摘要
为解决在航空机载环境下,需要同时压缩记录多路和多制式视频信号的问题,设计实现了一个以TMS320DM8168为核心的,能够对多路高清视频进行采集、处理和压缩的高清视频编码系统,采用H.264算法对高清视频进行实时压缩编码。整个系统充分利用ARM核和DSP核的强大处理能力,经过对H.264视频编码算法的优化,整个系统能够同时处理1路分辨率1 600×1 200、4路分辨率720×576的视频和1路音频,视频压缩帧率最大能够达到60帧/s,满足了实时处理的要求,整个系统设计简单,扩展性好,处理能力强。
In order to solve the problem of recording multi-channel and multi standard video signals in airborne environment,a high definition video encoding system based on TMS320DM8168 is designed and implemented. With the system,multi-channel high definition video can be captured and compressed. The H. 264 algorithm is chosen for the real-time high definition video compression. With the excellent performance of ARM and DSP as well as the optimization in H. 264 algorithms and data structures,the system has the ability to handle one channel high definition video,four channel standard definition video and one channel audio at the same time,compression rate can be reached at 60 frame per second maximum. The system not only has met the requirements of real-time processing,but also has the advantages of simple design,good expansibility and strong processing ability.
