A system for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk. The optical disk has encoded on it a mixing master music and effects (“M&E”) track, or a switching master M&E track Individual audio tracks are provided for language-specific 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 half 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.
A data stream, to be processed by a compatible system that operates on bits at a constant bit rate, for representing a plurality of different-type signals synchronized with each other, said different-type signals being represented in the data stream in the form of digital data, characterized in that each of said different-type signals is represented by a bit stream designed to be processed at a bit-use rate which varies with the information content of the signal itself and with the bit-use rates for said plurality of different-type signals being independent of each other, the digital data being organized in a series of data blocks among which are data blocks containing different numbers of bits in respective ones of multiple bit streams, the bit streams being distributed among the data blocks such that bits of each bit stream, after being operated upon and buffered by a compatible system, are at all times available for use as required for proper reconstruction of the respective represented signal.
A set of data embodied on a machine-readable medium or in a data stream for representing a plurality of different-type signals synchronized with each other, each of said different-type signals being represented by a bit sequence designed to be processed by a compatible system at a bit-use rate which varies with the information content of the signal itself and with the bit-use rates for said plurality of different-type signals being independent of each other, the data being organized in a series of data blocks among which are data blocks containing different numbers of bits in respective ones of multiple bit sequences, the bit sequences being distributed among the data blocks such that bits of each bit sequence, after being operated upon and buffered by a compatible system, are at all times available for use as required for proper reconstruction of the respective represented signal.
