The method of demodulation in an STB comprising a tuner including a local oscillator, a demodulator situated downstream of the tuner and a digital telephone base. In case of interference with the digital telephone base, the frequency of the local oscillator of the tuner is shifted by one or more synthesis intervals after scanning of an error indicator situated in the demodulator. This method makes it possible to insert a digital telephone base into an STB while circumventing disturbances in the operation of the STB when this base is transmitting.
