摘要： An operation for combining multiple video streams permits combining any number of overlay images and base images regardless of processes performed upon one or more of the images. Specifically, where the base images are dynamically sized and resized to provide a constant frame rate (despite varying frame complexity), the process similarly treats overlay images and even other base images. In the dynamic sizing process, a rendering time is compared to high and low water marks. During dynamic resizing, two double buffering operations and a synchronization operation are performed. After dynamic sizing and resizing, the resulting resized images are combined together, regardless of the frame rate of the individual images. Consequently, multiple video streams at varying frame rates are combined at a constant frame rate.

摘要： A system and method for dynamically resizing graphic images of variable image complexity to generate display images at a constant frame rate for output to a display device. In one frame, an image resolution is determined and a graphic image is drawn to the determined image resolution. In the subsequent frame, the graphic image is magnified to a target resolution prior to being output to a display device. The synchronization of the drawing of the graphic image and its display is managed by a swap buffer signal. The present invention further provides for the double buffering of graphic images and their corresponding image resolutions. The present invention further provides for the independent dynamic resizing of multiple channels, such that, a plurality of display devices can independently resize graphic images of variable complexity at a constant frame rate.

摘要： A programmable video output format (VOF) generator that enables a processing system to drive different video display devices with varying video format requirements. The programmable VOF generator includes a compiler that generates video formats based on user input, and a state machine that generates all video signals with requisite output format. The compiler allows the user to provide minimal information on general display parameters using a high-level language. Therefore, no specialized knowledge of the video display hardware requirements is required from the user.

摘要： The present invention provides a system, method and computer program product for reducing fill and improving quality of interlaced displays using multi-sampling. In an embodiment of the invention, a frame buffer for a interlaced display is filled. Initially, a first multi-sample of the first line of the first field is calculated. The bottom sub-pixels of the first multi-sample are the top sub-pixels of a multi-sample of the first line of the second field. The first multi-sample is written into the frame buffer. Then, a second multi-sample of the second line of the first field is calculated. The top sub-pixels of the second multi-sample are the bottom sub-pixels of a multi-sample of the first line of the second field. Also, the bottom sub-pixels of the second multi-sample are the top sub-pixels of the second line of the second field. The second multi-sample is written into the frame buffer. A multi-sample for each subsequent line of the first field is calculated in this manner and written into the frame buffer. Then, a last multi-sample consisting of the bottom sub-pixels of a full multi-sample of the last line of the second field is calculated. The last multi-sample is also written into the frame buffer.
