Abstract
An AV Clip generated by multiplexing video and graphics streams is recorded on a BD-ROM. The graphics stream is a sequence of PES packets. The PES packets include ODSs (Object Definition Segments) carrying graphics data and PCSs (Presentation Control Segments) carrying control information. A PCS indicates that graphics data in a preceding ODS in the arrangement is to be displayed at a predetermined time in a state of being overlaid on the video stream. The PCS and the preceding ODS belong to different DSs, and the graphics data in the preceding ODS may be non-referenced graphics data that is not referenced by a PCS which belongs to the same DS as the preceding ODS.

16. A system LSI for reproducing a digital stream generated by multiplexing a video stream and a graphics stream, comprising:
-
a video decoder operable to decode the video stream to generate a moving picture; and
;
a graphic decoder operable to decode the graphics stream to generate graphics, and overlay the graphics and the moving picture, wherein upon reading control information in the graphics stream, the graphics decoder displays graphics which has been generated by decoding graphics data that precedes the control information in the graphics stream, based on the control information. - View Dependent Claims (17, 18)
