Research Of Long-distance Digital Video Transmission Technology Based On Fpga

The digital video is applied more and more widely, but is limited by the speed of transmission and the transmission distance is inversely proportional relationship, high-speed digital video transmission technology is the difficult problems in application. Optical fiber communication with large capacity, strong anti-interference ability, good secrecy performance, transmission distance and so the advantage is very suitable for the transmission of the video signal.In this paper, the FPGA technology as the core, using the optical fiber communication, camera link interface and a high speed serial-parallel conversion technology presents a high-speed digital video remote transmission scheme, and detailed analysis of the design process.Complete hardware circuit design in camera link interface circuit, serial/parallel conversion circuit, optical fiber communication circuit, the main control circuit and power supply circuit, main circuit; System control logic design of initialization of digital cameras, digital video collection, high speed data cache and decoding, data sending and receiving, high speed digital camera timing simulation program; On the problems encountered in the design of an in-depth analysis and research.
