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,

wherein the first graphics data and the second graphics data have an interactive composition segment structure which includes a type field, and

the type field is defined so that, when a value of the type field is a first value, the second graphics data is indicated, and when a value of the type field is a second value, the first graphics data is indicated, the first value for the type field corresponding to a normal interactive graphics stream and the second value for the type field corresponding to an on-demand interactive graphics stream.

2. The reproducing method of claim 1, wherein the type field comprises a binary data field.
