用于生成多对象音频信号的侧信息比特流的方法和装置

Method and apparatus for generating side information bitstream of multi-object audio signal
Abstract:
Provided is a method and apparatus for generating a side information bitstream of a multi-object audio signal. The apparatus for generating a side information bitstream of a multi-object audio signal includes a spatial cue information input unit configured to receive spatial cue information generated in an encoder of the multi-object audio signal, a preset information input unit configured to receive preset information for the multi-object audio signal, and a side information bitstream generator configured to generate the side information bitstream based on the spatial cue information and the preset information. The side information bitstream includes a header region and a frame region, and the preset information is included in the frame region.
Abstract(Chinese):

提供了一种用于生成多对象音频信号的侧信息比特流的方法和装置。 用于生成多对象音频信号的侧信息比特流的装置包括：空间提示信息输入单元，被配置为接收在多对象音频信号的编码器中生成的空间提示信息;预设信息输入单元，被配置为接收预设信息 以及侧信息比特流发生器，被配置为基于空间提示信息和预设信息生成侧信息比特流。 侧信息比特流包括报头区域和帧区域，并且预设信息被包括在帧区域中。
