PURPOSE:To make the processing by a microcomputer efficient by making the hardware discriminate whether or not a received input signal is a correct remote control reception signal. CONSTITUTION:The circuit is provided with plural comparison data latches 108-111 to previously set data to discriminate whether or not a received input signal 101 is a correct remote control reception signal, a comparator section 107 to compare data of the comparison data latch with a counted value counted by a counter 106 based on an edge detected result of an input signal, plural flip-flop circuits(FF) 112-115 to set the resulted data by corresponding one-to-one basis to the comparison data latches, and a logic gate section 116 to output reception data 117, a reception data signal 117 or a reset signal 119 according to the set state of the flip-flop circuit. |
