    Abstract: 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 taking, as an input, spatial cue information generated from a multi-object audio signal encoding device, a preset information input unit for taking, as an input, 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.

    Abstract translation: 本发明涉及一种用于生成多目标音频信号的附加信息比特流的方法和设备。 根据本发明的用于产生多客体音频信号的附加信息比特流的设备包括：空间线索信息输入单元，用于将从多客体音频信号编码装置产生的空间线索信息作为输入; 预置信息输入单元，用于以多个对象音频信号的预置信息作为输入;以及附加信息位流生成单元，用于通过使用空间提示信息和预置信息生成附加信息位流。 附加信息比特流包括头部区域和帧区域。 预设信息包含在边框区域中。 本发明的设备是有利的，因为即使在多对象音频信号的再现期间，由于预置信息被包括在帧的区域中，所以它能够根据编辑者或音响工程师的想法来改变所设置的音频场景信息 在多目标音频信号的编码期间产生的附加信息比特流。

    Abstract: Provided are an object-based three dimensional (3-D) audio service system using preset audio scenes and a method thereof. The system and the method are suggested for enabling a user to easily and conveniently watch and listen an object based 3-D audio service by eliminating inconvenience that requires a user to control each of object audio signals of sound sources. The system includes: audio input means for inputting an audio signal; preset audio scene generating means for extracting object audio signals from the audio signal inputted through the audio input means and generating more than one of 3-D audio scene information by arranging the extracted object audio signals in a 3-D space and editing features of each object; and encoding means for encoding and multiplexing the audio signal and the 3-D audio scene information for each object audio signal.
