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 non-transitory recording medium having an interactive graphics stream recorded thereon, wherein

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

each of the object definition segments include a graphics object,

the interactive control segment includes a plurality of button information composing a graphical user interface (GUI),

each of the plurality of button information includes a button number, numeric selection permission information, upper-lower-left-right button information and state information,

the button number is a numerical value identifying button information,

the state information indicates plural states of the button information,

the plural states of the button information include a selected state, an activated state, and a normal state,

the numeric selection permission information indicates whether or not the selected state is permitted to be set for the button number corresponding to a numerical value inputted by a user, and

the upper-lower-left-right button information indicates the button number of button information to be in the selected state relative to one of up, down, left and right directions being inputted by the user.

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

a plane memory;

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

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

when the receiving unit receives the key input specifying one of the up, down, left, and right directions, the graphics decoder sets a corresponding one of the button information 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 value input, the graphics decoder sets a corresponding one of the button information that is identified by the button number matching the input numerical value to the selected state in the GUI.

3. A method for recording onto a non-transitory recording medium, the method comprising:

generating application data using an authoring device; and

recording the application data onto the recording medium, wherein;

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

each of the object definition segments include a graphics object,

the interactive control segment includes a plurality of button information composing a graphical user interface (GUI),

each of the plurality of button information includes a button number, numeric selection permission information, upper-lower-left-right button information and state information,

the button number is a numerical value identifying button information,

the state information indicates plural states of the button information,

the plural states of the button information include a selected state, an activated state, and a normal state,

the numeric selection permission information indicates whether or not the selected state is permitted to be set for the button number corresponding to a numerical value inputted by a user, and

the upper-lower-left-right button information indicates the button number of button information to be in the selected state relative to one of up, down, left and right directions being inputted by the user.
