摘要： PROBLEM TO BE SOLVED: To provide a receiver which normally receives even in a receiving environment with a multi-path. SOLUTION: A comparator 18 compares, with a threshold of a predetermined range, an output from an integrator 17 which integrates a detected frequency offset value that is detected by a frequency offset detector circuit 7 based on a reference symbol for frequency offset detection a changeover switch circuit 10 selects a detection frequency offset value that is detected by a frequency offset detector circuit 8 based on a phase difference of a delay detection output when an output of the integrator 17 is within the range of the threshold, and selects a detection frequency offset value that is detected by the circuit 7 when an output of the integrator 17 is not within the range of the threshold, and automatic frequency control is performed based on a selected detection frequency offset value.

摘要： PURPOSE: To properly perform charging processing based on reception control information even without loading an information storage medium on a main body at all times by reading and storing the reception control information from the loaded information storage medium. CONSTITUTION: It is discriminated whether data HRD for RAM check are '10100101' or not. At such a time, when the condition of HRD≠10100101 is established and an abnormal operating state is provided, it is displayed on a display part 6 for five seconds that 'Data of main body are broken. Data are initialized from now. Exchange backup battery immediately.' Next, after '0' is written in a RAM 47 at the main body and it is initialized, '10100101' showing a normal operation is written in a RAM function check area. When an IC card is loaded and a flag JKF of the IC card 2 is '1' to show the use of a transfer function, date data JSYD and JSDD of the end of transfer are written and copied as areas HJSY and HJSD. Further, a transfer function flag HJKF=1 is set.

摘要： PURPOSE: To easily read the display by providing a constitution where a display part main body includes a control means, a storage means, an operation means and a display means and then shows the information stored in the storage means on the display means by itself even when the display part is detached from a receiver. CONSTITUTION: When a display part main body 20 is not attached to a receiver main body 10, the flow of information is stored in a storage circuit 105 only. When the body 20 is attached to the body 10, a signal control circuit 104 is connected to a control circuit 204. The information data sent from a multiple signal decoder circuit 102 are not continuously transmitted in terms of time but arranged and pooled for a fixed time. Therefore, the circuit 104 monitors the time band where the information data sent from the circuit 102 are stopped and also transfers the data on the contents of the circuit 105 to a storage circuit 202 via the circuit 204. Then the body 20 is actuated only when the data are completely transferred to the circuit 202 and also the coincidence of storage contents is secured between both circuits 202 and 105.

摘要： PURPOSE:To obtain the optimum output form of an audio signal even if a user does not select an audio mode in a television receiver, especially in a high image quality television receiver. CONSTITUTION:A matrix circuit 11 is controlled so that CPU 101 discriminates the number of channels which a main audio signal in the channels CH1-CH4 of a pre-selection audio signal 8 occupies in accordance with an audio mode signal included in a bit stream signal 9 when only the main audio signal or the main audio signal and an auxiliary audio signal or an independent audio signal distribute and output the pre-selection audio signals 8 into the speakers 2, 3, 4, 5 and 6 of the plural channels in accordance with plural audio modes, an audio output system for reading information stored in a memory 103 in accordance with the discriminated number of the channels and outputting the audio signal is selected and main audio output is distributed to the selected audio output system.

摘要： PURPOSE: To decrease the number of pins of a chip and to reduce the stray capacity of a signal system by removing a capacitor for signal transmitter interposed between an AM amplifier and an amplifier and using a ground type capacitor. CONSTITUTION: An FM detector 100 detects an FM wave. A BPF 200 filters the FM-detected signal to detect a specific pilot signal. The AM detector 300 detects an AM wave modulated into the pilot signal. A capacitor 600 reduces a DC component superposed on the detected AM wave in an amplifier 400. The amplifier 400 amplifies the output signal of the AM detector 300 and the AM wave of the detected AC component. Namely, the capacitor 600 is coupled between the common node of a resistance 500 and the amplifier 900, and a ground voltage so as to hold a proper DC level of the amplifier 400 even if the output of the detector 300 varies, and then the output signal of the amplifier 400 and the signal from the common node are used as an input to a phase detector 900, so that the DC component can be removed.
