Abstract
A multimedia optical disc is provided. The multimedia optical disc includes a data area and a management information area. The data area stores a plurality pieces of video data. The management information area stores a channel table in which a plurality of logical channel numbers are respectively related to a plurality of physical channel numbers for each piece of video data. A piece of moving picture data and a plurality pieces of sub-data are interleaved in each piece of video data. The sub-data is either of audio data and sub-picture data as still pictures. The logical channel numbers are shared by pieces of video data. The physical channel numbers are used to physically identify the plurality pieces of sub-data. With this construction, it is possible to manage sub-data even when the sub-data is dealt with by a plurality pieces of video data.
