N2 - One of the major requirements of distributed multimedia applications is the need to maintain often complex, real-time synchronization constraints, More specifically, it is necessary to be able to manage arbitrary intra- and inter-media synchronization across activities in the distributed environment. Furthermore, it is important that such developments are integrated into emerging object-oriented standards for distributed computing. This paper presents an object-oriented programming model and associated implementation to meet these requirements. The main concepts behind the proposed approach are, firstly, the use of reactive objects for real-time control and synchronization and, secondly, quality of service controlled bindings for predictable communication between objects, The flexibility of the approach is demonstrated by three contrasting examples of real-time synchronization. The implementation extends the realtime capabilities of the Chorus micro-kernel by introducing the concepts of rtports, rthandlers and quality of service controlled connections, The paper demonstrates how reactive objects and bindings are realized on this infrastructure.
