Video Presentation Model

Lecture-on-Demand (LOD) multimedia presentation technologies among the network are most often used in many communication services. Examples of those applications include video-on-demand, interactive TV and the communication tools on a distance-learning system, and so on. We describe how to present different multimedia objects on a Web-based presentation system. Using characterization of extended media-streaming technologies, we developed a comprehensive system for advanced multimedia content production: support for recording the presentation, retrieving the content, summarizing the presentation, and customizing the presentation. This approach significantly impacts and supports the multimedia presentation authoring processes in terms of methodology and commercial aspects. Using the browser with the Windows Media Services allows those students to view live video of the teacher giving his or her speech, along with synchronized images of presentation slides, and all the annotations/comments. In our experience, this very approach is sufficient to the use of distance learning environment.
