What is DLNA Technology?

27 Feb

Getting content from your smartphone, TV or even PC is no longer a hassle. Thanks to DLNA technology that enables our gadgets to connect with each other, wirelessly. Digital Living Network Alliance (DLNA) is a revolutionary technology that will turn your house to a “Digital Home”.

DLNA is an organization that was founded in 2003 by a group of global companies with the vision to let consumers easily connect their devices over a network for sharing digital content. The organization sets guidelines for home networking & media devices like TV, PCs, mobile phones etc that allows sharing of HD videos, photos, and other digital content between DLNA certified devices.

How Does It Work?

The first requirement of DLNA technology is that all the devices you want to connect together should be DLNA certified. You require a wireless home network with the help of which, all your devices will remain connected & you can easily access the digital content stored in these devices. There’s no involvement of cables or set-up procedures for using DLNA technology. If you want to watch a movie on big screen TV, but the content is stored in your DLNA certified PC, you simply have to select the movie & ask it to play on the DLNA certified media player that is attached to the TV.

What Can You Do With DLNA?

Watch Movies – So, you have captured a movie on your camcorder and have transferred it to your computer. And if you want to watch that movie on TV, you will normally burn a DVD & play it on the DVD player attached with the TV. If your devices are DLNA certified, all you will have to do is, search for the movie from the DLNA certified network attached storage and play it on your DLNA certified TV.

Photo Sharing – You can easily share your photos on DLNA certified devices like HDTVs or even PCs. Moreover, you can store these pictures on the network attached storage drives. If you want to take print-outs of these images, simply connect the device wherein these pictures are stored to a DLNA certified printer.

Music Sharing – So, you have downloaded a new track on your DLNA certified mobile phone and want to listen to it on your music system. If your music system is also DLNA certified, you will just have to choose the track & select the option to play it on the music system.
