First of all keep in mind I'm a beginner. I would appreciate the groups help
in directing me for my project. This is something I have always wanted to
learn how to do. I think I want to make a carreer out of it.

From point A, I want to be able to take a video signal and other signals,
combine them into one, then send them out via radio. Then from point B
receive them, decode the signal, and use the video and other signals, for
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.

I can see many steps and components involved in getting this to work, and
would highly appreciate the groups help.

                                                                Jon

Hi Jon,

?

That sounds like?a real challenging project. Well, without knowing what other signals you want to mix with the video signal, I would say that first of all you need to code the signals so they don't interfere with each other. There are several transfer protocols you can use. I don't know what is best to use when it comes to RF though.

?

However, if the "other signals" are of frequencies outside what is used in the video signal, you might be able to mix the signals togheter and then filter them apart at the receiver side.

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.
