    • A computer and a method for enabling remote communication to a computer operating in a power-saving mode in which one or more one power sources to internal devices are disabled. The computer is equipped with a power management control circuit which is responsive to a first signal indicating that a device used to receive remote communication is to receive power while operating in a power-saving mode. In the event that a remote communications is detected which is targeted for the computer, a second signal is asserted by the remote communications device. The power management control circuit responds by exiting the power-saving mode and restoring power to the disabled power source to enable the computer to process the incoming communication. The remote communication may be through a wireless source such as a radio frequency channel or through a fixed wire such as a telephone network or LAN. Other aspects of the invention enable communication through an option card installed in a option slot or a notebooks docking station such as a radio device, modem, or LAN adapter.
    • 一种计算机和方法,用于使得能够以功率保存模式工作的计算机进行远程通信,其中禁用了一个或多个内部设备的电源。 计算机配备有电源管理控制电路,其响应于指示用于接收远程通信的设备在以功率节省模式操作的同时接收电力的第一信号。 在检测到针对计算机的远程通信的情况下,由远程通信设备断言第二信号。 电源管理控制电路通过退出省电模式并恢复到禁用电源的电源来响应,以使计算机能够处理进入的通信。 远程通信可以通过诸如射频信道的无线源或者通过诸如电话网络或LAN的固定线路。 本发明的其他方面能够通过安装在选项槽中的选项卡或诸如无线电设备,调制解调器或LAN适配器的笔记本对接站进行通信。

    • A display mode switching device and method automatically switches a display mode of a television set to an overscan mode or to an underscan mode depending on a content of a screen. In a case of connecting a television set to a computer, a call from an application for an API in an OS is detected by a device driver when a user starts playing a DVD or a game. Accordingly, an output mode for the television set is switched to the overscan mode. In this way, a motion video or a game is displayed on the television set in the overscan mode. Meanwhile, when the user finishes playing the DVD or the game, a call for the API to release resources is detected by the device driver, and the output mode is restored to the underscan mode. In this way, a computer screen is displayed on the television set in the underscan mode.
    • 显示模式切换装置和方法根据屏幕的内容自动地将电视机的显示模式切换到过扫描模式或欠扫描模式。 在将电视机连接到计算机的情况下,当用户开始播放DVD或游戏时,由设备驱动程序检测来自OS中的API的应用的呼叫。 因此,电视机的输出模式切换到过扫描模式。 以这种方式,以过扫描模式在电视机上显示运动视频或游戏。 同时,当用户完成播放DVD或游戏时,设备驱动程序检测到API释放资源的呼叫,并且输出模式恢复为欠扫描模式。 以这种方式,电视机屏幕以欠扫描模式显示在电视机上。

    • This invention relates to a video graphic control method and controller for sending to a display device graphic data from a processing device, and the object thereof is to provide a video graphic controller that increases the bandwidth available to a graphic engine or CPU without increasing power consumption or manufacturing costs, even when used with a conventional frame memory. A video graphic controller for controlling video data by storing the video data from a CPU 4 in a frame memory 18 and causing the frame memory 18 to output the data to a display device 30 uses a video data comparison means 20 to compare a piece of video data stored in the N-th address of the frame memory 18 to another piece of video data stored in the N-1-th address in order to determine whether the two pieces of data match, and if the two pieces of data match, outputs to the display device 30 the piece of video data stored in the N-1-th address instead of the piece of video data stored in the N-th address.
