Abstract
This paper describes a method to permit a videocassette recorder (VCR) to search play at variable speeds (picture in shuttle), in both forward and reverse directions of interframe coded (MPEG-like) signals. Also discussed is a new “trick play” technique for interframe coded HD-VCR data. This technique is based on analysis of required picture quality and involves special positioning of the data for the trick play mode. Its basic criterion is that picture quality that is inversely proportional to tape speed (lower quality at higher speed) is acceptable to viewers.
