无人机（UAV）投入作战使用的最大优势一直体现在情报侦察上，而视频图像信号是无人机的主要侦察信息，因此，视频记录仪是无人机系统一个重要的信息获取手段。当前，各种类型的无人机使用的视频记录仪主要是还是模拟视频记录仪，记录载体一般是磁带,这对视频的后期处理和分析带来了很大的不便.有效的解决方法就是实现视频信息的数字化，并利用数字压缩算法压缩视频信息的容量。VxWorks 是嵌入式实时操作系统，可靠性高，稳定性好。此文研究了VxWorks 平台的嵌入式视频记录仪的实现。

Abstract: the information reconnaissance has been the biggest advantage in the UAVs
application, and the video image signal is the major UAV reconnaissance information. Video
Recorder is an important means of access to information in UAV systems. At present, most of
video recorder in use is analog recorder with tape. This has brought a lot of inconvenience to video post-processing and analysis. The effective solution realizes the video information digitization, And use of digital video compression algorithm compresses information capacity. VxWorks is a strong RTOS, this thesis researched design and Implementation of video recorder on UAV based on VxWorks.
Keywords: embedded, video recorder, VxWorks, DSP
