DLNA (Digital Living Network Alliance) is a set of guidelines for devices to share audio, video, and pictures over a home network. It is designed to enable multimedia content sharing between devices such as computers, smartphones, gaming consoles, and televisions. DLNA-certified devices can discover and communicate with each other and stream content without the need for additional software or apps.
DLNA has been around since 2003, and many manufacturers use it to enable media sharing between devices; some apps and platforms also use it to share media across devices. However, as of 2023, DLNA is not as popular as it used to be, is not as widely supported as other wireless streaming protocols, such as Chromecast and Airplay, and it's not as easy to use.
As of writing this glossary term, the Digital Living Networking Alliance (“DLNA”) has dissolved and is no longer operating. The DLNA alliances assets, such as its website, certification, testing services, and tools related to compliance with the DLNA Guidelines, are now being provided by SpireSpark International, Inc. with permission from DLNA.
