An event-driven system for distributed multimedia applications

We propose an architecture for distributed multimedia applications based on an event-driven programming model. To avoid the synchronization problems inherent to multi-threaded programming, the proposed architecture is based on a single-threaded structure. Instead of multi-threading, we opted for the event-oriented approach allied to multiple communication channels with user-defined handling procedures to allow the application to deal concurrently with control and data streams. We discuss this programming model, present the system we have implemented based on this model, and describe the experience we have had with this system.
