摘　　要：为了实现飞行器试验中视频图像传输解码的需求,提出了一种遥测视频解码解决方案,并完成了系统的软硬件设计。该解码系统同时采用了硬解压和软解压两种工作方式,硬解压采用"ASIC+处理器"的设计平台,运行Linux系统管理系统。软解压采用高性能的工控机为硬件平台,利用软件实现了视频数据H.264方式的解码、保存、同步播放等功能。实际应用表明,该系统能够实现遥测数据中视频信息的实时显示、存储和回放,达到了设计要求。In order to realize the demand of video image transmission and decoding in the aircraft tests, the author design a telemetry video decoding solution, and the hardware and software design of the system is completed. The system adopts both the hard decompression and the soft decoder ways to decode the video data. The design platform of ASIC＋Processor and the Linux operation system are used in the Hard decompression . High performance Industrial PC is adopted in the soft decoder as hardware platform, and various functions including the decoding, saving and synchronized playing have been realized. The practical application shows that the system can realize real-time display, storage and playback of the video information in the remote sensing data, and it can reach the design requirements.
