Abstract
A receiver is rapidly and accurately tuning a broadcast frequency and selecting a broadcast program by simple operation and also for clearly informing the user of receivable broadcast frequencies. Besides a number of broadcast programs, information indicating the transmission site position for the broadcast RF, the station name broadcasting that RF, the program name, and information showing whether or not the multiplexed program is a regional program matching a designated region, is also multiplexed on the digital audio broadcast and RF received and demodulated in a receiver section. When a broadcast radio wave is received from a tuned in station, a control section extracts the position information on the transmission site, the broadcast station name, and program name of the regional program from the radio wave and displays a mark indicating the position of the transmission site, the broadcast station name, and program name of the regional program on a map shown on an LCD display, based on the information that was extracted from the radio wave. Tuning of the desired broadcast radio wave and selection of the broadcast program is performed by the user specifying a position on a map.
