Abstract

Method for the radio transmission of encoded data superimposed on a traditional frequency modulated broadcast, consisting of: modulating the encoded data being transmitted, by frequency displacement, in a predetermined frequency band between approximately 15 and 18 kilohertz to create modulated encoded signals mixing the modulated encoded signals with the low- frequency signals of the traditional program, transmitting the mixed signal with a frequency modulated radio transmitter 20, maintaining the frequency shift of the modulated encoded signals by frequency displacement, expressed in hertz, with respect to the transmission rate of the encoded data being transmitted, expressed in baud, between approximately 85 and 120 percent. The method further comprises the step of attenuating the modulated encoded signals by approximately 20 to 40 decibel relative to the instantaneous transmission level of low-frequency signals of a traditional program, controlling the rate of attenuation of the modulated encoded signals continuously with respect to the instantaneous level of the low-frequency signals of the traditional program.
