Nokia Play To for Windows Phone
by Volker Weber
With the “Play To” application for Nokia Lumia phones you can show pictures and videos wirelessly on other DLNA capable devices (TV’s, BlueRay players, Mediaplayer in Windows 7, etc) connected to their network.
That's a pretty cool solution which does the same thing as Apple Airplay, only for the rest of the world. I am using this on my N8 to play music on a Sonos ZonePlayer, which also happens to be a DNLA target.
Future releases of the application are planned to also include support for music.
That's available on Nokia Belle, but not yet on Windows Phone.
