Digital Living Network Alliance (DLNA) (originally named Digital Home Working Group [DHWG]) was founded by a group of consumer electronics companies in June 2003 (with Sony in the lead role) to develop and promote a set of interoperability guidelines for sharing digital media among multimedia devices under the auspice of a certification standard. 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 feel good about enabling consumers to share their content on multimedia devices without the risk of piracy.[4][5] As of June 2015 the organization claims membership of "more than 200 companies".[3]

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.[6]

In March 2014, DLNA publicly released the VidiPath Guidelines, originally called "DLNA CVP-2 Guidelines." VidiPath is a set of guidelines developed by DLNA that 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.

As of October 2015,[7] over 25,000 different device models have obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices.[8] 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.[9]

History

Sony established the DLNA 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

The DLNA Certified Device Classes are separated as follows:[10]

Home Network Devices

Mobile Handheld Devices

Home Infrastructure Devices

The specification uses DTCP-IP as "link protection" for copyright-protected commercial content between one device to another.[1][11]

DLNA guideline versions

Member companies

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.

Apple is not a member but uses its own proprietary Digital Audio Access Protocol instead of DLNA's UPnP protocols.

The board of directors oversees the activity of the four following committees:

Products supporting DLNA

DLNA-certified devices

There are over nine thousand products on the market that are DLNA Certified.[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,[9] 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]

DLNA technology components

As the past president of DLNA pointed out to the Register in March 2009:[23]

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

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]

DLNA-certified products

Some examples:[33]

  • AwoX mediaCTRL[34] is a commercial server. It is based on AwoX DLNA Technology component software development kits.[35]
  • CyberLink SoftDMA 2.[36] Appears to be just a DMP.
  • ARRIS Whole Home Media Gateway is a DLNA Certified DMS.[37][38]
  • ARRIS Whole Home Media Player is a DLNA Certified DMP.[37][38]
  • Most Smartphones share multimedia including music, pictures or videos.
  • Microsoft Xbox 360[39] is a DLNA Certified DMP.
  • Sony PlayStation 3[40] is a DLNA Certified DMP.
