  • RECEIVING APPARATUS, METHOD OF CONTROLLING APPARATUS, AND PROGRAM FOR IMPLEMENTING THE METHOD
    Publication number: 20080218637
    Abstract: A receiving apparatus for receiving a digital television broadcast includes an amplification unit that amplifies radio frequency signals supplied from an antenna at a predetermined gain to output the amplified radio frequency signals, a channel selection unit that selects a broadcast wave from the radio frequency signals output from the amplification unit to produce output signals, a demodulation unit that processes the output signals to demodulate content data transmitted on the broadcast wave, and a control unit that controls the gain of the amplification unit so that the signal level of the output signals becomes a predetermined value. The control unit controls the gain of the amplification unit using the control start value and changes the control start value in accordance with the result of processing by the demodulation unit.
