Abstract
Described herein are, among other things, techniques, devices, and systems for streaming pixel data from a host computer to a wireless display device with low latency. In some embodiments, a user mode driver is executed in user mode of the host computer to configure a wireless network interface controller of the host computer to operate in a low latency manner. The display device may use a Forward Error Correction (FEC) algorithm to reconstruct a frame from the data packets it receives from the host computer. Also disclosed are techniques for scrambling the transmission of a series of data packets using different antenna configurations, as well as setting a modulation and coding scheme (MCS) rate based at least in part on the amount of pixel data to be transmitted to the display device. The display device may comprise a head-mounted display (HMD) that renders virtual reality (VR) game imagery.
