Abstract:

The traditional cable can not meet the high-definition video image transmission rate and transmission distance requirements. Therefor, a high-definition video optical fiber transmission with FPGA (Field Programmable Gate Array) as its core, on the basis of video image transmission technology is proposed. Using HDMI(High Definition Multimedia Interface) as the high-definition digital video image data input interface, the high-definition digital video image acquisition, preproces
sing and data stream cache control is realized, using the high-speed parallel FPGA features. According to the experiment, when the transmission rate is 2.5 Gbit/s, the transmission distance can reach 300 m. The program implements high-definition digital video fiber optic distant transmission without distortion.
