Abstract

When moving pictures are recorded onto an optical disc, not only is text data recorded, but also video-recording start date and time, video-recording end date and time, and source name or channel number serving as primary text data are recorded in alphanumeric characters program by program or cell by cell, a program or a cell being used as a unit of video-recording. Other text data is recorded together with language code. Since the primary text data used to select video data is expressed in alphanumeric characters, a program or cell to be reproduced can be selected, regardless of language, and the text information in the same language as that of the apparatus can be searched for.
