PURPOSE:To eliminate a need for many remote control transmitters for respective equipments to be controlled by receiving signals from remote control transmitters provided in the said equipments, writing their contents in a memory, reproducing them and transmitting the results. CONSTITUTION:The remote control transmitter is assumed to modulate at approximately 40kHz by an infrared output. In a receiving part 5 to receive an optical signal, the signal is converted to an electric signal, and amplified in an input amplifier 6, then demodulated and waveform-shaped in a demodulating waveform shaping part 7, and further decoded by a remote control signal decoding part 8 to be stored in a memory 10. The writing in the memory 10 is executed under the control of a memory write/read control part 11 by using a signal generated from a write start signal by the part 8. When the memory 10 is made in a read state by means of a key switch 9, a signal (c) that shows a data corresponding to the address specified by the switch 9 is read out from among the content written until now in the memory 10, and a remote control signal generating part 12 is driven by a signal (d). |
