光纤通信以其损耗低、高带宽、抗电磁干扰、保密性好等优点越来越多地应用在视频通信中[1～ 5 ]. 针对

光纤综合业务传输平台, 本文提出了一种将三路视频信息复用为一路视频信息的数字复接器的硬件电路

设计. 提高了传输容量和传输效率, 达到抗干扰、抗噪声的能力, 从而改善了传输平台的环境适应性及工作

性能. 该复接器硬件电路的设计采用EDA 技术, 以FPGA 器件为载体, 使用VHDL 硬件描述语言进行电路-Optical fiber communication with its low loss, high bandwidth, anti-electromagnetic interference, security and good benefits are increasingly used in video communications in the [1 ~ 5]. For the fiber optic integrated services delivery platform, this paper presents a three-way will be video information re-used as the way digital video multiplexer hardware circuit design. to improve the transmission capacity and transmission efficiency, to achieve anti-jamming, anti-noise capability, thereby improving the transmission platform, environmental adaptability and work performance. The re- connector hardware circuit design using EDA technology to FPGA devices as the carrier, using the VHDL hardware descr iption language circuit
