  Virtual reality systems today cannot yet stream immersive, retina-quality
virtual reality video over a network. One of the greatest challenges to this
goal is the sheer data rates required to transmit retina-quality video frames
at high resolutions and frame rates. Recent work has leveraged the decay of
visual acuity in human perception in novel gaze-contingent video compression
techniques. In this paper, we show that reducing the motion-to-photon latency
of a system itself is a key method for improving the compression ratio of
gaze-contingent compression. Our key finding is that a client and streaming
server system with sub-15ms latency can achieve 5x better compression than
traditional techniques while also using simpler software algorithms than
previous work.
