epsulon,
From point A, I want to be able to take a video signal and other signals,
I assume the other signals are audio, at least in part. First let me say that
video and audio can't really be combined. A TV station produces two separate
signals, Video on AM, Audio on FM. So what you seem to want is a small
TV station. There are such devices on the market. I can't give you a source
at the moment, but if you check some very well stocked electronics catalogs
you might see something like that.
whatever purposes I need. I also need to be able, from point B, to combine
other signals minus video this time, and send them via radio to point A, and
at point A decode those signals and use them.
It looks like a more difficult project a beginner could handle unless you find
some
device designed for that purpose.
