Patent abstract
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.
