Abstract: A system and method for providing motion compensation in decoding of a panoramic video. The panoramic video comprises a sequence encoded of image frames. Using inter frame prediction an image frame of a video is expressed in terms of at least one of neighboring image frames. In panoramic video image frames are mapped on a spherical viewing area. In the method the motion caused by camera movements is compensated by computing a difference between a reference frame and a current frame. The computed difference is then used when reconstructing the current frame, which may be placed to an image buffer and used as a reference frame for other frames.
