摘　　要：设计并实现了一种基于USB2.0的微投影视频信号传输系统。系统利用上位机程序实时抓取播放器画面图像来获取视频数据,并通过USB接口进行数据传输,USB设备端数据的采集控制通过FPGA外部逻辑电路实现。系统在FLCOS微投影实验平台上进行了验证,结果表明系统传输速率达到18.75Mbyte/s,能够实现16位高彩色、640×480、30帧/s视频数据的实时传输。A USB2.0-based transmission system of micro-projection video signal is designed and implemented.In the system,frame images and the data of video on a media player are grabbed in real time,which are transmitted with USB interface and acquired with external FPGA logic circuit on the USB equipment.The design is verified on a FLCOS microprojection platform,and it shows that a transmission rate of 18.75 Mbyte/s is obtained,and video of 16-bit color,640×480 resolution and 30 frame/s can be transmitted in real time with the system.
