MULTI-OBJECT AUDIO SIGNAL ENCODING AND DECODING APPARATUS INCLUDING ADDITIONAL INFORMATION BIT STREAM CONVERSION AND METHOD THEREOF CAPABLE OF CONVERTING A MULTI-OBJECT AUDIO BIT STREAM AND A SPATIAL AUDIO CODING BIT STREAM

摘要

PURPOSE: A multi-object audio signal encoding and decoding apparatus including additional information bit stream conversion and method thereof are provided to consume various audio objects by combining audio content through various methods.;CONSTITUTION: A rendering information creation unit creates first rendering information for a multi-object audio signal. A rendering unit(303) creates spatial queue information for the multi-object audio signal based on second rendering information for the first rendering information and the multi-object audio signal. The second rendering information is transmitted from an encoding apparatus. The second rendering information includes preset ASI(Audio Scene Information) for the multi-object audio signal.;COPYRIGHT KIPO 2013;[Reference numerals] (301) Parsing unit; (303) Rendering unit; (311) Second matrix unit; (313) First matrix unit; (AA) Representative SAOC bit stream; (BB) Representative SAC bit stream; (CC) Object control information playback system information
