Patent ID: 8433678

Claim:
A reproducing method for reproducing a composite content file in which a plurality of types of media data are multiplexed, the composite content file including a first composite content file to be reproduced first on the time base and a second composite content file to be reproduced continuously next to the first composite content file, the first composite content file and the second composite content file being obtained by dividing, on the time base, each media data contained in the composite content file, each of the first composite content file and the second composite content file being given synchronizing information, the synchronizing information containing information about a position shift on the time base at reproduction start and reproduction end of video data that is one of the media data, the method comprising: obtaining synchronizing information that is given to the first composite content file and the second composite content file; extracting information about a position shift on the time base of each media data among the synchronizing information; and reproducing the first composite content file and the second composite file successively by correcting reproduction time of each media data of the first composite content file and the second composite content file based on the extracted information about a position shift on the time base.
