Why not just see if the screen image has changed in a given period
of time? At that point, a "fail-safe" procedure might be called that could
systematically send remote commands to the set top box to get it out of it's
deadend state. This might include turning the settop box off entirely.
This would be more general purpose and might catch other sort of error
conditions not originally accounted for.
This would also be a nice check for recordings so that they could be
automatically validated. Cleaning up after one of these deadend channel
changes can be a bit of a pain in the ass.
