Remote control system
专利汇可以提供Remote control system专利检索，专利查询，专利分析的服务。并且PURPOSE: To remote control an infrared ray remote control type equipment without laying a long cable for transmitting a remote control signal from a TV room to a VTR room by converting an infrared ray signal to an electric signal, superimposing the signal on a picture signal cable to transmit the signals.
CONSTITUTION: In the A room, a TV30 is disposed and in the B room, VTRs 32, 33 are disposed and the VTR 32 and 33 have infrared ray remote control signal receivers 40, 41. The first repeater 54 consists of a photodetecter 58 and an amplifier 60 and the second repeater 47 is constituted of a driving circuit 49 for current-amplifying the remote control signal and an infrared ray light emissitting diode 51. When a stop key for an infrared ray transmitter 51 is depressed to the first repeater 54, the infrared ray signal is photoelectrically converted in the first repeater 54, and the electric remote control signal is transmitted to the B room through a mixer 52, a coaxial cable 50. In a separator 48, the remote control signal is separated, the second repeater 47 forms the infrared ray signal from the remote control signal to emit to the VTR 32 and the VTR32 executes a stop operation.
