TRANSFORMATION AND EXCHANGE OF MULTIMEDIA OBJECTS IN DISTRIBUTED MULTIMEDIA SYSTEMS

One of the challenges in the design of a distributed multimedia system is devising suitable specification models for various schemas in diff erent levels of the system. Another important research issue is the in tegration and synchronization of heterogeneous multimedia objects. In this paper, we present our models for multimedia schemas and transform ation algorithms. They transform high-level multimedia objects into sc hemas that can be used to support the presentation and communication o f the multimedia objects. A key module in the system is the Object Exc hange Manager (OEM). In this paper, we present the design and implemen tation of the OEM module, and discuss in detail the interaction betwee n the OEM and other modules in a distributed multimedia system.
