    Abstract: PROBLEM TO BE SOLVED: To manage whether individual information can be correctly supplied from broadcasting supply side to audience side. SOLUTION: A broadcasting program, common information, and individual information are outputted as a transmission signal DSS from an transmitter 10 on the broadcasting supply side. Reception terminal 30 on the audience side stores prescribed information included in received individual information destined for equipment itself. This prescribed information stored in the reception terminal equipment 30 is supplied to transmission equipment 10 through, for example, a public telephone line. The transmitter 10 compares transmitted individual information with supplied prescribed information to manage whether individual information is correctly supplied to reception terminal 30 or not. Since it is sufficient if individual information is transmitted in the case of update of stored information or non-coincidence of information, it is unnecessary to transmit individual information to reception terminal 30 many times, and broadcasting programs or the like are efficiently transmitted.

    Abstract: PROBLEM TO BE SOLVED: To make it difficult to execute wire tapping, and to easily attain reception in a normal device. SOLUTION: A video signal received by a receiving circuit 21 is extracted through a de-scramble circuit 22 to an output terminal 23. A voice signal received by the receiving circuit 21 is supplied through a separating circuit 24 to a de-scramble circuit 25, and extracted to an output terminal 26 after arbitrary bit inversion or the like is restored. Moreover, key signals K4 and K3 from a memory 37 are supplied to random signal generating circuits 41 and 42 as initial values, and a frame synchronizing signal from the separating circuit 24 is detected by a detecting circuit 43, and supplied to generating circuits 41 and 42. Then, generated random signals are selected by a switch 44, and supplied to the de-scramble circuit 25 and a subtracter 27, and a flag (identification signal) indicating the switched state of the switch from the separating circuit 24 is supplied to a switching signal generating circuit 45, and the switching of the switch 44 is controlled according to a signal from the generating circuit 45.

    Abstract: PROBLEM TO BE SOLVED: To reduce the cost and to save installation space as a whole. SOLUTION: A tuner 30 receives a signal of a pay broadcast that is broadcast via a satellite, and a decoder 40 decodes the signal and outputs it to an output section 70. A memory 54 stores the view history of the pay broadcast. A MO DEM 43 transmits the view history to a center station via a public network 6. Furthermore, a MODEM 43 receives a facsimile signal sent from a facsimile terminal and the reception information conversion section 81 of a facsimile information processing section 80 converts the facsimile signal into an image signal. The converted image signal is fed to an output section 70 and displayed.

    Abstract: PROBLEM TO BE SOLVED: To forcedly limit programs not to be observed by children or the like. SOLUTION: A block control part 56 compares a password stored in an EEPROM 55 with a password inputted by operating an input part 47, and only when both passwords coincide with each other, a scramble key is supplied from a decoder 43 to a descrambler 44. Consequently a program received by a tuner 30 is descrambled. The password stored in the EEPROM 55 is constituted so as to be updated only when a clear flag is stored in the EEPROM 55 and the clear flag is transmitted when a parent or the like communicates to a broadcasting station (center station).

    Abstract: PURPOSE: To prevent easy descrambling by improving secrecy. CONSTITUTION: An initial value amending circuit 2 amends the initial value supplied from an initial value register 1 and supplies it to a PRBS generation circuit 3. This circuit 3 generates a PN signal (pseudo random sequence) based on the amended initial value and outputs it to an adder 12. The adder 12 adds this PN signal to inputted packet data to output enciphered (scrambled) packet data. A control circuit 23 controls the PRBS generation circuit 3 for each packet based on the packet ID (PID0 to PID13) detected by a detection circuit 22, a continuation counter (CCT0 to CCT3), or the initial value and switches taps of a feedback shift register incorporated in the PRBS generation circuit 3 and the operation of a nonlinear logic.
