变色龙加解扰管理系统,在国外国家级网络中得到广泛的应用,针对中国大陆市场进行二次研发。实现了在单向网络开展广播式综合扩展业务功能,形成了领先的技术优势。其可靠性、安全性高,硬件连锁开发,控制软件成熟、管理功能强大,帐单系统针对国情设计。 1 系统原理 华龄变色龙加解扰管理系统是以扰频方式进行加扰,即通过头端动态压缩射频信号的水平、垂直同步脉冲从而对图像信号进行加扰。在网络传输加扰图像的同时,将控制信号通过AM调变技术,使它叠加
Chameleon plus descrambling management system, in foreign countries-wide network has been widely used in secondary development for the Chinese mainland market. In the one-way network to achieve a comprehensive business expansion of radio capabilities, formed a leading technology advantage. Its reliability, high security, hardware chain development, control software is mature, powerful management, billing system designed for the national conditions. 1 System Principle Huarong chameleon plus descrambling management system is scrambled by scrambling, that is, through the first end of the dynamic compression RF signal level, vertical sync pulse to the image signal scramble. In the network transmission scramble image at the same time, the control signal through the AM modulation technology, it superimposed
