Digital Living Network Alliance

Digital Living Network Alliance (DLNA) (originally named Digital Home Working Group [DHWG]) was founded by a group of consumer electronics companies in June of 2003 to develop and promote a set of interoperability guidelines for sharing digital media among multimedia devices. DLNA works with cable, satellite and telecom service providers to provide link protection on each end of the data transfer. The extra layer of security allows broadcast operators to feel good about enabling consumers to share their content on multimedia devices without the risk of piracy.As of June 2015 the organization claims membership of "more than 200 companies".

The group published its first set of guidelines in June 2004. The guidelines incorporate several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, and widely used digital media formats and wired and wireless networking standards.

As of October 2015, over 25,000 different device models have obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices. It was estimated that by 2017 over 6 billion DLNA-certified devices, from digital cameras to game consoles and TVs, would be installed in users' homes.
