DLNA allows for the transfer of media between devices on a local network, offering an alternative to internet-based streaming and supporting both online and offline content access.

⭐ Core Definition: DLNA

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. 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. Many routers and network attached storage (NAS) devices have built-in DLNA support, as well as software applications like Windows Media Player.

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. 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" before dissolving in 2017. By September 2014 over 25,000 device models had obtained "DLNA Certified" status, indicated by a logo on their packaging and confirming their interoperability with other devices.

👉 DLNA in the context of Streaming media

Streaming media is multimedia delivered through a network for playback using a media player. Media is transferred in a stream of packets from a server to a client and is rendered in real-time or near real-time; this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content. Streaming is more commonly used for video on demand, streaming television, and music streaming services over the Internet.

While streaming is most commonly associated with multimedia from a remote server over the Internet, it also includes offline multimedia between devices on a local area network. For example, using DLNA and a home server, or in a personal area network between two devices using Bluetooth (which uses radio waves rather than IP). Online streaming was initially popularized by RealNetworks and Microsoft in the 1990s and has since grown to become the globally most popular method for consuming music and videos, with numerous competing subscription services being offered since the 2010s. Audio streaming to wireless speakers, often using Bluetooth, is another use that has become prevalent during that decade. Live streaming is the real-time delivery of content during production, much as live television broadcasts content via television channels.
