First Claim
Patent Images
1. A radio receiver, comprising:
- an FM band tuner;
an AM band tuner;
a controller coupled to both the FM band tuner and the AM band tuner; and
a radio data decoder for providing radio data, where the radio data decoder is coupled for receiving radio data from at least one of the tuners which is tuned to a radio program, whereinthe radio receiver comprises an radio data memory coupled to the radio data decoder, where the memory at least contains radio program frequency correspondence data,the radio receiver is designed to store radio program frequency correspondence data in the memory during presence in the FM band and to use the radio program frequency correspondence data later for switching back from the AM band, andthe radio data decoder is coupled to the controller for automatically switching the radio receiver from the FM band to the AM band or vice versa based on the radio program frequency correspondence data included in the radio data, wherein a same radio program is broadcast on both the FM and AM bands.

Abstract
A radio receiver having an FM band tuner, an AM band tuner, a controller coupled to both said tuners, and a radio data (RD) decoder for providing radio data. The RD decoder is coupled for receiving radio data from at least one of the tuners which is tuned to a radio program. The RD decoder is coupled to the controller for switching the radio receiver from FM band to AM band or vice versa based on radio program frequency correspondence data included in the radio data. The radio receiver is advantageous since it allows for automated cross switching between different frequencies whereon a same radio program is broadcast. This is particularly advantageous if the radio receiver, such as placed in a car, leaves the broadcast coverage area. User intervention is thus obviated.
