Abstract:
Systems, apparatuses, and methods for using a multi-stream foveal display transport layer are disclosed. A virtual reality (VR) system includes a transmitter sending a plurality of streams over a display transport layer to a receiver coupled to a display. Each stream corresponds to a different image to be blended together by the receiver. The images include at least a foveal region image corresponding to a gaze direction of the eye and a background image which is a lower-resolution image with a wider field of view than the foveal region image. The phase timing of the foveal region stream being sent over the transport layer is adjusted with respect to the background stream to correspond to the location of the foveal region within the overall image. This helps to reduce the amount of buffering needed at the receiver for blending the images together to create a final image to be driven to the display.
