摘要： Picture quality deterioration that occurs during channel transition is reduced in an apparatus having a plurality of tuners. A receiver apparatus includes a receiving unit 300 configured to select a signal of a desired channel from respective received signals split by a splitter unit that splits the received signal into at least two or more signals, and to obtain an intermediate frequency signal or a baseband signal. The receiver apparatus further includes a local oscillator unit 305 configured to generate a frequency signal necessary for the receiving unit 300 to generate the intermediate frequency signal or the baseband signal, and to supply the generated frequency signal to the receiving unit 300, and a PLL unit 310 configured to generate a frequency control voltage for controlling an oscillating frequency of the local oscillator unit 305. The receiver apparatus further includes a control unit 40 configured to perform a control of decelerating the speed of changing the frequency control voltage by the PLL unit 310 when the receiving unit 300 changes its reception channel and it is detected that the changed channel crosses a channel that is being selected by another receiving unit that receives the received signals split by the splitter unit.
