Digital TV was spec'd out with the ability to have multiple sub-channels plus various extra non-AV types of data in each stream. Is there any consensus about what types will usually be carried on cable or satellite?


I'm guessing that multi-must-carry will not come about and that any type of PSIP or caption data probably WILL be carried, no matter what's in it. Anyone disagree? What about other types of data that can be embedded in the primary program stream? Anybody know the current FCC stance? Or even current common practice?

This could pretty much set the standard of what actually gets used since broadcasters these days seem to mostly care about cable carriage and may not invest practically anything for antenna-only material.

Also, anybody know what current integrated digital TV's usually support?
