An apparatus and method is disclosed for providing an extensible information handling system (IHS) bus implemented on predetermined channels of a digital video interface. IHS video signal information is multiplexed with IHS bus information by a host multiplexer for transmission across a digital video connector. The multiplexed IHS video signal and IHS bus information is received by a display multiplexer, where it is demultiplexed. Demultiplexed IHS video signal information is received by a video interface receiver, where it is used to generate an image on a digital display. Demultiplexed IHS bus information is received by a host bus interface transmitter/receiver, where it is used to support peripheral devices attached to the digital display.
