The field of distributed systems is now entering a stage of maturity with work focusing on standards for Open Distributed Processing (ODP). However, it is still important that standardisation remains responsive to emerging technological demands such as the emergence of distributed multimedia computing. This new field introduces continuous media data types(More)
Reactive scripts are designed to get a exible approach for responsive systems; they are based on the reactive/synchronous approach, well suited to real time programming. A reactive script interpretor is a broadcast event-driven interpretor which can react to several commands in parallel. Generating events and waiting for occurrence of events are the basic(More)
This paper presents a Java-based reactive programming framework well adapted to the construction of complex behaviors for CG objects within virtual environments. This reactive approach is based on an instantaneously broadcast event model and a semantically-sound synchronous/reactive formalism. The reactive framework degree of expressiveness is illustrated(More)
There is currently considerable interest in developing multimedia applications in open distributed systems. However, it is now becoming clear that existing architectures for open distributed systems do not support the particular requirements of continuous media types such as digital audio and video. This is particularly the case in the important areas of(More)
