    Abstract: Disclosed is a system for authoring metadata that describe multimedia contents. A storage device loads information on a currently edited metadata document so as to describe multimedia contents, and a metadata editor visualizes the loaded metadata document according to a predetermined method, and allows a user to edit the metadata document. A multimedia access reproducer accesses the input multimedia contents to reproduce corresponding multimedia contents, and an inter-media metadata interface links the multimedia access reproducer and the metadata editor to browse contents and effectively edit information relating to a specific interval of multimedia contents. A metadata output device outputs information on the loaded metadata document according to a predefined format.

    Abstract: A multi-object audio encoding and decoding apparatus supporting a post downmix signal may be provided. The multi-object audio encoding apparatus may include: an object information extraction and downmix generation unit to generate object information and a dowmnix signal from input object signals; a parameter determination unit to determine a downmix information parameter using the extracted downmix signal and the post downmix signal; and a bitstream generation unit to combine the object information and the downmix information parameter, and to generate an object bitstream.

    Abstract translation: 可以提供支持后降混信号的多对象音频编码和解码装置。 多对象音频编码装置可以包括:对象信息提取和下混合生成单元,用于从输入对象信号生成对象信息和后同步信号; 参数确定单元,用于使用提取的下混合信号和后降混信号确定下混信息参数; 以及比特流生成单元,用于组合对象信息和下混信息参数,并生成对象比特流。
