摘要： When performing switching control of reception modes trading off reception sensitivity against power consumption in a reception environment, the receiving apparatus and control method of the present invention perform state transition without a reception error occurring due to switching control with the aid of a reception mode in which an intermediate reception performance is provided. The present invention is particularly useful to balance the reception performance with the battery duration in a battery-powered, portable receiving terminal such as a television receiver for a mobile terminal.

摘要： The demodulator in the receiving module of the invention supplies a signal produced based on a signal level detected by a first detector to a second amplifier as an amplification degree adjustment signal. With this arrangement, when a second receiver works, an AGC voltage supplied to the second receiver is already close to an ultimately converging certain value. The AGC voltage supplied to the second receiver is thus stabilized in its value, from the value close to the ultimately converging certain value to the certain value. Accordingly, a time period required from the second receiver starts working until the AGC voltage supplied to second amplifier ultimately converges into the certain value is shortened.

摘要： A receiver according to the present invention includes a first receiving (RCV) quality detector and a second RCV quality detector connected before a combining unit. The second RCV quality detector determines a quality of a signal output from at least one of a first receiving unit and a second receiving unit by a method different from that of the first RCV quality detector. A controller allows the receiver to operate in a single receiving mode when a determination result of the second RCV quality detector is not better than a predetermined level regardless of a determination result of a determination result of the first RCV quality detector not being a predetermined level. When the receiver passes in an area where the receiver cannot receive a broadcast signal, the determination result of the second RCV quality detector is not better than the predetermined level. In response, the controller allows the receiver to operate in the single receiving mode, thereby reducing power consumption of the receiver.

摘要： In a digital broadcast receiver, when a bit error rate (BER) is larger than a threshold in a BER determining part, power is supplied to a first tuner and a second tuner for diversity reception. When the BER is smaller than the threshold, power supply to one of the first tuner and the second tuner is stopped for single reception. This structure allows power supply to one of the tuners to be stopped in excellent reception environments, thus reducing power consumption.

摘要： Provided is a reception device that selectively receives an analog broadcast signal and a digital broadcast signal. The reception device includes: an oscillation unit operable to output an oscillator signal; a frequency conversion unit operable to output an IF (Intermediate Frequency) signal group based on the oscillator signal outputted from the oscillation unit and a reception signal; a filter unit connected to an output side of the frequency conversion unit; and a control unit operable to control a frequency of the oscillator signal outputted from the oscillation unit. The control unit controls: the frequency of the oscillator signal to be within a reception frequency band when receiving the digital broadcast signal; and the frequency of the oscillator signal to be outside the reception frequency band when receiving the analog broadcast signal. With this configuration, it is possible to improve reception quality when receiving an analog broadcast signal.
