Abstract
A remote control circuit for a system wherein several terminal units are operatively connected to a single main unit, enabling the main unit to be controlled by the terminal units. The remote control circuit includes a remote control receiving unit equipped in a TV system and adapted to receive and process a remote control signal from a remote control transmitter, and a TV control microprocessor adapted to analyze the remote control receiving unit so as to output a VCR remote control signal and TV control signal based on code information of the remote control signal. The VCR control signal is transmitted to a VCR system by a VCR control signal transmitter, via a radio frequency cable. The VCR control signal includes a control signal converter and a pulse width modulator. In the VCR system, original VCR control signal is recovered, by a band-pass filter and a rectifier. The VCR control signal is converted into code information, by an A/D converter, which code information is applied to a VCR control microprocessor, so as to control the VCR system.
