15:15:24 <nigel> group: [discussion of liaison text]
15:35:49 <nigel> nigel: Just to draw this to a close, is the generic template response ok with everyone?
15:36:00 <nigel> glenn: Yes, okay with me, and could be used for DVB also as is.
15:36:23 <nigel> nigel: Ok we have consensus on the generic template.
15:39:20 <nigel> ACTION: nigel Send generic liaison to ATSC, ARIB, MPEG (via Mike), DECE, CTA, DASH-IF, DTG, HbbTV, SMPTE.
15:39:20 <trackbot> Created ACTION-487 - Send generic liaison to atsc, arib, mpeg (via mike), dece, cta, dash-if, dtg, hbbtv, smpte. [on Nigel Megitt - due 2016-11-24].
15:41:06 <nigel> ACTION: nigel Send liaison to DVB replacing first sentence from generic response with acknowledgement sentence.
15:41:06 <trackbot> Created ACTION-488 - Send liaison to dvb replacing first sentence from generic response with acknowledgement sentence. [on Nigel Megitt - due 2016-11-24].
15:41:50 <nigel> Topic: F2F
15:42:07 <nigel> Pierre: Will there be a telecon facility at the F2F?
15:42:20 <nigel> nigel: I can put one in if anyone asks - nobody has so far.
15:42:34 <nigel> Pierre: We should have a draft at the face to face meeting so I will check if that would help.
15:43:02 <nigel> Topic: IMSC
15:43:09 <nigel> close action-484
15:43:09 <trackbot> Closed action-484.
15:43:15 <nigel> nigel: Thank you for doing that drafting Pierre.
15:43:39 <tmichel> hum ... I lost you guys
15:44:14 <nigel> Action-478?
15:44:14 <trackbot> Action-478 -- Nigel Megitt to Draft a liaison to hbbtv requesting further information and proposing an option e.g. to extend imsc 1 to allow signalling of background height on span, and request timelines etc. -- due 2016-09-26 -- OPEN
15:44:14 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/478
15:44:32 <nigel> nigel: The agreed liaison text in principle covers this action but maybe we should try to
15:44:48 <nigel> ... add a paragraph as previously discussed asking about background height on span. I will
15:44:55 <nigel> ... draft an additional paragraph and send for review.
15:45:21 <nigel> Topic: TTML1 & TTML2 issues, actions, PRs, editorial actions etc
15:45:54 <nigel> nigel: First thing to note is we have a new WD published with today's date on it.
15:46:04 <tmichel> I am back
15:46:08 <nigel> -> https://www.w3.org/TR/2016/WD-ttml2-20161117/
15:48:26 <nigel> tmichel: There was a bit of confusion about the new pub rules checker which is very strict,
15:48:41 <nigel> ... and does not let anything through that is not an exact match.
15:50:06 <nigel> nigel: Thank you Thierry and Glenn for getting that out.
15:50:33 <nigel> tmichel: Should I send this to the horizontal reviewers.
15:51:22 <nigel> nigel: My view is send this now since there is no restriction asking us only to begin horizontal
15:51:30 <nigel> ... review at "last call" or equivalent.
15:51:42 <nigel> tmichel: OK then I will send the prepared security questionnaire and the WD link to the
15:51:47 <nigel> ... other groups for horizontal review.
15:52:22 <nigel> action-481?
15:52:22 <trackbot> action-481 -- Glenn Adams to Provide nigel with a list of new features in ttml2 to begin reviewing -- due 2016-09-26 -- OPEN
15:52:22 <trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/481
15:53:20 <nigel> nigel: I will kick on with this action to draft a short description as a small number of
15:53:40 <nigel> ... paragraphs of prose, and send to you Glenn for review. Thierry, if you CC me in on your
15:53:53 <nigel> ... emails to the horizontal review groups then I can respond with this descriptive text.
15:54:16 <nigel> tmichel: Sure
15:54:19 <nigel> nigel: Thank you
15:55:09 <nigel> nigel: We have two pull requests outstanding - is there any reason not to merge those?
15:55:23 <nigel> glenn: I didn't have time to review and merge those before doing the WD, but will do so soon.
15:55:27 <nigel> nigel: OK, thank you.
15:56:10 <nigel> nigel: Should we raise https://github.com/w3c/ttml1/issues/220 lineHeight "computed" inheritance?
15:56:28 <nigel> glenn: A couple of implementations I reviewed consider the value "normal" to be considered
15:56:46 <nigel> ... a computed value for inheritance, and then calculate the actual line height further down the tree.
15:57:06 <nigel> ... That is consistent with the CSS behaviour.
15:58:00 <nigel> ... For percentages, they are resolved to an absolute value that is inherited. I have not checked
15:58:03 <nigel> ... the implementations of these.
15:58:25 <glenn> glenn has joined #tt
15:58:30 <glenn> https://www.w3.org/TR/CSS22/visudet.html#propdef-line-height
15:59:13 <nigel> pal: I think it's really important to note that the computed value of normal is "normal".
15:59:38 <nigel> ... Also not to change the algorithm in TTML for percentages. Whether we change the
15:59:51 <nigel> ... recommendation to authors about baseline jumping etc I do not have a strong opinion.
16:00:06 <nigel> glenn: I agree with you on this Pierre. If we feel it is important we can add a note giving
16:00:19 <nigel> ... advice to authors. I am not sure I understand the baseline jumping business so I need to
16:01:42 <nigel> ... review the thread - I think that the baseline jumping issue may not be a correct interpretation of the text.
16:04:29 <nigel> nigel: I've added a comment to the issue above.
16:05:53 <nigel> glenn: Now that we have a new WD will we be sending out liaisons requesting review?
16:06:12 <nigel> nigel: No, we should wait until we think we're at the "final" WD so that the wide review
16:06:26 <nigel> ... comments that we receive clearly apply to that version of the document.
16:06:38 <nigel> glenn: We did say in Lisbon that we would issue a WD for wide review in early November.
16:06:54 <nigel> nigel: Yes, and that was on the basis that it would be a "last call" style WD however since
16:07:06 <nigel> ... we are not ready for that but we want to initiate horizontal review we agreed last week
16:07:15 <nigel> ... to publish an interim WD.
16:07:32 <nigel> glenn: I would like to spend some time next week discussing how we proceed to a WD for
16:07:35 <nigel> ... wide review.
16:07:40 <nigel> nigel: Okay, good idea.
16:07:50 <nigel> nigel: We're out of time for today, thanks everyone [adjourns meeting]
