Abstract

A recording medium, method and apparatus for managing data are discussed. According to an embodiment, the present invention provides a method of reproducing main data and additional data. The method includes receiving the additional data associated with the main data, the additional data being divided into a plurality of segment units; and reproducing the additional data in a synchronous manner with the main data using time information if indication information indicates a presence of the time information. The time information indicates a presentation time of the additional data with respect to the main data. The main data and the additional data are reproduced according to management data, the management data including link information for linking the main data and the additional data.

Claims

1. A method of reproducing main data and additional data, the method comprising:

receiving the additional data associated with the main data, the additional data being divided into a plurality of segment units; and

reproducing the additional data in a synchronous manner with the main data using time information when indication information indicates a presence of the time information,

wherein the time information indicates a presentation time of the additional data with respect to the main data,

wherein the main data and the additional data are reproduced according to management data, the management data including link information for linking the main data and the additional data, and

wherein the link information is separately stored from the main data and the additional data,

whereby the additional data can be affectively reproduced with the main data in a synchronous manner.

2. The method of claim 1, wherein the main data and the additional data are provided separately, and the reproducing step reads the additional data and the main data separately and controls a synchronization of the additional data with respect to the main data using the time information.

3. The method of claim 2, wherein the indication information is provided separately from the main data and the additional data.

4. The method of claim 1, wherein each segment unit includes a corresponding time information, and the reproducing step reproduces each segment unit using the corresponding time information.

5. The method of claim 1, wherein each segment unit includes type information to indicate a type of the additional information, and the reproducing step reproduces each segment unit according to the type information.

6. The method of claim 1, wherein each segment unit includes type information to indicate a type of the time information, and the reproducing step reproduces each segment unit according to the type information.

7. The method of claim 6, wherein the type information indicates one of a start time or a duration time of the corresponding segment unit.

8. The method of claim 1, wherein the link information excludes a web address.

9. A method of reproducing main data and additional data, the method comprising:

providing the additional data associated with the main data, the additional data being divided into a plurality of segment units; and

reproducing the additional data in a synchronous manner to the main data using time information when indication information indicates a presence of the time information,

wherein the time information is present only when the indication information indicates that the time information is present,

wherein the main data and the additional data are reproduced according to link information for linking the main data and the additional data, and

wherein the link information is separately stored from the main data and the additional data,

whereby the additional data can be affectively reproduced with the main data in a synchronous manner.

10. The method of claim 9, wherein the indication information is provided separately from the main data and the additional data, and the reproducing step further includes reading the indication information separately and identifying whether the time information is present based on the indication information.

11. The method of claim 9, wherein the link information excludes a web address.

12. A method of reproducing main data and additional data, the method comprising:

retrieving the additional data associated with the main data, the additional data being divided into a plurality of segment units; and

reproducing the additional data in a synchronous manner to the main data using time information, the time information being used to synchronize the additional data with the main data,

wherein the additional data is reproduced according to management information, the management information including the time information, format information to indicate a format of the additional data, and link information for linking the main data and the additional data, and

wherein the management information is provided separately from the main data and the additional data and includes indication information to identify whether the time information is present,

whereby the additional data can be affectively reproduced with the main data in a synchronous manner.

13. The method of claim 12, wherein the reproducing step includes identifying whether the time information is present based on the indication information, reading the time information if the time information is present, and reproducing the additional data in the synchronous manner to the main data using the read time information.

14. The method of claim 12, wherein the format information indicates whether the additional data is lyric data or user-defined data.

15. The method of claim 12, wherein the management information further includes a start address, size information and attribute information of each of the segment units.

16. The method of claim 12, wherein the link information excludes a web address.

17. A method of providing additional data to be reproduced with main data, the method comprising:

providing the additional data associated with the main data, the additional data being divided into a plurality of segment units and capable of being reproduced with the main data in a synchronous manner; and

providing management information associated with the additional data,

wherein the management information includes link information for linking the main data and the additional data, time information for reproducing the additional data with the main data in the synchronous manner, and attribute information for providing at least one attribute of the additional data, and

wherein the management information further includes indication information indicating a presence of the time information,

whereby the additional data can be affectively reproduced with the main data in a synchronous manner.

18. The method of claim 17, wherein the link information excludes a web address.

19. A method of providing additional data to be reproduced with main data, the method comprising:

providing the additional data associated with the main data, the additional data being divided into a plurality of segment units and capable of being reproduced with the main data in a synchronous manner; and

providing management information associated with the additional data,

wherein the management information includes time information and indication information indicating a presence of the time information, the time information being present only when the indicating information indicates the time information is present,

wherein the management information further includes linking information for linking the main data and the additional data, and

wherein the additional data is provided separately from the main data,

wherein the management information further includes indication information indicatin a presence of the time information.

20. The method of claim 19, wherein the time information indicates a presentation start time or a presentation duration time of the additional data.

21. The method of claim 19, wherein each segment unit includes a corresponding time information.

22. The method of claim 19, wherein the management information is provided separately from the main data and the additional data.

23. The method of claim 19, wherein the link information excludes a web address.
