Abstract
On an optical disk, video object sets (VTST_VOBS) to be reproduced and video title set information (VTSI) serving as management information on the video object sets have been stored. In each video object set (VTST_VOBS), many data cells, each containing video, audio, and sub-picture data, are arranged Management information of program chains, which are combinations of programs to be reproduced one after another, has been written in a video title set PGC table (VTS_PGCIT). By referring to the program chain table (VTS_PGCIT) according to the user's input, the playback order of program chains can be changed, enabling the program chains to be reproduced one after another in various modes.
