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. the organization claims membership of "more than 200 companies".
