ABSTRACT:
Motion in an image signal to be transmitted is detected to produce motion information. An encoded image signal comprising the image signal and the motion information is transmitted to a transmitting path. The encoded image signal is received from the transmitting path, and code errors are concealed according to an operating characteristic determined on the basis of the motion information.
