Abstract

A storage medium storing multimedia data for the reproduction of audio-visual (AV) data and a programming function, and a reproducing apparatus and method thereof. The storage medium includes: reproduction mode data for reproducing audio-visual (AV) data; program data including a plurality of program applications for providing interactive functions with a user and/or additional functions using the AV data; system data for controlling the execution of the reproduction mode data and the program data; and application objects for managing the execution of the program data and information on the reproduction mode data to be reproduced along with the execution of the program data. Accordingly, various user interfaces and/or various additional functions can be provided, as well as simple reproduction of AV data. Also the program application can be prevented from using malicious intent, and program applications having the same function can be reused without modification or recompilation.

program data including a plurality of program applications, for providing interactive functions with a user and/or additional functions using the AV data;

system data controlling execution of the reproduction mode data and the program data; and

application objects managing the execution of the program data and information on the reproduction mode data to be reproduced along with the execution of the program data.

2. The storage medium of claim 1, wherein each of the application objects includes application management information managing the execution of the program data and playlist information which is a reproduction unit of the reproduction mode data in title units.

3. The storage medium of claim 2, wherein the application management information includes information on attributes of the program data and information on the execution of the program data.

4. The storage medium of claim 3, wherein the information on attributes of the program data includes at least one of location, name and version information of the program applications, and the information on the operation of the program data includes at least one of information on start, pause and end of the program applications, pre-load information, and pre-patch information.

5. The storage medium of claim 1, wherein the program data is an application program written in one of Java, HTML, C, and a scripting language.

6. The storage medium of claim 2, wherein the playlist information includes the file name of at least one playlist reproduced along with the execution of the program data.

22. The storage medium of claim 1, wherein at least one of the application objects comprises additional information including at least one of a title identifier, a title name, and/or a title descriptor intelligible to a user.

23. The storage medium of claim 1, wherein each application object exists in a separate file corresponding to a respective title included in the AV data.

24. The storage medium of claim 1, wherein a plurality of application objects are included in one file and associated with corresponding portions of the AV data using a title identifier.

7. A reproducing apparatus comprising:

a reader which reads application objects from a storage medium, including reproduction mode data reproducing audio-visual (AV) data, program data including a plurality of program applications providing interactive functions with a user and/or additional functions using the AV data, system data controlling the execution of the reproduction mode data and the program data, and application objects managing the execution of the program data and information on the reproduction mode data to be reproduced along with the execution of the program data; and

a controller which manages execution of the program data based on the read application objects in title units.

8. The apparatus of claim 7, further comprising:

an application manager which controls reproduction of the reproduction mode data and the execution of the program data based on the application objects.

9. The apparatus of claim 8, wherein each of the application objects includes application management information managing execution of the program data and playlist information which is a reproduction unit of the reproduction mode data in title units, and

the application manager controls the operation of the program applications based on the application management information, and reproduces AV data corresponding to the program applications along with the execution of the program applications based on the playlist information.

10. A reproducing method comprising:

reading application objects from a storage medium, including reproduction mode data reproducing audio-visual (AV) data, program data including a plurality of program applications providing interactive functions with a user and/or additional functions using the AV data, system data controlling the execution of the reproduction mode data and the program data, and application objects managing execution of the program data and information on the reproduction mode data to be reproduced along with the execution of the program data; and

managing the execution of the program data based on the application objects in title units.

11. The method of claim 10, further comprising:

controlling reproduction of the reproduction mode data and the execution of the program data based on the application objects.

12. The method of claim 11, wherein each of the application objects includes application management information managing the execution of the program data and playlist information which is a reproduction unit of the reproduction mode data in title units, and

in the controlling of the reproduction of the reproduction mode data and the execution of the program data, the operation of the program applications is controlled based on the application management information, and AV data corresponding to the program applications is reproduced along with the execution of the program applications based on the playlist information.

13. The method of claim 12, wherein the controlling of the reproduction of the reproduction mode data and the execution of the program data comprises:

confirming a title selected from an index table included in the system data;

confirming playlist information and application management information if the confirmed title is full mode data;

reading a relevant playlist file from the reproduction mode data based on the confirmed playlist information; and

reproducing AV data based on the playlist file read during the execution of a relevant program application from the program data, based on the confirmed application management information.

14. A method of interactively relating supplemental information to moving picture data, the method comprising:

reproducing a moving picture based on the moving picture data;

providing a program application by which the supplemental information is linkable to the motion picture data during the reproduction of the moving picture data;

providing a user with a pointing device for indicating a portion of the moving picture; and

displaying the supplemental information related to an object indicated by the user during the reproducing of the motion picture.

15. The method of claim 14, wherein the supplemental information is advertising information about the indicated object.

16. The method of claim 14, wherein the supplemental information is geographical information about the indicated object.

17. The method of claim 14, wherein the indicated object is an actor in the movie and the supplemental information is biographical or current information about the actor.

18. The method of claim 14, further comprising:

providing the moving picture data and the supplemental information from a same storage medium.

19. The method of claim 18, wherein the same storage medium is one of a magnetic storage medium, an optical recording medium, and a carrier wave medium.

20. The method of claim 14, further comprising:

providing the moving picture data and the supplemental information from different storage media.
