Patent ID: 8009767

Claim:
A digital demodulating apparatus comprising: a tuner that performs channel select processing to a received signal; a demodulator that performs demodulation processing to the received signal from the tuner; a controller that controls the tuner and the demodulator; a signal status forecasting section that, when a predetermined control is to be performed by the controller, forecasts a change in signal status attributed to the predetermined control prior to the controller performing the predetermined control, based on a type of the predetermined control; and an operation controlling section that, when the signal status forecasting section has forecasted that the signal status is to be worsened to a predetermined status due to the predetermined control, controls demodulation processing of at least one of a plurality of circuit elements that constitute the demodulator, such that a performance of the demodulation processing decreases in processing a portion of the received signal in which the signal status has been forecast as worsened.
