Abstract

PURPOSE:To make it possible to move a monitor receiving machine freely and make the monitor receiver small-size and light-weight, by using a light signal havving directivity to transmit and receive signals between the tuner and the monitor receiving machine. CONSTITUTION:When a remote control signal is transmitted from remote control transmitter 7, this signal is received by receiving part 6 of tuner unit 3, and unit 3 performs the channel selection operation for a prescribed channel on a basis of the remote control signal. Then, the light signal modulated by the video intermidiate frequency signal corresponding to the selection channel is emitted by light emitting part 5. If optical axes of light emitting part 5 of unit 3 and light receiving part 2 of monitor receiving machine 1 are caused to agree with each other previously, the light signal emitted from light emitting part 3 is received by light 1 receiving part 2 and is coverted to an electric signal in monitor receiving machine and is processed similarly to the normal receiving machine. As a result, the video is projected onto the receiving tube screen, and sound is emitted from the speaker.
