Memory structure for use in a broadcast receiver, particularly for providing traffic or geographic information
First Claim
1. A broadcast receiver, comprising a control circuit (7) fordelivering encoded messages, derived from a broadcast signal, to at least one storage device (12, 28),receiving control data, derived from the encoded messages, from at least one storage device (12, 28), andforming the messages from the control data in a form which is suitable for a display device (13) and/or a speech synthesizer circuit (14), characterized in thata reading device (16) for reading data from an external, first storage device (28) and a second storage device (12) are coupled to the control circuit (17), and that the first storage device (28) is intended for the storage of region-specific control data and the second storage device (12) for the storage of traffic-specific control data.

Abstract
The invention relates to a broadcast receiver, comprising a control circuit (7) for applying encoded messages, derived from a broadcast signal, to at least one storage device (12, 28), for receiving control data, derived from the encoded messages, from at least one storage device (12, 28), and for forming the messages from the control data in a form suitable for a display device (13) and/or a speech synthesizer circuit (14). In order to accelerate access to the control data, a reading device (16) for reading data from an external first storage device (28) and a second storage device (12) are coupled to the control circuit (7). Moreover, the first storage device (28) is intended to store region-specific control data and the second storage device (12) is intended to store traffic-specific control data.

18. A module (47) for the processing of encoded messages derived from a broadcast signal, comprising a control circuit (64) which is arranged to
deliver encoded messages, derived from the broadcast signal, to at least one storage device (68, 28), receive control data, derived from the encoded messages, from at least one storage device (689, 28), and form the messages from the control data in a form suitable for a display device (13) and/or a speech synthesizer circuit (14), characterized in that a reading device (66), arranged to receive an external, first storage device (28) for the storage of region-specific control data, and a second control device (68) for the storage of traffic-specific control data are coupled to the control circuit (64).

19. A broadcast receiver comprising
means for receiving an encoded broadcast message; -
a first storage device (12) for storing frequently used natural language word information, the phrase "natural language word information" being abbreviated herein as "words"; a second storage device (28) for storing less frequently used words; a control circuit for, responsive an encoded message, combining less frequently used words from the second storage device with more frequently used words from the first storage device to form a decoded message; and output means for providing the decoded message to a user. - View Dependent Claims (20, 21, 22, 23, 24)

- 25. A chip card for insertion into a card reader of a broadcast receiver, the chip card comprising a computer readable medium embodying a data structure storing region specific portions of geographical place names in such a way as to be accessible by at least a part of an encoded message, the portions being suitable for combination with other portions of the geographical place names which are not region specific, the other portions not being stored in the chip card, the portions and other portions together forming a decoded message.
