Layered design of CORBA audio/video streaming service in a distributed Java ORB middleware multimedia platform

The present work practices a previously published layered middleware design architecture that can integrate a rich set of Java APIs into the OMG CORBA audio/video streaming framework. In this design, JMF, CORBA audio/video streaming service, CORBA, and JRE are functioned as a programming language domain-specific middleware, a common middleware service, a distribution middleware, and a host infrastructure middleware layers, respectively. The current work utilizes the OMG audio/video stream binding mechanism in order to provide a standardized interoperability of streams between CORBA and JMF environments. Through a generalized mapping, CORBA objects could directly manipulate JMF classes. Although the current high level layered design work is only applicable to OMG compliant Java ORBs, this design concept could be extended into other language specific ORBs by utilizing other programming language domain specific service layers, i.e., other programming language APIs.
