Abstract

Abstract:

With the tendency of convergence of telecommunications network,broadcast and TV network and Internet,IMS（IP multimedia subsystem）-based IPTV represents the evolutionary direction of IPTV development in the near future.International standardization bodies have been working on IMS to enable provision of IPTV services（IMS-IPTV）.This paper firstly presents the current standardization efforts of IMS-IPTV in ETSI TISPAN and ITU-T.Secondly,it presents the IMS-IPTV layered architecture and analysis based on the IMS-IPTV service characters.Fina11y,it provides analysis of the influence of IPTV services on IMS network.

Key words: IMS, IPTV, architecture, service, influence
