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 at least one device and comprising:
- retrieving a main data stream, an additional data stream and management information, the main data stream including the main data, the additional data stream including the additional data associated with the main data, and the management information corresponding to the main data and including indication information and attribute information;
associating the main data with the additional data using the management information; and
reproducing the additional data according to the attribute information, wherein the additional data is reproduced in a synchronous manner with the main data, based on time information, the indication information indicating a presence of the time information and the time information being associated with presentation time of the additional data.

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.
