Abstract
The present invention provides a method for improving playback consistency of an encoded video stream. The method of the present invention first determines whether a series of values of the progressive_frame flag of consecutive frames of the encoded video stream are arranged in a predetermined pattern. If the values are arranged in the predetermined pattern, an image of at least one of the frames is displayed progressively regardless of the value of the progressive_frame flag of that frame. As a result, the video stream is played back as if the movie had been consistently encoded in the first place.
