15:04:05 <plh> Monica: we'll have a short meeting
15:04:49 <EBU> EBU Meeting: Matt Simpson (Red Bee Media), John Birch (Screen Subtitling), Frans de Jong (EBU), Nigel Megitt (BBC), Andreas Tai (IRT), Martin Schmalohr (IRT), Peter tho Pesch (IRT), Reinhard Möller (Zeitanker)
15:05:36 <plh> Glenn: I reviewed the text proposed by Mike, and will be able to add it this week
15:05:45 <plh> ... and will get a new draft after
15:06:56 <plh> Monica: we had a lengthy with discussion followning the issue from Netflix
15:07:00 <glenn> have received proposed text from MD to add informative note in 1.0SE that suggests an interim approach to specifying (storage) aspect ratio
15:07:26 <glenn> i expect to add this text to the 1.0SE ED this week for further review by the group
15:07:28 <plh> ... the text hasn't come to the list yet
15:08:03 <mmartin3> mmartin3 has joined #tt
15:08:10 <plh> ... this is related to issue-156, action item-148
15:08:10 <mmartin3> good morning
15:08:31 <glenn> Note:
15:08:31 <glenn> 
15:08:31 <glenn> It can be beneficial to presentation processors to signal the authorial layout intentions for aspect ratio consistent with the semantics of CEA-708-D, section 4.5 “Caption Service Metadata”, “ASPECT RATIO”. This can be implemented with external namespace metadata, such as “m708:aspectRatio” as defined in SMPTE 2052-11, Section 5.4.4.
15:09:07 <plh> Glenn: the text is clearer on which aspect ratio is referred to
15:09:37 <plh> Glenn: might need to fine tune the text
15:10:04 <plh> Monica: we want to make it clear that the text is targetted to the presentation processor rather than the author
15:10:07 <glenn> i may need to alter this text to make clear this is storage aspect ratio (SAR), and not pixel aspect ratio (PAR) or display aspect ratio (DAR)
15:10:24 <plh> q+
15:10:39 <plh> Monica: this is not normative text, just guidance
15:10:45 <plh> ... due to constraint in SE
15:11:48 <plh> Philippe: so the changes would be more substantial in 1.1?
15:12:03 <plh> Glenn: correct, we'll have to introduce new vocabulary
15:13:31 <mmartin3> Issue-201
15:13:31 <trackbot> ISSUE-201 -- How to specify aspect ratio to understand positioning that may apply for display or video. -- open
15:13:31 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/201
15:13:42 <plh> Monica: and that's a small part of issue-201
15:13:56 <plh> Glenn: keep action-148 open for now
15:15:12 <plh> Monica: let's formalize this over the week

15:17:40 <plh> Topic: EBU issues
15:18:23 <plh> andreas: we published new updates around our TTML mappings
15:18:25 <nigelmegitt> EBU-TT part 1: http://tech.ebu.ch/docs/tech/tech3350.pdf
15:19:01 <plh> Andreas: what's the status on the TTML side?
15:19:44 <plh> Monica: thank you for joining us. we made quite a bit of progress.
15:19:59 <plh> ... to advance SDP-US
15:20:05 <plh> ... the Note is now posted in the W3C site
15:20:27 <plh> http://www.w3.org/TR/ttml10-sdp-us/
15:21:08 <plh> ... we worked with Andreas to facilitate the mapping on the EBU side
15:21:36 <plh> ... Glenn, any issue we need to bring up?
15:21:39 <plh> Glenn: nope
15:21:56 <glenn> i'm open to answer any specific questions
15:22:48 <plh> Philippe: we can focus on the 1.0 SE and finish since SDP-US is behind now
15:24:03 <plh> Andreas: we're glad to continue participating
15:25:36 <nigelmegitt> nigelmegitt has joined #tt
15:26:27 <mmartin3> TOPIC: WebVTT
15:26:43 <mmartin3> plh: Finalize spec. May move to Recommendation.
15:27:00 <mmartin3> ...No timeline
15:27:13 <mmartin3> ...Apply to HTML5.
15:28:06 <mmartin3> glenn: Is the worked focused on text track API or in WebVTT to support FCC captioning requirements for rollup, painton and popup.
15:28:22 <mmartin3> plh: There is an extension to text track interface.
15:29:10 <mmartin3> glenn: Use of JavaScript - how used with content stream? Injected, interact with external web page? Don't know how to inject JavaScript? Security issues may arise.
15:29:33 <mmartin3> plh: Discuss relationship between WebVTT and TTML.
15:30:48 <mmartin3> glenn: Bug filed to WebKit to add TTML support.
15:31:05 <mmartin3> ...WebKit developer opposed because of WebVTT.
15:31:14 <mmartin3> ...IE10 has support for TTML.
15:31:34 <mmartin3> ....Input to encourage other agents to support TTML directly.
15:31:47 <mmartin3> ....View authoring rather than distribution.
15:32:07 <mmartin3> ...Misunderstanding on how TTML uses XSL-FO to describe formatting semantics.
15:32:16 <mmartin3> ....XSL-FO processor is not required.
15:33:06 <mmartin3> ...Add SE section to describe format model that uses HTML5 and CSS. Second alternative description of TTML formatting semantics.
15:33:22 <mmartin3> ...Help encourage understanding of use of TTML.
15:33:39 <mmartin3> plh: May be significant work.
15:33:52 <mmartin3> ...Publish as Working Group Note on the side.
15:34:12 <mmartin3> glenn: Will send a proposal to the list.
15:35:13 <mmartin3> ...If we map TTML to text track objects, we need to explain how to translate HTML5.
15:36:03 <mmartin3> plh: We have a Note identified in Charter.
15:36:09 <mmartin3> mmartin3: Was going to say that.
15:36:43 <mmartin3> glenn: Add informative Annex in SE.
15:37:09 <mmartin3> plh: Formatting item may not be sufficient.
15:37:37 <mmartin3> mjordan: IE has WebVTT support.
15:38:10 <mmartin3> ...Should we map to HTML5 or to WebVTT?
15:38:20 <mmartin3> glenn: Effective to translate into WebVTT.
15:38:55 <mmartin3> ...Add native support for TTML in user agents.
15:39:15 <mmartin3> ...Support TTML movie house commitments.
15:40:00 <mmartin3> mjordan: WebVTT is being rendered in HTML5 in DOM. Can we use a similar focus? Your proposal provides a translation which may be appropriate.
15:40:11 <mmartin3> glenn: Synchronic Flow Processing in TTML 1.0.
15:40:42 <mmartin3> ...Map synchronic documents to XSL-FO. Do similar description to HTML5. CSS.
15:41:26 <plh> Monica: Sean has done some mapping already, will provide a link
15:41:39 <plh> ... IE supports both WebVTT and TTML
15:42:39 <mmartin3> ...IE supports both WebVTT and TTML. TTWG has made significant progress.
15:43:28 <plh> Plh: nothing concrete at this time. if something comes up, I'll come back here
15:44:32 <mmartin3> ...andreas: Much discussion in our community.
15:44:58 <mmartin3> ....Will make proposals when our views are more concrete.
15:45:37 <mmartin3> ...Difficult to parse how to use XSL-FO.
