Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee 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 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 be exposed from IPTV
subsystem.

1 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 between 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 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 much 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 focuses 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.
