nigel: Note that the survey is open to the Text Tracks Community Group too.
14:23:28 [nigel]
... We need to work out a working model since the expertise on WebVTT resides mainly in the TTCG even though there's a WebVTT Rec track in this group.

14:36:31 [tmichel]
Hi, sorry I am really late ...
14:37:00 [tmichel]

pal: The next step is for me to take a stab at editing the document today or tomorrow.
14:41:52 [nigel]
issue-317?
14:41:52 [trackbot]
issue-317 -- IMSC should not require frame alignment -- open
14:41:52 [trackbot]
http://www.w3.org/AudioVideo/TT/tracker/issues/317
14:43:40 [nigel]
nigel: We seem to have a debate about the relative importance of quantising to encoded frames vs allowing the presentation processor to quantise as late as possible to display frames.
14:50:20 [nigel]
nigel: has missed the debate for scribing due to technical issues

14:57:59 [nigel]
ack glenn
14:58:32 [nigel]
glenn: on the 2nd sentence of synchronisation SHALL is not the right word - it's a definition rather than a mandate.
14:59:13 [nigel]
... Under Example 1 the sentence "If ttp:frameRate is specified, then the product of ttp:frameRate and ttp:frameRateMultiplier shall be the frame rate of the related video object."
15:00:35 [nigel]
... this does not say what the behaviour of the IMSC processor is if this condition is not met - fallback rules or 'abort processing' type rules should be specified.
15:01:30 [nigel]
... point 1 again: Instead of "A media time expression M shall correspond... " it should say "A media time expression M corresponds..."
15:02:58 [nigel]
glenn: If we leave it to the implementation then the semantics are incomplete for processors. We have some generic language in TTML that may be relevant.
15:03:06 [nigel]
pal: Okay I'll reuse that wording.
15:04:03 [nigel]
pal: I'll integrate John Birch's text in 309 and change the wording for 317 too and make a stab at showing that there's flexibility in terms of the related media object.
