ITU-T IPTV standards development DOCUMENT #: GSC13-PLEN-14 FOR: Presentation SOURCE: ITU-T AGENDA ITEM: Plenary 6.6 CONTACT(S): John Visser, ITU-T jvisser@nortel.com Ghassem Koleyni, ITU-T ghassem@nortel.com ITU-T IPTV standards development John Visser, Chairman SG 19 jvisser@nortel.com Ghassem Koleyni, IPTV-GSI TSR Coordinator ghassem@nortel.com International Telecommunication Union Submission Date: July 1, 2008

Highlight of Current Activities (1) April 2006: ITU-T created the focus group on IPTV (FG IPTV) to look at the end-to-end aspects of providing IPTV services Took into account existing work of ITU SGs, plus work of SDOs, Fora and Consortia: developed a set of deliverables in Dec 2007 Freely available at http://www.itu.int/publ/T-PROC-IPTVFG-2008/en FG IPTV deliverables were transferred to the relevant SGs as input to the development of new Recommendations With multiple SGs involved, the IPTV-GSI (Global Standards Initiative) was created to provide an overall home for the work A GSI is a package of work conducted through co-located meetings of the involved SGs and Rapporteur groups under the umbrella of a coordinated work plan managed by a JCA Questions (working groups) from different SGs meet co-located Meet more frequently than regular study group (five times in 2008)‏ Experts in all related fields meet together, expediting progress

Highlight of Current Activities (2) In response to market needs, the IPTV-GSI is aggressively developing the global standards to facilitate interoperability: IPTV services requirements IPTV architecture Quality of experience requirements for IPTV services Performance monitoring for IPTV Traffic management mechanisms for the support of IPTV services Architecture and functional requirements for Home Network supporting IPTV services Multimedia application platforms & end systems for IPTV IPTV Terminal Devices and End-System IPTV security aspects ITU-T is the focal point for global IPTV standards in response to market needs and to facilitate interoperability

Strategic Direction Be responsive to the global market need Developing standards which provide end-to-end solution for IPTV and facilitate interoperability Promoting and keeping liaison relationship with all SDOs and fora involved with the development of IPTV standards Incorporating as much content from national and regional standards into ITU-T standards, based on members consensus, thus helping interoperability Making global standards happen through collaboration, not competition In today’s environment, national/regional standards need to be supersets of global standards

IPTV-GSI achievements Consented three Recommendations Y.1910, IPTV functional architecture (SG 13, May 2008) G.1080, Quality of experience requirements for IPTV services (SG 12, May 2008) G.1081, Performance monitoring points for IPTV (SG 12, May 2008) Approved one supplement Supplement 5 to Y-series Recommendations, ITU-T Y.1900-series, Supplement on IPTV service use cases (SG 13, May 2008)

Challenges Timely completion of standards to meet industry / market needs Coordination with recognized SDOs to avoid duplicate standards Providing a set of standards that: Support end-to-end solutions Ensure interoperability between suppliers Ensure interoperability of services

Next Steps/Actions Complete the first sets of Recommendations Look to developing further IPTV related Recommendations Attention will be given to Recommendations which are indirectly related to IPTV but essential to its operation Revisit NGN-related Recommendations to ensure they fully support IPTV services

Supplemental Slides

IPTV functional architecture

Three architectural approaches “NGN-based” and “IMS-based” architecture An IPTV service component is drawn on top of the “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 the “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
