Twonky Server is a media server software designed to facilitate the streaming of media content, including music, videos, and images, across different devices on a network. It achieves this by providing a DLNA (Digital Living Network Alliance) and UPnP (Universal Plug and Play) compliant server that can be accessed by any device supporting these standards. This capability allows users to enjoy their media collections on a variety of devices, such as smart TVs, gaming consoles, smartphones, and tablets, without the need for cables or manual file transfers.
One of the biggest points of confusion for users is the difference between a standalone license and the one that comes with your NAS. Twonky gone - QNAP NAS Community Forum
