Audio video instruction format switcher

A device for transmitting multiple control formats from an audio/video source to an audio/video monitor receiver. The device includes a high definition multimedia interface cable that has a plurality of communication channels, including a consumer electronic control channel. Furthermore, a pair of plugs are coupled to the respective ends of the high definition multimedia interface cable and can be coupled to audio/video sources and receivers. A pair of interface ports are further coupled to the high definition multimedia interface cable and communicatively coupled to the consumer electronic control channel. The device transmits a first control format on the consumer electronic control channel when the input port is not coupled to a switching device and transmits a second control format on the consumer electronic control channel when the input port is coupled to a switching device.
