Dear WP2/16 experts,

The next meeting of SG16 (3-13 April, Geneva) is rapidly approaching. 
Your contributions are requested on the following topics among other 
things:

1/ Ongoing works

Annex 3 of Collective Letter 3/16 
<http://www.itu.int/md/T05-SG16-COL-0003/en> list preliminary items 
to be discussed during the meeting. The list is attached after my 
signature for your convenience.

2/ Requirements for the "H.325" system

We are continuing to identify what are required for the new 
generation multimedia communication system codenamed "H.325". How it 
should interwork with NGN would be one of the discussion items; what 
facilities of NGN we can utilize for our purpose, what facilities we 
would like to define inside the NGN service stratum, ...

3/ IPTV (relaying Mr. Probst's messages)

The TSB Director is organizing an informal consultative meeting on 
4-5 April 2006 (see TSB-Circular 71) 
<http://www.itu.int/ITU-T/IPTV/index.phtml>. Please note that this 
event will take place during the second and third day of our SG16 
meeting. It is likely that during this event, future work on the 
development of standards will be discussed  as well as the role of 
the different ITU-T Study Groups. Please note that the subject has 
already been discussed at the last GSI NGN event in January 2006.

It is my understanding, that IPTV should be considered here in the 
large sense of the term, that is distribution of TV programmes over 
IP on all kind of  platforms (xDSL, Fibre, cable, satellite, Wi-Fi, 
Mobile, etc...).

For SG16, there are two questions:
  a) What activities should we push in this field (e.g H.610 for IP, 
video codecs, ...)
  b) What role do we want to play in the coordination?

4/ Networked RFID (relaying Mr. Probst's message)

The workshop held last month 
<http://www.itu.int/ITU-T/worksem/rfid/index.html> was a success both 
in terms of the information given and the participation of experts in 
and outside ITU-T. I would like to encourage you to look at the 
presentations and in particular at the conclusions of the different 
sessions. You should pay special attention to the conclusions of 
session 7 <http://www.itu.int/ITU-T/worksem/rfid/program.html>, which 
contains a list of topics of common interest between the different 
players active in the development of global standards.
