Patent number: 6747567Abstract: An electronic apparatus wherein a remote control signal received via a filter is decoded and, upon deciding that the control signal is a power cutoff instruction, a controlling microcomputer outputs a filter control signal for actuating the filter to place the apparatus in a reception standby mode while the microcomputer itself is also set in its low power state, hence preventing a malfunction that some noise derived from external light of a fluorescent lamp or the like is recognized erroneously as a remote control signal and that the apparatus is shifted in error from the low power state to its wake-up mode. Consequently, the power consumption can be reduced in the standby mode. The remote control signal consists of a fixed-width pulse and a succeeding control code, and upon detection of the fixed-width pulse, the controlling microcomputer is released from the low power state to wake up and then halts the operation of the filter.Type: GrantFiled: March 13, 2001Date of Patent: June 8, 2004Assignee: Sony CorporationInventors: Toshio Amano, Kenichi Konuma, Toshihisa Ueki
