Abstract :
A professional DVI-Video optical fiber transceiver was designed based on FPGA (Field Programmable Gate Array) in order to meet the need of real-time LED display. The system could be used to transmit a non-loss, real-time video source whose resolution was 1024 × 768 and refresh rate was 60Hz in a single mode optical fiber. The top-down design method was used while programming FPGA. Some module design ideas were discussed including video data acquisition, caching, framing, frame detecting and video reproducing. The required bandwidth of each module was analyzed and calculated in details. Some relevant simulation results were also given. In practical test, real-time video display was achieved. And the transmission rate of coded data was up to 2Gbps, and the transmission distance could reach 10km.
