ENCODING DEVICE FOR SUPPORTING A SCALABLE MULTI-CHANNEL AUDIO SIGNAL TO PROVIDE ADAPTIVE SOUND QUALITY ACCORDING TO THE TASTE OF A LISTENER, A DECODING DEVICE, AND A METHOD THEREOF

摘要

PURPOSE: An encoding device for supporting a scalable multi-channel audio signal, a decoding device, and a method thereof are provided to restore and compress a multi-channel audio signal for providing three-dimensional audio in a realistic broadcasting environment.;CONSTITUTION: A signal generator(201) generates a compatible multi-channel audio signal using a multi-channel audio signal and an audio object signal. An encoding unit(202) generates a first bit stream through a hierarchical encoding of the compatible multi-channel audio signal. A second encoding unit(203) generates a second bit stream through the encoding of the audio object signal. A bit stream formatter(204) generates an output bit stream using the first and second bit streams.;COPYRIGHT KIPO 2013;[Reference numerals] (101) Encoding device; (201) Signal generator; (202) First encoding unit; (203) Second encoding unit; (204) Bit stream formatter; (AA) Multichannel audio signal; (BB) Audio object signal; (CC) Compatible multichannel audio signal; (DD) Second bit stream; (EE) First bit stream; (FF) First additional information; (GG) Second additional information; (HH) Third additional information; (II) Output bit stream
