多对象音频信号的附加信息比特流产生方法和装置
摘要：
本发明涉及一种多对象音频信号的附加信息比特流产生方法和装置。本发明的多对象音频信号的附加信息比特流产生装置，其特征在于，包括接收从多对象音频信号的编码装置产生的空间提示信息的空间提示信息输入部、接收关于所述多对象音频信号的预设信息的预设信息输入部、以及利用空间提示信息和预设信息产生附加信息比特流的附加信息比特流产生部，其中，附加信息比特流包括头区域和帧区域，预设信息包括在帧区域。根据本发明，具有这样的效果，即，通过在对多对象音频信号编码时产生的附加信息比特流的帧区域中包括预设信息，从而在再现多对象音频信号期间，也可根据编辑者或声音工程师的意图来改变所设定的音响场景信息。
摘要（英）：

The present invention relates to a method and an apparatus for generating an additional information bit stream of a multi-object audio signal. The apparatus for generating an additional information bit stream of a multi-object audio signal according to the present invention includes a spatial cue information input unit for receiving spatial cue information generated from a multi-object audio signal encoding device, a preset information input unit for receiving preset information for a multi-object audio signal, and an additional information bit stream generating unit for generating an additional information bit stream by using the spatial cue information and the preset information. The additional information bit stream includes a header region and a frame region. The preset information is included in the frame region. The apparatus of the present invention is advantageous as it is capable of changing set audio scene information in accordance with the idea of an editor or a sound engineer even during reproduction of a multi-object audio signal because preset information is included in the frame region of the additional information bit stream generated during encoding of the multi-object audio signal.
