Abstract
A method and device for distorted compression of images displayed over a head mounted display (HMD) are provided. The method includes receiving, at a sink device, an image from a source device over a transport medium; determining, based on the optical means of the HMD, a circumscribed circle of the received image; determining a compression ratio based on at least radial attributes of the received image; and compressing, using a compression process, pixels inside the circumscribed circle of the received image, wherein the compression is based on the determined compression ratio.
