Abstract

PURPOSE: To secure an automatic switching through a remote control device when the video information is viewed through the information network, VTR and the like via the TV picture receiver.
CONSTITUTION: Signal switch 20 consists of remote control reception device 21 and change-over switch 8. The video detection output signal is applied from the TV picture receiver to terminal 9 of switch 8 via cable 5, and the video signal is applied to terminal 10 from the information network such as the TV telephone or the like via cable 6. At the same time, one side of the above mentioned video signal is delivered from the common part of switch 8 via cable 7 to be projected on the Braun tube via the video output amplifier. Reception device 21 comprises reception part 23 of the remote control device using the ultrasonic wave, electromagnetic wave, beam and others, signal converter 24, signal discriminator 25 and relay 26. And relay 26 switches switch 8 by the command given from the remote control device.
