Information storage medium containing multi-path data, and storage apparatus and player thereof

Abstract

A data recording and reproducing apparatus supporting multi-path recording reproduction, and an information storage medium on which multi-path data is recorded. The information storage medium includes at least one clip that is a recording unit containing presentation data for respective paths, wherein presentation data in a selected path is continuously reproduced without changing paths, and additional path information regarding a block of the path is recorded separately from the presentation data. Accordingly, it is possible to more effectively use a recording space and reduce the frequency of jumping to clips, thereby effectively reading the multi-path presentation data from the information storage medium.

1 . An information storage medium comprising a multi path block comprising a plurality of clips corresponding to a plurality of languages, the medium comprising:
 a first playlist corresponding to a first language, and a second playlist corresponding to a second language, the first playlist and the second playlist corresponding to a same title,   wherein the first playlist comprises a playitem pointing to a common clip which is regardless of language and a playitem pointing to a first clip corresponding to a first language among the plurality of clips of the multi path block, and the second playlist comprises a playitem pointing to the common clip which is regardless of language and a playitem pointing to a second clip corresponding to a second language among the plurality of clips of the multi path block.   
   
   
       2 . The information storage medium of  claim 3 , wherein each playitem points to a reproduction interval in the corresponding clip. 
   
   
       3 . An apparatus for reproducing data from an information storage medium comprising a multi path block comprising a plurality of reproduction paths corresponding to a plurality of languages, the apparatus comprising:
 a reading unit which reads data and playlists from the information storage medium; and   a reproducing unit which reproduces one of a plurality of clips, in the multi path block, based on playlists,   wherein the playlists comprises a first playlist corresponding to a first language, and a second playlist corresponding to a second language, the first playlist and the second playlist corresponding to a same title, and   the first playlist comprises a playitem pointing to a common clip which is regardless of language and a playitem pointing to a first clip corresponding to a first language among the plurality of clips of the multi path block, and the second playlist comprises a playitem pointing to the common clip which is regardless of language and a playitem pointing to a second clip corresponding to a second language among the plurality of clips of the multi path block.   
   
   
       4 . The apparatus of  claim 3 , wherein each playitem points to a reproduction interval in the corresponding clip.
