Object-based 3-dimensional audio service system using preset audio scenes

Abstract

Provided are an object-based three dimensional (3-D) audio service system using preset audio scenes and a method thereof. The system and the method are suggested for enabling a user to easily and conveniently watch and listen an object based 3-D audio service by eliminating inconvenience that requires a user to control each of object audio signals of sound sources. The system includes: audio input means for inputting an audio signal; preset audio scene generating means for extracting object audio signals from the audio signal inputted through the audio input means and generating more than one of 3-D audio scene information by arranging the extracted object audio signals in a 3-D space and editing features of each object; and encoding means for encoding and multiplexing the audio signal and the 3-D audio scene information for each object audio signal.

1 . An object-based audio reproducing apparatus comprising:
 de-multiplexing and decoding object-based audio contents and a plurality of preset audio scenes;   controlling the object-based audio contents using preset audio scene selected from a plurality of preset audio scenes by user, and   reproducing means the controlled object-based audio contents,   wherein each of the plurality of preset audio scenes is configured based on two or more different audio input signals;   
     
     
         2 . The object-based audio reproducing method of  claim 1 , wherein the preset audio scene is related to volume of each of object-based audio signals of the two or more different audio input signals included in the object-based audio contents. 
     
     
         3 . The object-based audio reproducing method of  claim 1 , wherein the preset audio scene is related to at least one among a location, a volume, a direction, and a sound field environment of each of object-based audio signals.
