   mike: what is defined in TTML1SE is adequate, i.e., note about

   ... FCC requirements to allow user to resize font may be use
   case for shrink fit size of region
   ... someone needs to look at what CSS supports in this area
   ... in which case we could define functionality using this CSS

   for CSS shrink-to-fit width discussion

   (display) device pixels

   <plh> scribe: plh

   pal: what's the proposed text?

   sean: [gives text]
   ... part of problem here is that ttml doesn't require a video
   object at all

Draft charter

   Nigel: that's a standing agenda item

   ... initial chairs is one
   ... idea is that I would become the other co-chair with David
   ... taking care of the TTML part
   ... that's the draft plan

   <nigel> [35]http://www.w3.org/2013/10/timed-text-charter.html

     [35] http://www.w3.org/2013/10/timed-text-charter.html

   Nigel: some wording in the deliverables
   ... on live production streaming
   ... not precise enough
   ... will come up with a proposal
   ... milestones
   ... quite a lot of crunch
   ... coming at the same time
   ... TTML 2.0 and IMSC might need to be revised

   pal: real need for ttml 2 and imsc and I think we can do both
   ... so no reason to have different timeframe
   ... imsc relies on ttml 2
   ... so imsc at best can happen on the same time scale

   nigel: it seems safer to put a bit of offset

   pal: we have a draft for imsc
   ... I hope we won't pushback ttml 2 further
   ... no significant issues against imsc
   ... so pretty confident with the timeline

   ... and approved in December

   nigel: can we get from FPWD to LC between January and April?

   pal: I'd like to get to FPWD asap

   nigel: to reverse the idea of the TPAC doesn't seem a good idea
