摘要
多路视频编码传输系统已经越来越广泛地应用到民用无人机航拍记录系统、视频监控、智能交通系统,以及机载航空领域。系统除了对视频压缩的效率和质量有较高的要求,传输速度也近乎要求零延迟。设计了一套嵌入式视频编码传输系统,采用H. 264编码标准和FC网络协议,设计了基于FPGA的硬件平台和软件架构,实现了性能良好的四路H. 264实时视频编码FC传输系统。设计成果已用于机载实时视频编码传输应用环境,具有重要的实用意义。
Multi channel video transmission system has been widely applied to civilian UAV aerial recording system,video surveillance,and intelligent transportation system and so on.The video encode transmission system is an important part of AEW.In addition to the high efficiency and quality of video compression,the transmission speed is almost zero delay.This paper designs an embedded video encode transmission.It uses H.264 video coding standard and FC network protocol,designs a hardware platform and software architecture based on FPGA,and realizes a four channel H.264 real time video coding FC transmission system with good performance.The design results will be used for AEW real time video coding transmission application environment,have important practical significance.
