System and method for transmitting/receiving object-based audio

Abstract

Provided is a system and method for transmitting/receiving an object-based audio. The system includes: a pre-processing unit for receiving an audio signal from diverse sources of outside and creating an object-based audio signal through a pre-processing procedure; an object-based audio editing unit for editing the object-based audio signal from the pre-processing unit and organizing an audio scene; an object-based audio coding unit for coding/multiplexing information on the object-based audio signal and the audio scene from the object-based audio editing unit and creating object-based audio contents; and a transmitting unit for transmitting the object-based audio contents from the object-based audio coding unit.

 a coding unit for generating object-based audio contents comprising the object-based audio signals, and the plurality of audio scenes; and 
 a transmitting unit for transmitting the object-based audio contents, and background sound to an object-based audio reproducing system, 
 wherein the plurality of audio scenes are different from each other, and are selected by a second user of the object-based audio reproducing system, 
 wherein the object-based audio signals are reproduced based on at least one of space information, location information, and a reproducing environment of object-based audio signal included in the audio scene selected by the second user. 
 
 
     
     
       2. The system as recited in  claim 1 , wherein the coding unit generates the object-based audio contents comprising the plurality of audio scenes selected by the first user. 
     
     
       3. The system as recited in  claim 1 , wherein the editing unit determines the plurality of audio scenes intended by the first user, to synthesize the object-based audio signals using one of the plurality of audio scenes selected by the second user. 
     
     
       4. The system as recited in  claim 3 , wherein the editing unit determines a level of an object-based audio signal. 
     
     
       5. The system as recited in  claim 4 , wherein the level information comprises volume of an object-based audio signal. 
     
     
       6. The system as recited in  claim 1 , wherein the coding unit multiplexes the object-based audio signals and the plurality of audio scenes and generates the object-based audio contents. 
     
     
       7. The system as recited in  claim 1 , wherein the editing unit determines at least one of a location information of an object-based audio signal, and a space information of an object-based audio signal. 
     
     
       8. The system as recited in  claim 7 , wherein the location information comprises distance information and angle information from a virtual user location to the object-based audio signal,
 wherein the space information comprises characteristics information such as a size, a form and a reverberation time of the space, and reflection, absorption and penetration of an inside sound. 
 
     
     
       9. An object-based audio transmitting method implemented by an object-based audio transmitting system, comprising:
 creating a plurality of object-based audio signals; 
 editing the object-based audio signals by mixing the object-based audio signals and adding a sound effect into the object-based audio signals; 
 determining a plurality of audio scenes using the edited object-based audio signals by a first user; 
 generating object-based audio contents comprising the object-based audio signals and the plurality of audio scenes; 
 transmitting the object-based audio contents and a background audio signal to an object-based audio reproducing system, 
 wherein the plurality of audio scenes are different from each other, and are selected by a second user of the object-based audio reproducing system, 
 wherein the object-based audio signals are reproduced based on at least one of space information, location information, and a reproducing environment of object-based audio signal included in the audio scene selected by the second user. 
 
     
     
       10. The method as recited in  claim 9 , wherein the generating step comprises generating the object-based audio contents comprising the at least one of audio scenes. 
     
     
       11. The method as recited in  claim 9 , wherein the determining step determines audio scenes of the plurality of audio scenes intended by the first user, P 1  to synthesize the object-based audio signal using one of the plurality of audio scenes selected by the second user. 
     
     
       12. The method as recited in  claim 11 , wherein the determining determines a level of an object-based audio signal. 
     
     
       13. The method as recited in  claim 12 , wherein the level information comprises a volume. 
     
     
       14. The method as recited in  claim 9 , wherein the generating multiplexes the object-based audio signal and the audio scenes and generates the object-based audio contents. 
     
     
       15. The method as recited in  claim 9 , wherein the determining determines the audio scenes comprising at least one of a location information of an object-based audio signal and a space information of an object-based audio signal. 
     
     
       16. The method as recited in  claim 15 , wherein the location information comprises distance information and angle information from a virtual user location to the object-based audio signal,
 wherein the space information comprises characteristics information such as a size, a form and a reverberation time of the space, and reflection, absorption and penetration of an inside sound.
