Content  What is IPTV?  Why IPTV?  IPTV domains and architecture  The focus group on IPTV (FG IPTV)  The IPTV global standards initiative (IPTV-GSI)  Concluding remarks Colmbo, Sri Lanka, 7-10 April

What is IPTV? IPTV is defined as multimedia services such as television, video, audio, text, graphics and data delivered over IP- based networks which are managed to support the required level of QoS/QoE, security, interactivity and reliability Colmbo, Sri Lanka, 7-10 April IPTV is NOT only television over IP  it is much more 

Why IPTV? Colmbo, Sri Lanka, 7-10 April Video/ television services Voice services Data services The intersection of any of these domains creates new service opportunities Increased service value Increased customer loyalty Increased ARPU Web and PC on TV Video on PC VoIP Voice services on TV Video phone

What is IPTV Offering?  NGN has opened up new possibilities, enabling user control and involvement. IPTV is envisaged to be the major beneficiary of NGN providing numerous capabilities for video, audio and data applications (i.e. triple and quadruple plays) Colmbo, Sri Lanka, 7-10 April New integrated services represent the real opportunity for service providers to differentiate their offerings

IPTV Domains Colmbo, Sri Lanka, 7-10 April

Architectural View: Technology Colmbo, Sri Lanka, 7-10 April IPTV provides the end-to-end solution! Content Ctl & mang CoreEnd-UserAccess Encoders Middleware VoD servers Content aggregators DSLAMs Access gateways FTTH Residential gateways Modems Set-top boxes Mobile devices Home network Transport Content Routing Switching

IPTV Domains (I)  End-user (consumer) Selects and consumes content Pays bills Has network connection with LAN QoS Owns or operates IPTV terminal Set-Top Box connected to a TV Soft-client on PC or game console Colmbo, Sri Lanka, 7-10 April

IPTV Domains (II)  Network Provider: Delivers content (e.g. stream) from Service Provider to Consumer Network Transport Multicast streams – one to many Unicast streams – one to one Point-to-point IP connectivity Network Authentication Normally provided by home gateway Network Upstream & Downstream Control Admission control Traffic prioritisation Network Session Multicast – long duration, maintained across channel changes Unicast – duration same as content use Colmbo, Sri Lanka, 7-10 April

IPTV Domains (III)  Service Provider Provides IPTV service Ingests and protects IPTV content Responsible for operational and business support systems CRM, fulfilment, assurance, configuration, billing, etc. Provides IPTV application Content identification, selection, purchase, etc.  Content Provider Owner of content Delivers contents as: streams, files, tapes, etc. Responsible for production, contract management, encoding, etc. Colmbo, Sri Lanka, 7-10 April

Colmbo, Sri Lanka, 7-10 April First step in ITU for a harmonized global solution for IPTV Focus Group on IPTV (FG IPTV)

FG IPTV Mission Statement  Coordinate and promote the development of global IPTV standards.  Take into account the existing work of the ITU study groups as well as other Standards Developing Organizations (SDO), Forums and Consortia. Colmbo, Sri Lanka, 7-10 April

Areas of Standardization  Architecture and requirements  QoS/QoE and performance  Service security and content protection  Network and control  End systems and interoperability  Middleware and application platforms Colmbo, Sri Lanka, 7-10 April ITU-T is committed to producing global standards for an end-to-end IPTV solution

Collaboration With Other SDOs  Liaised with most SDOs involved in development of IPTV related standards  Used ATIS IIF, Broadband forum (formerly DSL Forum) and Home Gateway Initiative related documents as input to prepare ITU-T standards  Good working relationship with DVB project and ETSI TISPAN Colmbo, Sri Lanka, 7-10 April Regional and national bodies and related SDOs benefit immensely from contributing to ITU-T and having their work incorporated into globally recognized and accepted standards.

Focus Group on IPTV - Key Facts  Established: April 2006  Held 7 face-to-face meetings: Every 25 months  Contributions received:1101  Average participation per meeting:178  Deliverables: 20 Architecture and requirements4 QoS and performance4 Security1 Network control3 End systems and interoperability2 Middleware and application platforms5 Terminology1  Terminated:January 2008 Colmbo, Sri Lanka, 7-10 April

IPTV Focus Group Proceedings  FG IPTV Proceedings are available for free download: IPTVFG-2008/en Colmbo, Sri Lanka, 7-10 April

IPTV Global Standards Initiative Colmbo, Sri Lanka, 7-10 April

IPTV Global Standards Initiative (I)  After termination of the FG IPTV mandate, the ongoing work on IPTV was carried out under the umbrella of a Global Standards Initiative (the IPTV-GSI) The focus group output documents were distributed between relevant study groups. Coordinated planning of the activities through co-located meetings of the involved Rapporteur groups. IPTV-GSI is now comprised of study groups 9, 11, 12, 13, 16 and 17. These study groups collaborate with most of ITU-T study groups Colmbo, Sri Lanka, 7-10 April

IPTV Global Standards Initiative (II) Colmbo, Sri Lanka, 7-10 April  Created the IPTV-JCA (Joint Coordination Activity) To oversee IPTV-GSI activities Extends representation to include other SDOs involved with ITU-T in the IPTV work stemming from the results of the IPTV Focus Group  Convened five meetings in 2008 and some are planned for 2009  Has produced the first set of global

IPTV-GSI Documents Colmbo, Sri Lanka, 7-10 April IPTV-GSI documents are available at: Note: a TIES account is required to access these documents

Practical Considerations Colmbo, Sri Lanka, 7-10 April

Architecture Approaches Colmbo, Sri Lanka, 7-10 April  “ NGN-based” and “IMS-based” architecture An IPTV service component is drawn on top of “other NGN service components” in NGN architecture. The IPTV service component is achieved by using IMS  “NGN-based” and “non-IMS-based” architecture An IPTV service component is drawn on top of “other NGN service components” in NGN architecture The IPTV service component is achieved without using IMS  “Non-NGN-based” architecture The architecture does not depend on NGN architecture

IPTV Functions Colmbo, Sri Lanka, 7-10 April Content Delivery Functions Manage- ment Functions Application Functions Service Control Functions End-User Functions Content Provider Functions Network Functions

Implementation Approaches  Operators can choose different approaches for IPTV deployment: 1. Build IPTV service using a set of components from different suppliers, that suppliers integrate themselves. 2. Build IPTV service with a pre-integrated set of components; integrator and component suppliers. 3. Build IPTV service with an integrated set of components for a single supplier. Colmbo, Sri Lanka, 7-10 April ITU-T is engaged in the standardisation of interfaces between IPTV components.

Concluding Remarks (I) Colmbo, Sri Lanka, 7-10 April  ITU-T responded quickly to market needs for producing standards on IPTV  ITU is cooperating with other SDOs and industry forums to produce global standards  First set of Recommendations (i.e. standards) have been approved and probably are being implemented  ITU-T is a unique place where global IPTV standards can be created  ITU-T IPTV standardization success comes from addressing all IPTV related issues and having all IPTV experts at the same time and in the same place  Work continues at full steam to complete and complement recently created standards Providing ITU-T standards compliant products would benefit all involved.

Concluding Remarks (II) Colmbo, Sri Lanka, 7-10 April Compliance to global standards would:  Reduce development costs and product costs  Result in capturing bigger market share  Bring faster introduction to the markets  Ensure interoperability  Help all players remain competitive ITU-T standards compliant products are key to global interoperability
