MoCA arch rival Home PNA has been afforded the same status at the Digital Living Network Alliance (DLNA), and HPNA will be included in the next set of Networked Device Interoperability Guidelines. The DLNA is among the most influential organizations in the world for creating compatible communications stacks and had previously backed only MoCA and Wifi as acceptable standards to communicate video around the digital home.

The DLNA sees its role in bringing the backing of around 20 heavyweight players as voting members, and another 200 supporters, who pick standards which will best work together in the digital home and then provide a framework for interoperability testing and a use case for how all the technologies should work together. It doesn’t create standards, but it picks those that it likes and HPNA is now powerful enough to be irresistible, if the DLNA wants to remain relevant, given that HPNA says that it is currently shipping at a rate of 10 million chips a year.

Already the DLNA Certified logo has appeared on over 10,000 products from consumer electronics, mobile, personal computer, software, service provider, automotive and semiconductor industries. This announcement may perhaps be seen as an indirect endorsement of G.hn, which of course is not mature enough to make it into the DLNA stack, but as a follow on standard from HPNA this move positions it alongside MoCA and WiFi, and ahead of HomePlug, in terms of acceptance among interested equipment suppliers.

Nidhish Parikh, chairman and president of DLNA said “Certification of home networking technologies such as HomePNA is becoming an important component in the industry's drive to make networked equipment in the home work together.”

HomePNA says that to date some 20 million HomePNA chipsets have been shipped, worldwide and it is deployed in five continents and it has now been standardized by the ITU.

From the beginning the DLNA has tried to limit communication to only the most popular formats, and then convert to and from these formats automatically in a manner that works first time, every time. So while we all think Wi-Fi is cool and that it will eventually be a standard way of distributing video around a home, because today basic WiFi loses too many packets to be reliable with video, the DLNA has had to name some wired technologies and had solely gone for MoCA until now.
