Digital Living Network Alliance (DLNA) (originally named Digital Home Working Group, DHWG) was founded by a group of PC and consumer electronics companies in June 2003 (with Intel in the lead role) to develop and promote a set of interoperability guidelines for sharingdigital media among multimedia devices under the auspice of a certification standard. DLNA certified devices include smartphones, tablets, PCs, TV sets and storage servers; in a typical use case, a user sends videos, pictures or music from their smartphone or storage server through their home WLAN to a TV set or tablet for display.
The group published its first set of guidelines in June 2004.[2] The guidelines incorporate several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, and widely used digital media formats and wired and wireless networking standards.[5]
DLNA works with cable, satellite, and telecom service providers to provide link protection on each end of the data transfer. The extra layer of digital rights management (DRM) security allows broadcast operators to enable consumers to share their content on multimedia devices without the risk of piracy.[6][7] In March 2014, DLNA publicly released the VidiPath Guidelines, originally called 'DLNA CVP-2 Guidelines.' VidiPath enables consumers to view subscription TV content on a wide variety of devices including televisions, tablets, phones, Blu-ray players, set top boxes (STBs), personal computers (PCs) and game consoles without any additional intermediate devices from the service provider.
PS3 Media Server is a DLNA compliant Upnp Media Server for the PS3, written in Java, with the purpose of streaming or transcoding any kind of media files, with minimum configuration. A media server is simply a specialized file server or computer system for storing media (digital videos/movies, audio/music, and images) which can be accessed over a network. In order to setup a media server, you need computer hardware (or perhaps a cloud server) as well as a software that enables.
As of September 2014,[8] over 25,000 different device models had obtained 'DLNA Certified' status, indicated by a logo on their packaging and confirming their interoperability with other devices.[9] It was estimated that by 2017 over 6 billion DLNA-certified devices, from digital cameras to game consoles and TVs, would be installed in users' homes.[10]
As of June 2015 the organization claimed membership of 'more than 200 companies'.[4] On January 5, 2017, DLNA announced on its web site that 'the organization has fulfilled its mission and will dissolve as a non-profit trade association.' Its certification program will be conducted by SpireSpark International of Portland, Oregon.
Jun 04, 2019 PLEX Media Server. The Plex media server is freemium software and offers some features on a subscription base only. Whereas the Plex player comes under both freemium and open source license GPL v2. Due to its vast range of device support the Plex continuously gaining its popularity as a media streamer. Although this Control Panel doesn’t mention the term “DLNA” at all, the media streaming feature in Windows is a DLNA-compliant media server. You can now customize the streaming settings. The default settings allow all devices on your local network to access the media files in your media libraries, and that’s fine if you’re on a local network with only devices you trust.
History[edit]
Intel established the DLNA along with Sony and Microsoft in June 2003 as the Digital Home Working Group, changing its 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[edit]
The DLNA Certified Device Classes are separated as follows:[11]
Home Network Devices[edit]
Mobile Handheld Devices[edit]
Home Infrastructure Devices[edit]
The specification uses DTCP-IP as 'link protection' for copyright-protected commercial content between one device to another.[1][12]
DLNA guideline versions[edit]
Member companies[edit]
As of November 2015, there are 13 promoter members and 171 contributor members. The promoter members are:[16]
Arris, AwoX, Broadcom, CableLabs, Comcast, Dolby Laboratories, Intel, LG Electronics, Panasonic, Samsung Electronics, Sony Electronics, Time Warner Cable, and Verizon.
Neither Google nor Apple are members. Apple's proprietary Digital Audio Access Protocol preceded DLNA's UPnP protocols.
The board of directors oversees the activity of the four following committees:
Products supporting DLNA[edit]DLNA-certified devices[edit]
There are over 25,000 DLNA-certified products on the market,[8] up from 9,000 in 2011.[17] This includes TVs, DVD and Blu-ray players, games consoles, digital media players, photo frames, cameras, NAS devices, PCs, mobile handsets, and more.[18] According to a study from Parks Associates,[10] nearly 3 billion products are on the market in 2014 reaching up to over 7 billion by 2018. 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.[19]
Manufacturers can seek certification testing from a DLNA Accredited Independent Certification Vendor such as the UNH InterOperability Laboratory,[20] Allion Labs, CESI Technology Co., Digital TV Labs,[21] XXCAL or Testronic.[22]

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.[24]
DLNA-certified software[edit]
In 2005,[31] 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.[32]
