Abstract (en)

[origin: DE4441789C1] The data recognition system is used to identify a cyclically repeating data bit sequence in the received radio data signal (RDS), by evaluation of a section of the received data stream covering a number of cycles. The static evaluation provides the individual bit positions of the evaluated cycle, the corresponding bit sequence evaluated using a radio data signal block identification algorithm, to identify the radio data blocks. Pref. each bit position of the evaluated cycle is assigned a value of '0' when less than half of the examined cycles have a value of '1' at this bit position and a value of '1' when more than half the examined cycles have a value of '1' at this bit position.
