Media Server User’s Guide

This section provides technical background information on the topics discussed in this chapter.

The media server feature lets anyone on your network play video, music, and photos from the NSA 
(without having to copy them to another computer). The NSA can function as a DLNA-compliant 
media server and/or an iTunes server. The NSA streams files to DLNA-compliant media clients or 
computers using iTunes. The Digital Living Network Alliance (DLNA) is a group of personal computer 
and electronics companies that works to make products compatible in a home network.

• Publish shares to let others play the contained media files. 
• The media server is a convenient way to share files you download using the broadcatching 

service (see 

).

• Hardware-based media players can also play the files. See 

 for the 

supported multimedia file formats.

Note: Anyone on your network can play the media files in the published shares. No user 

name and password or other form of security is used. The media server is enabled 

by default with the video, photo, and music shares published. 

After using iTunes on your computer to download songs from Apple’s iTunes Store, you can copy 
them to the NSA. Many of these songs have DRM (Digital Rights Management). At the time of 
writing, you can use your Apple account ID and password to authorize up to a total of five 
computers to play the files. To authorize a computer, open iTunes and click Store > Authorize 
Computer.
