The convergence of telecommunication, cable TV, and broadcast networks towards the Internet technology will enable the provision of emerging multimedia services as well as the integration of rich communication capabilities with TV services. However, enabling efficient delivery of interactive personalized multimedia services with mobility support requires an advanced overlay control framework. The IP Multimedia Subsystem (IMS) offers the basic functions to manage multimedia sessions over different access networks. This paper outlines current standardization activities that address the provisioning of TV services over IP networks—known as IPTV—and proposes a novel end-to-end overall architecture based on IMS that enables the delivery of converged multimedia services. Furthermore, the paper presents the FOKUS Media Interoperability Lab as a reference implementation of this framework which covers a widespread spectrum of converged interactive scenarios. The final section gives an impression of the system performance by providing the end-to-end signaling delay of a session setup for live TV service delivered over unicast transmission mode.
