The FCC has regulations against interference, and unlicensed
transmission. If you push it into a cable system that you own, I
can't see any particular problem. Certainly the NTSC equivalent
is easy to come by: many apartment buildings have security-cam
channels, and similar installations are often done in high-end
home-theatres.
