摘　　要：针对HD-SDI高清即高分辨率高传输速率的要求,提出了一种基于FPGA的高清视频采集系统,并给出了详细的系统实现方案。利用Xilinx FPGA的Rocket I/O GTP对均衡后的HD-SDI高清视频信号进行采集,解码后在2片DDR2中进行乒乓缓存,利用CYCPRESS的EZ-USB FX3实现USB3.0的数据控制及采集。结果表明,该方案设计能够满足高清HD-SDI视频采集要求且具有成本低、适用性广等优点。In view of the high⁃definition that is high resolution and high speed of data transmission of HD⁃SDI interface,the paper presents the design of HD⁃SDI video acquisition based on FPGA,and gives the implementation of the system in detail.The scheme has taken advantage of GTP of Xilinx FPGA to acquire high⁃definition HD⁃SDI video signal after equalizing.It completes the ping⁃pang cache in two pieces of DDR2 after decoding.The control and acquisition on USB3.0 by EZ⁃USB FX3 of CYPRESS is came true.The result show that the system can meet the request of the high definition of the digital image capturing of HD⁃SDI,and the scheme has the advantages of low cost and wide applicability.
