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.
