  • Patent number: 8330872
    Abstract: A receiving apparatus is disclosed which includes: an amplification section configured to amplify a received signal including a digital broadcast signal; a mixing section configured to mix the received signal amplified by the amplification section with a selective frequency signal so as to acquire an intermediate frequency signal; a demodulation section configured to demodulate the intermediate frequency signal acquired by the mixing section so as to acquire a demodulated signal of the digital broadcast signal; and a control section configured to control the amplification factor of the amplification section in a manner bringing to a target level the signal level of the intermediate frequency signal acquired by the mixing section, the control section being further configured to set variably the target level in accordance with bit error status of the demodulated signal acquired by the demodulation section from the digital broadcast signal.

  • Publication number: 20110134337
    Abstract: 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.
