    A Framework for Real-time Synchronization in Intelligent Media Generators

    Recent advances in computer graphics and multimedia technologies have contributed to the development of interactive media-rich systems that generate media elements dynamically in multiple modalities to present information in an effective and appealing manner to users. Utilizing media elements in an application that requires them to be temporally coordinated in real-time presents synchronization issues because the wrong timing or duration of media elements will be easily detected by the user. Most media-rich systems have solved various aspects of the media element synchronization problem. However, they have done so in an ad hoc manner without providing a generic reusable framework. This thesis proposes a framework for real-time synchronization in intelligent media generators. Our research addresses six primary issues that are essential to creating media-rich systems that do not utilize an ad hoc solution to their media element synchronization problems: synchronization of media elements, decoupling high-level and low-level processing, extensibility, media element sequencing, real-time performance, and domain-independence. The framework has been implemented in an agent-based multimedia generator for an intelligent tutoring system to demonstrate its feasibility.
