14:04:50 [glenn]

14:06:00 [plh]

"In the process of producing this new revision, the Group MAY:"

14:06:40 [glenn]

... some comments have asked about use of 'MAY'

14:07:02 [glenn]

sean: the 'WILL' is for deliverables, the 'MAY' indicates optionality

14:07:02 [Zakim]

+Andrew_Kirkpatrick

14:07:20 [AWK]

AWK has joined #tt

14:10:15 [glenn]

glenn: could make item (1) and item (3) under TTML1.0/1.1 deliverables as 'WILL', but others probably should remain optional

14:10:51 [glenn]

sean: item (2) under TTML1.0 {TV compatible online captioning profile} may end up being a tech report/note

14:12:54 [glenn]

plh: suggests AWK to discuss with Carl (Carlgill) possible liaison issues (with WebVTT CG)

14:14:50 [glenn]

Topic: SMPTE, etc

14:15:09 [glenn]

mike: suggests mimic of 708 attributes

14:32:38 [glenn]

sean: can't find references

14:32:49 [glenn]

mike: for smooth scrolling, have to go back further

14:32:56 [glenn]

sean: what should this look like?

14:33:50 [glenn]

glenn: thinks that WGHB had provided a video in the past

14:34:10 [glenn]

... might be in the TT member archives

14:34:31 [glenn]

ISSUE-158?

14:36:17 [trackbot]

ISSUE-158 -- background images -- open

14:36:17 [trackbot]

http://www.w3.org/AudioVideo/TT/tracker/issues/158

14:37:09 [glenn]

mike: SMPTE-TT defines an element and a couple of attrs to create an inline image and reference either inline or external image

14:37:16 [glenn]

... only format is image/png

14:37:26 [glenn]

... inline encoding allows inline coding of image/png

14:37:58 [glenn]

... on a div element, can put a reference to a background image that has a URI referring to background image for div

14:38:14 [glenn]

... used for long form content, especially for non-English content

14:38:45 [plh]

--> http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.html roll-examples

14:38:52 [glenn]

... also used for refined placement of image based glyphs (rather than relying upon builtin fonts)

14:38:57 [plh]

s/roll-examples/roll-up examples/

14:39:32 [glenn]

mike: semantics of what happens when both image and text content are provide may need more work

14:39:46 [plh]

ACTION-62: see http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.html

14:39:46 [trackbot]

ACTION-62 Search TT member archives for reference to video showing smooth scrolling notes added

14:39:48 [glenn]

sean: should this be adopted into TTML11 NS?

14:40:02 [glenn]

mike: points out that can't use both, must choose image or text content

14:40:28 [glenn]

sean: suggests mike write a CP

14:40:44 [glenn]

... or sean could take this as action

14:40:56 [glenn]

mike: notes that smpte specs are public

14:41:11 [plh]

--> http://store.smpte.org/product-p/st%202052-1-2010.htm SMPTE-TT

14:41:18 [glenn]

sean: wonders what smpte position would be?

14:41:35 [glenn]

mike: would have to go back to smpte, but probably no issue

14:41:55 [glenn]

plh: provides pointer

ISSUE-138?

14:45:21 [trackbot]

ISSUE-138 -- Standard extension to support W3C ruby markup -- open

14:45:21 [trackbot]

http://www.w3.org/AudioVideo/TT/tracker/issues/138

14:46:25 [glenn]

sean: can do manually, but currently no language support for ruby

14:47:05 [glenn]

... there are existing solutions in W3C for markup of ruby

14:47:27 [glenn]

... should we take a style driven approach or a markup approach?

14:47:39 [glenn]

... could use role to add one level of markup

14:48:10 [glenn]

e.g., <span role='rb'>

14:52:02 [glenn]

... don't want to reinvent the wheel here

14:52:40 [glenn]

... suggest a combination of use of style and role may be best approach

14:52:45 [glenn]

... more future proof

14:54:03 [glenn]

ACTION: sean to issue call for CPs on ISSUE-138, suggesting approach based on combination of style and role

14:54:03 [trackbot]

Created ACTION-65 - Issue call for CPs on ISSUE-138, suggesting approach based on combination of style and role [on Sean Hayes - due 2012-04-19].

14:55:05 [glenn]

sean: worried about introducing specialized markup

14:56:04 [mike]

need to drop. until next week...

14:56:08 [Zakim]

-mike

14:56:44 [glenn]
