摘要
航空电子数字视频总线(ARINC818)是针对航空领域高清视频信号远距离传输提出的一种视频接口协议,它具有高带宽、低延迟、小衰减等特点。研究对ARINC818协议进行了解析,设计了一套光纤传输收发系统,采用FPGA进行视频的编解码,最高可实现6.25 Gbps速率下1920×1080@60 Hz的高清视频传输。经过高低温(-45℃~70℃)环境验证,光纤传输信号在100 m长度内无衰减,视频显示清晰、无串扰。
Avionics Digital Video Bus(ARINC818)is a new standard generated for the long-distance transmission of high definition video.It has the characteristics of high bandwidth,low delay and slow attenuation.In this system,the protocol of ARINC818 was analyzed and the sending and receiving optical fiber transmission was designed.Using FPGA,the system could easily achieve HD video transmission with 6.25 Gbps rate.Finally the stability and integrity of the transmission system was verified by function test and the high and low temperature test.The video was legible without crosstalk after 100 m distance transmission.
