摘　　要：针对高清视频信号的数据量大,所需的传输带宽高的问题,设计了嵌入式千兆网高清视频传输系统。该系统选用Altera公司Cyclone II系列的FPGA芯片为主控制器,完成数据的采集、处理和传输控制。系统采集端选用Camera Link接口,其数据传输速率最高可达1Gbit/s,可为高清相机提供简单、灵活的连接。数据传输方式上采用千兆以太网技术,使视频信号不经压缩即可高速远程传输。实验采用分辨率为1 392列×1 040行×8位,帧频为16Hz的紫外相机,结果表明,该系统每秒最高可传输52帧图像数据,数据流速度达到607.8Mbit/s,且成本低、体积小、功耗低、性能稳定,满足了工程需要。To the problem of large amount of high-definition video signal and the required transmission bandwidth,the embedded Gigabit Ethernet high-definition video transmission system is designed.The system selects Altera Cyclone Ⅱ family FPGA chip as main controller,completing control of data acquisition,transfer and data processing control.System acquisition end selects the Camera Link interface,which data transfer rate up to 1 Gbit/s,and can provide a simple,flexible connection for high-definition camera.The data transmission mode selects Gigabit Ethernet technology,so that the video data can be transferred without any compression in high speed.The experiment uses a resolution of 1 392×1 040×8 bit,a frame rate of 16 Hz ultraviolet camera.The results show that the system can be transmitted to a maximum 52-frame image data per second,and the data flow velocity reaches 607.8 Mbit/s.The system has the characteristics of low cost,small size,low power consumption,stable performance,meeting most lossless video transmission system requirements.
