Plex Media Server

Plex Media Server is used to host the content and plugins that are then streamed to Plex big screen apps (including Plex Home Theater) and Plex mobile apps, either on the same machine, the same local area network, or over the Internet. In addition to the platforms supported by the front end, the server is available for FreeBSD, Linux and nine different NAS devices. Plex Media Server can be configured to index content in any directory on the machine it is run on, as well as to automatically acquire content from such sources as Aperture, iPhoto, and iTunes. Content may be transcoded by the server before it is streamed, in order to reduce bandwidth requirements or for compatibility with the device being streamed to.

Plex Media Server allows extensibility through the addition of plug-ins. Many such plug-ins are available through the built-in Plex Online digital distribution service. This service can be used directly within Plex Home Theater or Plex Media Center's GUI.

Plex uses the metadata from several free open-source online libraries to automatically find all artwork, media descriptions, and theme music for the entire library.
