Embodiment Construction

[0027] In order that the invention may be fully understood, a preferred embodiment thereof will now be described with reference to the accompanying drawings.

[0028] Embodiments of a method linking additional information with moving picture data in accordance with the present invention are described first.

[0029] FIG. 1 schematically shows a recording medium such as a DVD including script files containing additional information about moving picture data. The DVD of FIG. 1 is composed of three recording partitions, the first `Data Zone (DZ)` for storing digital data stream such as moving picture data, the second `Navigation Data Zone (NDZ)` for storing navigation data used to control reproduction of the stored digital data stream in the DZ, and the third `Script File Zone (SFZ)` for storing script files having additional and / or detailed information about moving picture data.

[0030] In the SFZ, at least one link data file, which links script files with corresponding sections of moving pic...

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.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a recording medium on which moving picture data have been recorded together with script files including additional information related with the moving picture data.[0003] The present invention further relates to a method of linking script files with moving picture data and relates to method and apparatus of reproducing the moving picture data along with script files thereof.[0004] 2. Description of the Related Art[0005] An optical disk such as DVD (Digital Versatile Disk) being able to store digital data is widely used in these days. A DVD can store not only audio data but also moving picture data of long time. A DVD has two recording partitions, one for storing digital data stream such as moving picture data, and the other for storing navigation data which are used to control reproduction of the stored digital data stream.[0006] Thus, when a DVD having digital data stream thereon is placed into a conventional D...
