摘　　要：针对高分辨率视频远程传输与切换需求,提出了远程差分视频解决方案,研究了基于差分信号的远程视频发送技术、基于均衡与延迟控制的高分辨率视频信号完整性技术,设计了基于AD8176芯片的加固型差分视频切换矩阵,差分视频实现三对双绞线发送,传输距离达到200m,视频切换采用矩阵式,容量为16*9,视频带宽350MHz,实现了1600*1200高分辨率视频的路由控制,在指挥自动化、会议电视、视频监控等领域应用前景广泛。In order to realize the transmission and switching of the high definition video, the remote differential video solution is proposed. This paper researches the remote video transmission technology based on the differential signal and the high definition video signal in- tegrity technology based on the equalization and delay control. The rugged video switching matrix based on the AD8176 is designed. The transmission distance is up to 300 meter along three differential twisted pair, the switching is matrix--type, the volume is 16 ＊ 9, the system bandwidth is up to 350MHz, the 1600 ＊ 1200 high definition video routing control is achieved. The solution can have a wide application in video monitoring.
