Abstract (en)
[origin: WO2006056528A1] The invention relates to a method for broadcasting a digital signal transmitted in the vicinity of an analog signal carrying a source audio signal modulating the amplitude of an AM carrier. According to the invention, this method comprises an amplitude-modulation step in the frequency domain of the digital signal carried out by a masking signal representative of a psycho-acoustic masking curve of the source audio signal.
