The DNLA supported devices including PS3 and Xbox are the receivers from the Playto on the Surface or Lumia phones. I use the Playto on my L1020 to cast media to the DNLA TV quite often. The video demonstrated that Surface 2 is used to cast media apps to a Xbox connected TV. The Xbox is a DNLA receiver which then displays the video or audio to the connected TV. If your TV supports DNLA, then you don't need Xbox (or PS3).
