Digital Living Network Alliance (DLNA) expanded its Home Networked Device Interoperability Guidelines with new features and device classes, including mobile device connectivity, quality of service and printing. The guidelines define the architecture, protocols and media formats to create a Digital Living network encompassing consumer electronics, personal computers (PCs) and mobile products that share digital content over Ethernet or Wi-Fi(R).
DLNA (Portland, Oregon, U.S.) says Digital Living is based on the premise that CE, mobile and PC products should work together regardless of manufacturer and regardless of whether operating in the home, office or on the go. Initial DLNA Guidelines supported two core device classes: digital media server (DMS) and digital media player (DMP). Today, DLNA members from around the world can offer ten additional digital media device classes, including printer, renderer, controller, and mobile versions of these devices, such as mobile DMS and mobile DMP. Possible usage scenarios now include, for example, a networked TV sending print jobs to a printer. On the mobile side, a camera phone uploads and downloads files to and from a DMS on the home network.
DLNA is drafting guidelines to enable access to protected commercial content in the home network environment. The guidelines are expected mid-year.
"We understand that enabling products to 'talk' is only part of the solution," said Scott Smyers, chairman of the DLNA board of directors. "A major opportunity for industry manufacturers and content providers is the ability to protect the content being shared within the network. This is the next step toward broadening DLNA's applicability to include commercial content as well as personal media."
