   new errata and ask plh to set up the redirect to it -- due

   <plh> close action-44

   <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> [12]http://www.w3.org/2012/02/timed-text-wg-charter.html

     [12] 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

     [21] 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> -->
   [22]http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.
   html roll-up examples

     [22] http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.html

   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

   html

     [23] http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.html

   video showing smooth scrolling notes added

   sean: should this be adopted into TTML11 NS?

   choose image or text content

   ... or sean could take this as action

   mike: notes that smpte specs are public

   <plh> -->

   <mike> smpte-tt schema -

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

     [27] 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,
