Sorry for the late answer, moving apartments took a bit of time.
Subtitle decoding will be a tricky subject. I would prefer not to send
redundant video frames, and just send one for each set of subtitles, and for
DVD's these frames would be bitmaps.
The format provides a bitmap with start time and duration, and I thought it
would be possible to send regular video frames with a long latency, or would
it be better to implement a new kind of "bitmap track"?
It might even be foreseeable to fuse both text and bitmap based subtitles at
one point, as I imagine that text based subtitles would have to be provided
as bitmap at one stage.
After further thought, menu overlays would need a lot more flexibility...
Do you have any ideas about mouse interaction with overlays?
Anyway, I'm just thinking aloud...
Cheers,
Christopher
