Video Transmitter Receiver

Can the audio channel from an audio/video transmitter/receiver pair be used for audio also?

on something like this:

Would it be possible to use the audio channel as a second video channel?

I think you are asking whether the sound channel can be used for video too, and the answer is no. It can be used to send any audio though, whether from the TV program or some other source. Usually this is for stereo sound, which means two separate channels of audio are available.
