In the states, for digital TV we have MusicMatch audio stations, I've noticed 
at least for me they get broadcast in the clear, but the video channel for 
them is not linked like normal channels by the program ID, and when you find 
the video ID the video is more like a slide show where an image is sent out 
then nothing for some seconds then the next video image. Would something like 
this allow me to tune the audio PID and not worry about the video so I could 
at least listen to the station?
