"Device-to-device content transfer" 13:36:33 olivier: I'm confused by JC's comment. 13:36:44 ... He said "yes, with all the implied limitations" 13:36:59 ... Does he means the transfer may not be allowed if there are some restrictions in place? 13:37:22 Bin_Hu: I think you're correct based on discussions we had back in May. 13:37:34 ... We talked about content protection including paid content, parental controls. 13:37:59 giuseppe: I don't see the use case and the requirement match. 13:38:10 ... There is no transfer between two devices in this use case. 13:38:23 Use Case link: http://www.w3.org/2011/webtv/wiki/Media_APIs/Use_Cases#8._.22Use_Case_Eight_.E2.80.93_Download_and_Go.22 13:38:35 Bin_Hu: In the use case no other device is involved. 13:38:50 ... After discussion with JC we added offline requirements 13:39:00 ... but the use case itself doesn't have the second device 13:39:32 Bin_Hu: Conclusion is to remove the X and ? 13:39:41 olivier: sounds like consensus. 13:39:49 ... I'm removing the comment. 13:39:59 Bin_Hu: Next is 1.16 13:40:07 ... from use case no. 6 13:40:22 ... about whether EPG also needs tuner control. 13:40:36 ... JC wonders whether EPG is just another web app. 13:40:58 Bin_Hu: Based on my reading of use case no. 6, web apps are apps that add content, not EPGs. 13:41:35 olivier: JC is right that there is overlap and there is a need for tuner control, but I don't see it as a problem that there's overlap between the use cases. They don't have exactly the same requirements. 13:42:14 giuseppe: I'll try to read these comments more by the next call. 13:42:31 Bin_Hu: If we need to merge or consolidate them we can do it later. 13:42:40 olivier: so leaving the X and ? for now. 13:42:54 Bin_Hu: Next is line 22 - req 1.20 - "Content protection" 13:43:05 ... Use cases 4, 5, 6 have question marks. 13:43:24 ... First is content sharing - seems to be obvious. 13:43:26 http://www.w3.org/2011/webtv/wiki/Media_APIs/Use_Cases#4._.22Use_Case_Four_.E2.80.93_Content_Sharing.22 13:44:22 olivier: There is a bit in use case 4 about someone launching content. There would be some content protection but I don't see it as core to the use case. 13:44:25 ... Seems more marginal than key. 13:44:28 Bin_Hu: I agree 13:45:07 ... In the use case it mentions a shared video link. That's where it comes from. 13:45:43 Mark_Vickers: When there's content protection it doesn't mean it has to be used - it means it has to be allowed for. 13:45:51 olivier: Leaving the X there. 13:45:56 Bin_Hu: Next is content search. 13:46:03 Content search UC: http://www.w3.org/2011/webtv/wiki/Media_APIs/Use_Cases#5._.22Use_Case_Five_.E2.80.93_Content_Search.22 13:46:13 Bin_Hu: Giuseppe says no. 13:46:24 s/Giuseppe/JS/ 13:46:27 s/JS/JC/ 13:46:46 olivier: In this case I'd agree with JC. It doesn't look like content protection is needed in this case. 13:46:58 kaz has joined #webtv 13:46:59 Bin_Hu: An example is a movie trailer. 13:47:22 olivier: Playing devil's advocate, for some people metadata about content is something you may want to protect. 13:47:52 ???: That kind of data is more about authentication than content protection - i.e. more crypto. 13:48:21 s/???/Cyril/ 13:48:27 Mark_Vickers: I agree. It might be good to call content protection "media content protection" which is different to data protection. 13:48:32 +1 13:48:45 Mark_Vickers: This makes it clear it doesn't apply to metadata. 13:49:04 olivier: Should we remove that part or give Sheau a chance to explain? 13:49:23 kaz has joined #webtv 13:49:35 Bin_Hu: As a group remove it, but as a courtesy give him a heads up why we think it's not relevant. He can share his thoughts with the group if necessary. 13:49:57 olivier: How about adding a comment in that cell explaining the group's consensus? 13:50:02 Bin_Hu: OK 13:50:50 Bin_Hu: Next is use case no. 7 13:50:58 kaz has joined #webtv 13:51:40 olivier: I de-resolved it. 13:52:11 Bin_Hu: JC is not sure what Sheau means. 13:52:30 olivier: Any opinion in the group about this? 13:52:49 Mark_Vickers: I think +1. There will be cases where the live TV broadcast is using content protection. 13:52:57 ... i.e. media content protection. 13:53:07 ... That's part of the pre-requisite task. 13:53:22 ... unless somebody was talking about downloads? 13:53:24 olivier: I don't think so. 13:53:47 Mark_Vickers: In that case it definitely applies. E.g. HBO is a content protected channel and has channel-bound applications. 13:54:02 olivier: So it looks like we have use cases where this does apply so yes to the X. 13:54:12 olivier: No objections. 13:54:26 olivier: I think that's all the question marks. 13:54:29 ... One more thing... 13:54:43 ... We have two use cases - 10 & 11 - for which associations have not been made. 13:54:59 ... Either we go through it quickly or we get volunteers to do it. 13:55:12 ... I prefer the latter, then we discuss any points of contention. 13:55:39 ... Any volunteers? 13:55:52 I believe there is one more X missing for 1.22 Content Playback on UC9 Download and Go 13:56:00 olivier: I'll volunteer myself 13:56:14 ACTION: olivier to fill UC/Req table for the columns of UC 10 and 11 13:56:15 Created ACTION-135 - Fill uc/req table for the columns of uc 10 and 11 [on Olivier Thereaux - due 2013-08-28]. 13:56:53 Mark_Vickers: Download and Go should be Watch and Record 13:57:09 ... Although nothing says at a later time someone can playback the content, it's mandatory and should be added. 13:57:15 olivier: I agree, that seems obvious. 13:57:22 Bin_Hu: Me too - it's implicit. 13:57:28 Mark_Vickers: We should add it to the use case. 13:57:53 ACTION: Mark to add "playback" to use case 9 13:57:53 'Mark' is an ambiguous username.

Follow that and please register. 14:00:29 -> http://www.w3.org/2013/11/TPAC/ TPAC page 14:00:54 giuseppe: We'll have a one-day meeting for this group on Tuesday to not overlap with the Web and Broadcasting group (on Monday) 14:01:57 ddavis: Please do it early because you may need a visa and a letter from Beihang University. 14:02:12 giuseppe: One other AOB is a tooling point. 14:02:28 -> https://www.w3.org/2002/09/wbs/35125/TPAC2013/?login#wbsq15 question on invitation letter 14:02:34 giuseppe: I think Google Docs works quite well so should we move the use cases over to Google Docs as well? 14:03:01 ... For me, it lowers the barrier to commenting, at least for this group which is not a long-standing group. 14:03:26 ddavis: I'd be happy as long as it doesn't require a third-party (non-W3C) account. 14:03:40 giuseppe: A third-party account is only required for the person who creates the document. 14:04:06 olivier: I'm happy with either but we should make sure we keep a backup copy. 14:04:36 +1 14:04:49 ... W3C has a strong policy - we don't want things disappearing. 14:04:55 s/.../olivier/ 14:05:08 s/olivier/olivier: / 14:05:15 ddavis: My only concern is that we avoid having too many documents in too many places. 14:05:31 giuseppe: I agree but it's better than using email attachments. 14:05:44 olivier: We can make sure the wiki points to the new version of the document. 14:06:04 +1 14:06:34 giuseppe: I'll volunteer to update the Google Docs link. 14:06:56 ... But is the wiki only editable by Team members? 14:07:07 olivier: No, it should be editable by anybody 14:07:24 Bin_Hu: In my experience I needed a W3C account to edit the wiki. 14:07:34 olivier: I think you can get a public account to do that. 14:08:06 olivier: Giuseppe, why would that concern you? Our use cases/requirements do not have strong IPR issues. 14:08:23 giuseppe: In general we're not accepting contributions from non-members. 14:08:39 giuseppe: The other solution is just to have one editor. 14:09:14 ... In this case, I could copy the document and allow someone to be the editor and others can comment on it. 14:09:23 olivier: Sounds like a good plan. 14:09:23 ... Any other business? 14:09:43 -Skip 14:09:46 -CyrilRa 14:09:47 -olivier 14:09:49 -Bin_Hu 14:09:50 olivier: OK, we are adjourned.
