  • Patent number: 5404566
    Abstract: A process for generating an entertainment audio signal interrupted by advertising audio signals in which pilot signals associated with the advertising audio signals cause switching between the entertainment audio signals and the advertising audio signals makes it possible to broadcast different radio programs of the desired acoustic quality in a shop by means of a carrier frequency. To this end, a high-frequency control signal is generated from advertising audio signals and pilot signals which precede or follow the advertising audio signals. The control signal and preferably the entertainment audio signal are modulated to a high-frequency carrier signal, possibly with several channels, for the separate recovery of the signals. The modulated carrier signal is transmitted, the transmitted carrier signal is demodulated and, if necessary, the signals are separated from each other. The pilot signals of the transmitted control signals are monitored for the presence of fading or flashback conditions.
