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. When a total size of rendering areas of m windows defined by a WDS (Window Definition Segment) in a display set DSn is denoted by £ SIZE(DSn[WDS].window[i]), presentation time stamps PTS(DSn[PCS]) and PTS(DSn+1 [PCS]) satisfy a relation PTS(DSn[PCS]) + (90000 x £SIZE(DSn[WDS].window[i])) //256,000,000 ‰ PTS(DSn+1[PCS]).
