Abstract
Information signals (Y1, C1; Y2, C2: Y3, C3) relating to the same video image but each defining the image with a different accuracy are transmitted asynchronously and on a time division basis as packet sets (Y1, C1; Y21, C21; Y32, C32). In a receiving station (SS2) the information signals are derived from the received packet sets and by means of selection circuit (SEC1/3) two or more of these signals are supplied to a combination device (VTE) and are combined therein to form an image.
