摘要： In a packet analyzing circuit, first and second key data are detected and stored in respective first and second key data registers. First and second key generation circuits generate first and second keys from the first and second key data. An exclusive OR operation is carried out to both keys so as to generate a scrambling key. Using the scrambling key as an initial value, a random number generator generates a PN code used for scrambling, so that scrambled data is descrambled by adding the PN code to the data. The first key generation circuit, which receives a control signal CON from a timing generation circuit, is controlled by the control signal CON such that a scrambling key is generated only when the random number generator needs an initial value.

摘要： A scrambling key is generated from demodulated and error-corrected FM demodulation data for use in descrambling. During this process, if error correction has not been normally conducted to an object data packet, a subsequent descrambling operation is not executed to that data packet. In addition, a descrambling operation is not carried out if the object data packet is a parity packet.

摘要： In a decoding processing circuit of a digital signal receiver, a first comparison circuit detects that a prefix of packet data is inputted in a shift register on the basis of a count value of a counter circuit. In response to the result of detection, a pseudo-random binary sequence generation circuit outputs a pseudo-random binary sequence on the basis of a data group number and a data packet number outputted from the shift register and key data previously extracted by a key data fetch circuit. When a second comparison circuit detects that block data in the data packet is inputted in the shift register, an exclusive OR circuit exclusively ORs the pseudo-random binary sequence with receive data, so that decoded data is inputted in the shift register.

摘要： The credit card information management system checks the creditability of a credit card intended to be used for purchase of goods or service by using the card information owned by member stores of credit companies. A host computer of the card management center outputs information regarding the validity or invalidity of a credit card of a customer member of a credit company as card information, a transmission facility wirelessly transmits digital data of the card information. A receiving facility of a member store receives radio signals of the card information and checks whether or not there is any missing of data. If any missing occurs, a transfer of the missed data is requested to the host computer. A terminal computer extracts only the card information necessary for one's own store from the data outputted by the host computer and data outputted in response to the transfer request and stores the same in memory, and the terminal computer outputs judgement of validity or invalidity of a credit card inputted into a card reader.

摘要： An FM multiple radio broadcasting receiver includes a data group number and data packet number derivation circuit by which a data group number and a data packet number included in a prefix of FM subcarrier data are derived. A first random number generator generates a first random number on the basis of the data group number, the data packet number and scramble key data which is outputted from a scramble key generation circuit, and sets the first random number in a second random number generator as its initial value. Therefore, it is possible to appropriately scramble or descramble with using packet structure of the FM subcarrier data.

摘要： A frame-synchronous reproducing circuit (10) includes a BIC status register (20) of six stages, and a BIC status signal (c) from each stage of the register is applied to a BIC pattern determination circuit (24) in which the BIC status signal (c) and a BIC changing pattern being stored in advance are compared with each other. If the both are coincident with each other, the BIC pattern determination circuit (24) applies a high-level signal to a JK flip-flop (26) via an OR circuit (48), whereby a high-level signal representing that frame synchronization has been settled is outputted from the JK flip-flop (26).

摘要： An FM multiplexed broadcasting signal received by an antenna and FM-demodulated by an FM tuner portion is demodulated by a demodulation LSI into a digital signal corresponding to packet data. The digital signal is successively supplied by every packet to a CPU of a receiving portion. The CPU of the receiving portion removes unnecessary data of the received data and then supplies only data required for a CPU of a personal computer via a buffer without delay from the reception. When a transferred packet is a successive reproduction program packet or a time information packet, the CPU of the personal computer calculates latency required before a predetermined data analysis processing is started, and performs data analysis processing in an elapse of the latency. Responsively, reconfiguration of program data is performed and corresponding character information or the like is output to a displaying portion.
