Issues and questions

Text outline doesn't handle different types of character edge.

http://dvcs.w3.org/hg/ttml/raw-file/tip/ttml10-sdp-us/Overview.html

R0037 The user must be able to specify the rendering of character edge types of: none, raised, depressed, uniform or drop shadowed edges.

mmartin3: Explains issues and cites Glenn's concerns.

mijordan: Add to future features is the right approach.

mmartin3: SMPTE liaison statement asks this be considered for a future version.

Issue mmartin3 Textoutline doesn't handle specific edge types outlined in R0037. Need to revise requirement and specify in Future Needs sections.

Issue: Textoutline doesn't handle specific edge types outlined in R0037. Need to revise requirement and specify in Future Needs sections.

<trackbot> Created ISSUE-191 - Textoutline doesn't handle specific edge types outlined in R0037. Need to revise requirement and specify in Future Needs sections. ; please complete additional details at http://www.w3.org/AudioVideo/TT/tracker/issues/191/edit .

EBU comment

Do we need to limit chars per line to target particular devices to adhere to FCC requirements for screen windows?

R0041

At most 32 characters must be present in any displayed text line.

mmartin3: Explains issues.
... Compatibility to EBU-TT.

andreas: We couldn't find a workaround.
... Teletext too.
... Manual conversion

mmartin3: Does making this a should address your concern?

andreas: Difficult for EBU-TT.
... OK, for a should.

Issue: R0041 doesn't allow for EBT-TT conversion easily. Revise R0041 to a SHOULD.

<trackbot> Created ISSUE-192 - R0041 doesn't allow for EBT-TT conversion easily. Revise R0041 to a SHOULD. ; please complete additional details at http://www.w3.org/AudioVideo/TT/tracker/issues/192/edit .

pal: What about the safe region in CEA-708D.

mmartin3: This is part of this question.
... We could put text that speaks to root container for regions?

scribe: TTML allows for inside and possibly invisible text. Relates to Issue-180 and Actions 104, 105.

<mijordan> from FCC 00-259 page 34: "(j) Pen Size. Decoders must support the standard, large, and small pen sizes and must allow the caption provider to choose a pen size and allow the viewer to choose an alternative size. The STANDARD pen size should be implemented such that the height of the tallest character in any implemented font is no taller than 1/15 of the height of the safe-title area, and the width of the widest character is no wider than 1/32 of the width of t

<mijordan> f the safe-title area for 4:3 displays and 1/42 of the safe-title area width for 16:9 displays. The LARGE pen size should be implemented such that the width of the widest character in any implemented font is no wider than 1/32 of the safe-title area for 16:9 displays. This recommendation allows for captions to grow to a LARGE pen size without having to reformat the caption since no caption will have more than 32 characters per row." [it appears the FCC left ou

np

mijordan: Accounts for decoder and the authored content.
... Make sure that we have constraints to support maximum compatibility with different players.
... Few folks are doing captions using 1/42.
... mijordan and mmartin3 will work on a proposal
