ABSTRACT:
Apparatus for achieving contact-less linking between a transmitting unit and a receiving unit when transmitting video signal, audio signal, control signal, or digital data therebetween. The apparatus includes a switch circuit which switches the output signal of a light emitting integrated circuit to a first set of light guides for spatial transmission of an optical signal representing the video, audio and control signals and digital data and to a second set of light guides for near-by transmission of the optical signal.
