Recording medium containing moving picture data and additional information thereof and reproducing method and apparatus of the recording medium
First Claim
1. A method of retrieving information for managing video data, comprising:
- receiving, by a receiving unit, a data stream including video data;
storing, in a buffer memory, the video data;
retrieving, by a controlling unit, linking information for associating a metadata set with the video data;
retrieving, by the controlling unit, a metadata indicator for indicating whether the metadata set exists in a stream including the linking information, the metadata set being additional information describing the video data, and the linking information being used for identifying the metadata set associated with the video data,wherein the metadata indicator is a flag,wherein the metadata indicator indicates that the metadata set associated with the video data exists in the stream when the metadata indicator has a first metadata indicator value, andwherein the metadata indicator indicates that the metadata set associated with the video data does not exist in the stream when the metadata indicator has a second metadata indicator value;
decoding, by a decoding unit, the video data; and
outputting, by a display, the video data and the additional information.

Abstract
The present invention relates to a recording medium containing moving picture data and additional information thereof and to reproducing method and apparatus of the recording medium. The present recording medium has script files including additional information about moving picture data, e.g., scene descriptive text and introduction of characters, etc. In addition, information linking each script file with a section of moving picture data to be presented with contents of the script file is included in a link data file or is contained in a filename of the script file. In reproduction of the recording medium, a script file linked with presently reproduced moving picture data section is determined and searched for based on the link data file or every filename of the script files, and contents of the found script file are presented together with the presently reproduced moving picture data. Furthermore, previously presented additional information is removed depending on data or filename of the found script file.

7. A video medium player comprising:
-
a receiving unit configured to receive a data stream including video data; a buffer memory configured to store the video data; a controlling unit configured to; retrieve linking information for associating a metadata set with the video data; retrieve a metadata indicator for indicating whether the metadata set exists in a stream including the linking information, the metadata set being additional information describing the video data, and the linking information being used for identifying the metadata set associated with the video data, wherein the metadata indicator is a flag, wherein the metadata indicator indicates that the metadata set associated with the video data exists in the stream when the metadata indicator has a first metadata indicator value, and wherein the metadata indicator indicates that the metadata set associated with the video data does not exist in the stream when the metadata indicator has a second metadata indicator value; a decoding unit configured to decode the video data; and a display configured to output the video data and the additional information. - View Dependent Claims (8, 9, 10, 11, 12)
