Abstract

The vehicle radio data system,RDS, and traffic message control, TDC, signal is received Ä1Ü and is passed through the tuner Ä2Ü, stereo decoderÄ4Ü and RDS decoder Ä5Ü to a control circuit Ä7Ü. The low frequency stereo signals are passed to the loudspeakers Ä10,11Ü. Coupled to the controller is a memory Ä12Ü, display Ä13Ü, speech synthesiser Ä14Ü and other items such as a CD-ROM drive. A card reader Ä16Ü allows input from a smart card Ä17Ü. The system memory Ä12Ü stores the traffic specific received data and allows conversion from one foreign language to another depending upon which country the vehicle is in by using the synthesiser. The smart card has a memory section for regional specific data selection control.

The invention relates to a radio receiver with a control circuit

• for the delivery of coded messages derived from a radio signal to at least one memory arrangement,
• for receiving control data derived from the coded messages of at least one memory arrangement and
• to form the messages from the control data in a form suitable for a display device and / or a speech synthesis circuit.

Such a radio receiver is known from the magazine Funkschau 8/92 I Spezial, pages 22 to 26. In this radio receiver, audio signals derived from the received radio signal are processed in an audio circuit. Furthermore, RDS and TMC data are derived from the broadcast signal. RDS is the abbreviation for Radio Data System and TMC for Traffic Message Channel. TMC is a functional extension of RDS. RDS-TMC data are transmitted with the broadcast signal as digitally encoded data. With TMC, the radio listener is given the opportunity, for example, to call up traffic reports stored in the radio as often as required before or after the start of the journey, to listen to traffic reports selected according to the desired route, and to have traffic announcements announced in their own native language regardless of the respective national language. The RDS-TMC data are also generally referred to below as coded messages. It is also conceivable to transmit not only coded traffic reports but also weather reports and other messages with RDS-TMC data or similar coded data. The received coded messages are fed to a memory arrangement, which then gives control data to a control circuit. A storage array contains a database for the formation of traffic messages and can be, for example, a semiconductor memory connected to the control circuit, a semiconductor memory arranged on a chip card, a CD-ROM, etc. From the document mentioned above it is known that the control data are names of a language in spelling and are used for linguistic output. In the following, spelling means the correct spelling of terms in a language. In order to be able to output the names in language, the control circuit can, for example, access a stored digitally coded voice signal stock.

The invention has for its object to provide a radio receiver that enables quick access to the stored control data.

The problem is solved by a radio receiver of the type mentioned at the outset,
that a reading device for reading data from an external, first storage arrangement and a second storage arrangement is coupled to the control circuit and
that the first memory arrangement is provided for storing region-specific control data and the second memory arrangement for storing traffic-specific control data.

The first memory arrangement is part of an external, transportable storage medium, such as a chip card, CD-ROM etc. When using a chip card that contains the first memory arrangement (eg a ROM), region-specific control data are read from the chip card by means of a reading device (card reading device) transmitted to the control circuit. Region-specific tax data are data that are used in a specific region (e.g. place names for the Germany region). Traffic-specific tax data contain names that are used in more than one Region are used and are largely language-related to traffic (e.g. motorway junction, south, train station). Traffic-specific tax data are also to be understood as event-specific tax data. Such event-specific tax data contain, for example, parts of traffic reports without region-specific tax data (eg "10 km traffic jam"). The second memory arrangement is coupled to the control circuit and is used to store the traffic-specific control data. The second memory arrangement can, for example, be a semiconductor memory and can be installed in the RDS-TMC radio receiver. The control data of the second memory arrangement can be accessed faster than the control data of the first memory arrangement. For this purpose, a chip card with the first memory arrangement is easier to replace and can be adapted to new circumstances more easily. Since the first storage arrangement does not contain any traffic-specific data, its storage capacity is also increased.

In order to reduce the amount of data, both memory arrangements are provided for storing specific, different control data, each with a replacement code. After receiving control data containing at least one replacement code, the control circuit is provided for supplying at least one replacement code to the first or second memory arrangement and for receiving the control data stored under the replacement code.

Control data which are assigned to a replacement code are stored in both memory arrangements. Such control data associated with a replacement code includes commonly used terms such as B. "Cologne", "junction" etc. If the control circuit receives a coded message corresponding control data from the first or second memory arrangement, which contain at least one replacement code, only then can the corresponding message (eg traffic message) for a speech synthesis circuit and / or a display device can be formed when the control data stored under a replacement code have been supplied to the control circuit. Because such replacement codes take up less space than that Tax data, the database is therefore reduced. This is particularly advantageous when the radio receiver is used to report traffic and data from a large traffic area (for example Germany) are stored in a memory arrangement. Another advantage of the invention is that a suitable selection of control data stored under a replacement code minimizes possible errors that could arise during the construction of the database and that are visible or audible on the display device and / or the speech synthesis circuit. A suitable selection of control data stored under a replacement code is understood to mean a selection of word sequences, words and word parts (designations) according to linguistic aspects.

It is possible that the control circuit has to access at least one memory arrangement several times to form the message for the display device and / or voice synthesis circuit in order to read control data stored under replacement codes. This can be illustrated using two examples. "12365-Mühlheim" or "78654 43263-Mühlheim" can be used as control data for the designation "Cologne-Mühlheim junction" in a memory arrangement. In the first case, the control circuit reads e.g. the tax data "32987 Cologne" for the replacement code "12365". After that, the control data (here: "connection point") for the replacement code "32987" must be read in order to be able to put the name together. In the second case, the control circuit takes the designations of the connection point ″ and “Cologne” under the replacement codes “78654” and “42263” from at least one memory arrangement.

Control data stored in each of the two memory arrangements is stored under a coded message or a replacement code, from which a description in legal and / or phonetic transcription of at least one first language can be derived. Tax data can receive partial or complete replacement codes that represent a specific name in legal and / or phonetic transcription. Here can also be terms that do not belong to the first language and are borrowed from another language. For example, there is no German name for the Dutch town "Twente". If the German language is the first language, the place "Twente", for example, would be in the Dutch legal text as a legal text of the German language under the corresponding replacement code in at least one memory arrangement.

The data reduction becomes significant when the legal and / or phonetic transcription of several languages are stored in both storage arrangements. In such a case, in addition to the control data of the first language, control data of a further language are only stored in both storage arrangements under a coded message or a replacement code if the legal and / or phonetic transcription of the further language deviate from the first language. This type of storage of control data for other languages enables the amount of data to be reduced even further,

The memory arrangements contain lists assigned to memory areas, each with specific control data assigned to a coded message and a replacement list with the replacement codes and the respectively assigned control data. The first storage arrangement contains a replacement list with region-specific control data and the second storage arrangement contains an additional replacement list with traffic-specific control data.

Furthermore, the first memory arrangement contains a location list for storing location information in legal and / or phonetic transcription of at least one first language, an area list for storing area information in legal and / or phonetic transcription of at least one first language and a section list for storing road sections in legal terms. and / or phonetic transcription of at least one first language. The second storage arrangement is provided for storing event information in legal and / or phonetic transcription of at least one first language. In the list of places are location information (e.g. cities), in the area list there are traffic-technical areas (e.g. Ruhr area). Administrative areas (e.g. Middle Franconia) or tourist areas (e.g. Teutoburg Forest) and the section list contains street sections. The event details or event-specific control data are stored in a standard phrase list of the second memory arrangement. The location, area and section list is region-specific, while the standard phrase list is event-specific.

The first memory arrangement could be part of a chip card, which is provided for inclusion in a card reading device. The structure of such chip cards and their mode of operation is described, for example, in documents US Pat. No. 5,001,753, US Pat. No. 5,146,499, US Pat. No. 5,163,154 and US Pat. No. 5,168,521. The advantage of such chip cards is that, when used in a radio receiver, they are provided for decoding traffic reports for a specific area and are therefore easy to exchange when the location or area changes.

a second embodiment of an RDS-TMC radio receiver with a module coupled to the RDS-TMC radio receiver for processing RDS-TMC data.

1 shows a radio receiver for processing radio signals and for decoding and further processing of RDS-TMC data. RDS means radio data system and provides the radio listener with, for example, traffic reports, data on alternative frequencies of the set station, etc. TMC is the abbreviation for Traffic Message Channel and represents an extension of the functions of RDS. RDS-TMC data that represent coded messages, are transmitted with the broadcast signal as digitally coded data. With TMC, the radio listener is given the opportunity, for example, to call up traffic announcements stored in the radio as often as required before or after the start of the journey, to listen to the traffic announcements selected according to the desired route, and to have the traffic announcements announced in their own mother tongue regardless of the respective national language.

The radio signal received by an antenna 1 of the RDS-TMC radio receiver (FIG. 1) is transmitted via a tuner 2 and an intermediate frequency stage 3 to a stereo decoder 4 and RDS decoder 5. The tuner 2 is controlled by a tuning circuit 6, which is set by a control circuit 7 and an operating arrangement 8 connected to it. The stereo decoder 4 supplies low-frequency stereo signals, which are supplied to two loudspeakers 10 and 11 via an audio amplifier 9. The stereo decoder 4 and the audio amplifier 9 form an audio circuit 69. The RDS decoder 5 takes RDS-TMC data from the low-frequency signal supplied by the intermediate frequency stage 3. The RDS-TMC data and also a clock signal are given from the RDS decoder 5 to the control circuit 7.

A memory 12, a display device 13, a speech synthesis circuit 14 and possibly one or more further arrangements 15, for example a cassette drive, a CD drive, a car telephone etc., are also coupled to the control circuit 7. The memory 12 represents a second memory arrangement. Furthermore, a card reader 16 is connected to the control circuit 7, which exchanges data with a chip card 17 for further processing.

The structure of such a chip card 17 is shown in FIG. 2 as a block diagram. The core element of the chip card 17 is a processor 18, which is coupled to a power supply circuit 19, a clock processing circuit 20 and a bus 21. The power supply circuit 19 is connected to two connections 22 and 23, via which the power supply from the card reading device 16 to the chip card 17 is established. Furthermore, the clock processing circuit 20 receives a clock signal from the card reading device 16 via a connection 24. In the clock processing circuit 20, further clock signals can be derived from the clock signal. Another connection 25 is connected to the processor 18, via which a reset signal can be supplied by the card reading device 16. With the bus 21 is a read-write memory 26 (hereinafter referred to as RAM), a read-only memory 27 (hereinafter referred to as program ROM), a read-only memory 28 (hereinafter referred to as data ROM) and an interface unit 29. Data is exchanged between the card reading device 16 and the chip card 17 via the interface unit 29 and two connections 30 and 31 connected to it. The program ROM 27 contains the program necessary for the operation of the processor 18, the RAM 26 contains data which occur during operation and are changeable and the data ROM 28 contains the TMC data. At least data ROM 28 is part of a first memory array.

The control circuit 7 in FIG. 1 supplies part of the received TMC data, which each represent coded messages, via the card reading device 16 to the chip card 17. From the chip card 17, data derived therefrom are fed back to the control circuit 7 on the basis of this received data converts these with further TMC data derived from the memory 12 into control data for the speech synthesis circuit 14 and / or for the display device 13. After receiving the control data, the speech synthesis circuit 14 transmits synthesized speech via the control circuit 7 to the audio amplifier 9. The control circuit 7 will simultaneously switch the inputs in the audio amplifier 9 such that instead of the stereo signal from the stereo decoder 4, a synthesized speech signal from the speech synthesis circuit 14 via the control circuit 7 and the audio amplifier 9 reaches the speakers 10 and 11. The display device 13 receives control data from the control circuit 7, which represent a message in writing.

The TMC data thus contain coded traffic reports which are decoded with the aid of the chip card 17, the memory 12 and the control circuit 7 and converted into synthesized speech and into a display form for the display device 13. A TMC database 40 (TMCDB) is stored in the data ROM 28, the logical structure of which is explained with reference to FIG. 3 and is stored as a binary file.

The TMC database 40 (TMCDB) contains a directory structure, in the main directory of which, among other things, global data (global data), geographic messages (GMS messages; GMS = Geographic Message Selection) and a data area list (database volume list) are stored.

The global data includes an identification number of the TMC database 40 and coordinate and scaling messages. Different coordinates of a new coordinate system are stored in the TMC database 40 compared to the coordinates of the geodetic coordinate system. The coordinates of the new, saved coordinate system can be converted into the coordinates of the geodetic coordinate system using the scaling messages.

The geographic reports contain data on stations in the relevant regional area. The information about a transmitter includes a frequency determination factor (PI code = program identification code) with which the transmission frequency can be determined and coordinates for the location of the transmitter and its reception area.

With the help of the frequency determination factor (frequency offset), the carrier frequency of the radio signals received by the tuner 2 is matched with RDS-TMC signal components. A carrier frequency is determined, for example, by multiplying the frequency determination factor by the frequency unit 0.1 MHz and adding the start frequency value 87.6 MHz. A frequency determination factor of 0 means, for example, a carrier frequency of 87.6 MHz and 203 means a carrier frequency of 107.9 MHz. This calculation can be carried out in the processor 18 of the chip card 17 or in the control circuit 7 of the radio receiver. Based on the frequency determined, the tuning circuit 6 tunes the tuner 2.

The data area list refers to at least one sub-directory 41 (VOL) in which identification data. Data of a regional database unit 42 (RDB) and a replacement list (escape table) 46 (ESC) are stored. The identification data consists of an EBU code (EBU = European Broadcasting Union) and a coded number (database number). The EBU code designates the state for which messages are stored in the regional database unit 42. The coded number is used to address the regional database unit 42, which contains data for one or more regions in which the chip card 17 is to be used. A region is a certain area that includes parts of a state, a state or even several states in whole or in part.

A regional database unit 42 includes a location list 43 (LOL), an area location list 44 (ALL) and a segment location list 45 (SLL). The lists are each stored in one or more storage areas. The location list 43 contains location information, e.g. Cities, motorway exits, ferry docks, included. The area list 44 indicates traffic-related areas (e.g. Ruhr area), administrative areas (e.g. Middle Franconia) or tourist areas (e.g. Teutoburg Forest). Section list 45 contains street sections.

The escape table 46 (ESC) is also housed in one or more memory areas. The replacement list 46 is used to compress location and area names (region-specific). In this list 46, names and constituent parts of the name are stored, which appear repeatedly in the location list 43, the area list 44 and the section list 45. For example, in addition to the location "Cologne", various parts of the city, such as Cologne-Dellbrück, Cologne-Kalk, Cologne-Porz, etc., are entered in the list of places. In order to reduce the location list, a replacement character is contained in the location list for the location "Cologne", which is precisely specified in the replacement list 46. The replacement list 46 contains a replacement character for a name or part of a name, the one Represents address (eg 2429) in the replacement list 46, and the name to be replaced or the part of the name to be replaced in writing and spelling. The following are examples of entries in a possible replacement list 46: EC RS LS 2209 Passau "pas $ aU 2367 Dortmund "LOCATION $ mUnt 2388 Euskirchen "? OYs" kIR $ C @ n 2418 Oberhausen "?: $ b = 6 $ haU $ z @ n 2429 Cologne "k9ln 2438 Olpe "? Ol $ p @ 2444 Rade "Ra: $ d @ 2509 A1 \ (A1) 2511 A3 \ (A3)

In the above extract from a replacement list 46, for example, the replacement character 2438 represents the place name "Olpe" in spelling and phonetic transcription ("? Ol $ p @). In the 1st column is the replacement code (EC), in the 2nd column a designation a description in phonetic transcription (LS) is stored in the legal text (RS) and in the 3rd column, SAMPA (SAMPA = speech assessment methods phonetic alphabet) is used as the transcription, frequently used name components (eg junction, motorway junction etc.) that are not region-specific but are traffic-specific, can be stored in the memory 12 of the RDS-TMC radio receiver instead of in the replacement list 46 in an additional replacement list in the memory 12. Such a possible additional replacement list could contain the following entries: EC RS LS 0012 western "vEst $ llC $ @ s 0018 Motorway junction "? aU $ to $ ba: n $ kROYts 0019 Junction "? to $ SlUs $ StEl $ @ 0022 Service area "Rast $ StE $ t @

For example, the replacement code 0019 in the additional replacement list above represents the part of the name "Junction" in spelling and phonetic transcription ("? An $ SlUs $ StEl $ @) Column 2 contains a description in spelling (RS) and in the 3rd column a description in phonetic transcription (LS).

The location list 43 contains a location code (for example 3038) and the location name (for example North Rhine-Westphalia, Cologne) for each location in spelling and in phonetic transcription. The location code is a coded message and is used to address the respective location name. The following are five examples from the list of locations: OC RS LS meaning 3038 0018 2438 ○ ○ (Motorway junction Olpe) 3109 Run "running (Run) 3621 0019 Kusel ○ ku: $ z @ l (Kusel junction) 3783 0019 2429-Dellbrück ○ ○ "dEl $ bRYk (Junction Cologne-Dellbrück) 3796 0019 2429-Mühlheim ○ ○ "my: l $ halm (Junction Cologne-Mühlheim)

The above possible list of locations contains the location code (OC) in the first column, the location name in the right column (RS) in the second column or fully or partially in coded form as a replacement code and the third column the location name in Phonetic transcription (LS) or in whole or in part in coded form as a placeholder, each referring to a replacement code in the second column of the list of locations. The fourth column shown above does not exist in the location list and is only intended to show what the individual replacement codes in the location list mean. If, for example, the entry under the location code "3038" is to be read in writing and phonetic transcription from the chip card 17, the control circuit 7 receives the character string "0018 2438" and "○ ○". The characters "0018" and "2438" represent replacement codes in a replacement list. Under the replacement code "0018", for example, "Autobahnkreuz" in the above-mentioned additional replacement list and under the replacement code "2438""Olpe". A placeholder "○" indicates that the corresponding phonetic transcription should be read under the entry "0018" or "2438" of a replacement list. In the control circuit 7 the place name searched for under the address "2438" is then put together in writing (Autobahnkreuz Olpe) and phonetic transcription ("? AU $ to $ ba: n $ kROYts"? Ol $ p @).

The lists described so far contain an entry in legal and phonetic transcription under a location or replacement code. As mentioned above, the entries in legal and phonetic transcription are referred to as tax data. The entry in the legal list in the place list is to be understood in the following as a first main component and the entry in phonetic transcription in the place list as a first secondary component of the tax data. The entry in orthography in the replacement list is understood as a second main component and the entry in phonetic transcription in the replacement list is understood as a second secondary component.

In the area list 44 there is an area code for each area (for example 4803), an area name in writing (for example the western Ruhr area) and an area name in phonetic transcription ("vEst $ llC $ @ s" Ru: 6 $ g @% bi: t) registered. The area code is used to address the respective area names. The following are four examples from a possible area list: BC RS LS meaning 4803 0012 Ruhr area ○ "Ru: 6 $ g @% bi: t (Western Ruhr area) 4991 Bavarian forest '' baI $ RIS $ = 6_ "valt (Bavarian forest 4994 Lake Constance "bo: $ d @ n $ ze: (Lake Constance) 4996 Eifel "? aI $ f @ l (Eifel)

The excerpt from a possible list of areas listed above contains the area code (BC) in the first column, the area name in spelling (RS) in the second column or in whole or in part in coded form as a replacement code, and the area name in phonetic transcription (LS ) or in whole or in part in coded form as a placeholder. The fourth column is not in the area list and is intended to show what the individual replacement codes in the area list mean. For example, the entry "0012 Ruhr area" in the second column (spelling) under the area code 4803 means "Western Ruhr area" because the replacement code "0012" indicates the part of the name "Western". The placeholder (○) refers to the phonetic entry ("vEst $ llC $ @ s) at the address" 0012 ". The entry in orthography in the area list also forms a first main component and the entry in phonetic transcription forms a first secondary component.

The following control processes are carried out in the control circuit 7. If the control circuit 7 has received the coded message "4803", for example, this coded message is supplied as an address or location code to the data ROM 28 on the chip card 17. The entries in legal documents (0012 Ruhrgebiet) and in phonetic transcription (○ "Ru: 6 $ g @% bi: t) are supplied to the control circuit 7 by the chip card 17. The control circuit 7 detects the replacement code (0012) and reads it under this replacement code Registered spelling and phonetic transcription in the memory 12. Here, the control circuit 7 can distinguish, for example, by the first digit, whether it must read from the replacement list in the memory 12 or the replacement list 46 in the data ROM 28. The entry in spelling "Western" is combined with the previously read entry "Ruhr area". The phonetic entries are handled in a similar manner. If only the phonetic spelling is to be put together and given to the speech synthesis circuit 14, the procedure is as follows. The control circuit recognizes the placeholder "○" in the phonetic transcription (○ "Ru: 6 $ g @% bi: t) and therefore reads the corresponding replacement code (0012) in the area list and then reads the entry stored under this replacement code the phonetic transcription in the replacement list of the memory 12. The phonetic transcriptions are then combined, as already explained above.

The section list 45 each contains street sections in spelling and phonetic transcription and a section code which corresponds to a coded message and is provided for addressing the section of street concerned. Three examples from a possible section list are listed below: AC RS1 LS1 RS2 LS2 RS3 LS3 meaning 5024 2511 ○ 2429 ○ 2418 ○ (A3, Cologne, Oberhausen) 5108 2509 ○ 2367 ○ 2388 ○ (A1, Dortmund, Euskirchen) 5130 2511 ○ 2209 ○ Linz "Left (A3, Passau, Linz)

The section code (AC) is entered in the first column of the section list 45. The second column contains the street name in spelling (RS1) or a replacement code that refers to the street name in spelling in the replacement list 46 (eg 2511). In the third column, the street name or a placeholder is entered in phonetic transcription (LS1), which specifies the corresponding entry of the street name in phonetic transcription in the replacement list. The nodes of the road sections, which respectively represent the beginning and end of the relevant road section, are in writing (e.g. Linz) or in whole or in part in coded form as a replacement code (e.g. 2209) in the fourth and sixth column (RS2, RS3) is shown. The fifth and seventh columns list the nodes in phonetic transcription or in whole or in part in coded form as placeholders (LS2, LS3). The seventh column is not part of the section list, but serves to understand what the individual replacement codes mean (e.g. A3 motorway, Passau and Linz junctions). This section list contains a total of three first main components (RS1, RS2, RS3) and three first secondary components (LS1, LS2, LS3) of the control data specified under a section code.

The location, area and section lists can also optionally contain further columns in order to provide the respective user of the RDS-TMC radio receiver with further messages for specific entries in lists 43 to 46. The location code, area code and section code are, as already mentioned above, special names for each coded information.

In order to form a complete message in the RDS-TMC radio receiver which can be processed by the speech synthesis circuit 14 or the display device 13, a further list of standard phrases is stored in the memory 12. The memory 12 thus contains event-specific control data (in a standard phrase list) and traffic-specific control data (additional replacement list). With such a standard phrase list, the following messages could be generated in writing in the control circuit 7: 1 In the Teutoburg Forest area: fog 2nd In the Dresden city area: sporting event. 3rd A2, Dortmund direction Hannover, between Rehren and Lauenau: 4 km traffic jam. 4th A4 Kölner Ring, Aachen direction Olpe, Autobahnkreuz Köln-Ost: exit blocked. 5 A3, Cologne Oberhausen, between the Cologne-Dellbrück junction and the Cologne-Mühlheim junction: slow-moving traffic

Message No. 5 could have been received by the RDS-TMC radio receiver in the following coded form, for example:
P1 {5024, 3783, 3796}, P2

The message consists of two standard phrases P1 and P2. In the standard phrase P1, the designations or name components stored under the codes (addresses or arguments of P1) "5024", "3783" and "3796" must be read by the chip card 17. For example, the code "5024" can be found in the section list. "A3, Cologne, Oberhausen" is entered under the section code "5024". The other two arguments or codes of P1 can be found, for example, in a location list. "Köln-Dellbrück" is entered under the location code "3783" and "Köln-Mühlheim" is entered under the location code "3796". If, instead of the codes, the corresponding designations are entered in the standard phrase P1, the following results:
P1 {(A3, Cologne, Oberhausen), Cologne-Dellbrück junction, KölnMühlheim junction} + P2

The exact wording for the standard phrase P1 or P2 is taken from the standard phrase list and reads:
P1 = 〈street number〉, 〈node〉 direction 〈node〉, between 〈locationname〉 and 〈locationname〉:
P2 = slow-moving traffic

In the angle brackets there are variables that have to be replaced by the names given above (e.g. A3).

The measures carried out in the control circuit 7 for the composition of a message to be displayed on the display device 13 are also carried out in a similar manner for the compilation of the phonetic transcription which is delivered to the speech synthesis circuit 14.

The RDS-TMC Rundfurkempänger shown above and the chip card 17 are suitable for a user to whom the traffic news in German is communicated by means of the display device 13 and / or the speech synthesis circuit 14. Such an RDS-TMC radio receiver and also the chip card 17 can also be set up for other languages. In this case, the corresponding spelling and / or phonetic transcription of this language can be stored in the memory 12 and in the data ROM 28 of the chip card 17.

There is also the possibility of using the RDS-TMC radio receiver and the chip card 17 for several languages. However, in order to keep the effort low, a radio receiver should be set up for a specific language (language-specific). Therefore, only one legal and / or phonetic transcription for one language (eg German) is stored in the memory 12. In contrast, a chip card 17 is set up regionally. Region-specific data of several languages are stored in their data ROM 28. For example, if the Languages German, English, French and Dutch should be usable, so the lists stored in the data ROM 28 of the chip card 17 are expanded. For example, the replacement list 46 contains the following entry under the replacement code "2429": EC RSd LSd LSe LSf LSn 2429 Cologne "k9ln ¶ $ k @ "l @ Un (Cologne) ¶ $ ko "lOj (Cologne) ¶ "kui $ l @ n (clubs)

For the location "Cologne" in the substitution list 46 under the replacement code (EC) "2429" are the German spelling (RSd) and phonetic transcription (LSd) and the English (LSe), the French (LSf) and the Dutch phonetic transcription (LSn) available. If necessary, entries for the spelling of the non-German languages can also be saved. The legal texts of the non-German languages are listed in brackets below the respective phonetic transcription. The phonetic transcriptions of the non-German languages represent further first secondary components of the tax data, which are stored under the replacement code "2429". For the non-German languages, a first separator (¶) is placed before each phonetic spelling. These first separators indicate that the non-German languages are entered in the list in a predetermined order (standard order). The order of the list entries for the different languages is therefore fixed. A standard order also exists if languages have been left out at the end of the order (e.g. Dutch).

If there is no deviation from the German phonetic spelling in another language for a certain name, there is no corresponding entry in the list. For example, suppose that the phonetic spelling for the location "Cologne" in the French language is identical to the phonetic spelling for the German language. In this case there is no entry for the in the replacement list 46 French language included. The respective non-German languages must then be marked in the list for the location "Cologne". For the identification of the English phonetic transcription, a second separator "‡" is added with another language-specific character (s) before the phonetic transcription. In the Dutch language "‡ n" is used. The second separator "‡" is therefore supplemented by the language-specific character "n". The entry for the place "Cologne" would have the following appearance in this assumed case: EC RSd LSd LSe LSn 2429 Cologne "k9ln ‡ e $ k @ "l @ Un ‡ n "kui $ l @ n

In the exemplary location list 43 given above, the location “Lauf” is listed under the location code “3109”. There is no English, French or corresponding Dutch legal and phonetic transcription for this place. If a name (e.g. the place "Lauf") is written and pronounced in the English, French and Dutch languages as in the German language, there is no further entry in the legal and phonetic spelling.

In the case of a combination of at least one designation with different phonetic transcriptions and at least one designation with the same phonetic transcription in the different languages, the designation with different phonetic transcription is entered in the replacement list 46 and the corresponding table contains the replacement code for this designation. For example, the place "Köln-Mühlheim" was entered in the place list 43 under the place code "3886". For "Cologne", the place code 43 refers to the replacement code "2429". The term "Mühlheim" is pronounced the same in all the languages listed. The corresponding entry in a list of places 43 thus has the following appearance: 3886 2429-Mühlheim ○ "my: l $ halm

For the designation "Cologne", no entry in the list of places 43 is necessary for the non-German languages, despite different phonetic transcriptions, since these are already present in the replacement list 46.

〈Straßennummer〉, 〈Ortsname〉, 10 Kilometer Stau

existiert ein entsprechender französischer Eintrag:
   

Sur l'autoroute 〈Straßenname〉 à la hauteur de 〈Ortsname〉, bouchon sur 10 kilometres

.Thus, the location list 43, the area list 44, the section list 45 and the replacement list 46 each contain non-German phonetic transcriptions if these differ from the German language. The standard phrase list also contains entries in English, French and Dutch, for example. For the German standard phrase

〈Street number〉, 〈Location name〉, 10 kilometers traffic jam

there is a corresponding French entry:

Sur l'autoroute 〈street name〉 à la hauteur de 〈place name〉, bouchon sur 10 kilometers

.

A4") und der entsprechende Ortsname (z.B.

Köln

) eingesetzt werden.For the street name and place name, the corresponding street name (e.g.

A4 ") and the corresponding place name (e.g.

Cologne

) are used.

When this message is composed in the control circuit 7, the corresponding control data are first taken from the standard phrase list. If only French entries are stored in the memory 12 (radio receivers for the French language), the control data only contain entries for the French language and no selection in the control data has to be carried out. However, the memory 12 contains entries for the French and German language and if the German language is set as the first language, after receiving the control data from the standard phrase list, a selection is made, for example, of the French phonetic entry.

Then the French phonetic entries for the street name "A4" and the place "Cologne" are searched. For the location "Cologne", it is necessary to first go to the location list in which tax data is entered under a corresponding location code (coded message). If the location list contains entries for the German language (as the first language) and can contain entries for the English, French and Dutch language, the corresponding French entry is searched for in control circuit 7 after receipt of the tax data from the location list. This does not exist because only one replacement code is entered in the first main component of the German language (German legal text). The German phonetic spelling can be omitted or have a placeholder. The control circuit 7 then takes the control data of the corresponding replacement code from the replacement list 46, which is stored in the data ROM 28 of the chip card 17. The French phonetic entry for the location "Cologne" is taken from the received tax data and inserted into the standard phrase. The same process is carried out by the control circuit 7 when the French phonetic entry for the street name "A4" is removed.

4 shows a further radio receiver, which is coupled to an RDS-TMC module 47 via different lines. The radio receiver contains an audio circuit 48 with a stereo decoder 49 and an audio amplifier 50 and two loudspeakers 51 and 52. The audio circuit 48 receives a radio signal received by an antenna 53 and passed on via a tuner 54 and an intermediate frequency stage 55. A low-frequency stereo signal is formed in the stereo decoder 49 and is supplied to the two loudspeakers 51 and 52 via the audio amplifier 50. The output signal of the intermediate frequency stage 55 is also supplied to an RDS decoder 56 and the RDS-TMC module 47. The RDS decoder 56 takes RDS data from the low-frequency signal supplied by the intermediate frequency stage 55. The RDS data and also a clock signal are sent from the RDS decoder 56 to a radio control circuit 57. The tuner 54 is set by means of the RDS data and data supplied by an operating arrangement 59. To this end, the radio control circuit 57 supplies the corresponding data to a tuning circuit 58 controlling the tuner 54.

A memory 60, a display device 61 and possibly one or more further arrangements 62, for example a cassette drive, a CD drive, a car telephone, etc., are also coupled to the radio control circuit 57. Furthermore, the radio control circuit 57 is coupled to the RDS-TMC module 47, which contains an RDS decoder 63, a control circuit 64, a speech synthesis circuit 65, a card reading device 66 for receiving a chip card 67 and a memory 68, via a plurality of lines. The RDS decoder 63 supplies the RDS and TMC data taken from the output signal of the intermediate frequency stage 55 and a clock signal to the control circuit 64. The control circuit 64, which processes RDS-TMC data like the control circuit 7 from FIG. 1; provides TMC data to the card reading device 66 and forms control data from the data received from the card reading device 66 and further data from the memory 68 (data in spelling and spelling), which is supplied to the speech synthesis circuit 65. The speech synthesis circuit 65 generates speech synthesized from the control data, which speech is supplied to the audio amplifier 50 via the radio control circuit 57. Furthermore, the control circuit 64 optionally forms a traffic report in writing from the control data, which is fed to the display device 61 via the radio control circuit 57.
