摘要 |
A multimedia optical disc for recording main video data which is composed of sets of frame data that is processed beforehand to enable display at an aspect ratio specified out of a plurality of aspect ratios. The disc has a stream area storing streams made up of the main video data and a plurality of sets of sub-picture data, with each set of sub-picture data including a set of tel-op data and a set of coordinate information showing a display position of the set of tel-op data. The disc also includes a control area storing a plurality of pairings of a set of display mode information and a set of sub-picture indicating information. Each set of display mode information shows a species of display method according to which the frame data is to be processed for a case when the frame data decoded from the main video data is displayed at one of the plurality of aspect ratios. Each set of sub-picture indicating information shows a set of sub-picture data, out of the plurality of sets of sub-picture data in a same stream as the main video data, which includes a set of coordinate information which coincides with the species of display method shown by the display mode information. <IMAGE> |
