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.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An object-based audio transmitting system, comprising: a processing unit for creating a plurality of object-based audio signals; an editing unit comprising an audio editing block configured to edit the object-based audio signals by mixing the object-based audio signals and adding a sound effect into the object-based audio signals, an audio scene organizing block configured to determine a plurality of audio scenes using the edited object-based audio signals by a first user, 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.
