Digital Living Network Alliance (DLNA) is a set of interoperability standards for sharing home digital media among multimedia devices. It allows users to share or stream stored media files to various certified devices on the same network like PCs, smartphones, TV sets, game consoles, stereo systems, and NASs. [1] DLNA incorporates several existing public standards, including Universal Plug and Play (UPnP) for media management and device discovery and control, wired and wireless networking standards, and widely used digital media formats. [2] [3]
DLNA was created by Sony and Intel and the consortium soon included various PC and consumer electronics companies, publishing its first set of guidelines in June 2004. [4] The Digital Living Network Alliance developed and promoted it under the auspices of a certification standard, with a claimed membership of "more than 200 companies" [5] before dissolving in 2017. By September 2014 [6] over 25,000 device models had obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices. [7] In many cases DLNA protocols are in use by services or software without openly stating the name: examples include Nokia's Home Network functionality, [8] Samsung's All Share, [9] the Play To functionality in Windows 8.1, [10] and in applications such as VLC media player or Roku Media Player.
The DLNA Certified Device Classes are separated as follows: [11]
The specification uses DTCP-IP as "link protection" for copyright-protected commercial content between one device to another. [12] [13]
Some of the earlier devices with DLNA included the PlayStation 3, the Nokia N95 [8] and the Pioneer BDP-HD1 Blu-ray player. [17] By 2014 over 25,000 DLNA-certified products were available, [6] up from 9,000 in 2011. [18] This includes TVs, DVD and Blu-ray players, games consoles, digital media players, photo frames, cameras, NAS devices, PCs, mobile handsets, and more. [19] According to a 2013 study from Parks Associates, [20] nearly 3 billion products were expected to be on the market in 2014, increasing to over 7 billion by 2018. DLNA certification of devices can be determined by a DLNA logo on the device, or by verifying certification through the DLNA Product Search. [21]
In 2005, [22] 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. [23]

Intel established the Digital Network Living Alliance along with Sony and Microsoft in June 2003 as the Digital Home Working Group (DHWG), changing its name 12 months later, when the first set of guidelines for DLNA was published. [12] Its board members as of 2007 were: HP, Intel, Matsushita, Microsoft, Nokia, Phillips, Samsung, and Sony. [25]
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. [12]
DLNA worked 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 communicate digital media to certain devices (e.g. to those of their customers) in such a manner that further, unauthorized, communication of the media is difficult. [26] [27]
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.
In November 2015 there were 13 promoter members and 171 contributor members. The promoter members were: [28]
Arris, AwoX, Broadcom, CableLabs, Comcast, Dolby Laboratories, Intel, LG Electronics, Panasonic, Samsung Electronics, Sony Electronics, Time Warner Cable, and Verizon.
The board of directors oversaw the activity of the four following committees:
On January 5, 2017, the DLNA organization announced, "The organization has fulfilled its mission and will dissolve as a non-profit trade association." Its certification program continues to be conducted by SpireSpark International of Portland, Oregon. [29] [30]
As the past president of DLNA pointed out to the Register in March 2009: [31]
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 following sections of key technology components: [32]
Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and establish functional network services. UPnP is intended primarily for residential networks without enterprise-class devices.
Streamium was a line of IP-enabled entertainment products by Dutch electronics multi-national Philips Consumer Electronics. Streamium products use Wi-Fi to stream multimedia content from desktop computers or Internet-based services to home entertainment devices. A Streamium device plugged into the local home network will be able to see multimedia files that are in different UPnP-enabled computers, PDAs and other networking devices that run UPnP AV MediaServer software.
DMR is an initialism that may refer to:
The High-Definition Audio-Video Network Alliance (HANA) was a cross-industry collaboration of members addressing the end-to-end needs of connected, HD, home entertainment products and services. Leading companies formed the organization from the four industries most affected by the HD revolution: content providers, consumer electronics, service providers, and information technology. HANA created design guidelines for secure high-definition audio-video networks that would speed the creation of new, high-quality, easy-to-use HD products. HANA membership was open to all companies involved in the digital entertainment industry. HANA was dissolved in September 2009, and the 1394 Trade Association assumed control of all HANA-generated intellectual property.
WirelessHD, also known as UltraGig, is a proprietary standard owned by Silicon Image for wireless transmission of high-definition video content for consumer electronics products. The consortium currently has over 40 adopters; key members behind the specification include Broadcom, Intel, LG, Panasonic, NEC, Samsung, SiBEAM, Sony, Philips and Toshiba. The founders intend the technology to be used for Consumer Electronic devices, PCs, and portable devices.
A digital media player is a type of consumer electronics device designed for the storage, playback, or viewing of digital media content. They are typically designed to be integrated into a home cinema configuration, and attached to a television or AV receiver or both.
A home server is a computing server located in a private computing residence providing services to other devices inside or outside the household through a home network or the Internet. Such services may include file and printer serving, media center serving, home automation control, web serving, web caching, file sharing and synchronization, video surveillance and digital video recorder, calendar and contact sharing and synchronization, account authentication, and backup services.
Monsoon Multimedia was a company that manufactured, developed and sold video streaming and place-shifting devices that allowed consumers to view and control live television on PCs connected to a local (home) network or remotely from a broadband-connected PC or mobile phone. It was one of 5 major transformations initiated by Prabhat Jain, a Silicon Valley entrepreneur with 5 undergraduate and post graduate engineering degrees from Cal Berkeley and Univ of Vienna, Austria. On the even of Cisco acquiring Monsoon in 2017, EchoStar, the new parent of Sling sued Monsoon for patent infringement, having obtained confidential information about the date of the acquisition by Cisco from a Monsoon employee under murky circumstances. Monsoon settled the lawsuit by agreeing not to sell its products in the USA simply because it did not have the legal funds to fight mighty Echostar's legal maneuvers. EchoStar thus successfully removed its only competitor from the market place. This meant Monsoon's death knell.
PlayOn is a streaming media brand and software suite that enables users to view and record videos from numerous online content providers. The suite consists of two main products: PlayOn Cloud and PlayOn Desktop. PlayOn Cloud is an online service for recording digital video streams, accessible via native iOS or Android mobile device applications. PlayOn Desktop is Windows-based software that acts as a streaming dashboard and hub on the PC. The available streaming websites are organized as channels in both products. Users browse through or search the video content found in those channels in order to record the videos for later viewing. PlayOn Desktop allows watching the videos real-time on the PC, or casting the videos to a TV via a streaming device or gaming console.
TwonkyMedia server (TMS) is DLNA-compliant UPnP AV server software originally offered by TwonkyVision GmbH. TMS runs on Linux, macOS, Microsoft Windows, iOS, Android and QNX operating systems. TwonkyMedia server can be used to share and stream media to most UPnP AV or DLNA-compliant clients, in addition to non-UPnP devices through the HTML, RSS, and JSON supported front ends. After the PacketVideo acquisition of Berlin-based TwonkyVision GmbH by 17 October 2006, Twonky was renamed PVConnect in November 2007, but the name was changed back to TwonkyMedia server by 7 January 2010. Corporate parent NTT DOCOMO sold PacketVideo NorthAmerica and Europe to Lynx Technology on 10 May 2015 and PacketVideo Japan exactly one year later on 10 May 2016 transferring the Twonky product line to Lynx, renaming TwonkyMedia Server to Twonky Server.
The RVU Alliance (RVUA) is a standards body created to manage the RVU protocol standard as used by manufacturers of consumer electronics to allow entertainment devices within the home to share their content with each other across a home network.
The RVU protocol is an Application Layer protocol, that combines the pre-existing Digital Living Network Alliance (DLNA) standards and a new Remote User Interface (RUI) protocol, which works similar to Remote Desktop Protocol (RDP). The RVU RUI protocol is intended to allow an RVU-enabled client, such as a TV, to receive a pixel-accurate display of the user interface available on an RVU server.
Skifta was a media shifting service developed by Qualcomm Atheros. It enabled Android and Apple (IOS) smartphone and tablet users to access their music, pictures, and videos from their phone, from cloud media services or remotely from another location via a smart mobile device. The user could then stream media to connected consumer electronics anywhere that supports DLNA and UPnP standards over WiFi or 3G networks.
SAT>IP specifies an IP-based client–server communication protocol for a TV gateway in which SAT>IP servers, connected to one or more DVB broadcast sources, send the program selected and requested by an SAT>IP client over an IP-based local area network in either unicast for the one requesting client or multicast in one datastream for several SAT>IP clients.
Avnu Alliance is a consortium of member companies working together to create an interoperable ecosystem of low-latency, time-synchronized, highly reliable networking devices using the IEEE open standard, Time-Sensitive Networking (TSN) and its Pro AV networking protocol, Milan. Avnu Alliance creates comprehensive certification programs to ensure interoperability of network devices. In the Professional Audio Video (AV) industry, Alliance member companies worked together to develop Milan: a standards-based, user-driven deterministic network protocol for professional media, that through certification, assures devices will work together at new levels of convenience, reliability, and functionality. Milan™ is a standards-based deterministic network protocol for real time media. Avnu Members may use the Avnu-certified or Milan-certified logo on devices that pass the conformance tests from Avnu. Not every device based on AVB or TSN is submitted for certification to the Avnu Alliance. The lack of the Avnu logo does not necessarily imply a device is incompatible with other Avnu-certified devices. The Alliance, in conjunction with other complimentary standards bodies and alliances, provides a united network foundation for use in professional AV, automotive, industrial control and consumer segments.
Serviio is a freeware media server designed to let users stream music, video or image files to DLNA compliant televisions, Blu-ray players, game consoles and Android or Windows Mobile devices on a home network.
Universal Media Server is a DLNA-compliant UPnP media server. It originated as a fork of PS3 Media Server. It allows streaming of media files to a wide range of devices including video game consoles, smart TVs, smartphones, and Blu-ray players. It streams and transcodes multimedia files over a network connection to the rendering device, ensuring that a supported rendering device will receive the content in a format supported by the device. Transcoding is accomplished through packages from AviSynth, FFMpeg, MEncoder, and VLC.
VidiPath is a set of guidelines developed by the Digital Living Network Alliance (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. Consumer Electronics (CE) products that are certified to the VidiPath Guidelines can directly support the full range of subscriber HD programs, movies, DVR content, channel guides, and other premium features, all with a consistent user interface (UI) from their service provider.
BubbleUPnP is a DLNA-compliant UPnP media controller, server and renderer, designed to allow streaming of audio or video from and to an Android device with various external devices and software. Alongside the Android client, it also has a server middleware application that can be installed on Windows, macOS and Linux computers or network storage devices, providing remote access through a web interface. BubbleUPnP also utilises ffmpeg and ffprobe for transcoding.
