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 for providing a describing data associated with a main data, the method comprising:

retrieving, by one or more processors, describing data, linking information, indication information, still video location information, and format information,

wherein the still video location information indicates a location of the still video data and corresponds to still video location index information;

associating, using the linking information, the main data with the describing data;

linking, using the still video location information, the main data with the still video data;

decoding, by a decoder, the describing data according to the format information; and

providing, by a display, the describing data and the still video data in a synchronous manner with the main data,

wherein a time line of the describing data and the still video data is mapped to a time line of the main data based on time information,

wherein the time information is provided or not according to the indication information, and

wherein the time information is provided in a case that the indication information is a specific value, and the time information is not provided in a case that the indication information is not the specific value.

2. The method of claim 1, wherein the additional data is divided into a plurality of segment units.

3. The method of claim 2, wherein each segment unit is mapped to a specific time point on the time line of the main data considering the time information.

4. The method of claim 3, wherein the time information is one of a start time or a duration time of the corresponding segment unit.

5. A device comprising:

a processor configured to retrieve describing data, linking information, indication information, still video location information, and format information, the describing data being associated with main data,

wherein the still video location information indicates a location of the still video data and corresponds to still video location index information;

associate, using the linking information, the main data with the describing data; and

link, using the still video location information, the main data with the still video data;

a decoder configured to decode the describing data according to the format information; and

a display configured to output the describing data and the still video data in a synchronous manner with the main data,

wherein a time line of the describing data and the still video data is mapped to a time line of the main data based on time information,

wherein the time information is provided or not according to the indication information, and

wherein the time information is provided in a case that the indication information is a specific value, and the time information is not provided in a case that the indication information is not the specific value.

6. The device of claim 5, further comprising a storage medium, wherein the storage medium stores the additional data and the indication information.

7. The device of claim 5, wherein the additional data is divided into a plurality of segment units.

8. The device of claim 7, wherein each segment unit is mapped to a specific time point on the time line of the main data considering the time information.

9. A computer program product, tangibly embodied in a non- transitory machine-readable medium, the computer program product comprising instructions that, when read by a machine, operate to cause a controller to:

retrieve, by one or more processors, describing data, linking information, indication information, still video location information, and format information,

associate, using the linking information, a main data with the describing data

link, using the still video location information, the main data with the still video data,

wherein the still video location information indicates a location of the still video data and corresponds to still video location index information;

decode, by a decoder, the describing data according to the format information, and provide, by a display, the describing data and the still video data in a synchronous manner with the main data,

wherein a time line of the describing data is mapped to a time line of the main data based on time information,

wherein the time information is provided or not according to the indication information, and

wherein the time information is provided in a case that the indication information is a specific value, and the time information is not provided in a case that the indication information is not the specific value.

10. The computer program product of claim 9, wherein the describing data is divided into a plurality of segment units.

11. The computer program product of claim 10, wherein each segment unit is mapped to a specific time point on the time line of the main data considering the time information.
