摘要

For individual tuning of the dynamics of a radio programme signal (variable dynamics), a control parameter is derived from the associated radio programme signal and emitted together with the programme signal. At the receiver, the control signal is used to select reproduction dynamics differing from the transmitted programme-signal dynamics. For transmission purposes, the control parameter is inserted as a digital auxiliary signal in a data stream which is transmitted asynchronously to the programme signal in a programme-signal-free region of the transmission band. The digital auxiliary signal is inserted at intervals as a data packet with varying advance with respect to the programme-signal section concerned. The variable time differences between the points in time at which the data packets are inserted and the occurence of the programme-signal sections are transmitted as separated time information in the data packets and used at the receiver to synchronize the advanced control signal with the programme signal.
