SG 16 took note of the Final Report of the TSB Director’s Consultation Meeting on IPTV
Standardization, in particular of the intention of the TSB Director to create an ITU-T Focus Group
on IPTV (FG-IPTV) in accordance with Rec. A.7. SG 16 would like to show its strong interest into
the work of the new Focus Group on IPTV and intends to participate actively in this group.
In general, SG 16 considers that IPTV is a component of the so-called triple play services and
applications and is already addressing IPTV aspects under several Questions:
- For overall coordination matters, the contact point is the Chairman of ITU-T SG 16,
Mr Pierre-André Probst (under Q20/16).
- SG 16 has done and continues to do essential work in the definition of Media codecs. Thus
we would like to offer our experience and expertise on this topic. Contact points for Media
codecs are Mr. Paul Barrett and Mr. Thomas Wiegand.
- SG 16 continues to do essential work in the definition of a Multimedia Architecture (H.610,
ATM-based triple-play framework, including audiovisual requirements). Studies on an
IPTV architecture are now expected, taking into account the home network device
requirements. Thus we would like to offer our experience and expertise on this topic within
Q21. The contact point is Mr Bastien Lamer.
- SG 16 also notes that the topic of Security and DRM (Digital Rights Management) is
already investigated by Q25/16. SG16 shows strong interest to this topic in case of IPTV

and would like to get knowledge on your plans in this area. The contact point for security
and DRM is Mr. Martin Euchner, Rapporteur of Q25/16.
- Furthermore SG 6 has worked on Metadata and offers to contribute appropriately to the
IPTV Focus Group.
- Question 22/16 studies the consistent approach for various generic multimedia applications
and services taking into consideration also service aspects related to IPTV and would like to
get knowledge on the plans of FG IPTV. The contact point is Mr Noah Luo.
- Question 26/16 deals with accessibility matters and tries to ensure that new work takes into
account the needs of all users including those with disabilities. In the case of IPTV this topic
may include the provision of mechanisms to transmit and display captions, support for audio
description etc. Q26/16 will be happy to provide assistance with accessibility matters. The
contact point is Mr Bill Pechey, Rapporteur a.i. of Q26/16.
Annex A reproduces the list of topics drafted at the consultation meeting with references to SG 16
work. For this reason, it is important to coordinate the future activities of the FG IPTV with the
ongoing work in SG 16.
Generally SG 16 would like to note that all work done by the IPTV Focus Group shall consider the
activities on IPTV in other sectors of the ITU (e.g. ITU-R) and shall be coordinated appropriately to
achieve best possible work results and to avoid any redundancy.
