4 TISPAN NGN IPTV architectures - comparing of
functionalities and services
When IMS based IPTV [i.1] is compared with NGN integrated IPTV [i.2] main differences between both solutions are
following:
• Separation of service selection and discovery in IMS based IPTV (SIP based discovery).
• Similar service selection specs, IMS based IPTV additionally support OMA BCAST ESG.
• SIP based service initiation and service control.
• Support of the direct RTP encapsulation.
• Related differences in interfaces and protocols (from Tr to Ut, Xa and change from http based Ct, Ss, Sa to SIP
based Gm, ISC, y2 interfaces).
