Title: Method and apparatus for adaptively scaling motion vector information in an information stream decoder

Abstract: A method and apparatus for reducing memory and memory bandwidth requirements in an MPEG-like decoder by compressing image information prior to storage such that a reduced resolution image information frame is stored and subsequently utilized by, e.g., a motion compensation module of the decoder. The invention responsively processes motion vector information in a manner consistent with the amount of compression imparted to a predicted image information frame, and the type of prediction employed in forming the predicted information frame.
