A Service Oriented Architecture for Personalized Rich Media Delivery

Multimedia streaming means delivering continuous data to a plethora of client devices. Besides the actual data transport this also needs a high degree of content adaptation respecting the end users´ needs given by the form of content preferences, transcoding constraints, and device capabilities.When it comes to content editing (like mixing in subtitles or picture-in-picture composition) relying on third party service providers may be necessary. For improved efficiency all adaptation should be done in a service-oriented way, because a lot of adaptation modules can be reused within different adaptation workflows. In this paper we discuss the extensions of Web service frameworks, and present a first implementation of a service-oriented framework for media streaming and digital item adaptation, concentrating on the technical realization of the services. Our experimental results show the practicality of the actual deployment of service-oriented multimedia frameworks.
