A service-oriented multimedia componentization model

As Web services become more and more popular, how to manage multimedia Web services that can be composed as value-added service solutions remains challenging. This paper presents a service-oriented multimedia componentization model to support Quality of Service (QoS)-centered, device-independent multimedia Web services, which seamlessly incorporates cuttingedge technologies relating to Web services. A multimedia Web service is divided into control flow and data flow. Each can be delivered via different infrastructures and channels. Enhancements are proposed to facilitate Simple Object Access Protocol (SOAP) and Composite Capability/Preference Proflies (CC/PP) protocols to improve their flexibility to serve multimedia Web services. We present a set of experiments that show the viability of our service-oriented componentization model that can support efficient delivery and management of multimedia Web services.
