As resolutions and refresh rates of displays increase, the required transmission bandwidth of the displayed image becomes a major limiting factor. For virtual reality (VR) and augmented reality (AR) headsets or head mounted displays (HMDs), this becomes an even bigger problem as the physical thickness of the cable is a concern as it hinders user mobility, and adding more wires to transmit higher resolution images is an unacceptable solution. In order to create an immersive environment for the user, VR and AR video streaming applications typically require high resolution and high frame-rates, which equates to high data-rates. In the case of VR and AR displays, it is wasteful to transmit the full uniform resolution image as is commonly done today.
