15:13:16 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/360
15:14:01 <nigel> nigel: I've prepared an update to the liaison, waiting for Daniel D of W3S to approve.
15:14:15 <nigel> nigel: And I've worked through how to send this, in conjunction with the contact from ARIB.
15:14:33 <nigel> action-365?
15:14:34 <trackbot> action-365 -- Pierre-Anthony Lemieux to Review change proposal 21 in the light of closure of issue-229. -- due 2015-01-22 -- OPEN
15:14:34 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/365
15:15:04 <nigel> pal: I sent an email to the reflector about this, waiting to hear back from the Editor on this.
15:15:34 <nigel> ... So leave open for now.
15:15:50 <nigel> ... I saw that nigel had some comments on the approach to ruby, but the thread went quiet,
15:15:55 <nigel> ... so I guess you're happy with it?
15:15:58 <nigel> issue-228?
15:15:58 <trackbot> issue-228 -- Ruby text support -- closed
15:15:58 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/228
15:17:11 <nigel> nigel: This one's closed - I don't expect or need any further changes.
15:17:24 <nigel> pal: What would the alternative be - to introduce new content elements?
15:17:38 <nigel> nigel: Exactly - that's what Glenn wants to avoid.
15:18:56 <nigel> Topic: IMSC Test Suite
15:19:06 <nigel> pal: No substantial update this week - work in progress here.
15:19:26 <nigel> Topic: Issues
15:19:39 <nigel> issue-366?
15:19:39 <trackbot> issue-366 -- xml:id uniqueness needs to be broken for some uses of condition -- raised
15:19:39 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/366
15:20:49 <nigel> reopen issue-366
15:20:50 <trackbot> Re-opened issue-366.
15:22:28 <nigel> nigel: I expect this to be resolved editorially, by an edit to the style set processing, and by the
15:22:46 <nigel> ... documentation of the processing model.
15:23:08 <nigel> ... And by allowing IDREFS on region attributes.
15:24:47 <nigel> pal: So there's a way to achieve what you wanted without duplicating xml:id values?
15:24:51 <nigel> nigel: Yes, exactly.
15:25:54 <nigel> issue-224?
15:25:54 <trackbot> issue-224 -- Support text placement in 3D coordinate spaces (not zIndex compositing). -- pending review
15:25:54 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/224
15:28:39 <nigel> nigel: Glenn and I are still discussing this one.
15:28:49 <nigel> nigel: I wonder how 3D images should be handled?
15:29:18 <nigel> pal: It's the same as text - it's the same image, but rendered at different horizontal positions.
15:29:38 <nigel> ... That's for stereoscopic rendering. This approach is limited to stereoscopic rendering.
15:32:11 <nigel> issue-243?
15:32:11 <trackbot> issue-243 -- smpte:information (source material information) -- pending review
15:32:11 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/243
15:34:24 <nigel> pal: I think we've covered this before - there's an Editor's note on this, but the definition isn't
15:34:45 <nigel> ... yet synonymous with the SMPTE definitions. There's more work to do to define the syntax
15:34:49 <nigel> ... of all the named items.
15:35:42 <nigel> issue-243: Further definition of the syntax is marked as an Editor's Note - this issue depends on completion of that task.
15:35:42 <trackbot> Notes added to issue-243 smpte:information (source material information).
15:35:49 <nigel> reopen issue-243
15:35:49 <trackbot> Re-opened issue-243.
15:36:03 <nigel> issue-278?
15:36:03 <trackbot> issue-278 -- Tightening schema support for foreign vocabulary. -- pending review
15:36:03 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/278
15:38:57 <nigel> issue-289?
15:38:57 <trackbot> issue-289 -- For TTML created for overlay on top of video, signal the aspect ratio of the video the TTML was created for -- pending review
15:38:57 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/289
15:40:01 <nigel> atai: With XML Schema 1.0 I think there's probably no way to be more restrictive, especially
15:40:04 <nigel> ... for attribtues.
15:40:07 <nigel> s/tu/ut
15:40:28 <nigel> atai: That's why Glenn's TTV tool does these additional checks.
15:41:07 <nigel> nigel: Is it the general view that we do partial XSD validation and on top of that use special
15:41:09 <nigel> ... software?
15:41:32 <nigel> pal: I think that's the only way. The right way to achieve complete coverage is with reference
15:41:38 <nigel> ... code or something similar, ultimately.
15:42:03 <nigel> close issue-278
15:42:03 <trackbot> Closed issue-278.
15:42:11 <nigel> issue-289?
15:42:11 <trackbot> issue-289 -- For TTML created for overlay on top of video, signal the aspect ratio of the video the TTML was created for -- pending review
15:42:11 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/289
15:43:26 <nigel> nigel: He has a targetAspectRatio, but it's hard to tell exactly what the solution was here.
15:43:35 <nigel> pal: I think aspect ratio is somewhat in flux.
15:44:09 <nigel> nigel: I think the same goes for active format descriptor and intendedTargetBarData
15:44:50 <nigel> atai: I need to review this more.
15:46:02 <nigel> issue-364?
15:46:02 <trackbot> issue-364 -- Relax constraint between the extents of the root container and the dimensions of the related video object frame -- pending review
15:46:02 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/364
15:46:38 <nigel> pal: The CR version of IMSC 1 did not permit the renderer to scale images, forcing the creation
15:46:49 <nigel> ... of multiple versions of the same image profile document, one for each target related video
15:47:05 <nigel> ... object resolution. That makes the job of the renderer easier, but the feedback, including
15:47:22 <nigel> ... from Simon Hailes, is that scaling by renderers isn't a big issue, but having a large number of
15:47:31 <nigel> ... images is more of a problem.
15:47:58 <nigel> ... Formally we can respond to Simon with this. I'll generate some additional test cases to cover this.
15:49:06 <nigel> pal: The edit was deceptively simple: The sentence tying the tts:extent to the video object's
15:49:08 <nigel> ... size was removed.
15:50:01 <nigel> ... Also the following sentence was removed: "ittp:aspectRatio shall not be present if tts:extent is present"
15:50:29 <nigel> pal: Now you can specify aspect ratio and tts:extent.
15:50:59 <nigel> pal: And the scaling rules still apply that say that the rendering plane is as big as it can be within
15:51:02 <nigel> ... the video object.
15:51:40 <nigel> jdsmith: I'd like to have a look at the complexity of scaling images.
15:53:27 <nigel> Topic: AOB
15:53:47 <nigel> pal: I see that there's been reflector discussion with the gentleman in Croatia.
15:54:56 <nigel> nigel: I don't think there's anything more we can do there - we've provided all the help we can.
15:55:12 <nigel> ... It seems to be an implementation issue.
