The UPnP AV standard by definition is limited to certain types of devices and only supports a restricted set of functionality. Many devices or sources of media, such as TV receivers, CD or DVD players, cameras, or IPTV are not supported directly.

The NMM UPnP AV server overcomes these limitations. It enables access - and to some extent also control - to all devices and sources of media available in the network. It thereby combines the 'NMM network' with standard UPnP AV devices. In addition, the NMM UPnP AV server also offers the advanced feature of handover, also called follow-me: A media presentation started on one device at a certain location can be seamlessly handed over to a second device at a different location. For example, if the user moves from the living-room to the bedroom, a single press on the remote control hands over the media presentation to the current location. When using the NMM UPnP AV server all this is possible using existing and unmodified UPnP AV renderers, such as commodity set-top boxes.
