A Constructive Type Schema for Distributed Multimedia Applications

Abstract

The constant evolution of multimedia technology puts strong requirements on the design of distributed multimedia systems if upgradability and extensibility are desired. A proposal for an object and a composition models based on a constructive type schema is described in this paper. Objects and compositions are aggregations of various small aspects to which the system reacts. As the system gets richer and more complete, new aspects can be easily added. Type information is left out of the objects and is used in the distributed system for various purposes. Simpler views of the models create environments where the construction of specific kinds of applications is easily performed. A visual editor is described for one of such views - distributed multimedia applications based on coarse temporal, spatial and logic synchronization.
