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 x 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.
