Abstract
A wireless audio and video signal transmitter and receiver system apparatus capable of accepting both external baseband audio and video signal inputs and a modulated external audio/video signal modulated at a particular television channel. A transmitter transmits an audio/video signal to one or more remote receivers which regenerate the original audio/video signal providing both baseband audio and video signal outputs as well as a modulated audio/video signal output at the particular television channel. The transmitter includes a modulated audio/video signal input section and baseband audio and video signal input sections which provide audio sub-carrier and video baseband signals to a video/RF switch which permits the user to select between modulated and baseband inputs to the transmitter. The audio/video signal is AM modulated and up converted before being transmitted to the receiver. The receiver down converts the received audio/video signal and through which a modulated audio/video signal output section connected to baseband audio and video signal output sections serves to provide both modulated and baseband audio/video signal outputs.
