  • INFORMATION STORAGE MEDIUM WITH DATA STRUCTURE FOR MULTI-ANGLE AND APPARATUS THEREFOR
    Publication number: 20090022478
    Abstract: An information storage medium controls a multi-angle data reproducing apparatus by having a data structure including at least one clip for each angle, each angle clip being a data record unit of the multi-angle data for an angle. Each angle clip is divided into predetermined jumping units at jumping points and each is recorded in contiguous areas of the information storage medium. Using the clip jumping points as a link among the angle clips in which each angle clip is contiguously recorded provides efficient random access for reading the multi-angle data for angle change.
