With the current technology in use, this can't be done. The compression technique used does not lend itself to very graceful failure. If part of the information that is sent to your receiver has a glitch, then there is a good chance the entire frame, or several frames, will be FUBAR.
The data is not sent as a constant stream as in analog TV. It's sent as separate packets of information that must be reassembled in the receiver in order to reproduce each frame or an entire set of frames. If the right information is missing, for whatever reason, you might miss an entire section of the broadcast.
Whet pisses me off about digital TV is that even with the best HD signal source, the picture sucks. We really are getting shafted by what they charge as compared to what they give us and most of us don't even know it.
