Adaptive content model for distance education

Multimedia presentation systems require flexible support for the modeling of multimedia content models. Many presentation systems provide the synchronized, sequential or concurrent, and possible interactive, transfer of streams multimedia data such as audio, video, text and annotations using with network facilities. However, our through investigation of exist standards and applications for multimedia documents models such as HTML, MHEG, SMTL, HyTime, RealPlay and MS Windows Media let us to find that these standards and applications 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 the multimedia presentation authoring processes in terms of methodology and commercial aspects.
