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 a main data and an additional data, the method being performed by a reproducing device and comprising:

retrieving a main data stream including the main data and management information corresponding to the main data and including indication information and linking information, the linking information including location information of an additional data;

retrieving an additional data stream including the additional data based on the location information, the additional data stream being associated with the main data and being separate from the main data stream;

associating the main data with the additional data using the management information; and

reproducing, by the reproducing device, the additional data in a synchronous manner with the main data, based on the indication information and time information, the indication information indicating a presence of the time information, the time information being associated with mapping time of the additional data.

2. The method of claim 1, wherein the indication information further indicates a type of the time information.

3. The method of claim 1, wherein the management information includes attribute information of the additional data.

4. The method of claim 1, wherein the location information is address information of the additional data.

5. An apparatus for reproducing a main data and an additional data, the apparatus comprising:

a reproducing unit that reproduces the main data and the additional data; and

a controller that;

retrieves a main data stream including the main data and management information corresponding to the main data and including indication information and linking information, the linking information including location information of an additional data,

retrieves an additional data stream including the additional data based on the location information, the additional data stream being associated with the main data and being separate from the main data stream,

associates the main data with the additional data using the management information; and

controls the reproducing unit to reproduce the additional data in a synchronous manner with the main data, based on the indication information and time information, the indication information indicating a presence of the time information, the time information being associated with mapping time of the additional data.

6. The apparatus of claim 5,

wherein the indication information further indicates a type of the time information, and

wherein the controller decodes the additional data according to the type of the time information.

7. The apparatus of claim 5,

wherein the management information includes attribute information of the additional data, and

wherein the controller decodes the additional data according to the attribute information.

8. The apparatus of claim 5, wherein the location information is address information of the additional data.
