Formal Description and Presentation of Interactive Multimedia

An interactive multimedia presentation system is usually composed of present flow and present content. Generalized transition network (GTN) is used to describe control flow as formal description in the system. Based on the presentation context and presentable object, the method to describe present content is proposed. This method can be used to design an authoring tool for interactive multimedia presentation system. The system produced by the tool can present the multimedia content concurrently, and its component can be reused in other presentation system.
