Combinational services of NGN based IPTV

This paper describes the general concept of combinational/blended services for IP-based Television (IPTV) services in next generation networks towards its service oriented architecture concept (SOA). Besides introducing general approaches of service reusability (SOA concepts), the service enables (e.g. presence, notification, messaging) as application service function in next generation networks will be outlined by standardization work in ETSI TISPAN and also explicit examples of prototypes are given. The extensibility will be elaborated within the IPTV subsystem and also as the possible interconnection with Web services. Selected cases have been successfully prototyped and deployed exemplary in the laboratory testbed.
