ＩＴＵ－ＴＨ．３２３协议规定了基于包交换网络上的多媒体通信系统标准。其中的多点控制单元（ＭＣＵ）可以在多点会议中提供多终端的通信能力，多点处理器（ＭＰ）在多点控制器（ＭＣ）的控制下实现音频、视频、交换混合和媒体流的其它处理。该文针对多点会议的需求，研制出一种基于多ＤＳＰ的音频多点处理器，通过数片ＤＳＰ的协同工作，完成高复杂度的多通道Ｇ．７２３．１的编解码运算，以便实现支持多路远程低速终端接入的电视会议系统，是一个具有很高性价比的解决方案。
ITU-TH. The 323 protocol specifies multimedia communication system standards based on packet switched networks. The multi-point control unit (MCU) can provide multi-terminal communication capability in a multi-point conference. The multi-point processor (MP) realizes audio, video, exchange mixing and media streams under the control of a multipoint controller Other processing. According to the demand of multi-point conference, this paper develops a multi-DSP based audio multi-point processor, which achieves high complexity multi-channel G through the cooperation of several DSPs. 723.1 encoding and decoding operations, in order to achieve support for multi-channel remote low-speed terminal access to the video conferencing system, is a very cost-effective solution.
