ABSTRACT:
An improved method and apparatus is disclosed for communicating control information between components of an audio/video system. Processing and control logic is implemented to transfer a plurality of data streams on predetermined channels of a digital video interface. A first data stream contains video data received by a video interface receiver, where it is used to generate an image on a digital display. A second data stream contains control data, which is similarly received by the video interface receiver, and is used to control source devices coupled to the digital display.
