The applications based on traditional digital cameras have been limited by distance  cost and networking. Gigabit Ethernet is a data transmission standard based on the IEEE 802.3 protocol  brings several benefits to image transmission. In this paper  we compare the main features of Gigabit Ethernet and traditional digital camera interfaces. And  we design a high speed image acquisition system which overcomes these application limitations by allowing cameras to send imaging data over Gigabit Ethernet. In this system  we design a highly efficient  bidirectional conversion device based on FPGA  converts imaging data from a camera to IP packets based on UDP protocol  and sends it to PCs over inexpensive Cat-5 copper LAN cable. At the PC  the Cat-5 cable plugs into a standard Gigabit Ethernet NIC(network interface card)  eliminating the need for a frame grabber. An communications application software is used to acquire the network data  construct and display the image. A simple and efficient acknowledge and resend mechanism was used to guarantee packet delivery. The system architecture and the communication protocol are discussed in details  the experiment and results are presented in this paper. 2010 IEEE.
