Patent ID: 7684433

Claim:
An apparatus comprising: a source multiplexer for connecting to a video source wherein the source multiplexer comprises: a source multiplexer input port for receiving an analog video signal from the video source; a source multiplexer output port for driving the video source with an upstream data signal; and a source multiplexer bi-directional port for coupling the analog video signal from the source multiplexer input port to a video cable and for coupling the upstream data signal from the video cable to the source multiplexer output port; a lowpass filter for passing the analog video signal and blocking the upstream data signal at the source multiplexer input port; and a bandpass filter for blocking the analog video signal and passing the upstream data signal at the source multiplexer output port; and a sink multiplexer for connecting to a video sink wherein the sink multiplexer comprises: a sink multiplexer input port for receiving the upstream data signal from the video sink; a sink multiplexer output port for driving the video sink with the analog video signal; and a sink multiplexer bi-directional port for coupling the upstream data signal from the sink multiplexer input port to the video cable and for coupling the analog video signal from the video cable to the sink multiplexer output port.
