In transmission of bit plane coded (23) digitalized moving pictures, which are subject to a motion compensation (19) and an object based segmentation the bit planes are transmitted in order of decreasing significance. An incremental motion estimation (15, 17) and segmentation (11, 13) is performed in the transmitter (1) and the receiver (5) after each transmitted bit plane of a frame of the moving picture. As a result hereof the information, in particular the segmentation information, which must be transmitted is, in particular in the case of a low transmission rate, significantly reduced, due to the heavy reduction of motion parameters which must be transmitted. This method is, in particular, well suited for employment in low rate transmission systems, such as the public telephone network. |
