ABSTRACT:
A system, method, and apparatus for reducing the video decoder processing requirements for rewinding a HITS stream are presented herein. During rewind of a HITS stream, the video decoder builds a clean reference picture. The clean reference picture is built by decoding each of the P-pictures in the EP-EP segment. However, because the P-pictures are not displayed, the decoder does not decode the portion of the P-picture below the last intracoded slice. The decoder can build the clean reference picture without decoding the portions of the P-pictures below the last intracoded slice because the subsequent pictures do not use the said portions for prediction.
