A digital tuner performs, when it receives a command to tune in on a digital broadcasting channel by a remote control signal, processing for tuning in on the digital broadcasting channel by the command. A broadcasting receiver enters a digital broadcasting received/video displayed state by the digital tuner. At this time, in an analog tuner, a local oscillation frequency on a channel at the time of viewing is not maintained but is changed and set to a frequency for selecting the highest channel 125 in CATV, thereby preventing interference with the digital tuner.
