DLNA: Difference between revisions
Added PLEX to the short list of DLNA servers since I just read a discussion forum asking this question. Frankly, I think this list should be removed since there is a separate article for this and these read more like advertisements. |

The Digital Living Network Alliance (DLNA) is a non-profit collaborative trade organization established by Sony in June 2003, that is responsible for defining interoperability guidelines to enable sharing of digital media between multimedia devices.[3] These guidelines are built upon existing public standards, but the guidelines themselves are private (available for a fee). These guidelines specify a set of restricted ways of using the standards to achieve interoperability and include almost all free audio formats and the most common (free or otherwise) video formats, meaning that DLNA servers generally have to support transcoding in order to produce a useful service.[4]
DLNA uses Universal Plug and Play (UPnP) for media management, discovery and control.[5] UPnP defines the type of device that DLNA supports ("server", "renderer", "controller") and the mechanisms for accessing media over a network. The DLNA guidelines then apply a layer of restrictions over the types of media file format, encodings and resolutions that a device must support.
As of February 2013,[6] over 18,000 different device models have obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices.[7] It is estimated that more than 440 million DLNA-certified devices, from digital cameras to game consoles and TVs, have been installed in users' homes.[8]
History
Sony established the DLNA in June 2003 as the Digital Home Working Group, changing to its current name 12 months later, when the first set of guidelines for DLNA was published.[1] Home Networked Device Interoperability Guidelines v1.5 was published in March 2006 and expanded in October of the same year; the changes included the addition of two new product categories — printers, and mobile devices — as well as an "increase of DLNA Device Classes from two to twelve" and an increase in supported user scenarios related to the new product categories.[1]
Specification
The DLNA Certified Device Classes are separated as follows:[9]
Home Network Devices
- Digital Media Server (DMS): store content and make it available to networked digital media players (DMP) and digital media renderers (DMR). Examples include PCs and network-attached storage (NAS) devices.
- Digital Media Player (DMP): find content on digital media servers (DMS) and provide playback and rendering capabilities. Examples include TVs, stereos and home theaters, wireless monitors and game consoles.
- Digital Media Renderer (DMR): play content as instructed by a digital media controller (DMC), which will find content from a digital media server (DMS). Examples include TVs, audio/video receivers, video displays and remote speakers for music. It is possible for a single device (e.g. TV, A/V receiver, etc.) to function both as a DMR (receives "pushed" content from DMS) and DMP ("pulls" content from DMS)
- Digital Media Controller (DMC): find content on digital media servers (DMS) and instruct digital media renderers (DMR) to play the content. Content doesn't stream from or through the DMC. Examples include Internet tablets, Wi-Fi enabled digital cameras and smartphones.
- Digital Media Printer (DMPr): provide printing services to the DLNA home network. Generally, digital media players (DMP) and digital media controllers (DMC) with print capability can print to DMPr. Examples include networked photo printers and networked all-in-one printers
Mobile Handheld Devices
- Mobile Digital Media Server (M-DMS): store content and make it available to wired/wireless networked mobile digital media players (M-DMP), digital media renderers (DMR) and digital media printers (DMPr). Examples include mobile phones and portable music players.
- Mobile Digital Media Player (M-DMP): find and play content on a digital media server (DMS) or mobile digital media server (M-DMS). Examples include mobile phones and mobile media tablets designed for viewing multimedia content.
- Mobile Digital Media Uploader (M-DMU): send (upload) content to a digital media server (DMS) or mobile digital media server (M-DMS). Examples include digital cameras and mobile phones.
- Mobile Digital Media Downloader (M-DMD): find and store (download) content from a digital media server (DMS) or mobile digital media server (M-DMS). Examples include portable music players and mobile phones.
- Mobile Digital Media Controller (M-DMC): find content on a digital media server (DMS) or mobile digital media server (M-DMS) and send it to digital media renderers (DMR). Examples include personal digital assistants (PDAs) and mobile phones.
Home Infrastructure Devices
- Mobile Network Connectivity Function (M-NCF): provide a bridge between mobile handheld device network connectivity and home network connectivity.
- Media Interoperability Unit (MIU): provide content transformation between required media formats for home network and mobile handheld devices.
The specification uses Digital Transmission Content Protection|DTCP-IP as "link protection" for copyright-protected commercial content between one device to another.[1][10]
Member companies
As of June 2011, there are 26 promoter members and 199 contributor members. The promoter members are:[11]
ACCESS, AT&T Labs, Awox,[12] Broadcom, CableLabs, Cisco Systems, Comcast, DIRECTV, Dolby Laboratories, DTS, Ericsson, Google, Hewlett-Packard, HTC, Huawei, Intel, LG Electronics, Microsoft, Nokia, Panasonic, Qualcomm, Samsung Electronics, Sony Electronics, Technicolor, and Verizon.
Apple is not a member. Apple uses its own proprietary Digital Audio Access Protocol instead of DLNA's UPnP protocols.
DLNA is run by a board of directors consisting of 9 members. There are 8 permanent representatives from the following companies: Broadcom, Intel, Microsoft, Nokia, Samsung Electronics, Sony Electronics, Technicolor and one elected by the promoter members, AwoX.[12][13]
The board of directors oversees the activity of the four following committees:
- Ecosystem Committee, planning the future development of DLNA guidelines
- Compliance & Test Committee, overseeing the certification program and its evolutions
- Marketing Committee, actively promoting DLNA worldwide
- Technical Committee, writing the DLNA guidelines
Products supporting DLNA
DLNA-certified devices
There are over nine thousand products on the market that are DLNA Certified.[14] This includes TVs, DVD and Blu-ray players, games consoles, digital media players, photo frames, cameras, NAS devices, PCs, mobile handsets, and more.[15] “According to a study from ABI Research, nearly 200 million such products shipped in 2008; that number will rise to more than 300 million in 2012, and the growth curve accelerates even faster in the years that follow.”[16] Consumers can see if their product is certified by looking for a DLNA logo on the device or by verifying certification through the DLNA Product Search.[17]
Manufacturers can seek certification testing from a DLNA Accredited Independent Certification Vendor such as the UNH InterOperabiliy Laboratory,[18]Digital TV Labs,[19] or Testronic.[20]
DLNA technology components
As the past president of DLNA pointed out to the Register in March 2009:[21]
The vendors of software are allowed to claim that their software is a DLNA Technology Component if the software has gone through certification testing on a device and the device has been granted DLNA Certification. DLNA Technology Components are not marketed to the consumer but only to industry.
DLNA Interoperability Guidelines allow manufacturers to participate in the growing marketplace of networked devices and are separated into the below sections of key technology components.[22]
- Network and Connectivity[23]
- Device and Service Discovery and Control[24]
- Media Format and Transport Model[25]
- Media Management, Distribution and Control[26]
- Digital Rights Management and Content Protection[27]
- Manageability[28]
DLNA-certified software
In 2005,[29] DLNA began a Software Certification program in order to make it easier for consumers to share their digital media across a broader range of products. DLNA is certifying software that is sold directly to consumers through retailers, websites and mobile application stores. With DLNA Certified software, consumers can upgrade products from within their home networks that may not be DLNA Certified and bring them into their personal DLNA ecosystems. This helps in bringing content such as videos, photos and music stored on DLNA Certified devices to a larger selection of consumer electronics, mobile and PC products.[30]
