Adaptive content model for multimedia presentation

Multimedia presentation systems require flexible support for the modeling of multimedia content. Many presentation systems provide synchronized, sequential or concurrent, and possible interactive, transfer of multimedia data streams such as audio, video, text and annotations used with network facilities. However, our investigation of existing standards and applications for multimedia document models such as HTML, MHEG, SMIL, HyTime, RealPlay and MS Windows Media shows that these standards and application models do not provide adequate support for reuse and adaptation. Consequently, we propose a new approach for the modeling of reusable and adaptable multimedia content. We developed a comprehensive system for advanced multimedia content production: support for recording the presentation, retrieving the content, summarizing the presentation, weaving the presentation and customizing the representation. This approach significantly impacts and supports multimedia presentation authoring processes in terms of methodology and commercial aspects.
