Abstract
A BD-ROM has recorded therein an AV Clip generated by multiplexing a video stream and a graphics stream. The graphics stream represents an interactive display to be overlayed with the video stream, and includes a sequence of three Button State groups. The interactive display includes a plurality of buttons, each of which changes from a normal state to a selected state, and from the selected state to an active state, according to a user operation. 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.

12. A system LSI for decoding a graphics stream, said system LSI comprising:
-
a graphics decoder operable to decode the graphics stream which represents an interactive display including a plurality of graphical button materials to be overlayed with a motion picture, wherein;
the graphics stream includes a plurality of graphics data sets each forming a group of graphics data which renders a predetermined state of the graphical button materials;
the plurality of graphics data sets respectively renders different predetermined states of the graphical button materials and are disposed in a sequential order of displaying the different predetermined states; and
said graphics decoder uses the graphics data respectively belonging to a top set and a second-place set in the plurality of graphics data sets for presenting an initial display of the interactive display, and uses the graphics data belonging to remaining ones of the plurality of graphics data sets for updating the interactive display upon a user operation. - View Dependent Claims (13, 14, 15)
