Abstract

An audio object for background comprising at least one elementary audio object is recorded in an information storage medium. The playback range in the audio object is designated by designating an elementary audio object number.

Description

technical field [0001] The present invention relates to an information storage medium (or an information recording medium), an information reproducing device and an information reproducing method. Background technique [0002] As such an information storage medium, there has been an optical disc called a digital versatile disc (DVD) capable of reproducing digital information by using focused light. Current DVD specifications include read-only DVD-ROM specification, write-once DVD-R specification, rewritable (about 10,000 times) DVD-RW specification, and rewritable (about 10,000 times or more) DVD -RAW specification. Any technical specification has a format specification, and any format specification defines a format that is recorded on the optical disc itself (information storage medium) of video information (video data, sub-picture data, and audio data, usually called video objects). A data structure, and a data structure of management data for managing video information....
