APPARATUS AND METHOD FOR CODING AND DECODING MULTI-OBJECT AUDIO SIGNAL WITH VARIOUS CHANNEL INCLUDING INFORMATION BITSTREAM CONVERSION

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.
