SYSTEM AND METHOD FOR VIDEO FRAME SEQUENCE CONTROL

摘要

A video sequence control system that includes an input video frame buffer and an output video frame selection component is described. The input video frame buffer receives input video frames from a video source. The output video frame selection component determines the video frame to be output according to a scheduler that provides timing information and modulation information. The timing information includes information regarding when a video frame will be output. The modulation information varies dependent upon the frame types available to be output, wherein the available frame types include at least image frames from the input video frame buffer and functional frames, wherein the at least image frames and functional frames are output according to a pattern defined by the scheduler. In addition based on the timing information, a synchronization output signal is output corresponding to the output of the functional frame.
