The first global standard offering an in-home, high-speed network capable of delivering room-to-room HDTV has been agreed by ITU.
The standard, published under the G.hn banner, promises high quality multimedia over power, coaxial, phone and other home network wiring. It will give up to 20 times the throughput of existing wireless technologies and three times that of existing wired technologies.
The specifications will be used by chip manufacturers to build transceivers that can be incorporated into set-top boxes, residential gateways, home computers, home audio systems, DVD players, TVs or any other device that might be connected to a network now or in the future. Experts say that silicon companies will immediately start incorporating the specifications into transceivers, implying that G.hn-compliant products could be on the market as early as 2010.
Joyce Putscher, Principal Analyst at market research firm In-Stat, said, “Service operators have been looking for an international standard that encompasses multiple existing-wire mediums for video distribution. G.hn meets that requirement and it seems clear that with significant industry backing from service providers, semiconductor and equipment vendors, and the fast rate at which the process is moving to achieve a standard, we will see first equipment by 2010.”
