Method for ensuring synchronous presentation of additional data with audio data
First Claim
1. A method of reproducing main data and additional data, the method being performed by a reproducing device and comprising:
- retrieving the main data, the additional data, and linking information, the linking information including at least one of first pointing information identifying the main data and second pointing information identifying the additional data;
associating the main data with the additional data using the linking information;
obtaining indication information indicating presence of time information as a single indicator, the time information being associated with mapping time of the additional data; 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.

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.

5. An apparatus for decoding a main data and an additional data, the apparatus comprising:
-
a retrieving unit that retrieves the main data, the additional data, and linking information, the linking information including at least one of first pointing information identifying the main data and second pointing information identifying the additional data; a reproducing unit that reproduces the main data and the additional data; and a controller that; associates the main data with the additional data using the linking information, obtains indication information indicating presence of time information as a single indicator, the time information being associated with mapping time of the additional data, 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. - View Dependent Claims (6, 7, 8)
