Abstract
PURPOSE:To contrive the prevention of a mis-operation by reading an identification code obtained through the reception of a radio digital system broadcast wave for plural number of times so as to confirm whether or not the content of read is consecutively the same, thereby discriminating the content of a code signal accurately. CONSTITUTION:A processor receives a data fed from an error correction circuit 13 so as to discriminate whether or not a flag FTP representing the reception state of a broadcast wave broadcasting traffic information is equal to '1'. In case of FTP='0', whether or not the content of a TP code in an input data is '0' is discriminated and a counted value CT is set to a 1st prescribed value, because no broadcast wave is being received. If the TP code is set to '1', the change of the counted value CT from 0 to 1 is confirmed. The TP code is discriminated to be at '1' by the number of times of the 1st prescribed value to discriminate the reception of a broadcast wave broadcasting traffic information, thereby setting the flag TP to '1'. In case of TP code ='1', the count G is set to a 2nd prescribed value larger than the 1st prescribed value.
