Multimedia Synchronization through Interactive Active Objects

This paper presents an Active Objects Model as an environment for the implementation and demonstration of key concepts in the emerging ISO/IEC Standard, PResentation Environments for Multimedia Objects (PREMO). The event-based synchronization mechanism which is a key concept in multimedia presentation is presented through a set of examples. The AOM model consists of a set of active agents with distributed rule based behaviours. One important facility is the description of trajectory based behaviour in direct manipulation technique. Key words: PREMO, multimedia presentation, agents, active objects, rule based behaviour, trajectory, event based synchronization. 1. Introduction The Active Object Model (AOM) has been developed at the University of Cluj-Napoca as a possible framework for the development of complex multimedia applications, visual programming environments, intelligent graphical user interfaces [8, 9], virtual reality, and courseware authoring [5, 6, 10, 11, 12]. An implemen..
