This paper proposes a functional video handling technique based on structured video. The video handling architecture, which includes a video data structure, file management structure, and visual interface structure, is introduced as the core concept of this technique. One of the key features of this architecture is that the newly proposed video indexing method is performed automatically based on image processing. The video data structure, which plays an important role in the architecture, has two kinds of data structures: content and node. The central idea behind these structures is to separate the video contents from the processing operations and to create links between them. Video indexes work as a backend mechanism in structuring video content. A prototype video handling system called the MediaBENCH, a hypermedia basic environment for computer and human interactions, which demonstrates the actual implementation of the proposed concept and technique, is described. Basic functions such as browsing and editing, which are achieved based on the architecture, exhibit the advantages of structured video handling. The concept and the methods proposed in this paper assure various video-computer applications, which will play major roles in the multimedia field.
