虽然目前存在一些基于镜头的视频分析方法能够为用户操纵视频提供一些方便.但由于在一个长视频中其镜头数太多，单元太小，而且单个视频镜头往往也无法表达出潜在的视频语义，所有这些都说明有必要在一个更高的层次上去组织视频.本文提出的视频目录层次结构把视频中镜头在其自身时间及内容的约束下形成若干镜群，再对镜群中的镜头进行聚类获得若干视觉相似镜头的集束--镜组，据此设计和实现的Videowser可让用户通过视频的目录层次结构进行非线性的浏览及观看；用户除了进行非线性的浏览外，还可根据自己的需要直接进行基于视频内容和语义的综合查询.

Now some shot based video analysing methods can make users some conveniency when they operating videos. But there are so many shots in a long video,and the shots are always short. one short shot can＇ t express the video＇ s latency semanteme,we need to organize the video on high semantic level. In this paper we give out a Video Directory Structure(VDS),in this structure shots are organized to some shotsets by their time and content,then the shots in each shotset are organized to some shotgroups by their visual content. User can browser and view the video nonlinearly though the VDS,and they also can query their needed video sequences by the videos＇ content in the desiged prototype System-Videowser.
