As I understand it, this is roughly how it *is* done: you make a TV picture
where the image is something that you can tear apart digitally (shades of the
old CRT computer memories !-)  For a while, WGBX TV Boston was running an
experimental encoding system where they would transmit digital audio in the
picture frames, with the audio from WGBH FM for reference in the audio channel.
You could actually SEE the bits.  Very entertaining watching (for a few seconds
anyway).
