In this system, the video signal with a nominal bit rate of 135 Mbit/s, associated stuffing signals, synchronising signals and additional narrow-band signals are transmitted, a pulse frame comprising 2,176 time slots of 8 bits in each case, the pulse frame being divided into four equal subframes (TR1 to TR4) and each subframe having at equal intervals from one another several narrow-band channels (SK1 to SK8) comprising a total of 16 time slots (ZS), which are provided for transmitting synchronising signals and narrow-band signals. <IMAGE> |
