Patent ID: 8605848

Claim:
An arrangement comprising: a master station; individual high frequency transmitters of a common wave network operating according to an ATSC standard and transmitting respectively identical data at an identical frequency; wherein the master station generates a digital data stream and supplies the digital data stream to the individual transmitters as a periodic succession of data frames, a setpoint transmission time is calculated in the transmitters from a synchronizing time stamp inserted into the data frames within the master station and from a time reference used both in the master station and also in the transmitters, and the transmission of the data frames at an output of the transmitter is determined by a system clock generated by a system clock generator in the transmitters, a time comparator for comparing the setpoint transmission time in each transmitter with an actual transmission time determined by the system clock of the data frames at the output of the transmitter and, a regulating circuit for regulating, responsive to the comparison, a clock frequency of the system clock generator in such a manner that the actual transmission time determined by the system clock corresponds with the calculated setpoint transmission time; wherein, if the time comparator determines that the actual transmission time is later than the setpoint transmission time, the system clock is increased via the regulating circuit, thereby transmitting an output signal earlier and, if the time comparator determines that the actual transmission time is earlier than the setpoint transmission time, the system clock is decreased via the regulating circuit, thereby transmitting the output signal later.
