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, andthe 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.
