摘要： An apparatus for receiving broadcasting signals, which comprises a signal receiving portion for receiving a broadcasting signal, a frequency convertor for the broadcasting signal received by the signal receiving portion, an IF amplifier, an A/D convertor, a digital demodulator, a program selector for selecting one of plural groups of program information data obtained from the digital demodulator, an information reproducing portion for reproducing program information, and an operation controller operative to put at least each of the signal receiving portion, the frequency convertor and the IF amplifier in a reduced power consumption state in periods other than a period in which portions of the broadcasting signal, which carry the synchronous data, the control information data and the program information data to be selected by the program selector, respectively, are able to be received by the signal receiving portion.

摘要： PROBLEM TO BE SOLVED: To provide e.g., an on-vehicle terrestrial digital broadcast receiver capable of securing high image quality and a broad reception area by outputting a contents signal with high image quality for a fixed terminal when the reception quality is excellent and outputting a contents signal with low image quality for a mobile terminal when the reception quality is insufficient. SOLUTION: The receiver 10 is provided with: a switching section 17 for switching a voice signal for a layer A (for mobile reception) and a voice signal for a layer B (for fixed reception); and a control section 18 for controlling the switching section 17. The control section 18 references the S/N of a received signal, outputs the layer B voice signal when the reception quality is excellent, and outputs the layer A voice signal when the reception quality is not excellent. Further, the control section provides a hysteresis to the threshold value of the S/N for switching between the layers A and B, and performs switching to the layer B, when the moving average of the S/N is increased even when the S/N is smaller than the threshold value, in the case of switching the layer A into the layer B.

摘要： PROBLEM TO BE SOLVED: To provide a broadcast receiving system capable of receiving an analog broadcast and a digital broadcast stably through a common antenna. SOLUTION: The broadcast receiving system is equipped with an antenna array 10, an analog broadcast receiving means 200, and a digital broadcast receiving means 300 and capable of receiving the analog broadcast and the digital broadcast. The antenna array 10 is composed of a plurality of antennas to receive radio waves, the analog broadcast receiving means 200 receives signals selectively through the antennas of the antenna array, and the digital broadcast receiving means 300 is so constituted as to compound and receive signals through, at least, two or more antennas out of the antenna array 10.
