Title:
SYSTEM AND METHOD FOR REDUCED COMMUNICATION LOAD THROUGH LOSSLESS DATA REDUCTION
Document Type and Number:
WIPO Patent Application WO/2021/206251
Kind Code:
A1
Abstract:
A method includes obtaining, from a memory of an electronic device connected to a head mounted display (HMD), a first reference frame, wherein the first reference frame comprises a first set of pixels associated with a first time. The method includes, rendering, at the electronic device, a source image as a new frame, wherein the new frame includes a second set of pixels associated with a display to be provided by the HMD at a second time, and generating, by the electronic device, a differential frame, wherein the differential frame is based on a difference operation between pixels of the new frame with pixels of the first reference frame to identify pixels unique to the new frame. Still further, the method includes sending the differential frame to the HMD, and storing the new frame in the memory of the electronic device as a second reference frame.
