According to one embodiment, an electronic apparatus includes an input module, a tuner, an amplifier and a preset module. The input module receives a television broadcast signal. The tuner selects a television broadcast signal of a target channel from television broadcast signals of channels receivable by way of the input module. The amplifier amplifies the television broadcast signal supplied to the tuner. The preset module determines whether each of the channels is receivable or unreceivable and to turn on or turn off of the amplifier, based on a first reception status information of the television broadcast signal of the reception channel acquired from the tuner in a state that the amplifier is on and a second reception status information of the television broadcast signal of the reception channel acquired from the tuner in a state that the amplifier is off.

Electronic apparatus and method of presetting reception channel

An information processing apparatus includes a receiving device and a control unit. The receiving device includes a plurality of processing unit containing an interface unit. The control unit includes an input source detection module, a transfer instruction detection module and a power-saving control module. The input source detection module detects an input source necessary for execution of a video reproduction program. The transfer instruction detection module detects a video data transfer instruction from the video reproduction program. When the video data transfer instruction is detected, the power-saving control module enables some of the processing units except the interface unit and sets the others of the processing units in power-saving mode. The enabled processing units receive a video signal from the input source detected by the input source detection module and convert the video signal into video data of given format.

Information processing apparatus having receiving device that receives video data

According to one embodiment of the invention, an information processing apparatus comprises a receiving unit to receive video data, a driver and a control circuit. The driver is configured to detect a start and an end of a video reproduction program that reproduces the video data received by the receiving unit. In communication with the driver, the control circuit is configured to change a state of the receiving unit from a power-down state to an operative state when the start of the video reproduction program is detected, and to change the state of the receiving unit from the operative state to the power-down state when the end of the video reproduction program is detected.
