SDP-US Issues

Issue-19?

<trackbot> ISSUE-19 -- drop @bidi-override? -- closed

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/19

Issue-194?

<trackbot> ISSUE-194 -- root container needs better definition -- raised

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/194

mike: Explains issue - root container definition is silent in TTML 1.0. SDP-US needs to define it. Definition proposed in Issue text.

sean: Concern is whether originating TV content should account for safe area.

mike: Assume full coded video; account for safe area in authoring. DECE assumes this.

sean: Makes sense.
... Fontsize issue falls out too.
... Turn into a note to show how arrived at.

mijordan: Agree.

mmartin3: Do we add a note on safe area?

sean: Note that authors should do the safe area in positioning in authoring content.

Resolved proposal as found in the issue: http://www.w3.org/AudioVideo/TT/tracker/issues/194.

Action Glenn to implement resolution to Issue-194 as proposed http://www.w3.org/AudioVideo/TT/tracker/issues/194.

<trackbot> Created ACTION-125 - Implement resolution to Issue-194 as proposed http://www.w3.org/AudioVideo/TT/tracker/issues/194. [on Glenn Adams - due 2012-11-08].

Issue-195?

<trackbot> ISSUE-195 -- default fontSize conflcts with TTML -- raised

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/195

sean: Now we have resolved root container, we have default grid that tells us default fontSize. Add a comment how calculate font size.

mmartin3: Turn into a note. Relate R0026 as an appropriate note based on resolution for Issue-194.

Action Sean Draft text for making R0026 a Note.

<trackbot> Created ACTION-126 - Draft text for making R0026 a Note. [on Sean Hayes - due 2012-11-08].

Action Glenn to implement Issue-195 resolution based on Action-126 Note (from R0026).

<trackbot> Created ACTION-127 - Implement Issue-195 resolution based on Action-126 Note (from R0026). [on Glenn Adams - due 2012-11-08].

Resolved Issue-195 with proposal in Issue http://www.w3.org/AudioVideo/TT/tracker/issues/195 and based on Note from Sean Hayes in Action-126.

Issue-188?

<trackbot> ISSUE-188 -- Bounding SDP-US rendering complexity -- open

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/188

sean: Not ready for a presentation.

mmartin3: Suggest we discuss criteria.

sean: Compatible with CFF-TT. Limit complexity of authored document. Render upcoming subtitle in the time you have for the one you are presenting. CFF needs to go farther on the rendering model.

Double buffering is needed for a practical model.

scribe: Ratify against CFF model first.
... Separate from profile?

mmartin3: Not go in SE.

sean: Structure for SDP-US draft?

mike: Uses profile in a different way.

mmartin3: Suggested separate document with a reference paragraph in Future Needs - placeholder.

mike: Is important to profile. We could have in a second edition.
... of the profile.

sean: Want to get SDP-US published as a Note.

mmartin3: Can we take my suggestion to show in Future Needs and allow us to publish SDP-US.

sean: Reasonable approach.

mijordan:

Agree

sean: Leave open. Target to SDP-US update. Add note and won't block SDP-US issue.

<scribe> ACTION: mmartin3 Frame text for Future Needs to show we have an intent to frame a rendering model. Dolan can assist. [recorded in http://www.w3.org/2012/11/01-tt-minutes.html#action01]

<trackbot> Created ACTION-128 - Frame text for Future Needs to show we have an intent to frame a rendering model. Dolan can assist. [on Monica Martin - due 2012-11-08].

Issue-183?

<trackbot> ISSUE-183 -- semantics of using profile in a document -- open

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/183

mmartin3: Mike may update his proposal?

mike: Triggered long discussion about what profile meant.
... Withdrew text to his proposal.
...sean: Was to propose alternative text in Action-124.
... Profile applies to the document. Leave open.
... Second Edition

mike: Document conformance or behavior? Current thinking was to force decoder to replace the document. Text Dolan proposed will be withdrawn. Sean will specify decoder signal.

Glenn, are you here?

Editor Issues to Implement

mmartin3: He was to implement but I've yet to see published updates.

sean: Suggest editors' call to work through all issues.

mmartin3: Will do.

Actions Update

Action-123?

<trackbot> ACTION-123 -- Monica Martin to create updated proposa for Issue-192. -- due 2012-11-01 -- OPEN

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/123

Action-106?

<trackbot> ACTION-106 -- Mike Dolan to ask SMPTE if we can make technical requirements public. -- due 2012-09-27 -- OPEN

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/106

mike: Still open.
... Materials are fine but can't be shared out TTWG.

Close SDP-US.

sean: Get editorial actions in place. Only substantial issue is Issue-188. Get up as a published note. Unless there are any substantive issues we are in good shape to publish first edition on SDP-US as a Working Group Note?

mijordan: Agree.

sean: Agreed and move forward.

mike: Citation.

mmartin3: Will have preamble text to adopt latest version of TTML 1.0.

sean: Agreed.

mike: Readers aren't that smart.
... Put in TTML 1.0 SE as informative reference.

mmartin3: That was the intent.
... Will ensure this happens.

sean: Publish by next week Nov 8 or make a decision to do so.

mmartin3: Lots of good input on this profile. Thank you.

Adjourn.

trackbot, end meeting
