There are devices that do what you want (a 'channelizer').  Basically 
they take a video source input and modulate it for transmission over a 
(typically unused) tuneable cable-TV frequency.  Usually they recommend 
putting a one-way filter on your cable coming into the house, so that 
the outside world can't view your transmission, but that is not 
necessary if you run your own cable feed separate from your TV cable.

Unfortunately, I don't have a link, company or product name handy... but 
I know I've seen such things advertised.
