Comment (by Jim Stichnoth <stichnot@…>):

 Revised patch adds support for formatting via preamble address codes.

 Also, changes the internal buffer representation of a format control
 character to a single QChar in the arbitrarily chosen 0x70nn range,
 instead of a "%n" pair of characters.

 At this point, the caption colors and italics look nice.  The mpeg2-ts
 test file
 http://ncamftp.wgbh.org/DTV/CEA%20test%20material/Iteration_1/CEAv1.2zero.trp
 located by faginbagin seems to display captions correctly as intended,
 except for two strings "biu" (blue/italic/underline) and "giu"
 (green/italic/underline), but I believe the test file is wrong and the
 implementation correctly follows the spec.

 BTW, when creating the ticket, I forgot to set the component (my best
 guess is video/osd rendering), in case someone wants to update it.
