Researchers at Austria’s Graz University of Technology (TU Graz) have developed a combined cloud computing/virtual reality (VR) streaming technology that will allow affordable, untethered VR headsets to display computer games in extremely high quality.

The Shading Atlas Streaming technique delivers compelling VR experiences with substantially fewer bits per second broadcast over the network by streaming geometrically encoded data rather than videos; the headset decodes the data and renders it into an image.

Said TU Graz’s Dieter Schmalstieg, "Our encoding allows correct images to be predicted for a small temporal window into the future. As a result, physical latency is compensated for, and the user does not perceive any delays."

The researchers utilize conventional MPEG video compression for encoding and transmitting data; because VR headsets already support MPEG decoding, Shading Atlas Streaming does not require the addition of any new hardware.
