Abstract
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.关键词
