Abstract
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.

A method of demodulation in a receiver/decoder comprising a tuner including a local oscillator, a demodulator situated downstream of the tuner and a digital telephone base wherein, 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 signal given by the error indicator situated in the demodulator.
A receiver/decoder comprising a tuner including a local oscillator, a demodulator situated downstream of the tuner and a digital telephone base, wherein it furthermore comprises a software program means for scanning an error signal issued from the error indicator situated in the demodulator, which acts so as to control the shifting of the frequency of the local oscillator of the tuner when the telephone base interferes with the local oscillator.
