摘要

PROBLEM TO BE SOLVED: To provide a recording medium that realizes interactive display with animation, without delay. SOLUTION: A BD-ROM has recorded therein an AV Clip generated by multiplexing a video stream and a graphics stream. The graphics stream includes a sequence of three Button State groups. In the three Button State groups in the graphics stream, the first-order group (N-ODSs) is made of a plurality of pieces of graphics data, which represent normal states of the buttons, the second-order group (S-ODSs) is made of a plurality of pieces of graphics data, which represent selected states of the buttons, and the third-order group (A-ODSs) is made of a plurality of pieces of graphics data, which represent active states of the buttons. Designation information in the initial display of the interactive display indicates that a button member in a selected state as a default is dynamically changed (default_selected_button_number=0).
