Hi All,
A question for you clever guys and gals -
I am using a conventional radio control unit (as used for model planes) to activate servo motors in an experimental setup. This works well but I now want to add video feedback from a camera. Radio control is really not a preferred option for me in this appllication and to keep the overall system simple, a cable would actually be better. The separation diistance is about 200ft. The cable needs to be as small as possible.
Is it possible to achieve all of the communications including video down just a single co-ax? By this I guess I mean can either of these work? -
A) A single co-ax cable carrying the video but could I somehow 'add in' the modulated RC control i.e. get rid of the aerial at each end and suppliment the transmitter and reciever with some electronic interface to make the direct cable connection. Would the modulated RC signal screw up the video or visa-versa?
B) Could I achive the same effect but not using the RC unit. i.e. again by adding a modulated control signal to the video conection.
In order to keep the cable simple, cheap and lightweight, I don't really want to go for a more conventional video plus RS422 twin screened twisted pairs setup.
Your comments, and any recommendations, humbly recieved.
Thanks
