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1 Gbit/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16 Hz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607.8 Mbit/s，且成本低、体积小、功耗低、性能稳定，满足了工程需要。

Abstract

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 3921 0408 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.
