DLNA is also a standard which allows various devices from different manufacturers to share pictures, videos, and music, over a common network. These days, the word DLNA has become synonymous to wireless streaming of content over a home network. Here are some FAQs about DLNA. Is my device DLNA certified? There are hundreds of millions of DLNA-certified devices in the market currently. So, if you bought your device recently, then there is a very high probability for it to be DLNA certified. If you see a DLNA logo on the device packaging, or if your device shows up in the DLNA product search, then your device supports DLNA technology. How does it work? Now, let's discuss how media streaming is done between DLNA-certified devices. The first and foremost requirement is that the devices, which need to share media among themselves, should be in the same network. DLNA technology employs the use of Universal Plug and Play (UPnP), and supports 3 types of devices: Home Network Devices, Mobile Handheld Devices, and Home Infrastructure Devices. Home Network Devices and Mobile Handheld Devices consist of the following devices and their mobile counterparts. Home infrastructure devices, as the name suggests, act as a bridge between home network devices and mobile handheld devices. If required, they also convert and make media files compatible with home network devices, and mobile handheld devices. How to use DLNA technology? In order to stream media files on your TV, you need to have a DMS, DMC, DMP, and DMR. The good news is, if you have bought your DLNA TV and smartphone (iPhone excluded) recently, then all you need is a digital media server. And guess what? You already have a server in your home. You can use Plex, TVersity, Twonky, and many other software to turn your home computer into a DMS. If you are using Plex on computer, then also install its smartphone app on your mobile phone. Now, connect these devices to your home network, and you should be able to stream any movie/music you want to your TV, using your smartphone. Sometimes, unsupported file formats and DRM (Digital rights management)-protected content will cause hindrance in seamless media playback, but you can deal with them by processing your content with other third-party software.
