Will DLNA certification revolutionize home theater projectors?

Picture it: at your next movie night, you wirelessly stream a movie from your Blu-ray player to your projector. Afterward, you punch up a funny YouTube clip on your smart phone and, with the press of a button, the video appears on your projector. When it’s over, you whip out your new digital camera and share photos from your recent vacation on your projector.

All this was done without leaving the couch. Without changing cables and inputs. Without the need for extra equipment.

Welcome to what the Digital Living Network Alliance (DLNA) sees as the future of home theater.


The DLNA was founded in 2003 with the goal of using standards-based technology to make it easier for consumers to share their digital content between networked consumer electronics, PCs and mobile devices.

Currently, there are more than 9,000 DLNA-certified devices on the market today including TVs, storage devices, mobile phones, cameras, printers, game consoles, PCs, photo frames, media adapters, set-top boxes, AV receivers and Blu-ray disc players. DLNA insiders forecast that the number of certified gadgets will rise to nearly one billion by 2014.

How DLNA devices work

DLNA.org used this example to illustrate how DLNA-certified devices can simplify sharing home video:

“You recently downloaded your daughter’s birthday party video from your digital camcorder to your PC, and stored it on your DLNA Certified network attached storage (NAS) drive. Now you want to share it with your parents who are visiting. Step one: Use the TV’s remote to call up the video on your DLNA Certified TV. That’s it. No step two.

Before DLNA: You probably had to burn a DVD of that video, taking hours, or you had to hook up the camcorder to the TV to watch it, fiddling with messy cables that are never where you thought you put them.”

DLNA and projectors

LG is the first projector manufacturer to incorporate the DLNA standard with its soon-to-be-released LG HX350Y and LG HW300T. No word when these DLNA-certified projectors will hit the market, or whether other projector manufacturers will also adopt this certification.

However, many top brands, including Samsung, Sharp and Sony, are DLNA members. In theory, it should only be a matter of time for these brands to extend the certification to their projector lines.
