Abstract: In demand of 4K or higher resolution video transporting in cockpit in the future, a common system related to ARINC818 video codec is referred and verified through DP video port in this article. The system receives DP video from the computer source,decoded in FPGA, and then packaged the video data according to ARINC818 protocol. The produced ARINC818 video is sent back to the system, decoded in FPGA, and transferred to DP video to display. 10 Gb/s data rate in ARINC818-3 standard is applied in this system, single lane 4K@30 Hz ARINC818 video receiving and dispatching is implemented ,as well as dual lane 4K@60 Hz, characterized with easy to use, feature-rich and flexible configuration.
Key words : ARINC818;4K resolution,;FPGA,;DP video
引言
航空電子技術(shù)的飛速發(fā)展對機載座艙視頻傳輸系統(tǒng)提出了更高的要求,傳統(tǒng)的DVI,、VGA等視頻接口難以滿足高分辨率視頻傳輸需求,尤其在視頻分辨率達到4K(3 840×2 160)或以上時,,由于鏈路速率大幅提升,在機艙內(nèi)復(fù)雜電磁環(huán)境下視頻傳輸鏈路極易受到干擾,導(dǎo)致傳輸可靠性變差,。ARINC818(航空電子數(shù)字視頻總線,,Avionics Digital Video Bus, ADVB)視頻總線采用光纖通道進行傳輸,其技術(shù)特點恰好滿足現(xiàn)代航電視頻數(shù)據(jù)總線的要求,,具備高帶寬,、高可靠性、低延遲,、非壓縮視頻傳輸、抵抗電磁干擾,、減輕線纜重量,、靈活性高、兼容性擴展性強等優(yōu)勢[1-2],。ARINC818總線已在波音787,、空客A350、A400M,、C-130J等飛機駕駛艙視頻傳輸系統(tǒng)中得到應(yīng)用[3],。
