Despite the high video data rates demanded by VR applications, DisplayLink's compression system can maintain the resolution, quality, and frame rate of the VR video stream but with no discernible increase in latency compared to a direct connected display. However, most standard compression systems such as MPEG create a delay in the video stream, and if the end-to-end latency through the system (which includes sensing head movement, generating all the pixels in the next frame in the VR scene, and streaming the video) moves beyond about 20ms, the user will start to feel motion sickness.ĭisplayLink XR matches our unique approach to video compression with deep technical partnerships with leading wireless networking companies.
This is a big challenge since the video data rate on first generation VR HMDs is already four times greater than that of a high definition TV and too much for any wireless link without compression. DisplayLink XR has been developed specifically to deliver a wireless connection between the VR Head Mounted Display (HMD) and gaming PC or console, without compromising on video quality, latency, or frame rate compared to a wired solution.
