Abstract
A system for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk. The switching master M&E track. Individual audio tracks are provided for language-specific specific versions of the same motion picture, but these tracks have data recorded in versions of the same motion picture, but these tracks have data recorded in them only where there is dialog. In this way, for many a motion picture, all tracks but masters will have data recorded for well less than haft of the running time of the motion picture. When a mixing master is used, it is mixed with a language-specific track when the latter has dialog; the mixing master contains no dialog. If a switching master is used, it may contain dialog recorded with the M&E; when a language-specific track has dialog recorded in it, it also contains M&E and the track is played to the exclusion of the switching master.
