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.
摘要:
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.
