The picture receiving apparatus displays a portion of the transmitted picture which corresponds to a viewpoint. When the viewpoint is moved, information of the movement is transmitted from the picture receiving apparatus to the picture transmitting apparatus, and a picture corresponding to the new viewpoint is transmitted from the picture transmitting apparatus to the picture receiving apparatus. The picture receiving apparatus displays a portion of the received picture which corresponds to the viewpoint.
