    Abstract: An application/game server comprising a central processing unit to process application/video game program code and a graphics processing unit (GPU) to process graphics commands and generate a series of video frames for the application/video game; one or more back buffers to store video frames as the video frames are being created in response to the execution of the graphics commands; a front buffer outputting the video frame for display one scan line at a time at a designated scan out frequency, a subset of scan lines stored in the front buffer being associated with a vertical blanking interval (VBI); and a frame processing module to begin copying a newly completed frame from the back buffer to the front buffer before the video data for a prior video frame stored in the front buffer has not been fully scanned out.

    Abstract: A system and method for efficiently processing a video stream using limited hardware and/or software resources. For example, one embodiment of a computer-implemented method for efficiently processing a video stream with a processor pipeline having a plurality of pipeline stages, comprises: identifying a bottleneck stage within the processor pipeline the bottleneck stage processing frames of the video stream; receiving a feedback signal from the bottleneck stage at one or more upstream stages, the feedback signal providing an indication of the speed at which the bottleneck stage is processing the frames of the video stream; and responsively adjusting the speed at which the one or more upstream stages are processing frames of the video stream to approximate the speed at which the bottleneck stage is processing the frames of the video stream.
