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 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.

Claims

1. A system for controlling play of the audio tracks of a software carrier, said software carrier having recorded thereon a plurality of datablocks which represent an image program, a plurality of audio tracks synchronized with said image program, and a code for each of said audio tracks identifying its use as either a switching master including music and effect and dialog language, a mixing master containing only music and effects, a track to be switched with a switching master, or a track to be mixed with a mixing master, comprising means for selecting a switching master of predetermined length and a shorter track containing audio segments to be switched with said switching master, or a mixing master of predetermined length and a shorter track containing audio segments to be mixed with said mixing master, and codes in the data blocks that specify to automatically switch between or mix the selected tracks.

2. The system in accordance with claim 1 wherein said audio track is a digital audio track.

3. The system in accordance with claim 2 including means for processing said audio track codes to determine how said digital audio track signals should be mixed or switched and for deriving an analog audio signal therefrom.

4. The system in accordance with claim 3 including control means for mixing or switching signals derived from said audio track signals in accordance with said audio track codes to derive said analog audio signal synchronized with said image signal.

5. A system in accordance with claim 4 wherein said software carrier has recorded thereon a code for each of said digital audio tracks indicative of the language of any dialog therein, and further including means for selecting a digital audio track to be mixed or switched in accordance with the dialog language desired by a user.

6. A system in accordance with claim 5 wherein said control means switches or mixes a selected digital audio track with a switching master or a mixing master in accordance with the identifying code associated with the selected digital audio track.

7. A system in accordance with claim 4 wherein any switching master digital audio track on said software carrier has associated therewith a switching master identifying code, and any mixing master digital audio track on said software carrier has associated therewith a mixing master identifying code, and further including means for selecting either a switching master digital audio track or a mixing master digital audio track for respective switching or mixing with the selected digital audio track in accordance with the identifying code associated with the selected digital audio track.

8. A system in accordance with claim 7 wherein on said software carrier at least one switching master digital audio track or one mixing master digital audio track includes music and effects.

9. A system in accordance with claim 8 wherein information recorded on said software carrier is recorded in separately identifiable blocks, each software carrier block containing indicia of which digital audio tracks in the block represent a signal, and said control means operates on only the digital audio tracks in any block that are required to derive an analog audio signal in accordance with the dialog language desired by a user and said audio track codes.

10. A system in accordance with claim 9 wherein said software carrier has recorded thereon an identification of the type of each digital audio track, and further including means for processing derived signals in accordance with said track type identifications.

11. A system in accordance with claim 6 wherein said software carrier has recorded thereon a representation of the available dialog languages on the software carrier, and further including means for representing a default language, said means for selecting a digital audio track being operative to select a digital audio track in accordance with the default language which is represented and the available dialog languages on the software carrier.

12. A system in accordance with claim 5 wherein said software carrier has recorded thereon a representation of the available dialog languages on the software carrier, and further including means for representing a default language, said means for selecting a digital audio track being operative to select a digital audio track in accordance with the default language which is represented and the available dialog languages on the software carrier.

13. A system in accordance with claim 12 further including means responsive to said default language matching none of said available languages, for allowing the user to choose an available language.

14. A system in accordance with claim 13 wherein said control means switches or mixes a selected digital audio track with a switching master or a mixing master in accordance with the identifying code associated with the selected digital audio track.

15. A system in accordance with claim 5 wherein any switching master digital audio track on said software carrier has associated therewith a switching master identifying code, and any mixing master digital audio track on said software carrier has associated therewith a mixing master identifying code, and further including means for selecting either a switching master digital audio track or a mixing master digital audio track for respective switching or mixing with the selected digital audio track in accordance with the identifying code associated with the selected digital audio track.

16. A system in accordance with claim 15 wherein on said software carrier at least one switching master digital audio track or one mixing master digital audio track includes music and effects.

17. A system in accordance with claim 5 wherein said software carrier has recorded thereon a code for each of said digital audio tracks indicative of the language of any dialog therein, information recorded on said software carrier is recorded in separately identifiable blocks, each software carrier block contains indicia of which digital audio tracks in the block represent a signal, and said control means operates on only the digital audio tracks in any block that are required to derive said analog audio signal in accordance with the dialog language desired by a user and said audio track codes.

18. A system in accordance with claim 17 wherein said software carrier has recorded thereon an identification of the type of each digital audio track, and further including means for processing derived signals in accordance with said track type identifications.

19. A system in accordance with claim 5 wherein said software carrier has recorded thereon an identification of the type of each digital audio track, and further including means for processing derived signals in accordance with said track type identifications.

20. A system in accordance with claim 1 wherein on said software carrier at least one switching master digital audio track or one mixing master digital audio track includes music and effects.
