Abstract
Systems, methods and apparatuses of processing data of a VR system are disclosed that comprise receiving tracking information which includes at least one of user position information and eye gaze point information. One or more processors may be used to predict, based on the user tracking information, a user viewpoint of a next frame of a sequence of frames of video data to be displayed. Using the prediction, a portion of the next frame of video data to be displayed is rendered at an estimated location in the next frame. A corresponding matching portion in a previously encoded frame is determined based on the estimated location of the portion in the next frame and the portion of the next frame of video data is encoded.
