Abstract

Disclosed herein is a data generating device including: a coding section coding a plurality of kinds of data, and generating coded data; an information generating section generating a plurality of pieces of group information indicating combinations of a plurality of kinds of the data; and a file generating section generating a coded data storage file including the coded data of the plurality of kinds of the data and the plurality of pieces of the group information.

1 . A data generating device comprising:
 circuitry configured to:
 store a plurality of kinds of coded data, each kind of coded data corresponding to an individual track of audio/video (A/V) content; and 
 generate a plurality of pieces of group information and metadata corresponding to each of the plurality of pieces of group information, each piece of group information identifying a combination of the individual tracks of the A/V content, wherein 
   the individual tracks of the A/V content include at least a main image track, a secondary image track, a first audio track and a second audio track, and   the circuitry is configured to generate a first piece of group information identifying a combination of at least the main image track and the first audio track, and generate a second piece of group information identifying a combination of the main image track, the secondary image track and the second audio track.   
     
     
         2 . The data generating device according to  claim 1 , wherein
 the coded data forms part of an MP4 file, and   the plurality of pieces of group information are included a movie box of the MP4 file.   
     
     
         3 . The data generating device according to  claim 1 , wherein
 the plurality of kinds of coded data are image data of a main image, image data of a secondary image, and audio data.   
     
     
         4 . The data generating device according to  claim 1 , wherein
 the plurality of kinds of coded data are image data of a three-dimensional main image, image data of a three-dimensional secondary image, and audio data.   
     
     
         5 . A data generating method executed by a data generating device comprising:
 storing a plurality of kinds of coded data, each kind of coded data corresponding to an individual track of audio/video (A/V) content; and   generating a plurality of pieces of group information and metadata corresponding to each of the plurality of pieces of group information, each piece of group information identifying a combination of the individual tracks of the A/V content, wherein   the individual tracks of the A/V content include at least a main image track, a secondary image track, a first audio track and a second audio track, and   the generating the plurality of pieces of group information includes generating a first piece of group information identifying a combination of at least the main image track and the first audio track, and generating a second piece of group information identifying a combination of the main image track, the secondary image track and the second audio track.   
     
     
         6 . A non-transitory computer-readable medium including computer program instruction, which when executed by a data generating device, causes the data generating device to:
 store a plurality of kinds of coded data, each kind of coded data corresponding to an individual track of audio/video (A/V) content; and   generate a plurality of pieces of group information and metadata corresponding to each of the plurality of pieces of group information, each piece of group information identifying a combination of the individual tracks of the A/V content, wherein   the individual tracks of the A/V content include at least a main image track, a secondary image track, a first audio track and a second audio track, and   the generating the plurality of pieces of group information includes generating a first piece of group information identifying a combination of at least the main image track and the first audio track, and generating a second piece of group information identifying a combination of the main image track, the secondary image track and the second audio track.
