| Abstract: | According to features of Silicon Graphics workstations, the paper dissertates mainly the system construction and the key technique of multimedia authoring tool AUTHOR based on SGI platform. In the synchronization of media objects, the author adopts the time stream Petri net (TSPN) model to express the synchronization and mutual exclusion relations of the media data stream. Using the model and the software design method called "from top to bottom,refinement step by step" it describes the media express scheme of complex multimedia system. |
