<p>The apparatus is for interconnecting separate components (10-16) of a home entertainment system. It includes separate single signal busses (28; 30; 32) for transferring video and left and right stereo audio signals produced by one of the components to at least one other component. Switches (114; 120; 122) located in series with the video and audio busses break the continuity of the busses, when the switches are nonconductive, into sections. Thus signals can be transferred between components on one section, independently of the transfer of signals between components on another section. A shunt switch arrangement (117) coupled to the video bus (28) at its junction with the video series switch (114), applies an impedance (118) substantially equal to the characteristic impedance of the video bus, between the video bus and a reference potential (GND), when the series switch breaks the continuity of the video bus, in order to reduce ghost-producing reflections.</p> |
