METHOD OF RECORDING AND SORTING ALTERNATIVE FREQUENCES IN AN ALTERNATIVE FREQUENCIES REGISTER OF RDS RADIO RECEIFER AND RDS RADIO RECEIVER THEREFOR

摘要

Alternative frequencies for each radio data signal transmission are stored in a memory (100) alongside the corresponding reception quality, under corresponding program identifications (PI). The reception qualities are used as the selecting criteria for the alternative frequencies. A radio data signal receiver incorporating the alternative frequency selection method is independently claimed.
