a Webcam and as long as you had a good 0:01:07.880 --> 0:01:12.440 Internet connection, you were good to go. Then came twitch. 0:01:13.240 --> 0:01:15.640 Twitch is really I think we have to thank twitch 0:01:15.920 --> 0:01:21.040 for truly bringing live streaming to a new level. It 0:01:21.160 --> 0:01:23.480 started off as kind of a spinoff of Justin TV, 0:01:23.959 --> 0:01:26.800 but it went on to be so incredibly successful that 0:01:26.880 --> 0:01:31.520 it eclipsed Justin TV, got way bigger and eventually it 0:01:31.640 --> 0:01:35.560 replaced it completely. Justin TV went away, twitch stayed. Twitch 0:01:35.680 --> 0:01:38.479 is a service designed to allow gamers to stream their 0:01:38.480 --> 0:01:42.120 gaming activities live to an audience, and Gamers can use 0:01:42.200 --> 0:01:44.520 various setups to broadcast not only the game they're playing 0:01:44.520 --> 0:01:47.680 but a video of themselves as they play. It very 0:01:47.720 --> 0:01:51.200 popular service out there. At the same time there were 0:01:51.320 --> 0:01:55.320 video calling services that became popular, stuff like skype, facetime, 0:01:55.400 --> 0:01:58.000 Google hangouts, all of these making it easier to use 0:01:58.040 --> 0:02:00.120 a mobile device to do a live video call with 0:02:00.160 --> 0:02:03.720 someone else, and you could do a live broadcast hangout 0:02:03.720 --> 0:02:06.080 from Google to stream through youtube if you wanted to. 0:02:06.240 --> 0:02:09.480 But there wasn't really a streamlined way to use a 0:02:09.520 --> 0:02:13.760 mobile device to live stream content to a broad audience. 0:02:13.919 --> 0:02:17.840 It just wasn't easy. So back in two thousand thirteen 0:02:18.200 --> 0:02:21.680 there was a man named Cavin B core who was 0:02:21.720 --> 0:02:24.720 traveling to Istanbul and at the time he was the 0:02:24.760 --> 0:02:29.320 general manager and senior executive of Blackboard Mobile. He had 0:02:29.320 --> 0:02:32.120 become a member of the senior executive team after his company, 0:02:32.280 --> 0:02:36.440 terribly clever design, had been acquired and his interest up 0:02:36.440 --> 0:02:38.560 to that point had been in developing apps that made 0:02:38.560 --> 0:02:41.440 it easy for students and faculty to access and use 0:02:41.600 --> 0:02:46.600 campus data. Also, around that time, Istanbul was not a 0:02:46.760 --> 0:02:50.799 terribly safe place to be. There were these escalating political protests. 0:02:51.120 --> 0:02:53.440 They were getting violent, they were going on in the 0:02:53.480 --> 0:02:57.600 city and he wanted to know if these protests were 0:02:57.600 --> 0:03:01.000 happening in geographic regions close to where he was planning 0:03:01.040 --> 0:03:04.079 on staying when he traveled Istanbul. And he was having 0:03:04.120 --> 0:03:07.480 trouble finding that information online and news outlets. He said 0:03:07.639 --> 0:03:10.040 they moved too slowly, they were too general, they weren't 0:03:10.040 --> 0:03:12.639 specific enough. He wanted to be able to look in 0:03:12.760 --> 0:03:17.079 on very particular places within Istanbul and he used twitter 0:03:17.120 --> 0:03:20.080 to keep an eye on the situation in real time, 0:03:20.120 --> 0:03:22.320 but found himself wishing that there was some way he 0:03:22.360 --> 0:03:25.600 could view live video of the scene from there. Now 0:03:25.760 --> 0:03:29.440 you could watch recorded video after he'd been uploaded and processed, 0:03:29.560 --> 0:03:33.720 but by then it's it's pretty late. So after all 0:03:33.760 --> 0:03:38.040 of that, knowing that tons of people have smartphones, tons 0:03:38.040 --> 0:03:41.240 of people have the ability to shoot video and record video, 0:03:41.600 --> 0:03:44.480 why not have a live streaming app that combines something 0:03:44.560 --> 0:03:47.560 like a video recording program with a video calling service 0:03:47.600 --> 0:03:50.000 and make it live streaming. So he would go on 0:03:50.120 --> 0:03:53.880 to partner with a guy named Joe Bernstein to create 0:03:53.880 --> 0:03:56.520 such an APP. Now they knew that it would need 0:03:56.560 --> 0:03:59.440 to give people the opportunity to turn a phone into 0:03:59.440 --> 0:04:03.880 a camera and broadcasts that live across the Internet. They 0:04:03.920 --> 0:04:06.360 also saw the need to make the experience interactive rather 0:04:06.400 --> 0:04:10.920 than a simple stream to viewer experience. So they also 0:04:11.000 --> 0:04:13.480 knew that the experience needed to be interactive and not 0:04:13.640 --> 0:04:16.920 just a simple stream to viewer experience. So, for example, 0:04:17.040 --> 0:04:20.240 I'm streaming right now on periscope as I record this, 0:04:20.600 --> 0:04:23.479 and I can look on my app and see responses. 0:04:23.520 --> 0:04:26.120 I can see people chatting about what's happening, I can 0:04:26.160 --> 0:04:29.679 see people giving me hearts if they enjoy it, and 0:04:29.920 --> 0:04:34.039 as as people are saying it's awesome and howdy back 0:04:34.120 --> 0:04:38.360 you PS shaggy. So anyway, these two envisioned and APP 0:04:38.400 --> 0:04:41.640 that would allow people to share anything from an historic 0:04:41.680 --> 0:04:47.160 event unfolding in real time to just simple everyday activities 0:04:47.200 --> 0:04:49.719 of their daily lives. They also wanted to include features 0:04:49.720 --> 0:04:52.320 that would allow viewers to interact in some way by 0:04:52.360 --> 0:04:56.599 giving feedback or questions or just generally expressing love for 0:04:56.680 --> 0:05:00.799 what's going on. So the two founded periscope in February 0:05:01.080 --> 0:05:05.159 two thousand fourteen. And what's the first thing you do 0:05:05.279 --> 0:05:08.599 when you've found a new Internet startup company? That's right, 0:05:08.960 --> 0:05:12.000 you beg for money. They sought a round of seed 0:05:12.080 --> 0:05:15.600 investment from Angel Investors, which included Scott Belski of adobe, 0:05:15.800 --> 0:05:18.760 and they raised a few million bucks to start off. Now, 0:05:18.760 --> 0:05:22.520 their pitch included describing periscope as being similar to teleporting 0:05:22.560 --> 0:05:24.800 to a distant location to see what is going on 0:05:24.839 --> 0:05:28.000 at that exact moment, and it held a little bit 0:05:28.040 --> 0:05:32.440 more of a exciting prospect than just watching a prerecorded video. 0:05:32.520 --> 0:05:36.080 You could actually be there live while it's happening. Now, 0:05:36.080 --> 0:05:39.880 in lateen they met with Jessica Ver really, the director 0:05:39.960 --> 0:05:43.520 of corporate development and strategy for twitter, and for really 0:05:43.640 --> 0:05:48.000 was impressed and introduced them to twitter CEO Dick Costolo 0:05:48.120 --> 0:05:51.279 and Twitter Co founder Jack Dorsey, who were in turn 0:05:51.920 --> 0:05:57.200 also impressed. So this goes on. They end up having 0:05:57.240 --> 0:06:00.520 a great conversation and before long twitter make an offer 0:06:00.600 --> 0:06:04.080 to buy periscope, to acquire the company, and apparently some 0:06:04.200 --> 0:06:07.839 other entities were also interested in buying periscope, so that 0:06:07.920 --> 0:06:11.000 helped push up the price. The founder said that it 0:06:11.040 --> 0:06:15.839 was a fortuitous timing. The amount itself was not made public, 0:06:16.440 --> 0:06:18.480 but a lot of early reports said it was somewhere 0:06:18.480 --> 0:06:21.719 in between seventy five and a hundred million dollars, so 0:06:21.800 --> 0:06:25.840 not chump change. Periscope accepted twitter's offer and the company 0:06:25.920 --> 0:06:29.280 was acquired in January two thou fifteen. But twitter kept 0:06:29.279 --> 0:06:31.760 it quiet for a little bit longer for reasons I 0:06:31.800 --> 0:06:34.640 will get into in a moment. Let's just say it 0:06:34.680 --> 0:06:38.120 was a Gotcha kind of approach. See Net reported that, 0:06:38.240 --> 0:06:42.880 according to a regulatory filing, twitter had spent eighty six 0:06:42.920 --> 0:06:47.080 point six million dollars total on two acquisitions. That was 0:06:47.160 --> 0:06:50.720 periscope as acquisition number one, and a social media startup 0:06:50.720 --> 0:06:54.119 company called Niche, or niche if you prefer, and people 0:06:54.120 --> 0:06:57.280 in Niche said the purchase was about thirty million dollars 0:06:57.320 --> 0:06:59.400 for their company. So that had put periscope in around 0:06:59.440 --> 0:07:02.760 fifty six million dollars or so, so less than what 0:07:02.880 --> 0:07:06.560 some reports were saying, and honestly, there are a lot 0:07:06.600 --> 0:07:08.760 of different accounts for this and it hasn't been made 0:07:08.800 --> 0:07:12.160 completely public. So somewhere between fifty six million dollars and 0:07:12.200 --> 0:07:16.880 a hundred million dollars. That's a small margin of error right. Anyway, 0:07:17.520 --> 0:07:19.680 another live streaming APP was getting a lot of buzz 0:07:20.280 --> 0:07:26.480 right around spring of this year, called mere cat. So 0:07:27.400 --> 0:07:30.640 mere cat launched in late February, two fifteen, and it 0:07:30.760 --> 0:07:35.040 was built by a group called life on Air Incorporated. 0:07:35.800 --> 0:07:38.640 That was a team headed by Ben Ruben, and mere 0:07:38.680 --> 0:07:42.040 cat was leveraging twitter's social graphs. So you could sign 0:07:42.080 --> 0:07:45.680 into mere cat through twitter and access your followers. That way, 0:07:45.720 --> 0:07:48.800 followers could get alerts whenever you were going live on merecat. 0:07:49.120 --> 0:07:52.920 They could comment on videos, but those videos, those comments 0:07:52.960 --> 0:07:55.640 were going through twitter, so actually the comments on mercat 0:07:55.720 --> 0:07:59.880 would get published onto twitter to everybody. Not everyone was 0:08:00.040 --> 0:08:03.800 crazy about that. Merket made a particularly big splash at 0:08:03.800 --> 0:08:06.800 a little event called South by southwest, and if you're 0:08:06.800 --> 0:08:11.360 not familiar with south by southwest, it's a gigantic festival 0:08:11.400 --> 0:08:15.040 that takes place in Austin. It incorporates music and movies 0:08:15.160 --> 0:08:20.800 and what they call interactive or Internet based UH, stuffed 0:08:20.880 --> 0:08:24.040 lost startup companies end up using south by southwest is 0:08:24.080 --> 0:08:26.440 a place to either launch a new product or to 0:08:26.480 --> 0:08:30.440 announce new features to existing products. It's really a place 0:08:30.560 --> 0:08:32.600 if you aren't going to interactive. It's really a place 0:08:32.600 --> 0:08:36.520 for you to network, literally, to meet other people and 0:08:36.520 --> 0:08:40.320 convince them that your stuff is the important stuff and 0:08:40.440 --> 0:08:42.959 that people should really pay attention to you. It's if 0:08:43.000 --> 0:08:44.839 you can get people on board with your product of 0:08:44.920 --> 0:08:48.320 south by southwest that usually spills over to a lot 0:08:48.360 --> 0:08:52.400 of attention immediately following it. We'll be back soon with 0:08:52.480 --> 0:08:55.800 a little bit more about how periscope works after these messages. 0:09:05.040 --> 0:09:07.920 So mere cat raised about twelve million dollars in March, 0:09:08.080 --> 0:09:11.920 two thousand fifteen. But that same month, that's when twitter 0:09:12.280 --> 0:09:16.320 announced that it had purchased periscope and had done that 0:09:16.360 --> 0:09:19.000 back in January but kept it quiet until March, and 0:09:19.040 --> 0:09:21.400 I think a big reason for it was to steal 0:09:21.480 --> 0:09:23.679 a lot of thunder from mere cat. Twitter also did 0:09:23.720 --> 0:09:25.600 something else that some people thought was kind of dirty. 0:09:25.640 --> 0:09:31.560 Pool twitter cut the social graphic access off of mere cat. 0:09:32.400 --> 0:09:35.760 So mere cat had been depending upon twitter to use 0:09:36.240 --> 0:09:40.520 that that platform to leverage the value of their service, 0:09:40.640 --> 0:09:42.800 and now twitter saying, yeah, you know, we're going to 0:09:42.920 --> 0:09:45.079 come out with our own now so you don't get 0:09:45.120 --> 0:09:47.720 to do that, and that caused a bit of a stir. 0:09:48.240 --> 0:09:50.920 So mere cat and periscope do similar things. They both 0:09:50.920 --> 0:09:53.720 allow users to live stream from their mobile devices and 0:09:53.800 --> 0:09:57.200 both allow followers to watch and comment on them. But 0:09:57.640 --> 0:10:00.320 mere cats comments at the time all went through twitter. 0:10:00.559 --> 0:10:03.000 So some people would be reluctant to comment on a 0:10:03.080 --> 0:10:05.560 video as it's happening because they know that the entire 0:10:05.640 --> 0:10:09.679 world could see the messages. And mere cats broadcasts, at 0:10:09.720 --> 0:10:12.839 least at first, were truly live. So if you missed it, 0:10:13.240 --> 0:10:16.240 they were gone. You had no opportunity to see that stuff. 0:10:16.280 --> 0:10:19.000 You had to be there. Uh. Now you can use 0:10:19.000 --> 0:10:21.720 some additional tools to expand mercats features so that you 0:10:21.720 --> 0:10:24.640 can watch videos after they've happened, or you can comment 0:10:24.720 --> 0:10:28.160 outside of twitter. You can actually comment within mere cat itself, 0:10:28.440 --> 0:10:31.760 but at the time that was not the case. Periscope, 0:10:31.760 --> 0:10:34.080 when it launched, had a few more bells and whistles. 0:10:34.480 --> 0:10:36.800 So let's talk about what the APP looks like and 0:10:36.840 --> 0:10:39.240 what it's features are. So this is gonna be really 0:10:39.240 --> 0:10:41.560 boring to the people who are watching right now because 0:10:42.040 --> 0:10:45.040 you already know you're doing it, but for everybody else, 0:10:45.200 --> 0:10:47.120 here's what periscope is all about. Oh and by the way, 0:10:47.160 --> 0:10:50.400 tech crunch really dissed mere cat when it came out, 0:10:50.920 --> 0:10:53.880 tech crunch called it a rough shot APP built in 0:10:54.040 --> 0:10:58.800 ten days. Ouch H in fact it took about eight weeks, 0:10:58.800 --> 0:11:01.640 according to Ruben told it, but still, and it took 0:11:01.720 --> 0:11:05.880 years of developed development beyond that. So let's talk about periscope, 0:11:05.880 --> 0:11:09.000 what it looks like and the features it has. First, 0:11:09.040 --> 0:11:11.880 obviously the most important thing is you can live stream 0:11:11.880 --> 0:11:14.240 from your mobile device. You can do this to the 0:11:14.240 --> 0:11:17.000 general public, like I am doing right now. Anyone who 0:11:17.000 --> 0:11:19.680 has a link to that periscope can see what you 0:11:19.720 --> 0:11:22.679 are doing, or you can broadcast to just your followers 0:11:22.760 --> 0:11:26.240 or a subset of your followers. Viewers can watch live 0:11:26.280 --> 0:11:28.719 streams on computers, but if they do that they can 0:11:28.760 --> 0:11:31.480 only be passive viewers. There's no interactivity built into the 0:11:31.520 --> 0:11:34.280 browser version of periscope right now. If you want that 0:11:34.320 --> 0:11:37.000 interactivity you have to download the APP to your smartphone 0:11:37.320 --> 0:11:39.680 and if you watch a live stream through the periscope APP, 0:11:39.720 --> 0:11:42.280 you can interact by chatting or you tap the screen 0:11:42.320 --> 0:11:45.800 and that sends hearts. Now the hearts show up on screen. 0:11:45.880 --> 0:11:47.880 Can Anyone? Can anyone send me some hearts while I 0:11:47.920 --> 0:11:50.720 talk about this? Makes me feel better. But the hearts 0:11:50.720 --> 0:11:53.520 show up on screen and indicate that people are enjoying 0:11:53.520 --> 0:11:57.440 what they see. Hearts have also come into play in rankings, 0:11:57.480 --> 0:11:59.520 so accounts that get a lot of hearts get more 0:11:59.600 --> 0:12:03.480 visible in the periscope APP. Um when you start looking 0:12:03.559 --> 0:12:06.360 for periscopes to watch, the ones that accumulate a lot 0:12:06.360 --> 0:12:09.280 of hearts are the ones that go to the top 0:12:09.320 --> 0:12:13.880 of those lists. I am so far behind the leaders 0:12:13.880 --> 0:12:18.040 in this space that unless you just obsessively tap the 0:12:18.080 --> 0:12:21.320 screen every time I go on periscope, I won't ever 0:12:21.400 --> 0:12:25.000 show up on that list, which is okay. And unlike Merecat, 0:12:25.000 --> 0:12:27.560 the chatting doesn't go to twitter. All of that chat 0:12:27.600 --> 0:12:29.760 remains in the periscope APP, so you don't have to 0:12:29.800 --> 0:12:34.480 worry about broadcasting your questions or comments to the whole world. 0:12:34.520 --> 0:12:37.320 It's just the people who are watching, although if you 0:12:37.360 --> 0:12:41.680 do watch the video stream after it goes offline, then 0:12:41.880 --> 0:12:44.440 you still have that issue. Oh and I see that 0:12:44.480 --> 0:12:47.199 I'm stuttering a bit online, so that's fun. Once a 0:12:47.240 --> 0:12:50.640 stream is done, it stays available for twenty four hours 0:12:50.679 --> 0:12:53.040 before disappearing. So you can save a stream to your 0:12:53.040 --> 0:12:55.400 mobile device, if you have enough storage on your device 0:12:55.440 --> 0:12:57.160 to do that, and then you can upload it to 0:12:57.200 --> 0:13:01.040 it to Youtube or some other service if you wanted to. Now, 0:13:01.080 --> 0:13:03.920 if you haven't download the periscope APP, you probably aren't 0:13:03.920 --> 0:13:07.520 really aware of how it looks or or you know 0:13:07.600 --> 0:13:10.240 what it looks like rather or how it works. First 0:13:10.280 --> 0:13:12.240 you have to download the APP and install it. Obviously 0:13:12.280 --> 0:13:14.160 that's your first step, and then you have to sign 0:13:14.160 --> 0:13:16.360 into periscope. You can do that either by using your 0:13:16.360 --> 0:13:19.600 twitter handle and password or through your phone number. So 0:13:19.679 --> 0:13:22.439 if you don't have twitter, you don't. You don't have 0:13:22.520 --> 0:13:24.880 to have it to use periscope. It's just a lot 0:13:24.880 --> 0:13:27.400 of functionality will be taken out if you don't have twitter. 0:13:28.240 --> 0:13:31.360 So I'm going to concentrate on the android version because 0:13:31.640 --> 0:13:35.040 I own an android phone, so that's what I'll be 0:13:35.080 --> 0:13:37.520 talking about. But the IOS one is very similar to 0:13:37.559 --> 0:13:40.480 the same features. I just can't necessarily say the layout 0:13:40.520 --> 0:13:43.480 is exactly the same. They may be slightly different. But 0:13:43.800 --> 0:13:46.680 on the android version you've got three icons at the 0:13:46.720 --> 0:13:48.800 top left of the screen when you log in. One 0:13:48.880 --> 0:13:52.080 lists any live streams from the folks you follow on periscope. 0:13:52.800 --> 0:13:55.079 It also lists any streams from the past twenty four 0:13:55.080 --> 0:13:58.040 hours that came from those accounts, including your own. Then 0:13:58.040 --> 0:14:01.040 there's a globe icon that let that the live streams 0:14:01.080 --> 0:14:03.240 from around the world that you might be interested in, 0:14:03.440 --> 0:14:05.800 and then there's a little cluster of people icon. That 0:14:05.880 --> 0:14:08.000 list the people you follow on twitter who are also 0:14:08.000 --> 0:14:10.720 on periscope, so you can follow them on periscope as well, 0:14:11.360 --> 0:14:14.520 assuming you logged into periscope through twitter, that is. And 0:14:14.679 --> 0:14:17.720 under that list of the folks you know is a 0:14:17.800 --> 0:14:20.200 list of the most loved accounts, and those are the 0:14:20.240 --> 0:14:23.200 accounts that have accumulated the most hearts. That's the list 0:14:23.200 --> 0:14:26.920 I'm never ever going to be on. Now in the 0:14:26.960 --> 0:14:29.920 upper right corner of the people page is a link 0:14:29.960 --> 0:14:32.000 to your accounts, so you can click on that and 0:14:32.080 --> 0:14:34.600 see how you stack up, like how many people do 0:14:34.640 --> 0:14:37.640 you follow? How many people follow you? How many hearts 0:14:37.680 --> 0:14:41.040 have you accumulated as of this recording right now? This 0:14:41.120 --> 0:14:45.000 is my third periscope broadcast I've ever done and before 0:14:45.000 --> 0:14:47.520 I started recording I had around a hundred fifty followers 0:14:47.520 --> 0:14:50.640 and just over eight hundred hearts. So we'll see how 0:14:50.640 --> 0:14:53.200 many I have at the end. UH, probably not that 0:14:53.240 --> 0:14:56.920 many more, but that's that. That tells you I'm at 0:14:56.960 --> 0:15:02.400 eight hundred. The top periscopers have millions and millions of hearts, 0:15:02.960 --> 0:15:06.120 so I'm not in that league. There's also a camera 0:15:06.320 --> 0:15:08.800 icon on the screen and that initiates the live stream. 0:15:08.840 --> 0:15:11.360 So if you touch that icon it'll prompt you to 0:15:11.400 --> 0:15:13.880 make a few more choices. One thing is you can 0:15:13.880 --> 0:15:16.800 set the live stream to either public or private. A 0:15:16.880 --> 0:15:19.240 private livestream can go out to all your followers or 0:15:19.280 --> 0:15:22.440 just specific people you designate. So I could do a 0:15:22.480 --> 0:15:26.160 periscope livestream to a single person if I wanted to. UH, 0:15:26.360 --> 0:15:28.000 and it won't all show up to the public. They 0:15:28.000 --> 0:15:31.840 won't be able to view that stream, at least the 0:15:31.960 --> 0:15:34.520 video stream won't show up to the public. There was 0:15:34.560 --> 0:15:38.520 a problem in periscope's early design that involved twitter and 0:15:38.560 --> 0:15:42.160 private video titles. So if the twitter option was on 0:15:42.960 --> 0:15:46.000 and you created a private event, the title of the 0:15:46.040 --> 0:15:49.720 Stream would get tweeted out. Only the people you authorized 0:15:49.720 --> 0:15:51.960 would actually be able to watch the stream, but the 0:15:51.960 --> 0:15:56.080 title went to everyone. So if you made a title 0:15:56.200 --> 0:16:01.760 that was Oh Raunchy, or you know, you were making 0:16:01.760 --> 0:16:03.280 an in solder or something and you thought it was 0:16:03.280 --> 0:16:05.600 funny because only the people who are following you were 0:16:05.640 --> 0:16:08.120 going to see it, here's the problem. It would go 0:16:08.160 --> 0:16:10.440 out on your twitter feed if you had that activated, 0:16:10.480 --> 0:16:12.960 and everyone would see the title. They couldn't see the video, 0:16:13.000 --> 0:16:15.200 but they would know what you were talking about, so 0:16:15.280 --> 0:16:18.160 that was an issue. If your periscope account is linked 0:16:18.160 --> 0:16:19.760 to twitter, you can choose to tweet out the live 0:16:19.760 --> 0:16:22.040 stream to your followers, which I did at the beginning 0:16:22.040 --> 0:16:24.840 of this stream, and you also need to give your 0:16:24.840 --> 0:16:27.280 stream a name, so you have to title it. My 0:16:27.320 --> 0:16:30.800 first pair of SCOPE was, I think, called walking timbalt. Tibled, 0:16:30.920 --> 0:16:33.560 by the way, is the name of my puppy dog, 0:16:34.200 --> 0:16:36.320 and he is a puppy, and I think that's where 0:16:36.360 --> 0:16:39.280 seven hundred of the eight hundred hearts I have came from. 0:16:39.320 --> 0:16:41.520 So those hearts really don't belong to me. They belonged 0:16:41.560 --> 0:16:44.760 to Tibalt and he earned them, so I'm not upset. 0:16:45.960 --> 0:16:49.480 Once you're ready, you hit the start broadcasting button and 0:16:49.520 --> 0:16:52.320 you go. That's it. It's streaming. People who follow you 0:16:52.360 --> 0:16:54.640 on periscope will get a notification, if they have push 0:16:54.720 --> 0:16:57.480 notifications turned on, that you are live, and if you 0:16:57.480 --> 0:16:59.800 send a message through twitter, that will get more folks 0:16:59.800 --> 0:17:02.840 following you and watching you. Now that also means you'll 0:17:02.840 --> 0:17:06.240 get notifications when the people you follow go live as well. 0:17:06.280 --> 0:17:09.399 Those notifications will pop up on your mobile device. You 0:17:09.400 --> 0:17:11.960 can open the APP and watch and interact at that point, 0:17:12.320 --> 0:17:14.800 and periscope can use both the forward facing and rear 0:17:14.880 --> 0:17:17.320 facing cameras. On a mobile device, you can switch between 0:17:17.320 --> 0:17:19.560 the two either by double tapping on the screen or 0:17:19.600 --> 0:17:22.480 you can swipe down, which pulls up some settings and 0:17:22.520 --> 0:17:25.080 you can change it there. This lets you show people 0:17:25.200 --> 0:17:27.000 your point of view or pull it back so you 0:17:27.040 --> 0:17:30.320 can have a camera focused on your face so you 0:17:30.320 --> 0:17:33.480 can address the camera directly. Some other things to keep 0:17:33.480 --> 0:17:36.119 in mind when you're using periscope. If you have the 0:17:36.160 --> 0:17:39.240 location data on your of your phone turned on and 0:17:39.359 --> 0:17:44.040 you activate that on periscope, it will show where you 0:17:44.080 --> 0:17:47.240 are to people who are viewing the stream. This can 0:17:47.280 --> 0:17:50.000 be a privacy concern to in fact, I think originally 0:17:50.080 --> 0:17:52.840 it was set on by default. Now it's set off, 0:17:52.880 --> 0:17:56.439 at least on mine, by default. So if I want to, 0:17:56.480 --> 0:17:58.720 I can choose that and let people know where I am, 0:17:59.000 --> 0:18:00.600 but some people have pointed out this could be a 0:18:00.600 --> 0:18:03.840 privacy concern. Now, if you were to broadcast where you were, 0:18:03.960 --> 0:18:06.440 then that could be a safety issue, depending upon who 0:18:06.440 --> 0:18:10.400 you are and who's watching, especially if you're broadcasting from 0:18:11.000 --> 0:18:14.720 your home and you don't generally make that information publicly available, 0:18:15.040 --> 0:18:17.000 it could be a big issue. Some other things to 0:18:17.040 --> 0:18:19.199 keep in mind when using periscope. If you have the 0:18:19.240 --> 0:18:22.600 location data on your phone turned on and uh and 0:18:23.040 --> 0:18:26.280 you don't want people to know exactly where you are, 0:18:26.320 --> 0:18:28.159 you should switch that off. You should also keep in 0:18:28.240 --> 0:18:32.480 mind that maybe the neighbors around you don't want the 0:18:32.520 --> 0:18:36.840 world to know where they live. So just courtesy is 0:18:36.880 --> 0:18:39.320 something that you have to keep in mind. Also, there 0:18:39.400 --> 0:18:41.320 is a limit on how many people can chat on 0:18:41.400 --> 0:18:43.439 a stream. Not that I'm ever going to hit that, 0:18:43.520 --> 0:18:46.720 but once that limit is reached, anyone else trying to chat, 0:18:46.760 --> 0:18:49.600 we'll see that they can't say anything. They're blocked from chatting, 0:18:49.640 --> 0:18:52.080 and that's to make sure that the video isn't completely 0:18:52.119 --> 0:18:55.399 drowned out by chat messages for these super popular feeds, 0:18:55.400 --> 0:18:59.720 the ones that get millions of hearts in a particular stream. 0:18:59.800 --> 0:19:02.239 So mother features that are useful in periscope include the 0:19:02.280 --> 0:19:04.879 ability to block someone in chat, which is really helpful 0:19:04.920 --> 0:19:07.119 if you find someone to be particularly annoying, and you 0:19:07.160 --> 0:19:09.960 can also block someone in general so that they won't 0:19:09.960 --> 0:19:12.880 see you when you go live from that point forward. 0:19:13.320 --> 0:19:17.000 Also important if someone's trolling you. Unfortunately, there are a 0:19:17.040 --> 0:19:23.160 lot of female users who have loved the functionality of periscope, 0:19:23.160 --> 0:19:26.520 but I've received some terrible harassment, and it's a good 0:19:26.560 --> 0:19:28.919 thing that that feature exists so that they can at 0:19:29.000 --> 0:19:33.399 least address that themselves. It's unfortunate that it happens, uh, 0:19:33.440 --> 0:19:35.480 and I certainly hope that all of my tech stuff 0:19:35.520 --> 0:19:37.680 fans are the type who would never do that sort 0:19:37.680 --> 0:19:40.000 of thing. I'm pretty sure you're not. You always are 0:19:40.119 --> 0:19:42.440 awesome to me. We've got a bit more to say 0:19:42.440 --> 0:19:45.840 about how periscope works, which still feels weird to say 0:19:45.840 --> 0:19:59.639 in the present tense after these messages. So how does 0:20:00.040 --> 0:20:03.840 roscope work? We've got the what it does, but how 0:20:03.960 --> 0:20:08.000 does it work? Well, not everything has been revealed, but 0:20:08.040 --> 0:20:12.040 I imagine that it's relying upon a specific protocol. It's 0:20:12.040 --> 0:20:15.120 called H t t p live streaming, also known as 0:20:15.320 --> 0:20:18.760 H L S. it's kind of a real time communications 0:20:18.760 --> 0:20:23.240 protocol and that allows for the transmission of video streams. UH, 0:20:23.280 --> 0:20:27.679 generally speaking, it works by using a very common approach. 0:20:27.720 --> 0:20:30.760 I mean it's your basic web server approach. You've got 0:20:30.840 --> 0:20:34.840 a Web server that's designed to distribute video content. So 0:20:34.960 --> 0:20:38.000 you start broadcasting from your mobile device the data that 0:20:38.080 --> 0:20:41.120 you are creating goes out over the network, whether that's 0:20:41.119 --> 0:20:45.760 a cellular network or a Wifi Network, and then travels 0:20:45.800 --> 0:20:49.440 to the Web Server, the periscope web server. The web 0:20:49.480 --> 0:20:52.800 server then encodes the stream, probably in an h dot 0:20:52.840 --> 0:20:55.640 to six four format for the video and then some 0:20:55.720 --> 0:20:59.600 standard file format for the audio, MP three or a 0:20:59.720 --> 0:21:03.480 c three, something like that. That gets encapsulated by the 0:21:03.560 --> 0:21:07.359 impact to transport stream to be carried out to periscope viewers, 0:21:08.119 --> 0:21:10.439 and the viewers are using either the APP or the 0:21:10.440 --> 0:21:12.840 browser interface to watch the streams, and these are the 0:21:12.880 --> 0:21:18.080 clients in the basic classic server client relationship. You probably 0:21:18.160 --> 0:21:21.200 have heard that phrase a thousand times to talk about 0:21:21.200 --> 0:21:24.640 the Internet. So the client in this case would either 0:21:24.680 --> 0:21:27.919 be the browser or the APP on your smartphone, and 0:21:27.920 --> 0:21:31.000 typically the client has the resources necessary to assemble the 0:21:31.080 --> 0:21:34.720 broadcast data, those bits that are coming into the device, 0:21:35.040 --> 0:21:39.360 into a viewable flow of video. So on mobile devices 0:21:39.400 --> 0:21:41.680 that would be the APP. On your laptop, that would 0:21:41.720 --> 0:21:43.960 be a browser or desktop. I don't know why I 0:21:44.000 --> 0:21:46.080 just said Laptop. I guess they just assume people don't 0:21:46.160 --> 0:21:49.960 use desktops anymore. Sorry, Gamers, I love you. I have 0:21:50.000 --> 0:21:53.000 a desktop at home too. As the APP becomes more popular, 0:21:53.040 --> 0:21:56.440 scalability becomes an issue. So as the system gets used 0:21:56.440 --> 0:21:59.040 more heavily, it can dynamically adjust the quality of the 0:21:59.040 --> 0:22:01.560 transmitted video. So, in other words, if a lot of 0:22:01.560 --> 0:22:04.520 people are periscoping from a particular location at a time 0:22:04.520 --> 0:22:07.600 where a lot of people are are loading up the service, 0:22:08.320 --> 0:22:12.360
