Abstract
A method of displaying variable rate video data includes receiving a signal from a display indicating that the display is ready to accept a frame of video data, analyzing image content of scenes in the video data, using the image content of scenes in the video data to cluster the scenes into scene types based upon a motion level, adjusting motion estimation and motion compensation to produce a variable output frame rate of the video data not synchronized with an input frame rate, the variable output frame rate based upon the scene type, wherein the variable output frame rate employs interpolated frames, wherein interpolated phases used to form the interpolated frames are determined by the motion level and a phase relationship between the input frames and the display timing, receiving the video data at the variable output frame rate at a display panel, and displaying the video data at the variable output frame rate.
