I'm helping them convert their ideas into a spec 06:39:02 nsakai has joined #websigns 06:39:03 ... although I'm not a sync specialist, but they aren't a web specialist 06:39:28 ... in a signage scenario you know better than I do so you can share your experiences/issues with me 06:39:34 ... but I believe you will benefit from this 06:40:02 ... a few figures you need to keep in mind in the context of sync 06:40:08 ... 25ms is frame accuracy 06:40:45 ... 10ms is important for audio sync 06:40:58 ... human ears can detect sync issues with audio at that threshold 06:41:08 ... unfortunately hard in browsers atm 06:41:22 ... To synchronize, you need to synchronize clocks 06:41:39 ... normally easy to achieve, one device requests other device 06:41:54 ... and do this occasionally to stay in sync 06:42:05 ... all the deployed clock sync mechanisms are different 06:42:22 ... e.g. NTP, PTP, other different standards in DTV contexts such as HbbTV 06:42:34 ... all of them start from the same simple idea but differs in implementation 06:42:42 ... it's hard to agree on how to standardize on clock sync 06:42:51 ... it's possible with a pure JS implementation 06:43:07 ... it's not accurate to the microsecond, but is within milliseconds 06:43:26 ... which is good enough 06:44:10 ... once you have a a synced clock, you distributed the updates across devices 06:44:36 ... not very network intensive, you can use WS or HTTP 06:44:54 ... hardest part is harnessing the media player 06:45:03 ... you need a way to associate your timeline with the media element 06:45:13 ... you need to tell it to use my timeline, and use my clock 06:45:18 ... this can be somewhat emulated in JS 06:45:25 ... there are some demos in the main hall 06:45:36 ... some have demos of cross device sync, which are done by some of you 06:45:55 Futomi: Yes, there were some 06:46:19 ... I developed things like ntp over websockets, but the precision isn't good enough 06:46:30 q+ 06:46:31 kaz has joined #websigns 06:46:31 ... wasn't good enough for lib sync 06:46:56 Francois: From my experience clock sync wasn't the main problem 06:47:07 Futomi: I only developed time sync 06:47:09 s/lib/lip/ 06:47:22 ... so technically it wasn't enough to get everything in place 06:47:34 ... would be interested in making it work with video playback 06:47:45 Francois: Media player harnessing is possible with js but it's hacky 06:47:50 ... wasn't actually meant to be used that way 06:48:12 Ito: We've tried this kind of mechanism 06:48:27 ... in a video context, it was good enough 06:48:44 ack i 06:48:59 Francois: From my experience it depends on the codec and player 06:49:08 ... and depends on that 06:49:34 ... I'll try a couple demos, so you get a idea of what we have done 06:49:40 ... and see if it works or not 06:50:02 ... please go to this url 06:50:07 ... http://kwz.me/MW 06:50:27 ... and when you are all connected let me know 06:51:12 ... so this uses a JS implementation from the motion corporation 06:51:21 ... it mostly follows the timing object spec 06:51:26 ... but it's a previous version 06:51:32 ... you should see a clock on your computer 06:52:02 ... this will be in sync with what you have on your screen 06:52:09 ... next is lip sync demo 06:52:19 ... if you have sound on your pc you'll hear audio 06:52:25 ... we might hear some echo 06:52:56 http://seer2.itek.norut.no/pres/w3c/secondary.html 06:53:04 ... when I use trickplay you shouldn't notice that my screen and your screen is out of sync 06:53:10 ... final one is what the timing object is about 06:53:35 ... when you want to sync stuff you can manually count and press buttons 06:53:37 ... but not good enough 06:53:56 ... but another way would be to send the command from the control server 06:54:24 ... there might be a bit of echo, as the command delivery can be delayed 06:54:48 ... there are problems with clock drifting and media element implementation differences 06:55:02 ... this makes it slightly better 06:55:41 ... it gets synced up as time passes 06:55:46 ... might take up to a minute 06:56:09 ... atm there is no implementation and is only a draft 06:57:03 ... the protocol is not specified 06:57:20 stakagi has joined #websigns 06:57:22 ... and you can implement it whatever way you prefer, e.g. by doing ntp over websockets 06:57:41 ... here is some example code 06:57:56 ... with this simple code you can get everything to play in sync 06:58:34 ... we are proposing a extension to the media element for this 06:59:11 ... this proposes to replace the media controller to have a better impl across devices 06:59:36 ... right now we can play back text tracks only with a media element 06:59:47 ... doesn't let you play without a media element 06:59:50 ... we are trying to fix this 07:00:01 ... that's it for this proposal 07:00:08 kmaru has joined #websigns 07:00:18 ... main goal is to make timing a first class citizen in web standards 07:01:27 ...

WS is just a example, you can use anything 07:05:28 Wook: What about say 10000 users? 07:05:34 Francois: It really depends 07:05:44 Wook: I'm concerned about a centralized system 07:05:57 Francois: That is up to you, the transport is neutral 07:06:05 ... and that is why we left it open ended 07:06:29 Ito: What kind of use cases are you looking for? 07:06:44 ... In digital signage, the timing reqs depend on the application and situation 07:06:53 ... in the spec there are a bunch of UCs mentioned 07:07:02 ... it's pretty broad and generic 07:07:23 ... but we want maybe up to audio (echo) sync 07:07:35 ... video wall isn't there, but should be 07:08:32 Futomi: Is the library open source? 07:08:42 Francois: Not sure. Some are, but some might not be. 07:08:48 ...
