Abstract
A digital broadcasting receiver that uses a channel map containing broadcast information such as channel numbers and virtual channel numbers is described. When a user selects a certain digital channel number, a control unit consisting of a CPU makes a search as to whether or not the number exists in the channel map. If the number does not exist, 'No Signal' notice is displayed on a display and if the user selects a scan instruction then, the entire range of frequency band of the broadcasting signal is scanned. If a signal that corresponds to the digital channel number exists, its broadcast is received. Therefore, a search is possible even when the user knows only a virtual channel number and the digital channel number entered by the user is not registered in the channel map.
