ABSTRACT:
A consumer electronic device includes circuitry configured to produce a signal corresponding to a selected one of first, second and third radio frequency channel. The circuitry includes a modulator configured to modulate the video signal such that it falls within a first predetermined frequency range, corresponding to the selected channel. The respective frequency ranges for the first, second and third radio frequency channels are mutually exclusive. Multiple consumer electronic devices are coupled to a combiner which generates a combined signal including the modulated signals from all of the devices. This signal is distributed to a plurality of receivers such that each receiver can receive any of the modulated signals without interference from any of the other modulated signals. The device may also be implemented as a stand-alone device that receives baseband signals, modulates the signals and combines the modulated signals to produce the combined signal.
