What Media Server Software Does
You use media server software to set up a host computer as a streaming media server. The server "serves" your stored media to other devices connected to your home network. This might include smart TVs, networked A/V receivers and Blu-ray players, Xbox and PlayStation game consoles, media player boxes, even smartphones and tablets. Just about any DLNA-compatible device can access digital media from your media server and its library.
Most media server software handles just about any type of digital media you might have[md]videos (movies, TV shows, home movies), music, and digital photographs. It doesn't matter where this media came from, either; a media server will serve movies and music purchased from iTunes, downloaded from file sharing sites, or ripped from CD or DVD. As long as it's a media file stored in digital format, the media server can handle it.
Some media server software even lets you stream your local media to devices outside your home, over the Internet. This way you can access your home media library when you're traveling or away from home.
Most media server software is relatively inexpensive; some apps are even free. The app installs on your PC, discovers and accesses all your digital media files, and then connects to the other devices on your home network. In most instances it's a surprisingly simple experience, although some technical know-how is helpful.
Know that you don't have to set up a dedicated PC as you media server. You can install media server software on any computer and still use that PC for your normal everyday computing tasks. The media serving goes on in the background while you're emailing and tweeting and doing whatever else you do on your computer.
The key thing is to install the media server software on the same computer on which you have most (if not all) of your digital media files stored[md]even if they're stored on an external hard disk connected to that PC. You also need your media server PC to be always on, so that your other networked devices have access 24/7.
Once your media server software is up and running, you can connect to the server from just about any connected device. Go into the setup screen and find the server; the rest should happen automatically.
