• Hypermedia systems are very important as platforms for the multimedia information network service spaces in the future. In order to provide more flexible and sophisticated multimedia presentations, it is desirable to simply and efficiently transmit various media data from databases distributed over a network and present them on users' stations depending on a customized presentation scenario so as to semantically integrate them into multimedia information objects. In this paper, we introduce a new hypermedia system that utilizes an object-oriented structure to perform two different temporal synchronization methods, lip synchronization and scene synchronization. The lip synchronization method performs fine-grained temporal synchronization between continuous media, such as audio and video. In the scene synchronization, a coarse-grained temporal relationship between continuous media and discrete media, such as image, graphics or text is maintained depending on the presentation scenario. Furthermore, several media which are semantically related to each other are unified into a Media Group (MG) to simplify their media treatment. The MGs and their involved processing functions are encapsulated into a Media Object (MO) and are easily controlled by a message passing procedure. In this paper, we describe in detail implementation of a hypermedia model which performs scene synchronization functions between discrete and continuous media in the MOs, and context switching functions between each media presentation. Finally the Electric Museum as a prototype application of hypermedia systems is introduced to evaluate the suggested synchronization mechanism.
