I suspect that those screens (in the UK at least) are generated
by MHEG pages on the channel.

What this means is that the PMT info changes from having a
video + audio stream to a data channel with only the screens
telling us that the channel is off air. I also suspect that there
is information in the PMT that tells us the channel is currently
off air, but I have no information to prove this one way or the
other.

Guess I'll just have to keep working on the Interactive TV stuff
which will add support for all of this....
