On a BD-ROM, there is recorded is a digital stream into which video and audio streams are multiplexed. The video stream is composed of a plurality of pictures that together represent video. The graphics stream includes a PES packet storing state control information (ICS) and PES packets containing graphics data (ODSs). The graphics data constructs an interactive display. The state control information defines the control so as to change the states of buttons presented on the interactive display according to the reproduction proceeding and user operations.The ICS is attached with a PTS showing the display timing of a picture to be synchronized with the interactive display. The ODS is attached with a PTS showing the timing for decoding the graphics data. The timing shown in the ODS is prior to the display timing.

An AVClip, and a PLMark specifying a playback start position in the AVCLip, are recorded on a BD-ROM. A cue-up operation for choosing a playback start position in the AVClip is performed by three types of instructions, namely a user-skip operation, a chapter search operation, and a Link command.Among these three types of instructions, attribute information included in marker information indicates whether only a branching command operation is allowed for choosing a corresponding playback start position, or the user-skip operation and the chapter search operation are allowed adding to the branching command.

A BD-ROM 100 for causing a playback device to display a menu while displaying a moving image as a background of the menu. The BD-ROM 100 includes one or more AVClips constituting the moving image; a BD-J Object that causes the playback device to perform an operation wait control to wait for an operation to be conducted via the displayed menu; and PlayList information. The PlayList information includes a sequence composed of 999 pieces of PlayItem information each of which corresponds to one of the one or more AVClips and instructs the playback device to repeat a playback of the corresponding AVClip 999 times.

On a BD-ROM, an AVClip and a plurality of playback section information (PlayItems) are recorded. The AVClip includes a video stream multiplexed with a plurality of elementary streams. The playback section information Playable_PID_entries showing the playback start point and the playback end point in the video stream correlated with the filtering specification of each elementary stream. The filtering specification specifies whether each of the plurality of elementary streams are able to be played back or not.

When reading an AV Clip which is formed by multiplexing a plurality of elementary streams from a BD-ROM and playing back the AV Clip, an STN_table that lists an entry of each elementary stream is acquired from PlayList information on the BD-ROM. For each elementary stream shown in the STN_table, a judgment is made as to whether the elementary stream satisfies a predetermined condition. Of all elementary streams judged as satisfying the predetermined condition, an elementary stream having a highest entry in the STN_table is selected and played back.

An optical disk includes an audio data storage area for storing audio data; a still picture data storage area for storing a plurality of pieces of still picture data; and a management area for storing reproduction control information for controlling reproduction of the audio data and the plurality of pieces of still picture data. The reproduction control information has flag information representing specified still picture data among the plurality of pieces of still picture data.

An optical disc, as an information recording medium for storing map audio object recorded on the optical disc in a constant bit rate format or a variable bit rate format and a recording position on the disc, can reduce a size of the map information. The map information stored in the optical disc records a playback duration for only first and last units of a plurality of audio object units (AOBU) comprised in an audio object (AOB) for each AOB when audio data in the variable bit rate mode is to be recorded, and records the sizes and playback duration of the AOBU for the last one of AOBUs comprised in AOB and for any one of the AOBUs except for the last AOBU.

The present invention provides a bitstream generation apparatus that enables an efficient editing of video objects in providing a finished audio video production. Audio and video data is encoded and an elementary encode unit correlates the audio and video data into video objects. The video objects can be assembled by an editing unit into a desired scenario of reproduction. An editor can re-arrange the scenes that are formed by the video objects with the assistance of a correction unit and an interleaving unit that can divide the pieces of audio data and the pieces of video data that form the video objects into new video objects which can be interleaved into the reproduction order of video objects without requiring a re-encoding of the entire set of video objects that constitute sequences of scenes for the audio video product.

An audio object (AOB) for which corresponding rights management information (RMI) has been generated by a license management apparatus, and an AOB for which RMI does not exist are written into a recording medium for use in an SDMI system which includes the license management apparatus. Each AOB is put in correspondence with a migration permission flag (MPF). When the corresponding AOB is the AOB for which RMI does not exist, the relevant MPF is set to on so as to show that a migration procedure is permitted. When the corresponding AOB is the AOB for which RMI has been generated by the license management apparatus, the relevant MPF is set to off so as to show that a migration procedure is not permitted.
