The objective of this research project is to develop a new type of hypermedia system with capability of advanced realtime linking to broadcasted video data.Major results of the project are as follows.(1) The Live Hypermedia System, which can acquire a desired set of video scenes from live television broadcasting programs using automated video scene recognition techniq, ues has been originally developed. In the system, information nodes and links are dynamically determined corresponding to the structure of the recognition model. The recognition models itself are expressed by the flexible compounds of state-transition rules and scene feature descriptions.This Live Hyper-media System is implemented on our original platiorm GOLS.In order to demonstrate the effectiveness, experimental evaluations of the Recall rate and Precision rate (video scence pick-up performance) for TV broadcasting programs have been done successfully.(2) To realize more flexible and user-oriented access and utilization of video data, more advanced methods of making high data models have been developed. Basic idea is to realize logical synchronization between related video, sound and document data.Higher-level recognition, retrieval and date authorization are successfully developed based on this idea. Experimented results reveal the effectiveness of there methods.

本研究项目的目标是开发一种新型超媒体系统，具有先进的实时链接广播视频数据的能力。该项目的主要成果如下：（1）直播超媒体系统，它可以获取一组所需的内容。最初开发了使用自动视频场景识别技术ues的来自现场电视广播节目的视频场景。系统中根据识别模型的结构动态确定信息节点和链接。识别模型本身由状态转换规则和场景特征描述的灵活组合来表达。该实时超媒体系统是在我们原始平台GOLS上实现的。为了证明有效性，对召回率和准确率进行了实验评估电视广播节目(视频场景拾取表演)已成功完成。(2)为了实现更灵活、更面向用户的视频数据访问和利用，开发了更先进的高数据模型制作方法。基本思想是实现相关视频、声音和文档数据之间的逻辑同步。基于此思想成功开发了更高级别的识别、检索和数据授权。实验结果揭示了这些方法的有效性。
