摘要
介绍了一种基于光纤传输的四路数字音视频监控系统方案.该系统采用时分复用技术,利用大规模专用集成电路、可编程逻辑器件CPLD以及光收发一体化模块,使设计的光纤传输系统在一根光纤中实现四路音视频和反向控制数据的传输.
This paper presents a project of four audio/video monitoring system base on optical fiber transmission. Which has been designed to transmit four - channel video/ audio and reverse control data through a single fiber line by large - scale special IC,CPLD device and the optical trans- ceiver.
