Abstract
A first switching circuit (21) outputs a first radio signal representing a plurality of time-division multiplexed programs and a second radio signal other than the first radio signal, one at a time according to a switching signal. A voltage control oscillator (27) outputs a local signal at a frequency suitable for whichever signal outputted. Using the local signal generated, a frequency converter (24) frequency converts the first and second radio signals to first and second baseband signals, respectively. Via a second switching circuit (31), a first baseband unit (40) and a second baseband unit (50) are supplied with the first and second baseband signals, respectively, and demodulate them to first and second data signals. A switching unit (60) supplies the switching signal indicating periods during which the first radio signal represents a user-selected program, to a tuner unit (20) where the first and second radio signals are processed by time-sharing.
