    摘要： Video frame buffers are controlled using a sequence of new-frame-indicators (e.g., FLIP) and no-new-frame-indicators (e.g., NOFLIP) in a frame indicator queue that is accessed with each display refresh. Video samples are loaded into a chain of video frame buffers that is “rotated” during the vertical blanking signal of the display to swap an old frame buffer out for a new frame buffer. The rotations of the frame buffer chain are controlled based on the frame indicators in the frame indicator queue to present new video samples to the display in a regular pattern, thereby providing smooth video playback.

    摘要翻译： 在每个显示刷新访问的帧指示符队列中，使用新帧指示符序列（例如，FLIP）和无新帧指示符（例如，NOFLIP）来控制视频帧缓冲器。 视频样本被加载到视频帧缓冲器链中，该视频帧缓冲器在显示器的垂直消隐信号期间被“旋转”，以将新的帧缓冲器交换出来用于新的帧缓冲器。 基于帧指示符队列中的帧指示符来控制帧缓冲链的转动，以规则模式将新的视频样本呈现给显示器，从而提供平滑的视频回放。

    摘要： An image of a first aspect ratio is modified to be displayed in a display area with a second aspect ratio. In doing so, the aspect ratio of some of the image content is approximately maintained, yet the aspect ratio of other areas of the image content is stretched so that the entire resulting image fills the display area. This may be done by either using texture mapping to map a strip of content (treated as a texture) into a strip of the destination image. It may also be done by modifying the image content to an intermediate image, which is then uniformly stretched to fill the intended aspect ratio. The areas of image content closest to one or more focus areas is approximately maintained, while other areas are allowed more distortion.

    摘要： A method, interface, and medium are provided for causing a computer to respond to input based on the source of the input. The computer responds to identical input according to a device that generated the input. The method includes determining information about a receiving component that received the data and using that information to determine the source of input. The source of data input is coupled with the input to initiate a response by the computer. The response can be tailored to how the data was received.

    摘要： A method for rebalancing bandwidth allocations to peripheral and other devices, particularly for isochronous communications, connected to a computer system via a bus in order to accommodate bandwidth requirements of a newly added device or newly launched application is described. The method is particularly useful in the context of buses such as the Universal Serial Bus (USB) and the IEEE 1394 bus (FireWire) which allow a plurality of devices to be connected to a computer system and even be powered by the bus. The method utilizes a Policy to identify preferred configurations and, furthermore, extends the USB and other standards to specify devices that can dynamically respond to commands to change their bandwidth to another setting.
