Abstract
In order to meet the special industry needs for high resolution video monitoring, a video acquisition and network transmission system based on FPGA (Field Programmable Gate Array) is presented. According to ⅡC (Intel-Integrated Circuit) protocol, FPGA is used to initialize the registers in image sensor. The image sensor outputs 16-bit YCbCr video signal to FPGA. The video signal's definition is 1 024 ×768 and its frame rate is 8 Hz. FPGA samples the video signal with the rate of 4 Hz. Utilizing a piece of DDR SDRAM as frame buffer, the video signal is inverted to Ethernet data frame format with the Ethernet controller module in FPGA. The Ethernet data frame is transmitted to physical layer chip by the physical interface module. So the video data captured by the image sensor will be transmitted by Ethernet. The design of the system is realized with VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and verified on Xilinx FPGA board. The results show that the system can effectively transfer the high resolution video image.关键词
