mmartin3: Explains issue.

Mike suggested document conformance.

Sean: Both are specified in the profile.

Mike: Use of profile was related to document conformance.

Sean: TTML 1.0 allows profile on processor.
... SDP-US is focused on document conformance and sufficiently constrain to deliver profile.
... CFF can be part decoder.

Mike: CFF model is about document authoring.
... Make a few revisions in TTML 1.0 SE to clarify that document conformance applies.

Sean: Agree.

Resolve to make SDP-US a document conformance profile.

Mike: Will develop sentence to change TTML 1.0 SE.

Sean: How to capture CFF constraints if document authoring?

Issue-188

pal: Describes issue.
... Doesn't set constraints of the document - characters, regions, drawing, etc.
... characters per second for example.

Sean: Explore document authoring constraint - Mike.
... How does this relate?

pal: CFF has rendering model that answers this question.
... Template can be used.
... Limit characters that author stream that the renderer has to process.

Sean: Synchronic document model - 2 points in time, document display to t1, t2. Differ by certain number characters?

Mike: Treats performance limitations for simplicity. Acts on each of sychronic document.

c/sychronic/synchromic

c/synchromic/synchronic

Sean: Characters per second doesn't make sense in synchronic documents.

mmartin3: CFF model targets specific use cases correct?

pal: No, SDP-US doesn't speak to these aspects?

Sean: Cast in TTML text, duration to render an instance.

pal: How much processing allocated to rendering? Character drawing is complicated. How many characters per second?

Sean: In captions, end of one document and start of the second specifies what to do and how to specify the stream.
... i.e. 4 seconds to draw.

pal: Put in SDP-US?

Sean: Create constraints that relate to synchronic document.

Mike: Recast in a different language is an issue.

Sean: They will be different because the 2 profiles are different.

pal: When CFF sets limits on drawing rate, what does the average of 120 characters mean?

Mike: Concerned about making them different.

pal: We seem to agree on character constraints.
... Benefit with compatibility on use of CFF. 2 items to address.

Action Sean to recast the constraints for the SDP-US.

<trackbot> Created ACTION-113 - Recast the constraints for the SDP-US. [on Sean Hayes - due 2012-10-11].

<trackbot> ISSUE-189 -- do regions scroll their flowed content? -- raised

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/issues/190

mmartin3: Describes issue.
... Suggest a note.

Sean: Add an example too.

Mike: Wasn't initially clear to me.

Sean: TTML 1.0 describes this. Have to understand XSL.

Mike: This is a TTML issue.

c/TTML/TTML 1.0

Sean: Decide if put in Second Edition or SDP-US.
