nigel: This meeting will likely be action heavy following last week. AOB?
14:07:52 [nigel]
group: no AOB
14:08:09 [nigel]
i/nigel: This/Topic: This meeting
14:08:50 [nigel]
nigel: I haven't managed to fix up the minutes from last week - hopefully I'll be able to do that tomorrow.
14:09:05 [nigel]
... In the meantime did anyone have any changes to make based on the draft minutes?
14:09:10 [nigel]
group: No changes
14:09:23 [nigel]
nigel: In that case it's mainly a tidying job not an editorial one.
14:10:08 [nigel]
nigel: So for today we'll look at actions and I'll set aside some time for WebVTT as there's been progress there.

Topic: Action items
14:13:50 [nigel]
action-378?
14:13:50 [trackbot]
action-378 -- Pierre-Anthony Lemieux to Draft smpte request including dispositions from action-369 and backgroundcolor initial value question -- due 2015-03-05 -- OPEN
14:13:50 [trackbot]
http://www.w3.org/AudioVideo/TT/tracker/actions/378
14:14:45 [nigel]
nigel: Pierre has posted a draft for review: https://docs.google.com/document/d/1ohVIVM_lcsWooOPIsfnjHS7PnbRdON_ygydgo2V7fB4/edit
14:15:12 [nigel]
nigel: Thanks for doing that.
14:15:26 [nigel]
pal: Inline space was missing from nigel's draft. Was that just an omission.
14:15:31 [nigel]
s/on./on?
14:16:12 [nigel]
nigel: No particular reason - most likely I just didn't notice it in the original message from SMPTE.
14:16:39 [nigel]
pal: I used the latest message from SMPTE from January that was sent to public-tt rather than the
14:16:47 [nigel]
... earlier one that was sent to member-tt.
14:17:00 [nigel]
nigel: That may be the difference then.
14:18:07 [nigel]
pal: SMPTE ST428-7 specifies character rotation on any character but the TTML2 spec only allows it on
14:18:20 [nigel]
... on normally horizontal characters in vertical writing modes.
14:19:37 [nigel]
nigel: We need to make clear that SMPTE can come back to us if they have use cases that we haven't
14:19:40 [nigel]
... considered.
14:20:54 [nigel]
pal: Exactly. We could ask generally for SMPTE's responses or specifically request a request for each item.
14:21:14 [nigel]
nigel: I'd like to make it clear that we'd like a response on each item as this is very similar to a request
14:21:20 [nigel]
... for wide review type response.
14:23:27 [nigel]
pal: We shouldn't hold open the issues until SMPTE has responded.
14:23:53 [nigel]
nigel: Agreed - we should close these issues and if SMPTE or anyone else comes back with new problems
14:23:57 [nigel]
... we can open new issues.
14:24:12 [nigel]
pal: [drafts specific request]
14:26:43 [nigel]
nigel: The dispositions tool generates email text that looks like:
14:26:48 [nigel]
... "The Working Group's response to your comment is included below.
14:27:21 [nigel]
... Please review it carefully and *let us know by email at [address] if you agree with it or not
14:27:33 [nigel]
... before [date]*.
14:28:12 [nigel]
pal: I would keep it less formal and provide this as a heads-up - if SMPTE has formal comments then
14:28:19 [nigel]
... they can send them or wait until wide review.
14:28:49 [nigel]
nigel: Yes, the original comments predate the FPWD so they can't be construed as any kind of wide
14:28:56 [nigel]
... review of TTML2, more of TTML1 if anything.
14:29:53 [nigel]
nigel: Okay let's keep it less formal for now. Current wording is
14:29:55 [nigel]
... "W3C TTWG looks forward to SMPTE’s feedback on these actions, if any, and to a continued collaboration."
14:32:15 [nigel]
pal: I created the inline space text based on my understanding of ipd.
14:33:12 [nigel]
nigel: That disposition text looks good to me.
14:33:40 [nigel]
... Since Glenn has written the ipd part of TTML2 it would be good to get his go-ahead for this disposition.
14:33:57 [nigel]
Action: glenn Review Disposition text for Inline space/ipd for SMPTE
14:33:57 [trackbot]
Created ACTION-399 - Review disposition text for inline space/ipd for smpte [on Glenn Adams - due 2015-04-23].
14:34:28 [nigel]
nigel: Once that action is complete then in my view we can send this to SMPTE via Mike and close the
14:34:32 [nigel]
... outstanding issues.
14:35:11 [nigel]
nigel: I've marked action-378 as pending review.
14:35:28 [nigel]
Action-378: Action-399 created specifically for Glenn to review ipd response
14:35:28 [trackbot]
Notes added to Action-378 Draft smpte request including dispositions from action-369 and backgroundcolor initial value question.
14:37:38 [nigel]
nigel: Let's quickly step through the next actions...
14:38:01 [nigel]
nigel: On Action-390 and 391 that's in progress - I'm held up with some CSS issues right now.
14:39:16 [nigel]
courtney: I think David Singer has the dispositions for WebVTT covered but haven't talked to him about it re Action-394.
14:39:26 [nigel]
nigel: He sent a spreadsheet around earlier in the week.
14:40:21 [nigel]
nigel: There's been a bit of email conversation between me, David, Thierry and Silvia about this, offlist.
14:40:33 [nigel]
... So its safe to say progress is being made.
14:41:12 [nigel]
tmichel: The Accessibility WG said they're working on the WebVTT review and will come back with a date.
14:41:21 [nigel]
... That was the last message from Julie I think.
14:41:27 [nigel]
nigel: So we don't have a date for a date?
14:41:33 [nigel]
tmichel: I'll wait a week and then ping them again.
14:42:54 [nigel]
issue-397?
14:42:54 [trackbot]
Sorry, but issue-397 does not exist.
14:42:57 [nigel]
action-397?
14:42:57 [trackbot]
action-397 -- Pierre-Anthony Lemieux to Prepare cr2 transition version (after closing one remaining issue on imsc 1) -- due 2015-04-17 -- OPEN
14:42:57 [trackbot]
http://www.w3.org/AudioVideo/TT/tracker/actions/397
14:43:04 [nigel]
pal: On Action-397, we haven't resolved the outstanding issue with begin yet. I tried to go through
14:43:16 [nigel]
... SMIL and the best I found is that if begin is not specified then it's up to the time container. If you
14:43:34 [nigel]
... recursively follow that all the way to the top, then the begin of body is the begin of the external
14:43:42 [nigel]
... time container. Is that your understanding too?
14:43:44 [nigel]
nigel: Yes.
14:45:04 [nigel]
pal: I expect to have a resolution to that very shortly.
14:46:06 [nigel]
nigel: There is a use case for no begin time, which is when you just want the document to be
14:46:22 [nigel]
... processed as soon as possible. This might happen in live use cases. Of course you don't really know
14:46:40 [nigel]
... when that display time will start.
14:46:55 [nigel]
pal: If you have multiple consecutive documents then it's a lot easier if you specify begin times.
14:47:24 [nigel]
nigel: Right, but that does give the container freedom to resolve the begin and end of each document.
14:48:55 [nigel]
nigel: Maybe we should leave IMSC 1 as it is or add a note saying that if you have a time container
14:49:59 [nigel]
... then watch out for the unresolvable time scenario.
14:50:42 [nigel]
pal: Alternately an external time container that says 'start at 5s' should define when t=0 is.
14:51:26 [nigel]
nigel: For me, I think requiring a begin time is a bit too limiting, but highlighting the danger would be good.
14:53:50 [nigel]
pal: Okay then a note highlighting the time resolution feature of TTML and the potential danger could
14:53:54 [nigel]
... be the way to go.
14:54:11 [nigel]
nigel: You could say that time containers that only indicate 'start playing 5s in' should treat the
14:54:28 [nigel]
... resolved begin time as 'now - 5s' and step in as though that had happened.
14:55:08 [nigel]
pal: I'll draft something suggesting that an absent begin should be treated as begin at 0.
14:55:15 [nigel]
nigel: I'm happy to review that when I see the wording.
14:56:12 [nigel]
issue-382?
14:56:12 [trackbot]
issue-382 -- Require a computed non-indefinite begin time -- open
14:56:12 [trackbot]
http://www.w3.org/AudioVideo/TT/tracker/issues/382
14:56:23 [nigel]
nigel: By the way, that discussion above related to issue-382.

14:57:56 [nigel]
courtney: Not from me just now.
14:58:43 [nigel]
