A reception state changes between a combining reception state and an individual reception state because of the determination of the optimum physical channel from a plurality of physical channels and combining diversity reception on the optimum physical channel. On the occasion of the change from the combining reception state to the individual reception state, when a control unit (120) consecutively changes a multiplier coefficient ATC from "1" to "0," the combining ratio of a channel selection signal (IFD1) to a channel selection signal (IFD2) in an adding section (173) consecutively changes from (1:1) to (1:0). Meanwhile, on the occasion of the change from the individual reception state to the combining reception state, when the control unit (120) consecutively changes the multiplier coefficient ATC from "0" to "1," the combining ratio of the channel selection signal (IFD1) to the channel selection signal (IFD2) in the adding section (173) consecutively changes from (1:0) to (1:1). As a result, even if there is any increase or decrease in antennas used for reproduction, the continuous and excellent reproduction of the content of broadcasting can be ensured. |
