Method for ensuring synchronous presentation of additional data with audio data
First Claim
1. A method of retrieving main data and describing data, the method being performed by at least one device and comprising:
- retrieving, by a controller, a main data, a describing data, linking information, location information and still video location information, the main data including at least one audio data, the describing data corresponding to the main data based on the linking information,wherein the location information indicates where the describing data is found, andwherein the still video location information indicates a location of still video data and corresponds to still video location index information;
associating, by the controller, the main data with the describing data using the linking information;
retrieving, by the controller, indication information, the indication information indicating whether time information is provided or not;
providing, by the controller, time information in case that the indication information is a specific value,wherein a time line of the describing data is mapped to a time line of the main data based on the time information; and
outputting, by a display, the describing data and the still video data in a synchronous manner with the main 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.

5. An apparatus for retrieving main data and describing data, the apparatus comprising:
-
a controller that retrieves a main data, a describing data, linking information, location information and still video location information, the main data including at least one audio data, the describing data corresponding to the main data based on the linking information, wherein the location information indicates where the describing data is found, and wherein the still video location information indicates a location of still video data and corresponds to still video location index information, associates the main data with the describing data using the linking information, retrieves indication information, the indication information indicating whether time information is provided or not, and provides time information in case that the indication information is a specific value, wherein a time line of the describing data is mapped to a time line of the main data based on the time information; and a display that outputs the describing data and the still video data in a synchronous manner with the main data. - View Dependent Claims (6, 7, 8)
