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.

12. A method of providing information for managing reproduction of video data on a digital storage medium, comprising:
-
providing a metadata indicator for indicating whether or not metadata set exists in a stream for the digital storage medium, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data, wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the stream for the digital storage medium and a second metadata indicator value indicating that the metadata set associated with the video data exists in the stream for the digital storage medium, and wherein a single metadata set is capable of being associated with plural video data or plural metadata sets are capable of being associated with a single video data. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A storage medium storing a data structure for managing reproduction of video data from the storage medium, comprising:
-
a data area storing video data; a navigation area storing a metadata indicator for indicating whether or not metadata set exists in a stream for the digital storage medium, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data, wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the stream for the digital storage medium and a second metadata indicator value indicating that the metadata set associated with the video data exists in the stream for the digital storage medium, and wherein a single metadata set is capable of being associated with plural video data or plural metadata sets are capable of being associated with a single video data. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
