摘要:
For the reproduction of data recorded on an information recording medium using an audio/video format that includes a plurality of audio streams, arranged so they may be performed during the same period of time, and an audio menu by which user selection of these audio streams is enabled, the state wherein an arbitrary audio stream is being reproduced is shifted directly to an audio menu display state (S110), and when an audio stream selection is made by a user, reproduction is resumed beginning at the reproduction position extant immediately before the audio menu was displayed. Thus, even when an audio menu is not displayed, a user is permitted to directly designate an arbitrary audio stream.
