1. A system comprising at least one server that is communicably coupled to at least one display apparatus, wherein the at least one server is configured to:
detect a start of a smooth pursuit movement (T1) based on eye movement information received from the at least one display apparatus;
detect an object or image region in motion in a field of view displayed by the at least one display apparatus;
control remote rendering of an extended reality (XR) video stream at the at least one display apparatus by dynamically adjusting video compression and foveation parameters of the XR video stream during the smooth pursuit movement (T2) to prioritize visual clarity of the detected object or image region in motion over other elements in the displayed field of view;
detect an end of the smooth pursuit movement (T3); and
revert the video compression and foveation parameters to pre-set default settings after the end of the smooth pursuit movement (T3).
