Abstract: In one embodiment, an electronic device detachably connected to a mobile device is provided. The electronic device of the embodiment includes a power supply, a detector and a controller. The power supply is configured to supply power to the mobile device when the mobile device is connected to the electronic device. The detector is configured to detect whether a user is within the detector's range. The controller is configured to stop supplying power to the mobile device, when the detector detects a user while the mobile device is connected to the electronic device and to subsequently resume supplying power.

Abstract: According to one embodiment, an electronic device is connectable to a display and includes a television receiver configured to receive television broadcasting and to output a video signal. The electronic device starts up at least a part of the television receiver when the electronic device is connected to a commercial power source. The electronic device starts to output the video signal from the television receiver to the display when it is detected that a power switch is turned on.

Abstract: According to one embodiment, an information processing apparatus includes: a main unit; a first disk device provided in the main unit; a second disk device provided in the main unit; an acceleration sensor provided in the main unit and detecting an acceleration; a setting module for setting whether to execute a disk protection processing for at least one of the first disk device and the second disk device or not; and a controller for executing the processing on the disk device for which the execution of the processing is set by the setting module, when an acceleration is detected by the acceleration sensor.

Abstract: 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.

Abstract: According to one embodiment, a TV capture unit includes a wiring board. a first device provided with a first TV tuner and a second device provided with a second TV tuner are mounted on the wiring board. The wiring board includes terminals which are provided in correspondence to pins of the bus slot, and wiring lines which connect part of the terminals to the first and second devices. The wiring lines includes signal lines used for connection between a terminal corresponding to an unused pin to which no particular signal is assigned in pin assignment of an interface standard complied with by the bus slot or a terminal corresponding to a pin to which a signal irrelevant to an operation of a TV tuner is assigned and one of the first and second devices.
