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
3
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)
5
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
6
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

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
