摘要： A filter includes a conventional filtering block and a protection block. The conventional filtering block receives input values and provides filtered values. The protection block receives filtered values and a group of input values proximate the current input, to ensure that the output is lies within a range computed for the current input. The range is determined by the protection block based on the group of input values proximate the current input. Any algorithm or statistical function may be applied to the group of input values to determine the range. If a filtered value provided by the conventional filtering block is outside the range, then the protection block computes and outputs a value that is within the range. The filter may be used in temporal or spatial filtering of images and video to mitigate artifacts such as motion artifacts and static artifacts.

摘要： A video playback circuit receives flip call information and vertical synchronization information, and in response determines a pause mode and a playback mode. Flip call information, as is known in the art, provides an indication for flipping between a front buffer and a back buffer, in order to facilitate rendering into one buffer while rasterizing out of the other buffer. Vertical synchronization information describes the completion of rasterizing an image onto a display, and often occurs at periodic intervals, e.g., 60 Hz, 100 Hz. The video playback circuit further includes a pause/playback-based frame buffer pointer information generator. The pause/playback-based frame buffer pointer information generator generates unfiltered frame buffer pointer information when in the pause mode. Otherwise, the pause/playback-based frame buffer pointer information generator generates filtered frame buffer pointer information when in the playback mode. The unfiltered frame buffer pointer information indicates rasterization of unfiltered rasterization data from the frame buffer during the pause mode. Similarly, the filtered frame buffer pointer information indicates rasterization of filtered rasterization data from the frame buffer when in the playback mode.

摘要： A method for displaying images on multiple monitors with different refresh rates is disclosed. To prevent screen tearing, the surface containing image data is not released when the access by the master monitor is completed until the slave monitor or monitors finish access. To synchronize images with a predefined playback speed, the surface containing a new image received from the application is not flipped onto the screens until receiving a predefined synchronization indicator.

摘要： A first set of display information is received at a device driver. The first set of display information indicates a portion of the video image to be displayed in a first window of a first monitor. An aspect ratio of the video image is determined based on the first set of display information. Based on the determined aspect ratio, the display driver determines a location on a second display device where the video image is to also be displayed.
