Abstract

A storage medium storing: video data; and graphics data for displaying a menu. The graphics data includes first graphics data displayed on the screen when an activation command is generated by a user and may also include second graphics data displayed on the screen at a designated time.

Claims

1. A storage medium comprising:

video data; and

graphics data for displaying a menu,

wherein the graphics data includes first graphics data displayed on the screen when an activation command is generated by a user.

2. The storage medium of claim 1, wherein the graphics data also includes second graphics data displayed on the screen at a designated time.

3. The storage medium of claim 2, wherein the first graphics data and the second graphics data have similar or identical structures which include a field for discriminating the first graphics data and the second graphics data.

4. The storage medium of claim 3, wherein the first graphics data and the second graphics data have graphics_segment structures which include segment_type fields defining the type of the first graphics data and the type of the second graphics data, respectively.

5. The storage medium of claim 3, wherein the first graphics data and the second graphics data have interactive_graphic_segment structures which include a type field for discriminating the first graphics data and the second graphics data.

6. The storage medium of claim 2, wherein the first graphics data has an on_demand_interactive_graphic structure different from the structure of the second graphics data.

7. The storage medium of claim 6, wherein the on_demand_interactive_graphic structure includes information regarding an initial menu page indicating that the first graphics data is decoded and ready to be displayed and information regarding at least one menu page to be displayed when an activation command is generated by the user.

8. The storage medium of claim 7, wherein each menu page includes information for displaying at least one button and information regarding a command to be performed when the user selects the button.

9. The storage medium of claim 1, wherein the first graphics data is multiplexed with the video data and recorded in a single stream.

10. The storage medium of claim 2, wherein the first graphics data and the second graphics data are multiplexed with the video data and recorded in a single stream.

11. The storage medium of claim 2, wherein the first graphics data and the second graphics data are multiplexed with the video data and recorded in a single stream, and object data used by the first graphics data indicates an image of the menu screen and is included in an independent stream.
