Towards Virtual Audio/Video Environments Using Semantic Service Composition on a Service Oriented Infrastructure

The paper illustrates an open comprehensive distributed framework for audio/video applications which is based on service oriented architecture. The presented architecture not only introduces a high level of transparency on networked environments, it also supports some important system attributes such as reusability, maintainability, flexibility and availability. In this approach each functional unit is considered as a service and each desired scenario is accomplished through dynamic integration of these services using the existing network protocols regarding prescribed system ontology. Since the proposal follows a semantic manner from main concepts to low level components, it can be mapped to other distributed applications to provide different virtually integrated composites. The proposed approach is explained through overall models of audio and video applications and some example scenarios. The paper also studies and compares the available service oriented implementation tools and illustrates the actual implementation process.
