Abstract: A broadcast reception device includes a storage unit, a viewing period measurement unit that measures a period of viewing a program, a program classification unit that classifies a viewed program based on a predetermined program classification, a viewing period accumulation unit that accumulates the period measured by the viewing period measurement unit based on the type classified by the program classification unit, and stores the accumulated period in the storage unit, and a display information generation unit that displays the accumulation information of the viewing period stored in the storage unit in predetermined timing on a display device.

Abstract: An audio muting apparatus including a control device 3 for gradually varying a converted output voltage 12 from a D/A converter 4 from an initial voltage to a prescribed voltage when performing muting and gradually varying the converted output voltage from the prescribed voltage to the initial voltage when releasing the muting. A muting section 5 for passing an audio signal in such a manner that an impedance between an audio signal path and a ground level is increased when the converted output voltage 12 becomes the initial voltage and interrupting passage of the audio signal in such a manner that the impedance between the audio signal path and the ground level is decreased when the converted output voltage 12 becomes the prescribed value.

Abstract: In a temperature measuring circuit connecting a temperature sensor such as a thermistor to a standard voltage source through tap resistances, detecting a sensed value of the temperature sensor by comparing the voltage of the sensor connecting point with the specified voltage by a comparator, a simplified construction of the circuit makes it possible to detect failures of the temperature sensor such as breakage or burn-out.
