Receiving device and receiving method

A receiving device comprising:

• at least one distributor that distributes a high-frequency signal received by an antenna;
• a high-frequency processing unit configured to output a received signal obtained by mixing the high-frequency signal distributed by the distributor with a local oscillator frequency generated by a local oscillator that includes a voltage-controlled oscillator;
• and
• a control unit including a processing unit configured to execute a local oscillator frequency calibration to investigate a correspondence between a control voltage applied to the voltage-controlled oscillator and the local oscillator frequency of the voltage-controlled oscillator, and when executing the local oscillator frequency calibration, to determine whether another tuner in the receiving device is active and, in response to determining that another tuner is active, to set to a dormant state parts of the local oscillator that are uninvolved in operation of the local oscillator frequency calibration and, otherwise, to end the local oscillator frequency calibration, wherein
• the parts set to the dormant state during the local oscillator frequency calibration include a mixer that mixes the high-frequency signal distributed by the distributor with the local oscillator frequency generated by the local oscillator, and an amp that amplifies the high-frequency signal mixed by the mixer.
