碩士 === 淡江大學 === 資訊工程研究所 === 83 === In this thesis, we introduce a "Multimedia Object Composition Model"(MOCM). This model includes a script language specification that is used to describe the spatial and temporal composition relationships among multimedia objects. This model also has a preprocessor to translate users' description into host language. The preprocessor parses the scripts and generates a spatial and temporal relation table of all objects. Then through this table, preprocessor can generate an executable program. For multimedia application designers, they can use the tools provided by this system with host programming language ( ex. C, C++ ) to write multimedia application systems easily. For example, we can develope multimedia presentation systems, multimedia explanations, CAI and so on. The MOCM's media object class hierarchy we developed is an open ended architecture. It hides the implementation details from users. Currently, we only support three types of media : audio, video, and text. If a user want to include another type of MOCM's media object, he only have to inherit suitable super class given in the frameworks to create a new class, and just call the library functions associated with new media.
