Officially it's the acronym for Digital Living Network Alliance
But I like to call it Direct Local Network Access as it is more descriptive of what it actually is š
It's a way to access media files on your network that is file-system independent. Meaning it doesn't matter if its FAT NTFS Ext and whatnot. (Windows, linux, iOS/MAC OS, arm, x86, 32bit, 64bit.... and so on) and cross subdomains.
SMB on the other hand is much easier to use, but you must use compatible file-systems. And I think has to be on the same subdomain also.
oh, and if you wonder what it's actually used for with our apps. Its so you can access VR content stored on other devices at home. - It's also a lot easier to hide a DLNA than SMB if you don't want any one to know about it.
