DLNA (Digital Living Network Alliance) is a standard used by manufacturers of consumer electronics to allow entertainment devices within the home to share their content with each other across a home network.
As of August 2009 it is supported in more than 5,500 different devices and in 2008 over 200 million devices sold with it built in [2]

The DLNA specification categorizes devices into four categories:
- Digital media servers (DMS)
- Digital media players (DMP)
- Digital media controllers (DMC)
- Digital media renderers (DMR)
The specification also includes DRM, a scheme to ensure that the "content must be protected from unauthorized copying and use"[3].
Overview
DLNA intends to solve the problems inherent in using digital media between different consumer electronic devices. For example, a DLNA compliant TV will interoperate with a DLNA compliant PC to play music, photos or videos.
DLNA has been adopted by some of the world's biggest consumer electronics companies, including, but not limited to Hewlett-Packard, Intel, LG Electronics, Microsoft, Motorola, Nokia, Panasonic, Philips, Pioneer, Samsung, Sharp and Sony.
DLNA counts over 240 members most of them being contributor members and 24 being promoter members actively participating to DLNA's evolution. DLNA is run by a board of directors of 9 member companies : AwoX [4], Broadcom, Intel, Microsoft, Nokia, Panasonic, Philips, Samsung, Acer, and Sony.
The board of directors oversees the activity of the four following committees:
- Compliance & Test Committee, overseeing the certification program and its evolutions.
- Ecosystem Committee, planning the future development of DLNA guidelines.
- Marketing Committee, actively promoting DLNA worldwide.
- Technical Committee, writing the DLNA guidelines.
Versions
The first set of guidelines for DLNA was published in June 2004 with devices using it being released after that. v1.5 of the guidelines was published in March 2006 and expanded in October of the same year. This allowed more secure transmission of files and more support for home and mobile devices. The DLNA organization is attempting to expand the guidelines for other consumer devices such as mobile devices, printers. It's also looking to support MPEG-4 AVC, Bluetooth as a transport, and a better Quality of service.
PC Integration
Any PC with a network interface (eg Ethernet or WiFi) can become a DLNA device by installing DLNA software.[5] Some examples of DLNA compliant software include:
- ArcSoft TotalMedia 3.5 [1]. Appears to be just a DMS.
- CyberLink SoftDMA 2 [2]. Appears to be just a DMP.
- CyberLink Media Server 2 [3]. Appears to be just a DMS.
- Freevo [4] is open source and free software.
- LinuxMCE as a complete free solution has Fuppes integrated, but plans to switch to MediaTomb.[6]
- Moovida (formerly Elisa) [5] is open source and free software.
- MythTV [6] is an open source and free media server and client for Linux, Max OS X and Windows.
- PlayON from MediaMall [7]. Appears to be a DMS, also capable of serving streamed internet media such as Netflix, Hulu, YouTube, CNN, ESPN.
- TVMOBiLi - A free DLNA/UPnP Media Server for Windows, Mac OS X and Linux. [8]. Appears to be just a DMS.
- TVersity, a free UPnP MediaServer with strong device support and on-the-fly transcoding. [9]. Appears to be just a DMS [7].
- Windows Media Connect and therefore Windows Media Player 11 reportedly support DLNA, but there appears to be problems, for example, with PS3 consoles.[8]
- Windows Media Player 12 (bundled with Windows 7) supports all DLNA roles.
- XBMC a free and open source (GPL) software media player and entertainment hub for digital media available for Linux, Mac OS X, Microsoft Windows, as well as the original Xbox game console. XBMC reportedly supports DLNA
- Wild Media Server (UPnP, DLNA, HTTP), a trial media server for Windows, Wine (Linux), CrossOver Mac (MAC OS), individual device settings, transcoding, subtitles, restricted device access to folders, Internet-Radio, Internet-Television, Digital Video Broadcasting (DVB), etc.
Also see this comprehensive list of UPnP AV MediaServers that includes ones that are DLNA compliant. Note, however, that not all that are DLNA compliant are listed as such. Robert Green publishes a comparison chart of DLNA servers for Windows, Mac OS X and Linux.
