<trackbot> ACTION-44 Put in place a new errata and ask plh to set up the redirect to it closed

plh: charter went to members for review
... no formal feedback so far
... some informal feedback about difference between ttml and webvtt

<plh> http://www.w3.org/2012/02/timed-text-wg-charter.html

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

plh: some comments have asked about use of 'MAY'

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

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

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

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

SMPTE, etc

mike: (1) does not necessarily have support for work
... (2) a study activity is underway in SMPTE to map TTML into MPEG-4 containers
... expects some input after May 4

ISSUE-158?

<trackbot> ISSUE-158 -- background images -- open

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

mike: SMPTE-TT defines an element and a couple of attrs to create an inline image and reference either inline or external image
... only format is image/png
... inline encoding allows inline coding of image/png
... on a div element, can put a reference to a background image that has a URI referring to background image for div
... used for long form content, especially for non-English content

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

mike: also used for refined placement of image based glyphs (rather than relying upon builtin fonts)
... semantics of what happens when both image and text content are provide may need more work

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

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

sean: should this be adopted into TTML11 NS?

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

sean: suggests mike write a CP
... or sean could take this as action

mike: notes that smpte specs are public

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

sean: wonders what smpte position would be?

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

plh: provides pointer

ISSUE-158: solicit CP

ISSUE-138?

<trackbot> ISSUE-138 -- Standard extension to support W3C ruby markup -- open

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

sean: can do manually, but currently no language support for ruby
... there are existing solutions in W3C for markup of ruby
... should we take a style driven approach or a markup approach?
... could use role to add one level of markup

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

scribe: don't want to reinvent the wheel here
... suggest a combination of use of style and role may be best approach
... more future proof

<scribe> ACTION: sean to issue call for CPs on ISSUE-138, suggesting approach based on combination of style and role [recorded in http://www.w3.org/2012/04/12-tt-minutes.html#action02]

plh: worried about I18N folks complaining about doing something different

sean: worried about introducing specialized markup

<mike> need to drop. until next week...

sean: notes it can be done today in ttml with foreign namespace

plh: worried that role sounds like a hack

Adjournment

adjourned

plh: regrets for next week
