摘　　要：提出了一种无压缩多路数字视频光纤传输系统 ,该系统基于时分复用技术采用比特串行数字视频传输方式实现在一根光纤中传输多路视频信号 介绍了系统设计思想、关键技术及高速数据接口设计 ,并通过实验证明该系统工作稳定、实时传输效果好。A solution of uncompressed multichannel digital video transmission system is presented. Based on time-division multiplexing technology and the serial digital video transmission, the system can transfer multichannel video signal over a single optical fiber. Designing scheme, main technologies and high speed data interface design are introduced in detail. Experiments show that the system works stably and has a good effect of real-time transmission. It is a good and practical scheme for security and surveillance systems.
