The invention provides a digital broadcast receiver which comprises a tuner 1 for selecting the desired broadcasting station from among a plurality of broadcasting stations, a demodulator circuit 3 for decoding a plurality of bit frames constituting the digital broadcast of the selected station, and a control circuit 4 for controlling the operation of the tuner and the demodulator circuit. With one broadcasting station selected, the control circuit 4 stops decoding at least one of the bit frames, and searches for other broadcasting station or stations of satisfactory reception condition utilizing free time resulting from stopping decoding. Upon the reception condition becoming impaired, the station being received is changed over to the station of satisfactory reception condition by the control circuit 4.
