Abstract

In one embodiment, a first play list is generated if a first additional data stream is provided, and a second play list is generated if a second additional data stream is provided. The first play list links the main video data stream with the first additional data stream such that the main video data stream is reproduced with the first additional data stream if the first play list is reproduced. The second play list links the main video data stream with the second additional data stream such that the main video data stream is reproduced with the second additional data stream if the second play list is reproduced.

Claims

exact text as granted — not AI-modified
1 . A method of managing a main video data stream and multiple additional data streams, comprising: 
 generating a first play list if a first additional data stream is provided, the first play list linking the main video data stream with the first additional data stream such that the main video data stream is reproduced with the first additional data stream if the first play list is reproduced; and    generating a second play list if a second additional data stream is provided, the second play list linking the main video data stream with the second additional data stream such that the main video data stream is reproduced with the second additional data stream if the second play list is reproduced.    
   
   
       2 . The method of  claim 1 , wherein the first additional data stream includes a first audio data stream, and the second additional data stream includes a second audio data stream.  
   
   
       3 . The method of  claim 1 , further comprising: 
 recording the first play list and the second play list.    
   
   
       4 . The method of  claim 1 , wherein the first play list includes main path management information for a main path and sub-path management information for a sub-path, the main path management information for managing reproduction of the main video data stream, and the sub-path management information for managing reproduction of the first additional data stream.  
   
   
       5 . The method of  claim 1 , wherein the second play list includes main path management information for a main path and sub-path management information for a sub-path, the main path management information for managing reproduction of the main video data stream, and the sub-path management information for managing reproduction of the second additional data stream.  
   
   
       6 . The method of  claim 1 , wherein 
 the first play list includes first main path management information for a main path and first sub-path management information for a sub-path, the first main path management information for managing reproduction of the main video data stream, and the first sub-path management information for managing reproduction of the first additional data stream; and    the second play list includes second main path management information for a main path and second sub-path management information for a sub-path, the second main path management information for managing reproduction of the main video data stream, and the second sub-path management information for managing reproduction of the second additional data stream.    
   
   
       7 . The method of  claim 6 , wherein the first main path management information is the same as the second main path management information.  
   
   
       8 . The method of  claim 6 , wherein the first additional data stream includes a first audio data stream, and the second additional data stream includes a second audio data stream.  
   
   
       9 . A method of managing a main video data stream and multiple additional data streams, comprising: 
 providing a first play list if a first additional data stream is provided, the first play list linking the main video data stream with the first additional data stream such that the main video data stream is reproduced with the first additional data stream if the first play list is reproduced; and    providing a second play list if a second additional data stream is provided, the second play list linking the main video data stream with the second additional data stream such that the main video stream is reproduced with the second additional data stream if the second play list is reproduced.    
   
   
       10 . A method of reproducing, comprising: 
 reproducing at least one of a first play list and a second play list, the first play list linking a main video data stream with a first additional data stream such that the main video data stream is reproduced with the first additional data stream if the first play list is reproduced, and the second play list linking the main video data stream with a second additional data stream such that the main video stream is reproduced with the second additional data stream if the second play list is reproduced.    
   
   
       11 . The method of  claim 10 , wherein the reproducing step selectively reproduces one of the first play list and the second play list.  
   
   
       12 . The method of  claim 11 , wherein the reproducing step selectively reproduces one of the first play list and the second play list based on user input.  
   
   
       13 . The method of  claim 10 , wherein the first additional data stream includes a first audio data stream, and the second additional data stream includes a second audio data stream.  
   
   
       14 . The method of  claim 10 , wherein the first play list includes main path management information for a main path and sub-path management information for a sub-path, the main path management information for managing reproduction of the main video data stream, and the sub-path management information for managing reproduction of the first additional data stream.  
   
   
       15 . The method of  claim 10 , wherein the second play list includes main path management information for a main path and sub-path management information for a sub-path, the main path management information for managing reproduction of the main video data stream, and the sub-path management information for managing reproduction of the second additional data stream.  
   
   
       16 . The method of  claim 10 , wherein 
 the first play list includes first main path management information for a main path and first sub-path management information for a sub-path, the first main path management information for managing reproduction of the main video data stream, and the first sub-path management information for managing reproduction of the first additional data stream; and    the second play list includes second main path management information for a main path and second sub-path management information for a sub-path, the second main path management information for managing reproduction of the main video data stream, and the second sub-path management information for managing reproduction of the second additional data stream.    
   
   
       17 . The method of  claim 16 , wherein the first main path management information is the same as the second main path management information.  
   
   
       18 . The method of  claim 16 , wherein the first additional data stream includes a first audio data stream, and the second additional data stream includes a second audio data stream.  
   
   
       19 . A method of reproducing, comprising: 
 selectively reproducing one of a first additional data stream associated with a main video data stream and a second additional data stream associated with the main video data stream, the first additional data stream being linked with the main video data stream in a first play list, and the second additional data stream being linked with the main video data stream in a second play list.    
   
   
       20 . The method of  claim 19 , wherein the selectively reproducing step selectively reproduces one of the first additional data stream and the second additional data stream based on user input.  
   
   
       21 . The method of  claim 19 , wherein the first additional data stream includes a first audio data stream, and the second additional data stream includes a second audio data stream.  
   
   
       22 .
