DLNA is a way for multimedia devices to communicate with each other on a local network. DLNA-compliant devices can stream local video, audio, and picture files to each other over your network.
It's a way for your TV to stream videos from your media server and your smartphone to act as a remote that can play a file from one device on another device. That's the idea behind DLNA, anyway. These devices use a standard protocol to talk to each other. Rather than each manufacturer creating a proprietary protocol for streaming media files on a network, DLNA-compliant devices can communicate with each other.
You can buy a device from one manufacturer and use it with a device from another manufacturer, even if those two devices were never tested together. Many devices support DLNA. DLNA software is available for a wide variety of platforms. DLNA divides devices into different classes. For example:. This isn't a complete list -- DLNA also defines other device classes, including different types of handheld devices.
For example, you could use the Play To option in Windows Media Player to a play a local video file to an Xbox or other game console. Your PC would notice the game console, display it as a possible playback destination, and then tell the game console to start streaming the video when you press play.
You have an old hi-fi device without support for AirPlay, Chromecast or other modern streaming technologies. Or a set of active speakers with limited support for streaming services. Throw away? Because yes, you can safely call DLNA the dinosaur under the streaming technologies.
It is very old and even the underlying organization with members such as Intel, LG and Samsung has been discontinued. DLNA was developed at the beginning of , at a time when playing a media file over the network was still quite challenging.
There was then no question of streaming services. You consumed music or video in the form of your own files. So it is a technology designed to play a file that was somewhere on your network for example on a NAS on another device an audio device or television, for example.
Determining which specific media file you are playing is done by an app called the controller. Often that function is immediately embedded as a function in the device on which the media would play. Controller and player are then united in one place. This is the case, for example, with televisions or AV receivers.
The threefold nature — server, controller, player — may seem incredibly complex today. Compare it with Chromecast, AirPlay or Spotify Connect, three newer streaming techniques that automatically detect speakers and make it very easy to play music elsewhere. But the more complex nature of DNLA does create an opening to abuse the technology so that you can still play music from streaming services. Invest a few euros in the right app and it is possible. This way of streaming over DLNA is not only relevant for old hi-fi devices.
There are also new products that may not support your favorite service. BubblePnP is one of the best known media player apps for Android and also one of the oldest. The developer behind the app is very active and regularly adds new functions. That makes this app really a Swiss army knife in terms of media playback. It is also able to cast your own files to Chromecast adapters and Android TV devices for example, which can be useful.
It also plays smoothly to Sonos speakers. In addition, it is packed with functions that are quite practical. For example, the app makes it very easy to send videos that were made with your smartphone to a TV or to present photos that are in Google Photos on the big screen.
