摘要

A receiving frequency selecting method is an RDS receiver. Even if a same network station cannot be selected by the network following function, a broadcasting station of the same program is automatically searched. Thus, the possibility that a broadcasting station of the same program can be received can be improved. If the same PI (program identification) data has been taken a plural number of times upon AF (station frequency) check, by executing the PI check even if a predetermined time has not elapsed, the PI check can be performed in a short time and disturbance of a listener can be reduced. <IMAGE>
