摘　　要：针对USB2. 0接口由于速率和带宽不够而无法满足高清视频实时传输的问题,提出了一种基于FPGA的USB3.0高清视频传输系统方案,并从吞吐速率角度分析了方案的可行性;采用SDRAM缓存视频数据和在视频流中插入帧同步码的方法,保证视频图像的完整和像素对齐;对系统进行了模拟测试和实际高清视频传输测试,测试结果表明:该系统实现了高清视频的实时传输,以320 MB/s的速度稳定传输视频数据。In order to solve the problem that the USB2.0 interface can not meet the real-time transmission requirement of HD( high-definition) video due to insufficient speed and bandwidth, a USB3.0 HD video transmission system based on FPGA is proposed, and the feasibility of the scheme is analyzed from the perspective of throughput rate. The SDRAM is used to buffer video data and the frame synchronization code is inserted into the video stream to ensure the integrity and pixel alignment of the video image. The system is simulated and tested with real HD video transmission. The test result shows that the system realizes the real-time transmission of HD video, and stably transmits the video data at a speed of 320 MB/s.
