REMOTE CONTROL METHOD AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce an increase in the power consumption caused by an erroneous remote control input or an input of a noise source in a standby mode at interruption of power. SOLUTION: A microcomputer control section 10 of a device body side 4 is provided with a power-on detection block 7 that is in operation by a low- speed sub clock in a standby mode of the control section 10, interprets an instruction code signal whose medium is an infrared ray sent from a remote control transmitter 1 and outputs a code matching pulse when the instruction indicates 'power-on' and with an interrupt control section 5 that captures the code matching pulse outputted from the power-on detection block 7 and outputs an interrupt request signal wake up a CPU 6.
