Method for generating and consuming 3d audio scene with extended spatiality of sound source

Abstract

A method of generating and consuming 3D audio scene with extended spatiality of sound source describes the shape and size attributes of the sound source. The method includes the steps of: generating audio object; and generating 3D audio scene description information including attributes of the sound source of the audio object.

1 . A method for generating a three-dimensional audio scene with a sound source whose spatiality is extended, comprising the steps of: 
 a) generating a sound object; and    b) generating three-dimensional audio scene description information including sound source characteristics information for the sound object,    wherein the sound source characteristics information includes spatiality extension information of the sound source which is information on the size and shape of the sound source expressed in a three-dimensional space.    
     
     
         2 . The method as recited in  claim 1 , wherein the spatiality extension information of the sound source includes sound source dimension information that is expressed as an x component, y component and z component of a three-dimensional rectangular coordinates.  
     
     
         3 . The method as recited in  claim 2 , wherein the spatiality extension information of the sound source further includes geometrical center location information of the sound source dimension information.  
     
     
         4 . The method as recited in  claim 2 , wherein the spatiality extension information of the sound source further includes direction information of the sound source and describes a three-dimensional audio scene by extending the spatiality of the sound source in a direction vertical to the direction of the sound source.  
     
     
         5 . A method for consuming a three-dimensional audio scene with a sound source whose spatiality is extended, comprising the steps of: 
 a) receiving a sound object and three-dimensional audio scene description information including sound source characteristics information for the sound object; and    b) outputting the sound object based on the three-dimensional audio scene description information,    wherein the sound source characteristics information includes spatiality extension information which is information on the size and shape of the sound source expressed in a three-dimensional space.    
     
     
         6 . The method as recited in  claim 5 , wherein spatiality extension information of the sound source includes sound source dimension information that is expressed as an x component, y component and z component of a three-dimensional rectangular coordinates.  
     
     
         7 . The method as recited in  claim 6 , wherein the spatiality extension information of the sound source further includes geometrical center location information of the sound source dimension information.  
     
     
         8 . The method as recited in  claim 6 , wherein the spatiality extension information of the sound source further includes direction information of the sound source and describes a three-dimensional audio scene by extending the spatiality of the sound source in a direction vertical to the direction of the sound source.  
     
     
         9 . A three-dimensional audio scene data stream with a sound source whose spatiality is extended, comprising: 
 a sound object; and    three-dimensional audio scene description information including sound source characteristics information for the sound object data,    wherein the sound source characteristics information includes spatiality extension information which is information on the size and shape of the sound source expressed in a three-dimensional space.    
     
     
         10 . The data stream as recited in  claim 9 , wherein the spatiality extension information of the sound source includes sound source dimension information that is expressed as an x component, y component and z component of a three-dimensional rectangular coordinates.  
     
     
         11 . The data stream as recited in  claim 9 , wherein the spatiality extension information of the sound source further includes geometrical center location information of the sound source dimension information.  
     
     
         12 . The data stream as recited in  claim 9 , wherein the spatiality extension information of the sound source further includes direction information of the sound source and describes a three-dimensional audio scene by extending the spatiality of the sound source in a direction vertical to the direction of the sound source.
