Design of USB Transmission System for Microprojection Video Signal
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
640480 resolution and 30 frame/s can be transmitted in real time with the system.
