Abstract
PURPOSE: To control a video signal generating device, which is provided in a master television receiver, from a slave television receiver through a transmission line through which sound signals are transmitted from the master television receiver to the slave television receiver.
CONSTITUTION: Video signals are supplied from a master television receiver to slave television receivers 4a, 4b∼ through cables 3a, 3b∼, switches 7a, 7b∼, buffer amplifiers 6a, 6b∼, etc. Meanwhile, sound signals are tramsmitted to slave television receivers 4a, 4b∼ through a shield line 17 for transmission of sound signals. A remote control device 19 is provided in the slave television receiver to transmit a control signal having a frequency band higher than that of sound signals to the master television receiver through the transmission line 17. In the master television receiver, the control signal is demodulated in a control signal receiving circuit 21 and is supplied to a video signal generating device such as a tape recorder. Thus, the remote control is possible without providing a control signal line separately.
