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.

Claims

1. A recording medium having an interactive graphics stream recorded thereon, wherein

the interactive graphics stream includes an interactive control segment and object definition segments,

each object definition segment is a functional segment defining a graphics object,

the interactive control segment includes numeric selection permission information, upper-lower-left-right button information and state information, the state information indicates, for each of a plurality of button materials composing a GUI, an object definition segment defining a graphics object to be displayed as one state of the button material,

the numeric selection permission information indicates, for each button material composing the GUI, whether or not the button material is permitted to be set in a selected state in response to a numerical input of a corresponding button number, and

the upper-lower-left-right button information indicates, for each button material composing the GUI and for each of up, down, left and right directions relative to the button material, a button number identifying one of the button materials to be set in a selected state in response to a key input specifying a corresponding one of the up, down, left and right directions.

2. A reproduction apparatus for reading and reproducing the interactive graphics stream from the recording medium as defined in claim 1, said reproduction apparatus comprising:

a plane memory;

a graphics decoder operable to decode object definition segments included in the interactive graphics stream and writing graphics objects on the plane memory thereby to compose a GUI that includes a plurality of button materials;

a receiving unit operable to receive a key input made by a user, wherein

when the receiving unit receives a key input specifying one of the up, down, left, and right directions, the graphics decoder sets a corresponding one of the button materials that is identified by the upper-lower-left-right button information to a selected state in the GUI, and

when the receiving unit receives a numerical key input, the graphics decoder sets a corresponding one of the button materials that is identified by a button number matching the input numeral to a selected state in the GUI.
