Abstract: According to one embodiment, an electronic device includes a keyboard, a backlight and a hardware processor. The backlight illuminates the keyboard. The hardware processor is electrically coupled to the backlight. The hardware processor is configured to gradually decrease brightness of the backlight during a period of time of which the backlight is continuously on.

Abstract: According to one embodiment, an electronic device provided with a touchpad includes a switching controller, a display processor, a notification processor and a notification controller. The notification controller is configured to control the notification processor to prevent a notification processing from being executed, even if an operation is performed on the touchpad, when the switching controller switches from a state of enabling an operation on the touchpad to a state of disabling an operation on the touchpad.

Abstract: An electronic apparatus of an embodiment includes a comparison section which, in the case where a long-life mode of a battery is set, compares a battery detection value with a second low-battery detection value that is higher than a first low-battery detection value. The apparatus further includes a change detection section which detects a change of a power supply. The apparatus further includes a change reflect section which, in the case where it is detected both that the battery detection value is lower than the second low-battery detection value, and that the power supply is changed, changes the low-battery detection value to the second low-battery detection value.

Abstract: 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.

Abstract: According to one embodiment, there is provided a digital TV capture unit electrically connectable to a system bus of a computer. The unit includes a signal processing circuit which receives both a first output signal output from the first digital TV tuner module and a second output signal output from the second digital TV tuner module, and performs signal processing including descrambling, a bus interface circuit which performs control of transmitting a signal processed by the signal processing circuit, and an arbitration circuit which controls signal output operations of the first digital TV tuner module and the second digital TV tuner module to assure that the first output signal and the second output signal are alternately transmitted to the signal processing circuit in synchronism with a predetermined clock in units of packets.

Abstract: A TV tuner capture unit not only can output video data compressed and coded by an MPEG2 encoder onto a PCI bus, but also can transmit uncompressed digital video data directly to a high quality video engine (HVE). The uncompressed digital video data is transmitted to the high quality video engine via a video data transmission path, and the PCI bus is not used. The high quality video engine corrects the image quality of the video data and then displays the video data on an LCD.
