RDS-TMC radio receiver for processing region-specific and supra-regional road or area indications
First Claim
1. A radio receiver comprising a control circuit (7)for supplying coded messages derived from a radio signal to at least one memory arrangement (12, 28),for receiving control data derived from the coded messages and originating from at least one memory arrangement (12, 28), andfor forming messages from the control data in a form suitable for a visual display (13) and/or a voice output circuit (14), characterized in that a reading device (16) for reading data from an external first memory arrangement (28), and a second memory arrangement (12) are coupled to the control circuit (7), and in that the first memory arrangement (28) is used for storing control data for region-specific road or area categories and the second memory arrangement (12) is used for storing control data for supra-regional road or area categories, which categories have each a respective class name.

Abstract
The invention relates to a radio receiver comprising a control circuit (7) for supplying coded messages derived from a radio signal to at least one memory arrangement (12, 28), for receiving control data derived from the coded messages which control data originate from at least one memory arrangement (12, 28), and for forming the messages from the control data in a form suitable for a visual display (13) and/or a voice output circuit (14). For providing a more flexible radio receiver, a reading device (16) for reading data of an external first memory arrangement (28), and a second memory arrangement (12) are coupled to the control circuit (7). The first memory arrangement (28) is used for storing control data for region-specific road or area categories and the second memory arrangement (12) is used for storing control data for supra-regional road or area categories which have each a respective class name.
