ABSTRACT:
The invention relates to a method and device for the time-synchronised relaying of signals, whereby various signals from at least one signal source are relayed over various signal paths to at least one signal receiver, with time markers overlaid on the various signals. The delays occurring in the various signal paths are determined, a minimum total delay is calculated from the determined delays and information as to the minimal total delay is inserted in the various signals in the form of time-markers. A time-synchronous relaying of the signals is guaranteed in each signal path by means of an individual signal delay, the delay value of which corresponds to the difference between the minimal total delay and the delay caused by signal processing imposed on the signal in each signal path.
