摘要：

This paper, describes a proposal of an extended event model using a media synchronization method for video hypermedia applications. In this extended event model, video and metadata are synchronized by periodically inserting event information in the video multiplex. We considered the following design policies: 1) a model that is independent of the video format and delivery method, 2) the synchronization accuracy can be tuned depending on the purpose and use of the metadata. We designed the extended event model based on the above design policies, and implemented this model as an encode/decode library for Windows Media. Based on this model we developed a video hypermedia system prototype and performed evaluation experiments. The evaluation results of real time synchronization performance of the system prototype showed that in - the case of sports video content a synchronization accuracy of 100 msec between video and metadata, makes our method effective for use in video hypermedia applications.
