ITU-T IPTV-GSI (Global Standardization Initiative)Develop Formal Global StandardsJoint, Co-Location Meeting


TSB Director's consultation meeting

TSB Director's consultation meeting on IPTV standardization (4~5 April 2006, Geneva)agreed to establish a FG-IPTV according to provisions of Recommendation A.7developed Goals of FG IPTV as starting point

Definition of IPTVIdentification of scenarios, drivers and relationships with other services and networksIdentify requirements and define framework architecture

Review and gap analysis of existing standards and ongoing worksCoordination of existing standardization activitiesHarmonization of the development of new standardsEncourage interoperability with existing systems where possible

sgkang-4



Mission of FG IPTVto coordinate and promote the development of global IPTV standards taking into account;

the existing work of the ITU study groups as well as Standards Developing Organizations, Fora and Consortia

Parent of the IPTV Focus Group: Study Group 13Joint Coordination Activity (JCA) had been established amongst the management of the concerned Study Groups

to provide an interface to the IPTV Focus Groupto ensure the smooth handover of the results of the focus group to SGs

The work of the IPTV Focus Group: ended in Dec. 2007Developed 20 Deliverables
