摘要

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 used for graphics display. The DS includes graphics data and a control segment that includes time stamps (DTS and PTS) for designating an active period of the control segment in the DS on a reproduction time axis of the video stream. When the active period of the control segment in the DS overlaps with an active period of a control segment in an immediately preceding DS, the time stamps designate the active period of the control segment in the DS to start at or after a time at which, during the active period of the control segment in the immediately preceding DS, transfer of graphics generated by decoding graphics data in the immediately preceding DS to an Object Buffer is completed.
