<p>In a DUT which comprises a DUT header, sub video data, audio data, and main video data, the main video data is compression-encoded data of MPEG, and a predetermined number of GOPs (Group of Pictures) that is an encoding unit are assembled to compose the main video data in one DUT. Data in the DUT is divided by a plurality of sectors on a physical format. Hereby, random access is ensured from an optical disk on which the compression-encoded video data is recorded on the data unit basis (DUT), the DUT including a predetermined number of GOPs. <IMAGE></p> |
