ABSTRACT:
The invention involves a method of transmitting a control signal that is synchronized in time with a radio program signal. The control signal may be used, for example, in a receiver to restore dynamic range reduction that occurred at the transmitter. The method includes the steps of forming a first supplemented signal by inserting the control signal and a first time-reference signal into a data stream of a radio data signal such as an RDS signal. A second supplemented signal is formed by adding a second time-reference signal to the radio program signal. The first and second time-reference signals are correlated in time. The first and second supplemented signals are transmitted.
