Abstract: PURPOSE:To obtain a signal transmitter with high general-purpose performance and the signal transmission system employing said signal transmitter in which the circuit configuration set once is not required to be revised and the function is easily increased/decreased on user's requirements. CONSTITUTION:An input signal from an input terminal 10 and an external input signal from an external RF input terminal 14 are fed to a modulation section 11a in a frequency multiplexer section 11. The modulation section 11a uses the input signal to modulate a carrier signal whose frequency different from that of an external input RF signal with a carrier frequency setting signal from a controller 12. The carrier signal and the external input RF signal are mixed by a mixer circuit 11b to apply frequency multiplexing and the resulting RF signal is outputted from an output terminal 13.

Abstract: PURPOSE:To perform a self-diagnosis without a need for a special in jig and to detect an abnormal part in each circuit block even during the operation of an apparatus. CONSTITUTION:A tuner 3 selects an RF signal in one band out of frequency- multiplexed RF signals, and it converts the RF signal into an IF signal. A demodulation circuit 4 demodulates the IF signal and it outputs signal data. A demultiplexer 5 releases a time-division multiplex, it takes out data at one frame, it performs an error-correction decoding processing operation, and it takes out an audio channel and a data channel. An expansion circuit 6 performs an expansion operation and a volume operation. A microprocessor 9 performs the self-diagnosis of the tuner 3, the multiplexer 5, the expansion circuit 6, a D/A converter 7 and an amplifier 8 in a test mode. In addition, the microprocessor 9 performs a tuning operation by the tuner 3 and a muting operation or a muting release operation on the basis of the result of an error processing operation by the multiplexer 5 in an ordinary operation.

Abstract: PURPOSE:To stably operate plural frequency-divided signals up to a high frequency by using the plural frequency-divided signals of specific % duty as the clocks of a normal IC and other circuits. CONSTITUTION:JK-FFs 11 and 12 frequency-divide an input clock to three, the JK-FF 11 sets the JK-FF 13 at the time t1 and the JK-FF 12 clears the JK-FF 13 at the time t4. Thus, the JK-FF 13 output the three-frequency-divided signal for which the input clock is frequency-divided to three with the duty of 50%, for instance.

Abstract: PURPOSE:To surely detect the timing of reference data by sending out continuously at least two times reference data of N bit length from a data transmission system, and detecting the coincidence of the received N bit data and the N bit data received immediately before by a data reception system. CONSTITUTION:Reference data of N bit length formed by a prescribed pattern is send out continuously two times into digital data SDAD from a data transmission system 2, and the digital data SDAD is received with an N bit unit by a data receiving system 4 so that the coincidence of the received N bit data and the N bit data received immediately before can be detected. In such a manner, the timing of the reference data can be detected surely, and since the pattern of the reference data can be changed momentarily, the privacy property can be improved remarkably.

Abstract: PURPOSE:To execute the scramble based on scramble data varying an inputted video signal for each prescribed period by reading out the scramble data written in the other memory, while writing the inputted scramble data in one memory of a storage means, and supplying the scramble data to a scramble means. CONSTITUTION:While writing inputted scramble data SDA in one memory 22 (or 23) of a storage means, the scramble data SDA written in the other memory 23 (or 22) is read out, and supplied to scramble means 15, 15, 17 and 18. In such a manner, the scramble can be executed based on the scramble data SDA varying an inputted video signal SVDO for each prescribed period T with a simple constitution.

Abstract: PURPOSE:To halve the memory capacity to a conventional capacity by writing a digital information signal in one and the same address after a memory having a capacity corresponding to a replacing range of the signal is read, repeating twice the replacement and applying designated address control. CONSTITUTION:A composite color video signal fed to an input terminal 1 is subject to band limit by a pass filter 2 and quantized by an A/D converter 3 and fed to a field memory 4. An address conversion circuit 8 generates a scanning line address in response to a chaffling pattern from a chaffling data table 6. Two chaffling patterns are fed alternately to the address conversion circuit 8 at each field. Just after plural sampling data included in one scanning line designated by the scanning address from the address conversion circuit 8 are read out of the memory 4, plural sample data are written therein at the same scanning line address. The data read from the memory 4, that is, the chaffled data is fed to a control data inserting circuit 9.

Abstract: PROBLEM TO BE SOLVED: To attain an authentication system which makes a one-time password generation means portable and does not burden a user. SOLUTION: In the system which authenticates a terminal 10 communicably connected with an IC card 50, time information acquired from the terminal 10 by the IC card 50 is decrypted and encrypted by pregiven keys A, B, respectively, and an operation result α is transmitted to the terminal 10 as a response. The terminal 10 transmits the operation result α to an authentication server 40 as authentication data together with a user ID and the time information. In the authentication server 40 the authentication data including the user ID, operation result α, the time information are received, the time information is decrypted and encrypted by using the keys A, B in the authentication server 40, respectively. Then, the encryption processed time information is collated with the operation result α transmitted by the terminal 10 and when this collation result matches, connection between the terminal 10 and the authentication server 40 is permitted.
