Abstract
Receiver control circuitry of a receiver automatically detects, selects, and enables a priority signal provided to the receiver from a plurality of audio and/or visual source devices. Upon the user starting a source device that serves as a potential source of audio and/or visual input signals to the receiver, the receiver control circuitry automatically determines whether the receiver should switch to the source device as its source of audio and/or visual information. Additionally, the receiver control circuit will automatically turn on the receiver if it is not powered-up so that this will not have to be done by the user of the receiver.
