Disclosed is a system and method to provide continuity of service in a radio broadcasting system comprising at least one modem using the COFDM technique, comprising the transmission of N time-frequency cells modulated independently of one another. The method comprises at least the following steps: at transmission: a) sending a number N1 of cells conveying signals needed for the transmission of a digitized audio signal S1, b) sending a number N2 of modulated cells to transmit an analog signal S2 of analog audio samples, reception; c) when the signals of the N1 cells cannot be decoded, replacing the digitized audio signal S1 by the analog signal S2 conveyed by the cells N2.
