Abstract
A video display apparatus and method for displaying decoded video frames from an encoded video stream utilizes a display time difference determinator that detects a frame display time difference, on a per frame basis if desired, between a refresh rate based frame display time, and a video playback frame rate display time to generate frame display time difference data. This is done on a continuous basis to detect synchronization problems between video data that is to be displayed simultaneously with non-video data on a display device such as a progressive display screen. A pixel blender blends pixel data from an adjacent frame, such as an already reconstructed previous frame or next frame, to create a temporally adjusted frame based on the determined frame display time difference data.
