It does not discuss how it is done, buffering, etc. Not real world. Mainly identifies the actors as an exercise in writing a UC. 16:15:09 Glenn - UC-2 Streamed Content Viewing. This is a bit more realistic. 16:15:58 Glenn - instead of a single URL a manifest is returned by the source to the app listing multiple sources 16:16:07 -Mark_Vickers 16:16:25 +Mark_Vickers 16:16:37 mark_vickers has joined #webtv 16:17:47 JP_Intel has joined #webtv 16:18:00 Glenn - app (sender) is in control instead of the receiver. App can control flow rate, buffers, fill rate, bit rates, etc. for optimization 16:18:55 + +33.4.89.12.aakk 16:18:59 Nilo - Is this to describe adaptive streaming? 16:19:25 Glenn - yes, one of the things introduced is adaptive streaming. Are there changes needed to the UC? 16:20:33 Nilo - can be read in several ways - same content is stored in multiple locations yet it appears to imply the files may have different representations. 16:21:54 Glenn - thinking was that so much work has been done on ABR (e.g. DADH) that we don't need to go into those details. More for exposing actors and concepts. Would it be helpful to introduce more? 16:22:23 Correction - DASH, not DADH 16:22:43 Glenn - will add more on what could be in the manifest to clarify 16:23:40 Glenn - UC-3 Identifying Streamed Content 16:24:47 Sorry, can someone indicate where these UCs can be retrieved? 16:24:57 Glenn - builds on UC-2 but adds viewer interactions. Viewer selects an asset from the list sent by sender and send request for specific content 16:25:04 + +1.858.202.aall 16:25:09 http://www.w3.org/2011/webtv/wiki/GGIE_TF/UseCases 16:25:12 Glenn - key point is to obtain an identifier 16:25:19 Thank you 16:26:02 sovang has joined #webtv 16:26:17 Glenn - identifier describes what is being played but not format, resolution, etc. Different versions will have different identifiers e.g. EIDR but no other information about the file. 16:27:29 Glenn - If 2 identifiers are equal, then the content is equal in terms of sequence of frames, frames included, etc. but no info on format properties. 16:27:54 Question - what might the differences be between 2 "equal" IDs? 16:28:46 Glenn - 2 copies of a Directors cut of a movie may be equal but in different resolutions - SD/HD. Based on how EIDR works today 16:29:25 Glenn - different compression could be used. 16:30:26 Nilo - In example of 2 Directors Cut versions, are you saying SD/HD may have same EIDR? 16:31:57 Glenn - It may have same ID but does not have to. Depends on what is registered with EIDR. Arranging to have someone from EIDR to talk to this group and answer questions. Posted link to EIDR for the group. 16:33:12 Andrew - Useful to look at EIDR as a starting point but not the only one to look at. Is is a flat or hierarchical? Does not seem to include enough info. 16:34:32 - +1.908.745.aahh 16:34:39 Glenn - their view is not hierachical in that it does not include e.g. geo info. Issue a new EIDR for different versions. But they maintain additional info for each EIDR registered that can be accessed. 16:35:45 Glenn - long ID has more information such as registrant name but much of the info is not included in the ID. 16:38:00 Glenn - described 3 ways to extract unique ID - from metadata; from imbedded watermark (audio or video); or from fingerprint 16:39:56 Glenn - 2 things to do with extracted ID - record/report for measurement/logging; Form a URI to be used with other video content sources to uniquely identify the content being viewed 16:40:58 Glenn - URI can be used to locate additional caches of the content to improve viewing experience 16:42:20 Glenn - today there is no univeral standard way to ID content, use fingerprint to ID, create URI based on an ID, etc. 16:45:56 mark_vickers has joined #webtv 16:48:32 EIDR example (click on "Relationships" tab to see hierarchy): https://ui.eidr.org/view/content?id=10.5240/6933-25C9-299D-671A-24FB-V 16:51:22 Glenn - Action Item; Create new UC where extraction is the first step 16:52:20 Action Item- ? List metadata included in the watermark by creator at creation and added downstream by the work flow 16:52:20 Error finding 'Item-'. You can review and register nicknames at . 16:53:49 Glenn - We will need to capture how to identify whether a cache has the entire file versus portions of the file at e.g. a CDN? Is anyone willing to take this UC as an action item/ 16:55:21 Question - From user perspective I search and get back a set of URIs for the content which can be used to obtain the content, switch to a new URL if there is an interuption, etc. 16:58:03 Glenn - Yes this is one of the goals of GGIE. The metadata can be used to resolve information associated with content for use throughout the workflow, user, delivery, etc. Current CDNs have a basket of "tricks" to aid in the delivery of the content. But they have very little info from the client. 16:58:37 Glenn - part of the idea here is to discuss information that the client could contribute to improve CDN performance. 16:59:52 Sorry, Glenn, but I need to drop now due to a conflcit. Will discuss offline by e-mail about introducing what you need for Content Identifier extraction. 17:00:17 Leslie - Glenn is describing how best to find the optimum version for delivery to the client/user. But I think I heard Nilo ask how does a user find the "Directors Cut" itself? 17:00:36 - +33.4.89.12.aakk 17:01:43 Nilo - seems there are several levels of resolution required - "I want a copy of the Directors Cut"; Second level of resolution includes optimizing locating the optimal flow from cache to client. 17:02:32 Glenn - so user experience is search/discovery - not network layer. What is available to watch? 17:03:19 ? - Also what is available from your service(s)/provider(s) versus what is available in general. 17:03:58 Glenn - yes. Could also include other formats, languages, etc., which may be aviable on a different service on a different device. 17:04:22 zakim, who is speaking? 17:04:33 kaz, listening for 10 seconds I heard sound from the following: +1.860.313.aaaa (57%), NiloM (4%), +1.818.777.aajj (93%) 17:04:44 Andrew - - Yes - same content might also be available from multiple providers I have access to. Would like to see all and choose myself. 17:05:11 Glenn - Anyone willing to write a rough flow of several of these concepts. Nilo, Andrew? 17:05:24 Nilo, Andrew - yes. 17:05:54 Nilo - already available using e.g. Google. 17:06:23 Nilo - I thought this is what GGIE is focused on. 17:06:45 Andrew - more technical people may be capable of using Google but many are not. 17:08:25 Glenn - The stuff from Google contains what they have discovered and put into results they think you want to see. Different from accurate/complete results tailored to the user's actual services, clients, etc. GGIE can contribute to this area of a user centric focus. 17:08:48 -alex_deacon 17:08:52 Glenn - about all content including user content, not just commercial content 17:09:05 Andrew - not describing world today, but what it could be 17:09:59 Glenn will try to populate additional UCs. Anyone can contact him to add to the UCs. 17:10:43 Glenn - next meeting: March 11, 11:00 AM ET. 17:10:43 - +1.818.777.aagg 17:10:44 -Mark_Vickers 17:10:44 -Leslie_Daigle 17:10:46 -NiloM 17:10:47 - +1.813.508.aaee 17:10:48 - +1.858.202.aall 17:10:48 - +1.818.777.aajj 17:10:50 - +8339aaff 17:10:50 -Kazuyuki 17:10:51 - +1.860.313.aaaa 17:10:52 Laters 17:11:05 ldaigle has left #webtv 17:11:21 - +1.202.429.aadd 17:11:22 WEBT_GGIE TF()11:00AM has ended 17:11:22 Attendees were +1.860.313.aaaa, +1.818.777.aabb, Leslie_Daigle, +1.913.241.aacc, Kazuyuki, +1.202.429.aadd, +1.813.508.aaee, +8339aaff, NiloM, +1.818.777.aagg, +1.908.745.aahh, 17:11:22 ... +1.415.802.aaii, Mark_Vickers, +1.818.777.aajj, alex_deacon, +33.4.89.12.aakk, +1.858.202.aall 17:16:29 jcverdie has joined #webtv 17:42:02 jcverdie has joined #webtv 18:17:19 jcverdie has joined #webtv 18:25:41 jcverdie has joined #webtv 18:57:26 jcverdie has joined #webtv 19:13:15 jcverdie has joined #webtv 23:26:23 RRSAgent has joined #webtv 23:26:23 logging to http://www.w3.org/2015/02/25-webtv-irc 23:26:55 rrsagent, draft minutes 23:26:55 I have made the request to generate http://www.w3.org/2015/02/25-webtv-minutes.html kaz
