Abstract
A video program length is changed by processing an MPEG compressed video signal. Two temporally adjacent B-frames are selected, by looking for pairs with small differences. The selected B-frames are combined to create at least one intermediate frame; which is inserted in place of or between the selected frames. Presentation time stamps are altered to provide a uniform display rate.
