A STRUCTURED VIDEO HANDLING TECHNIQUE FOR MULTIMEDIA SYSTEMS

This paper proposes a functional video handling technique based on str uctured video. The video handling architecture, which includes a video data structure, file management structure, and visual interface struc tures, is introduced as the core concept of this technique. One of the key features of this architecture is that the newly proposed video in dexing method is performed automatically based on image processing. Th e video data structure, which plays an important role in the architect ure, has two kinds of data structures: content and node. The central i dea 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 envir onment for computer and human interactions, which demonstrates the act ual implementation of the proposed concept and technique, is described . Basic functions such as browsing and editing, which are achieved bas ed on the architecture, exhibit the advantages of structured video han dling. The concept and the methods proposed in this paper assure vario us video-computer applications, which will play major roles in the mul timedia field.
