Abstract

A method of reproducing from a storage medium video data and graphics data for displaying a menu screen. The method includes: decoding graphics data; and outputting, on the basis of the decoded graphics data, the decoded graphics data when an activation command is generated by a user or displaying the decoded graphics data at a designated time.

Claims

1. A reproducing method of reproducing from a storage medium video data and graphics data for displaying a menu screen, comprising:

decoding graphics data;

outputting the decoded graphics data when an activation command is generated by a user and the decoded graphics data is first graphics data; and

outputting the decoded graphics data at a designated time when the decoded graphics data is second graphics data.

2. The reproducing method of claim 1, wherein the first graphics data and the second graphics data have an identical or similar structure which includes a field for individually identifying and discriminating between the first graphics data and the second graphics data.

3. The reproducing method of claim 2, wherein the first graphics data and the second graphics data have a graphics_segment structure which includes a segment_type field defining the type of the first graphics data and the type of the second graphics data, respectively.

4. The reproducing method of claim 2, wherein the first graphics data and the second graphics data have an interactive_graphic_segment structure which includes a type field for individually identifying and discriminating between the first graphics data and the second graphics data.

5. The reproducing method of claim 4, wherein the type field is defined so that, when a value of the type field is 0, the second graphics data is indicated, and when a value of the type field is 1, the first graphics data is indicated.
