<P>PROBLEM TO BE SOLVED: To provide a remote control signal receiving circuit for receiving a remote control signal, to the head of which a start signal is attached that can make an AGC circuit normally function, even if the circuit is provided with an AGC circuit and reduce battery consumption of a remote control transmitter. <P>SOLUTION: In the remote control signal receiving system wherein the remote control signal is amplified according to the AGC, a stopped clock is oscillated by a restart pulse included in the remote control signal to restart a control means and the control means extracts a control code from the remote control signal, the remote control signal is configured with the restart pulse comprising an ON part t2 and an OFF part t3 succeeding thereto; and remote control code pulses succeeding to the OFF part t3, wherein relations of the ON part time t2<the charge delay time t5, and the OFF part time t3> the discharge delay time t5' are satisfied, and the OFF part time t3 is selected longer than the ON part time t2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
