Abstract

Schemes for rewinding a HITS stream in video recorder and playback systems are presented herein. Reference pictures are stored for a group of pictures, allowing subsequent pictures to be decoded from the reference pictures. The foregoing significantly reduces the number of picture decodes required to display a HITS stream in reverse order.
