REPRODUCING DEVICE AND REPRODUCING METHOD, PROGRAM, AND DATA STRUCTURE

摘要

PROBLEM TO BE SOLVED: To allow an audio stream of dual_mono to be added as an object for switching operation for the audio in reproducing an AV stream file. SOLUTION: A controller 34 acquires a playlist for managing the reproduction of the AV stream file containing at least one or more audio streams. When information indicating that the designated audio stream of the dual_mono is included in its playlist, reads the designated audio stream from a storage drive 31 and supplies it to an AV decoder part 33. The AV decoder part 33 outputs what designated by a user among channel1 and channel2 for the supplied designated audio stream as an audio signal. This invention can be applied to the optical disk device capable of at least either of reproducing or recording. COPYRIGHT: (C)2007,JPO&INPIT
