Abstract: Because of USB2.0 Specification has been widely used in the field of high-speed transports, a video capture card is designed by using video capture chip TDA8709 and USB2.0 interface chip CY7C68013. It can display the real-time video image in the computer that captured from CCD camera in 20MB frequency and display 50 frames image per second when the resolution is 800×600.
