摘要:
An AV Clip formed by multiplexing a video stream and a graphics stream and recorded on a BD-ROM as a recording medium. The video stream constitutes a moving picture while the graphics stream enables graphics to be overlaid on the moving picture, and includes pieces of control information called a PCS and an ICS. When the AV Clip is played back immediately following playback of another digital stream, the control information indicates to the reproduction device that the presence of data already in memory of a graphics decoder is to be continuous.

A plurality of video streams and STN_table are recorded in the local storage 200. Each of the plurality of video streams is a secondary video stream to be played together with a primary video stream, and includes picture data representing a child image to be displayed in Picture in Picture that is composed of a parent image and the child image. In the STN_table, entries of secondary video streams that are permitted to be played are described in the order of priority.

An AV Clip generated by multiplexing video and graphics streams is recorded on a BD-ROM. The graphics stream includes an interactive graphics stream. PTS(DSn[ICS]), which is a presentation time stamp of a packet containing an ICS (Interactive Composition Segment) in a n-th display set DSn, designates an end time of an active period of the ICS, and DTS(DSn+1[ICS]), which is a decoding time stamp of a packet containing an ICS in an immediately succeeding display set DSn+1, designates a start time of an active period of the ICS. PTS(DSn[ICS]) and DTS(DSn+1[ICS]) satisfy a relation PTS(DSn[ICS])≦DTS(DSn+1[ICS]).

A BD-ROM contains an AVClip in which a video stream is multiplexed with an interactive graphics stream. The video stream constitutes a moving picture. On the other hand, the graphics stream constitutes menu presentations to be combined with a moving picture. The graphics stream includes a plurality of display sets constituting the menu presentations. Each of the display sets has interactive control information (ICS). Among the display sets belonging to the graphics stream, the interactive control information (ICS) other than the one belonging to the head one include version information (page_version_number) indicating whether or not content of the menu presentation has changed with respect to the previous Display Set.

AVClip recorded in BD-ROM is obtained by multiplexing a graphics stream and a video stream. The graphics stream is a PES packet sequence that includes 1) PES packets storing graphics data (ODS) and 2) PES packets storing control information (PCS). In each ODS, values of DTS and PTS indicate a timing of decoding start for corresponding graphics data, and a timing of decoding end for corresponding graphics data, respectively. In each PCS, a value of PTS indicates a display timing of corresponding decoded graphics data combined with the video stream.

An AV Clip generated by multiplexing video and graphics streams is recorded on a BD-ROM. The graphics stream includes a plurality of DSs (Display Sets) which are each a group of segments used for graphics display. ODSs (Object Definition segments) belonging to a DS include a referenced ODS and a non-referenced ODS. The non-referenced ODS is an ODS that is not referenced by a PCS (Presentation Composition Segment) included in the display set. An END segment is provided immediately following a last ODS of the sequence of the referenced ODS and the non-referenced ODS in the display set.
