The UPnP AV Media Server
Introduction
Your MediaAccess Gateway has a built-in DLNA-certified UPnP AV media server. This section describes how to use and 
configure this media server.
UPnP AV
UPnP AV (AV stands for Audio and Video) is a protocol especially designed to share 
media
files on your 
local network
.
DLNA-certified
The Digital Living Network Alliance (DLNA) is an organisation that imposes requirements to ensure the interoperatability 
of your media devices and standardize the communication between them.
Buying a DLNA-certified device like the MediaAccess Gateway guarantees you that it will seamlessly integrate with your 
other DLNA-certified devices.
To allow you to access your media in a quick and easy way, the MediaAccess Gateway scans your storage device for meta 
data information (for example, title, artist, album) and stores it in a database. When you are looking for a file, the 
MediaAccess Gateway can simply query the database instead of having to go through all the files.
UPnP AV network components
A UPnP AV network consists of the following components:
The 
UPnP AV server
is directly connected to your media files and makes them available on the network. In your network 
the MediaAccess Gateway will fulfil this role.
The 
UPnP AV client 
is a software application or hardware device that allows you to play or view the media files provided 
by your UPnP AV media server.
This database will only be created if the following conditions are met:
Your disk or partition must have at least 250MB of free space
Your disk or partition must not be read-only.
