Abstract
The CORBA audio/video (A/V) Streaming Service has been designed to implement and integrate open distributed multimedia applications. In this paper, a set of impairments resulting of the original A/V service are identified. To overcome such limitations, we propose an extension to the specification of the A/V Streaming Service. It defines a flexible architecture creating a framework that simplifies the implementation of applications handling audio/video flows. To evaluate our service extension we develop middleware objects of an application to control and manage uncompressed video data flows with strict time restrictions. Empirical results obtained by executing this application are also presented and discussed.
