Remote control transmitter/receiver system

摘要

A remote control transmitter/receiver system in which a transmitter transmits a signal incorporating a secret code and a command function. The receiver receives the signal from the transmitter, discriminates the secret code and command function and performs a user's command only if the secret code in the received signal coincides with a secret code set in the receiver. This remote control transmitter/receiver system includes a transmitter for converting a secret code and function signal into an encoded pulse signal and modulating the pulse signal to transmit the modulated signal. The remote control receiver receives the signal transmitted from the transmitter and demodulates the signal to output a function signal only when the secret code in the demodulated signal coincides with a secret code stored therein to thereby perform the user's command.
