Foreword This Technical Specification (TS) has been produced by ETSI Technical Comm
15、ittee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). The present document defines the TISPAN NGN Release 3 IPTV architecture: Integrated subsystem for IPTV functions in NGN. Introduction The present document provides an architectural framework for
16、the end-to-end Internet Protocol Television (IPTV) subsystem within the Next Generation Networks architecture. The IPTV framework is designed for interoperability with other NGN service subsystems and components. The present document identifies functional entities and reference point, which needs to
17、 be exposed from IPTV subsystem. ETSI ETSI TS 182 028 V3.5.1 (2011-02)71 Scope The present document describes the IPTV functional architecture and functions of an NGN Integrated IPTV system by integrating of IPTV functions into the NGN architecture. For example, interactions and information flows be
18、tween the IPTV functional entities and other functional entities will be specified. The specification starts from outlining high-level IPTV functional architecture, functional groups and is further developed into the more detailed functional architecture, reference points and operational modes. The
19、architecture is intended to support requirements defined by the respective ETSI TISPAN requirement definitions 1 and allow integration new or existing IPTV solutions (such as those defined by DVB, ATIS IIF, ITU, etc.) within the NGN architecture. The resulting architecture should, should rely as muc
20、h as possible on common components and integrates, coexist with other TISPAN NGN services. The following areas are covered: Authentication and authorization. Content Protection (including DRM). Capability exchange. Resource Management. Policy Management. Charging. User Profiles. The architecture foc
21、uses on closer integration between IPTV services and NGN networks, migration scenarios from existing solutions (i.e. DVB-IPI, ATIS-IIF) into NGN and common components. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-speci

The support for other NGN services has a wide meaning, e.g. the functional architecture would allow coupling functionality of IPTV subsystem with functionality
47、of PES or IMS subsystem, which in-turn may support some IPTV features as defined in 6. In order to achieve high level of flexibility, the work is focused on identifying and standardizing functional entities and reference points, which needs to be exposed from IPTV subsystem to the rest of NGN. Inter
48、nal IPTV functional entities and reference points are identified and described for the completeness of the end to end architecture without intend to standardize them. The architectural approach considers IPTV subsystem as a functional area, which is integrated into NGN via standardized reference poi

The IPTV integrated subsystem is based upon IPTV domains defined in TS 181 016 1, clause 4.1 IPTV Roles. 4.2 High Level Architecture Overview Figure 1 presents high-level NGN IPTV functional overview and location of IPTV capabilities in the TISPAN NGN.
