Abstract

In the data structure for managing reproduction of text subtitle data, a recording area stores graphic control information indicating whether to still a display of main data when a display of graphic information is activated.

Claims

1. A recording medium having a data structure for managing graphic information, comprising:

a recording area storing graphic control information indicating whether to still a display of main data when a display of graphic information is activated.

2. The recording medium of claim 1, wherein the graphic information is a menu.

3. The recording medium of claim 1, wherein the activation of the display of graphic information is based on user input.

4. The recording medium of claim 1, wherein the graphic control information further indicates whether display of the graphic information is forbidden.

5. The recording medium of claim 4, wherein the graphic information is a menu.

6. The recording medium of claim 1, wherein the graphic control information further includes mask information indicating whether display of the graphic information is forbidden.

7. The recording medium of claim 6, wherein the mask information is stored in a playlist file on the recording medium.

8. The recording medium of claim 7, wherein the mask information is stored in an application information playlist field of the playlist file.

9. The recording medium of claim 1, wherein the recording area stores a playitem in a playlist, and the playitem includes navigation information for reproducing the graphic information from a clip file.

10. The recording medium of claim 9, wherein the recording medium stores the graphic information multiplexed with the main data in the clip file.

11. The recording medium of claim 9, wherein the graphic information is a menu.

12. The recording medium of claim 1, wherein the recording area stores a subplayitem in a playlist, and the subplayitem includes navigation information for reproducing the graphic information from a clip file.

13. The recording medium of claim 12, wherein the recording area stores a playitem in the playlist, and the playitem includes navigation information for reproducing main data from a clip file separate from the clip file having the graphic information.

14. The recording medium of claim 12, wherein the graphic information is a menu.

15. A recording medium having a data structure for managing graphic information, comprising:

a recording area storing graphic information for display and storing mask information indicating whether display of the graphic information is forbidden.

16. The recording medium of claim 15, wherein the graphic information is a menu.

17. The recording medium of claim 15, wherein the recording area stores graphic information for display based on user input.

18. The recording medium of claim 17, wherein the graphic information is a menu.

19. The recording medium of claim 15, wherein the mask information is stored in a playlist file on the recording medium.

20. The recording medium of claim 19, wherein the mask information is stored in an application information playlist field of the playlist file.

21. The recording medium of claim 15, wherein the recording area stores a playitem in a playlist, and the playitem includes navigation information for reproducing the graphic information from a clip file.

22. The recording medium of claim 21, wherein the recording medium stores the graphic information multiplexed with main data in the clip file.

23. The recording medium of claim 22, wherein the graphic information is a menu.

24. The recording medium of claim 15, wherein the recording area stores a subplayitem in a playlist, and the subplayitem includes navigation information for reproducing the graphic information from a clip file.

25. The recording medium of claim 24, wherein the recording area stores a playitem in the playlist, and the playitem includes navigation information for reproducing main data from a clip file separate from the clip file having the graphic information.

26. The recording medium of claim 24, wherein the graphic information is a menu.

27. A method of reproducing graphic information from a recording medium, comprising:

reproducing graphic control information from the recording medium, the graphic control information indicating whether to still a display of main data when a display of graphic information is activated; and

stilling a display of the main data when a display of the graphic information is activated and the graphic control information indicates to still the display of main data; and

reproducing the graphic information when the display of the graphic information is activated.

28. A method of recording a data structure for managing reproduction of graphic information on a recording medium, comprising:

recording graphic control information on the recording medium, the graphic control information indicating whether to still a display of main data when a display of graphic information is activated.

29. An apparatus for reproducing graphic information from a recording medium, comprising:

a driver for driving an optical reproducing device to reproduce data recorded on the recording medium;

a controller for controlling the driver to reproduce graphic control information from the recording medium, the graphic control information indicating whether to still a display of main data when a display of graphic information is activated;

the controller stilling a display of the main data when a display of the graphic information is activated and the graphic control information indicates to still the display of main data; and

the controller controlling the driver to reproduce the graphic information when the display of the graphic information is activated.

30. An apparatus for recording a data structure for managing reproduction of a text subtitle data, comprising:

a driver for driving an optical recording device to record data on the recording medium;

a controller for controlling the driver to record graphic control information on the recording medium, the graphic control information indicating whether to still a display of main data when a display of graphic information is activated.
