Abstract
A digital broadcast receiving apparatus has two systems as a receiving system: a first receiving demodulation section including a first tuner 2 and the like; and a second receiving demodulation section including a second tuner 5 and the like. A controller 19 establishes either a first receiving mode or second receiving mode. In the first receiving mode, both the receiving systems receive the broadcasting waves of the same station to be viewed according to the signals from a vehicle speed detecting section 15 and receiving level detecting sections 16 and 17. In the second receiving mode, one of the two receiving systems receives the broadcasting wave of the station to be viewed, and the other of them receives the broadcasting wave of another station.
