Abstract

Video encoding is provided using periodic intra refresh, which can adapt padding of an intra encoding region between image frames based on a current level motion in the image frame. Upon a current level of motion not exceeding a first threshold, an intra encoding region of the image frame according to a predefined periodic intra refresh pattern is intra encoded. Upon the current level of motion exceeding the first threshold, the intra encoding region of the image frame is expanded to overlap to a determined extent with a previously encoded intra encoding region among the plurality of image frames, and the expanded intra encoding region of the image frame is intra encoded. Regions of the image different from the intra encoding regions and the expanded intra encoded region, respectively are inter frame encoded.
