The Digital Living Network Alliance (DLNA) is a technology standard for connected devices and streaming media throughout the home. While the standard covers many differnt types of devices, the most well known are DLNA media servers (DMS) and DLNA media players (DMP). These two families of devices come together to allow one to stream over the home network multimedia content from some server device to some player device.
DLNA, and the corresponding DLNA media server / player, have been around since 2003 (and in fact, UPnP and the corresponding UPnP media server / player, the standards on which DLNA itself is based, have been around even longer than that), but they were made popular only in 2007, when Sony included a DMP implementation in its Playstation 3 (PS3) and Microsoft did the same with the Xbox 360. Those mass-market devices were by far more popular than any other DMP in the market back then (and they probably still are) but they could not have been successful without the TVersity Media Server, the leading DLNA media server at the time as well as today. Both Sony and Microsoft also added this functionality to the Playstation 4 (PS4) and the Xbox One due to high user demand.
The TVersity Media Server made its first debut back in May of 2005 and it featured support for a UPnP Media Server from its very first release, as well as support for real-time transcoding and for Internet content.
The combination of the TVersity DLNA Media Server with the PS3 and PS4 and the Xbox 360 and Xbox One is a match made in heaven. Both the Xbox 360 and PS3 were unable back then to play DivX files (and they are still unable to play MKV files), and TVersity was the first and only media server to amend this issue in an effortless manner thanks to its ability to transcode in real-time. Similarly both the Xbox One and the Sony PS4 have severe format limitations that TVersity eliminates. The end result is that pairing the Xbox 360, Xbox One, Sony PS3 or Sony PS4 with TVersity allows millions of people to watch their entire library of multimedia content on TV every day.
In recent years, a very long list of device models were added to the DLNA media player family, including smart TVs, blu-ray players, Stereo receivers and other popular devices like Roku.
Today it is estimated that over 3 billion DLNA devices were shipped worldwide. Curiously media servers are still, for the most part, relegated to PCs with some software like TVersity Media Server serving the content to the player.
