A video signal transmission system for reduced bandwidth transmission defines each picture frame to include at least two picture element series Aij, Bij, . . . A regularly selective transmitter selects the video picture element signals of a given series, in succession for all such series, in corresponding, successive picture frame periods, the selected signals being predictively coded for transmission. In the receiver, a frame memory stores the predictively coded signals for all picture element series of an entire picture frame, the content of the memory being renewed, or updated, in each successive frame period with the picture element signals of the received, corresponding series. The frame memory is read out completely during each frame period, and the predictively coded signals are decoded and combined to produce the output video signal for a complete picture frame. |
