Abstract
A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.
