Apologies if this is outside the purview of this forum, but I thought that if people here are doing fun things with all kinds of sound, why not?
I'm curious to know if anyone here has used a video signal AS an audio signal. I'm doubly curious to know if anyone has ever recorded video to an audio format (tape, digital, vinyl, etc.), and has then been able to transcode back to video.
Am I correct in thinking the obstacles have to do with bandwidth? My understanding is that a black and white video signal can be up to 5 Mhz, obviously problematic for audio media.
Pixelvision and Vinyl Video seem to have overcome these obstacles. In the case of the former, the solution was to speed up the tape, effectively increasing bandwidth. I'm not sure about the latter - looks like they've employed some kind of mystery decoder box.
But what if you wanted to be able to encode and decode video without extra hardware, using the medium's standard speeds/sample rates? Are there any suggestions on creating a "low bandwidth" video signal, which could maintain useful information in the audio range? Or would you suspect that the only way to make this happen would be to use some kind of encoder/decoder? Or the more likely answer, which is that there's something I haven't even thought of!
