Information storage medium containing interactive graphic stream, and reproducing apparatus and method thereof

Abstract

An information storage medium having an interactive graphics stream recorded thereon, and a reproducing apparatus and method thereof. The method includes loading and executing a program that selects one of the interactive graphics streams, and reading and reproducing the interactive graphics stream selected by the program With the medium, apparatus and method, text information written in a variety of languages and data shared by those languages are multiplexed and stored in one menu stream such that data is not redundantly stored and less storage space is wasted.

       25 . A method of selecting and reproducing one interactive graphics stream among at least one interactive graphics stream, comprising: 
 loading and executing a program that selects one of the interactive graphics streams; and    reading and reproducing the interactive graphics stream selected by the program.    
   
   
       26 . The method of  claim 25 , wherein the loading and executing comprises determining whether the interactive graphics stream obtained by executing the program comprises attribute information.  
   
   
       27 . The method of  claim 25 , wherein the program is a command included in a program object comprised of navigation commands.  
   
   
       28 . The method of  claim 25 , when an interactive graphics stream change program included in the reproduced interactive graphics stream is executed, further comprising reading and reproducing another interactive graphics stream selected according to new attribute information obtained by executing the interactive graphics stream change program.  
   
   
       29 . The method of  claim 28 , wherein the reading and reproducing of the interactive graphics stream selected according to the new attribute information comprises: 
 determining whether the other interactive graphics stream having the new attribute information is present; and    if determined that the interactive graphics stream having the new attribute information is present, reading and reproducing the interactive graphics stream having the new attribute information.    
   
   
       30 . The method of  claim 28 , wherein the interactive graphics stream change program is a button command included in a button object.  
   
   
       31 . The method of  claim 26 , wherein the attribute information comprises menu language information, viewer class information, sub-title language information, and audio language information.  
   
   
       32 . The method of  claim 25 , wherein the interactive graphics stream has text information for each language and shares information irrelevant to language with other interactive graphics streams.  
   
   
       33 . An information storage medium, comprising: 
 audiovisual (AV) data;    navigation data that is a set of navigation commands related to reproduction of the AV data; and    at least one interactive graphics stream,    wherein one among the at least one interactive graphics stream is selected according to a result of executing a program that selects the one among the at least one interactive graphics stream and is reproduced.    
   
   
       34 . The information storage medium of  claim 33 , wherein the program selects the one among the at least one interactive graphics stream according to attribute information of the interactive graphics stream, and the attribute information comprises menu language information, viewer class information, sub-title language information, and audio language information.  
   
   
       35 . An apparatus selecting and reproducing one among at least one interactive graphics stream, the apparatus comprising: 
 a processor which loads and executes a program that selects one among the at least one interactive graphics stream; and    a decoder which reads and reproduces the interactive graphics stream selected by the program.    
   
   
       36 . The apparatus of  claim 35 , wherein the processor obtains attribute information by loading and executing the program that selects the one among the at least one interactive graphics stream and determines whether one of the at least one interactive graphics stream comprising the attribute information is present.  
   
   
       37 . The apparatus of  claim 35 , wherein the program is a command included in a program object comprised of navigation commands.  
   
   
       38 . The apparatus of  claim 35 , wherein the processor loads and executes an interactive graphics stream change program included in the interactive graphics stream that is being reproduced and reads and reproduces another interactive graphics stream selected according to new attribute information obtained by executing the interactive graphics stream change program.  
   
   
       39 . The apparatus of  claim 38 , wherein the interactive graphics stream change program is a button command included in a button object.  
   
   
       40 . The apparatus of  claim 36 , wherein the attribute information includes menu language information, viewer class information, sub-title language information, and audio language information.
