Abstract

Every conceptual temporal rat relationship can be described using one of seven relations (before, meets, overlaps, during, starts, finishes, and equals ). The conceptual representation provides an efficient means for our multimedia authoring system to automatically fill in the necessary timing details. We developed a multimedia Presentation authoring system that supports a mechanism for conceptually representing the temporal relations of different media. Among the many editors that make up our system, the temporal relation editor provides users with an intuitive mechanism for representing the conceptual flow of a presentation by simple and direct graphical manipulations. Our system is based on the SMIL(Synchronized Multimedia Integration Language). The conceptual temporal relation editor and other editors of our system exchange their information in real-time and automatically generate SMIL codes through the SMIL Object Manager. Our system uses TRN(Temporal Relation Network) as its internal multimedia presentation representation. The TRN corresponds exactly to the structure seen in the graphical representation of the presentation. A parallel relationship found in a TRN can be collapsed into a single synchronization block. This facilitates the determination of the playing time of each component and can be the basic unit for reusability of already prepared blocks of presentation code.
