摘　　要：随着智能手机和监控安防设备的普及，视频随手拍和监控视频摄像头已经布满了生活中的各个角落。如手机、行车记录仪、安防摄像头、执法记录仪等设备每天都大批量地制作出视频数据。这些视频数据可能记录着重要的信息，视频取证已经成为取证系统中非常重要的一环。遗憾的是这些宝贵的视频数据有时会遭遇各种意外，有的是设备故障导致视频录制中断，录制出来的视频无法播放，有的则是被人为删除，虽然有数据恢复软件可以恢复视频数据，但是由于某些视频封装格式对文件的完整性要求较高，恢复出来的数据有时并不是完整的数据，其中有一小部分数据可能已经被覆盖，这会导致视频损坏无法播放，但是没有被覆盖的数据可能就有关键信息，这时需要有一项技术可以对这些不完整的视频进行修复，使得视频可以重新播放。With the popularity of Smart-phone and Surveillance camera. It is easy to make a video. The equipment likes Smart-phone,Tachograph,Surveillance camera, Site enforcement Recorder, etc. make a large number of videos every day. This videos may take some important message. Video evidence has been a very important part of evidence system. It is pity that these valuable video data are easily destroyed, such as equipment failure and malicious delete file. Although there have recovery software can help us find lost files. But some video format is highly sensitive with the integrity of file. The files that were recovered by software may lost some parts or may be covered by other files. These files can ＂t be opened by the player. In order to solve these problems, we need a technology that can repair the videos that have been damaged.
