ABSTRACT:
There is provided a digital broadcasting receiver capable of making channel selection without making a user conscious of the difference between a physical channel number and a virtual channel number. A CPU uses an OSD display circuit, for example, to display a menu screen, and causes a user to select either a first mode or a second mode. The first mode is a mode for making channel selection by the physical channel number in which a frequency is assigned to a channel by the physical channel number in accordance with a rule, and a second mode is a mode for making channel selection by the virtual channel number in which a frequency corresponds to a channel on the side of the receiver. The CPU automatically makes, when no channel selection can be made by the entered channel number in the selected mode, an attempt to make channel selection corresponding to the other mode.
