It's been a while since I've posted here. I've been very tied up with the project to get licensed 405-line TV back on the air again in the UK. The vision and sound transmitters are complete at last and attention is now being directed to building the transmitting aerial. Anyway, I digress...
I have in my possession a mechanical 30-line colour monitor that I built many years ago - the "Grosvenor" (since converted to horizontal scanning to take advantage of the 30-line standards available from my WC-01 converter) and what was once a matching mechanical colour camera, using R,G, and B photomultipliers. This camera will now also have to be converted to horizontal scanning.
Wiring up multiway RGB cables between the two units is such a fag... so what I would like to do is convey the colour pictures from the camera to the monitor over a modulated ultrasonic sound link... say 40kHz. Do you think this will be possible? I guess getting sufficient bandwidth out of (resonant) transducers will be a problem. Maybe I can use a higher carrier frequency with a piezo crystal? Which club colour encoding/decoding standard should I use? Remember I want to stick to 30-lines horizontal (because I have an excellent pair of disks that give a large bright square picture) and not change to 32-line vertical.
Thanks for any help received.
