  • Patent number: 6560207
    Abstract: Data counters and perform a counting operation which is synchronized with the respective timing of receiving multiplex data from a VICS data broadcasting station and a D-GPS data broadcasting station. While receiving the multiplex data from the VICS data broadcasting station, based on an output C2 of the data counter and a BIC detection output BP, block synchronization is detected. When the broadcasting station is switched from the VICS data broadcasting station to the D-GPS data broadcasting station, an output C2 of the data counter is selected in response to a control signal CONT and block synchronization is detected based on an output C2 and an output BP. Further, an output C1 is always inputted to the block counter. Thus, even while receiving the multiplex data from the D-GPS data broadcasting station, frame synchronization of the multiplex data of the VICS data broadcasting station is detected without causing miscounting.

  • Patent number: 6363063
    Abstract: A receiver receives FM multiplex broadcast data of both RDS and DARC systems by using one front end. A BIC detection circuit (101) detects a block identification code (BIC) included in received data. A coincidence/non-coincidence detection circuit (104) judges whether or not a BIC detection timing is correct and emits a coincidence/non-coincidence pulse. A forward protection circuit (106) counts a frequency of outputs of non-coincidence pulses and retains an established synchronous condition until the counted value exceeds a predetermined value. Then, a forward protection control circuit (108) inhibits the forward protection circuit from performing a count operation while a search is performed for selecting a station. Also, a rearward protection circuit (105) counts a frequency of outputs of coincidence pulses and establishes a synchronous condition when the counted value reaches a predetermined value.

  • Patent number: 6345245
    Abstract: A common dictionary management system that can reduce the work of data registration into dictionaries. Exchange data generated in any local dictionary of a natural language processing system is sent to the local dictionaries of other natural language processing systems automatically. A local dictionary management portion and a common dictionary management portion collect updated dictionary data from a plurality of local dictionaries and updating time information. The local dictionary management portion updates the common dictionary and the local dictionaries according to the collected dictionary data and the time information. The local dictionary management portion compares the information with the latest time on which dictionary data was distributed to the local user dictionaries with the updating time information of the dictionary data in the common dictionary to distribute the dictionary data of the common dictionary selected according to the result of the comparison, to the local dictionaries.

  • Patent number: 6288583
    Abstract: For frequency change, the VCO is controlled through a sub-charge pump circuit to make a determination as to whether or not a difference of dividing data between before and after the change is within a predetermined range. When it is determined that the difference is outside the predetermined range, the loop filer is forcibly charged in a charge time which is determined proportional to the difference in the dividing data, to thereby control an oscillation frequency of the VOC. A large VOC oscillation frequency change can be swiftly realized. Also, while the frequency change circuit is controlling the oscillation frequency, a time constant of the loop filter in the PLL circuit is preferably set at a small value, so that frequency change by the frequency change circuit can be swiftly achieved.

  • Patent number: 6256359
    Abstract: Received signals are digitized by a comparator, and sampled by regenerated clock signals synchronized to a carrier. Biphase symbol data are demodulated based on the sampling data. A biphase decoder circuit performs subtraction of the biphase symbol data to be paired. The subtraction result is compared with threshold values by data judgment circuitry which then judges inversion of the biphase signals to be paired. An RDS-ID detector circuit detects inversion of RDS signals by detection of either continuity or a ratio of signals received for a certain length period. Alternatively, RDS signals are detected by stability of output from the pair judgment circuit to detect a combination of biphase symbols.

  • Patent number: 6128390
    Abstract: A second random number generator (102) sets a scramble key data included in a transmitted/received data to an initial value, and it generates predetermined second random numbers. A first random number generator (101) generates first random numbers from the second random numbers supplied by the second random number generator (102). The generation of the first random numbers by the first random number generator (101) is controlled by an output from a first control circuit (103). Since the output from the first control circuit (103) is changed in accordance with a service identification code SI, the first random numbers generated from the first random number generator (101) are changed. The first random numbers are input to a gate circuit (105) via a second control circuit (104). The second control circuit (104) inhibits the output of the first random numbers in accordance with the SI value. In such a manner, scrambling or descrambling is controlled in the gate circuit (105).
