Abstract
A method of operating a VR or AR head mounted display (HMD) system includes obtaining a video performance parameter for a video signal, selecting a clock frequency for video data transfer within the HMD system based on the video performance parameter, detecting one or more available frequency bands for a wireless data connection between a host device and the HMD system, and selecting a frequency band from the one or more available frequency bands for the wireless data connection, based on a predetermined connection suitability parameter for the one or more available frequency bands and based on the selected clock frequency for video data transfer within the HMD system. The method further includes establishing a wireless connection between the host device and the HMD system over the selected frequency band.
