ABSTRACT:
A video component interconnection system includes a single signal conductor video bus serially coupled between each of the video components for conducting video signal between the components. A switch located in series with the video bus separates the continuity of the video bus when it is non-conductive. A shunt switch arrangement coupled to the video bus at its junction with the series switch, applies an impedance substantially equal to the characteristic impedance of the video bus between the video bus and a reference potential, when the series switch separates the continuity of the video bus, in order to reduce ghost-producing reflections.
