METHOD FOR INTERLEAVING DATA FOR SEAMLESS PLAYBACK OF MULTIPLE PROGRAM VERSIONS HAVING COMMON MATERIAL

摘要

A method for formatting digital data on an optical disk (23) that represents at least two versions of the same program. Data sequences which are unique to each version and data sequences which are common to the two of them are interleaved in a single data stream (fig. 6). In order to achieve seamless play of both versions on a player (21) that is compatible with the disk format but has limited buffer storage, data which would otherwise be common to both versions is placed redundantly in the data sequences which are unique to both versions.
