摘　　要：为满足超大高清显示屏的播放需求,实现超大高清视频播放的稳定性和实时性,设计了基于FPGA(Field Programmable Gate Array)的主从式光纤视频播放系统。该系统采用主从式的结构方式将多个控制器通过光纤连接,使主控制器与从控制器,从控制器与从控制器之间形成级联,利用多个控制器共同作用实现视频播放控制。其中DVI作为高清视频源输入接口,Artix-7系列FPGA控制电路,采用Aurora8b/10b协议通过光纤对视频进行实时传输,使用VerilogHDL语言对FPGA进行编程设计。通过实验测试和现场调试,该系统可稳定无失真的实现对高清视频的播放控制。In order to meet the playing requirements of large HD(High Definition)display and keep the stability and real-time performance of large high-definition video playback,a master-slave optical video playback system based on FPGA(Field Programmable Gate Array) was designed to form a cascade between the master controller and slave controller,slave controller and slave controller,using multiple controllers to achieve video playback. Among them,DVI(Digital Visual Interface)is used as the input interface of high-definition video source,and Artix-7 series FPGA control circuit to realize the video real-time transmission based on optical fiber through Aurora 8 b/10 b protocol. In addition selects the Verilog HDL to achieve FPGA programming design. And finally through experimental tests and site debugging,the system can control playback of high-definition video stably and correctly.
