	Well, the traditional solutions involve some combination of
digital TV (which you allude to in the next paragraph) and/or frequency
division multiplexing, which has existed for quite some time.

	Note that FDM is what makes cable TV possible to begin with.  
As far as the cable is concerned, there isn't much of a difference
between another TV channel and data.

	I'm not sure this is really any easier than existing analog 
FDM techniques.
