Scalable Speed Search Technique for Digital VCRs
The requirement to develop a VCR, which is capable of performing search play at variable speeds (picture in shuttle) in both forward and reverse directions of interframe coded signals presents a difficult task. — This paper describes a new trick play technique for interframe coded (MPEG like) HD-VCR data. The technique is based on analysis made on required picture quality and it involves special positioning of the data for the “trick” play mode. The basic criteria is that picture quality which is inversely proportional to tape speed (lower quality at higher speed) is acceptable to the viewers.
