Abstract
A method and an apparatus perform an inverse telecine procedure on a video sequence to eliminate redundant information introduced by the telecine process, so as to achieve more efficient data compression. The method and apparatus maintain synchronization between audio and video portions of the video sequence by ensuring that 20% of all frames, distributed substantially uniformly over the video sequence, are deleted. One embodiment of the present invention is provided in desktop computer system.
