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 reproducing apparatus for reproducing data from a storage medium, the apparatus comprising:

a reading unit configured to read a video stream comprising video data and an interactive graphics stream comprising graphics data for displaying a menu on a screen, from the storage medium;

a video decoder configured to decode the video data;

a graphics decoder configured to decode the graphics data;

a blender configured to overlay the decoded graphics data on the decoded video data;

an interface configured to transmit a user command to the graphics decoder; and

a register configured to store a stream number of the graphics data to be reproduced,

wherein the graphics data comprises a field indicating whether the graphics data is first graphics data or second graphics data,

wherein the graphics decoder is further configured to decode the first graphics data to be displayed when an activation command is received, and to decode the second graphics data to be displayed at a time designated by a presentation time stamp included in a packetized elementary stream carrying the second graphics data, and

wherein the menu disappears from the screen at a time designated by output finish time information included in the graphics data.
