At the June 2007 meeting of ITU-T SG15, work continued on a draft new Recommendation to develop a single international standard for home networking transceivers using any metallic media in the home – phoneline wiring, data cable (e.g. CAT5), coaxial cable or powerline wiring.
Household connectivity is growing rapidly with more and more electronic devices and networks within the home distributing and using digital information and media. In addition, remote control of lighting, heating, appliance-use and security systems attached to the home are making the "digital home" a reality.
International standards that enable interoperability and security in the field of home networking are seen as key to bringing value and versatility to consumers, making possible the use of diverse products, services and sources, and therefore accelerating market development.
Work in ITU-T is coordinated by the Joint Coordination Activity on Home Networking (JCA-HN). Topics covered across the 13 different Study Groups of ITU-T include digital rights management (DRM), phone-line networking (including co-ax), IPTV, interactive video, set top box architecture and cable modems.
The work on ITU-T Rec - G.hn - next generation home networking transceivers - has now attracted a critical mass of contributors/participants with nine companies submitting 20 contributions on various topics. It is anticipated that G.hn will be completed in 2008.
Also at the June 2007 meeting of ITU-T SG15, it was agreed to start work on a draft new Recommendation G.hnta on home network transport architecture. The Rec will give a generic architecture based on the NGN functional architecture described in Recommendation Y.2012 “Next Generation Networks – Frameworks and functional architecture models” It will describe a platform for the development of future home network standards. The draft Recommendation G.hnta is complementary to draft Recommendation H.ghna currently under development by SG16.
