几种电视立体声/双伴音制式解码的研究与实现

Study on and implementation of decoding in some stereo／dual sound systems

对世界主要的几种电视立体声／双伴音制式进行了分析比较，并结合中国电视广播附加双声道数字声制式的特点，研制了功能较完善的适用于多种制式解调的电路，介绍了ITT公司的多制式声音处理芯片（MSP3410D）的特点和组成，给出系统软件控制框图。

A few of main stereo／dual sound system in the world are compared and analyzed in this paper． A circuit of the more functions and demodulating multi-standard sound system is designed with the characteristics of Chinese TV broadcast additional dual sound digital audio system． The feature and the architecture of Multi-standard sound processor IC （MSP3410D) are introduced．The block diagram of system software control is given．
