Abstract:
A method for processing transmitter and program related data in an FM RDS receiver comprising the steps of:scanning a frequency band to detect FM RDS transmitters that exceed a threshold level; receiving signals from a first detected FM RDS transmitter that exceeds the threshold level and reading transmitter data and program related FM RDS data including a unique program identification code; storing transmitter data for each transmitter that exceeds the threshold level, wherein the transmitter data includes tuning data and a quality factor indicating a reception quality of the transmitter; storing program related FM RDS data for received transmitter data from the first detected FM RDS transmitter and allocating a linkage code to the transmitter data for the first detected FM RDS transmitter, wherein the linkage code defines a memory location for program data carried by the first FM RDS transmitter; and wherein program related FM RDS data including a program identification code is read from a second detected FM RDS transmitter and the program related FM RDS data from the second detected FM RDS is compared with the stored program related FM RDS data and if the program related FM RDS data from the second detected FM RDS transmitter is identical to the stored program related RDS data, allocating the linkage code defining memory locations for program data carried by the first FM RDS transmitter to the transmitter data from the second detected FM RDS transmitter.
