Study Group 17 meeting in Korea, April, gave final approval to the Question on Internationalized Domain Names (IDN) that provides direction and focus to ongoing work. 

The news comes as ITU makes final preparations for the Global Symposium on Promoting the Multilingual Internet it is convening together with UNESCO, 9-11 May. 

ITU-T was mandated to work on IDN at the 2004 World Telecommunication Standardization Assembly in Brazil. IDN will contribute to easier and greater use of the Internet in those countries where the native or official languages are not represented in ASCII characters.

Andrzej Bartosiewicz, representing Poland and acting as Rapporteur for IDNs said: “We have received a number of contributions in this area and have been impressed with the level of interest and the productive nature of discussions. There are a number of organizations working in the field and I believe coordination will be an important focus of any work. The upcoming workshop will be a particularly useful tool for facilitating networking between experts in the field and furthering the study in general.”

Bartosiewicz said that a webpage will be published shortly with news on ITU-T study in the area, as well as related events and technical documents. An official ‘circular letter’ will be sent sent to Member States he said, requesting information about their experiences on the use of IDN. Given the response to this communication SG 17 will be able to better assess the current situation and needs.

The first meeting of the Focus Group on IPTV (FG IPTV) will take place 10-14 July in Geneva.

The official announcement is here, and a new webpage has gone live detailing how to participate, significant dates and news among other details.

FG IPTV will 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. It is open to any individual from a country which is a member of ITU who wishes to contribute to the work.

A new standard extending support of a key communications tool for the deaf and hard of hearing to IP-based networks was consented at a recent meeting of ITU-T’s Study Group 16. The continued support of textphones (TTYs) as operators increasingly shift to IP is important for the many thousands of users of these systems.

The announcement marks a key milestone in the development of what ITU terms Total Conversation, that is the convergence of voice, video and text telephony.

The new standard known as ITU-T Recommendation V.151 relates to text over IP (ToIP). ToIP is the transport of real-time text over IP networks. It differs from instant messaging in that ToIP systems transmit bi-directionally, one character at a time. This gives the user the feel of real-time communication, just like voice or video systems that transport streaming media over IP.

ToIP services are available using a legacy textphone (TTY) which has long been the preferred tool of the deaf and hard of hearing, an enabled IP phone or a PC-based client.

V.151 has an important role to play in the protection of text quality when transported through IP networks, also offering the potential to enable communication between earlier incompatible textphones from different regions.

Work in the video coding space progressed, following meetings taking place in Geneva in April.

Also, the beginning of the month saw the Japan launch of a new mobile terrestrial digital audio/video broadcasting service using H.264 and called "1seg".  The video compression standard (full name ITU-T Rec. H.264 or MPEG-4 pt.10/ AVC) jointly developed by ITU-T SG16 and the ISO/IEC Moving Picture Experts Group (MPEG) is now being deployed in products from companies including Apple, Sony, BT, France Telecom, Intel, Motorola, Nokia, Polycom, Samsung, Tandberg and Toshiba and in services such as over-the-air broadcast television, the new HD DVD and Blu Ray disc formats, and a large number of deployments of direct-broadcast satellite-based television services.

In Geneva, a new Recommendation was consented that will allow the use of a ‘back channel’ to convey the level of loss or corruption in video messages and if necessary apply measures to compensate for that. So, for example, at the content delivery end, an encoder, upon determining that a message is not getting through properly, may decide to reduce the message to its bare essentials resulting in a lower fidelity for the end user. Alternatively, the encoder and decoder can deploy intelligent recovery mechanisms. This will better support Recommendation H.264’s use in environments that may be more susceptible to error, for example in mobile telephony and IP-based video conferencing.

The new Recommendation has been drafted in such a way that it can be applied to existing (e.g. H.262, H.263, H,264) and future video coding standards. 

The work took place during co-located meetings of the Joint Video Team (JVT) and ITU-T Study Group 16, home of media coding work in the ITU. Over 90 documents were considered by the JVT group, which is the ITU-T and ISO/IEC joint project to enhance standard video coding performance, and is home to H.264/AVC.

An amendment to H.264 added support of new extended-gamut colour spaces, which are recently-specified enhanced methods of measuring and representing the brightness and color of the objects in video pictures. Also, in relation to H.264, work continued on developing new profiles supporting H.264’s use in high-end studio applications that use the 4:4:4 color sampling system and on developing scalable video coding (SVC) extensions of the standard as well.

ITU will take the lead in international standardization for IPTV with the announcement that it is to form a Focus Group on IPTV (IPTV FG).

The announcement, while acknowledging that standards work is ongoing in many different places, including ITU, is a reaction to an industry call for ITU to push forward and coordinate global standardization effort in the field.

IPTV is a system where a digital television service is delivered to consumers using the Internet protocol over a broadband connection. It will help pave the way for players, many of whom are already moving to IP-based NGN infrastructure, to offer a triple-play of video, voice and data.

Standards are necessary in order to give service providers, whether traditional broadcasters, ISPs or telecoms service providers, control over their platforms and their offerings. Standards here will encourage innovation, help mask the complexity of services, guarantee QoS, ensure interoperability and ultimately help players remain competitive.

The mission of IPTV FG is to coordinate and promote the development of global IPTV standards taking into account the existing work of the ITU study groups as well as SDOs, fora and consortia.

The group was launched following a decision taken at a public consultation meeting attended by around 120 experts from the world’s ICT companies. Attendees agreed that all players in the IPTV value chain will benefit from worldwide standards, that there is a lot of work to be done and that rapid progress is necessary in order to avoid market fragmentation. The Focus Group mechanism was seen as the most effective way of addressing this. Inputs to the meeting as well as a webcast can be found here.

Houlin Zhao, Director of the Telecommunication Standardization Bureau of ITU: “We have seen a desire to expedite and accelerate a global focus on standards for IPTV. There has been extraordinary consensus that ITU must lead this work and I am pleased that – again - ITU is seen as the right place to develop and harmonize this international standardization work, as well as identify and help fill gaps where there is still a standardization need.”

Bilel Jamoussi, Director Strategic Standards, Nortel, said: “Industry applauds ITU’s initiative to create this Focus Group and will contribute to its success.”

The FG will build upon existing work. Its scope will include architecture and requirements, QoS, security, network and control aspects, end system aspects – terminals etc., interoperability, middleware and application platforms.
