Abstract
A method and apparatus for processing an information stream comprising a plurality of compressed information frames to produce an information sub-stream having a reduced number of information frames. In the case of an MPEG video information stream, the information sub-stream is suitable for use as a fast-forward (FF) or rewind (REW) stream in, e.g., a video on demand (VOD) system utilizing such streams.
