A distributed object platform for multimedia applications

Two current trends in distributed completing are the emergence of standardised distributed object platforms such as CORBA, and the increasing use of continuous media data types. This paper describes and evaluates a platform which supports both standard CORBA interactions and continuous media interactions in a fully integrated environment. The platform is implemented as a self-contained support infrastructure (GOPI core) and a separate 'personality' that sits an top of the infrastructure and provides a CORBA API. The platform user can create both request/ reply oriented and stream oriented bindings with quality of service specifications that are honoured (as far as possible) by the infrastructure, The level of performance attained by the platform provides evidence of the feasibility of natively supporting continuous media in a distributed object platform environment.
