Abstract:
1. An electronic device comprising: a receiving circuit configured to receive remote control signals from a remote control device; an electronic device body including a signal processor for processing input signals and configured to perform at least one of video processing and audio processing based on signals processed in the signal processor in accordance with the remote control signals received by the receiving circuit; an activation circuit for initializing an electric power supply which powers the signal processor to activate the signal processor when a pre-operation state is detected in the remote control device; a detection circuit for detecting the occurrence of the pre-operation state by detecting a predetermined physical quantity, wherein the activation circuit performs the activation processing when the pre-operation state has been detected by the detection circuit; a storage device for storing the detected physical quantity and information as to whether or not the control signal has been received from the remote control device in a correlated manner; and a threshold calculation circuit for calculating, based on the contents stored in the storage device, a threshold of the physical quantity for determining whether or not the activation processing of the activation circuit is to be performed, wherein the activation circuit performs the activation processing when the pre-operation state has been detected by the detection circuit and when the detected physical quantity is larger than the threshold.
