  • Receiver for RDS-TMC broadcast messages including storage device for storing control data under a code
    Patent number: 6173165
    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 reduce the data file, given control data is stored under a respective escape code in at least one storage device (12, 28). The control data contains, for example phonetic notations of different languages. After reception of control data containing at least one escape code, the control circuit (7) applies said escape codes to a storage device (12, 28) for further processing of the control data stored under the escape code.
