Description

The invention relates to a radio receiver according to the preamble of Claim 1.

Such a radio receiver is from the magazine Funkschau 8/92 I Spezial, pages 22 known until 26. In this radio receiver are received from the Broadcast signal derived audio signals processed in an audio circuit. Further RDS and TMC data are derived from the broadcast signal. RDS is the Abbreviation for Radio Data System and TMC for Traffic Message Channel (traffic news channel). TMC is a functional extension of RDS RDS-TMC data with the broadcast signal as digitally encoded data transfer. With TMC, for example, the radio handset is given the opportunity to Traffic reports stored in the radio as often as desired before or after Calling up the start of the journey, traffic reports selected according to the desired route eavesdropping and traffic reports regardless of the respective national language in the have your own native language announced. The RDS-TMC data are as follows also commonly referred to as coded messages. It is also conceivable, not just coded Traffic reports but also weather reports and other messages with RDS-TMC data or similar coded data to transmit. The received encoded Messages are fed to a memory arrangement, which then sends control data to a Control circuit there. A memory arrangement contains a database for formation of traffic news and can, for example, be connected to the control circuit Semiconductor memory, a semiconductor memory arranged on a chip card, a CD-ROM etc. From the above document it is known that the tax data Descriptions of a language are in spelling and are used for language output. Below is the correct spelling of terms understand a language. In order to be able to output the names verbally, the control circuit e.g. to a stored digitally coded speech signal stock To fall back on.

EP 0 725 505 A1 and EP 0 725 501 A1 each also have a radio receiver for the reception and playback of digitally coded traffic reports Contain location information and event information known. Received digitally coded Traffic reports are a device for decoding the traffic reports can be supplied, location-related information required for decoding the traffic reports Data is stored on a removable medium. From the decoded Traffic reports can be derived from playback data, with the deriving of the Playback data required additional location-related data on the interchangeable Data carriers are stored. The playback data is a playback device fed. The removable disk may or may not be a read-only memory volatile rewritable memory containing the location-related data are filed. A location list contained in a location-related data includes location names also contain, for example, identifiers which represent a coded designation. The designations assigned to an identifier are contained in a table. Data reduction can be achieved with this. It is also located in the Broadcasters still have an event set list with event codes for specific ones Events. A code 101 can denote the event of a traffic jam, for example.

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

The task is performed according to a radio receiver of the type mentioned solved the characterizing part of claim 1.

The first storage arrangement is part of an external, transportable Storage medium, e.g. Chip card, CD-ROM etc. When using a chip card, which contains the first memory arrangement (e.g. a ROM) become region-specific Control data from the chip card by means of a reading device (card reading device) read and transferred to the control circuit. Regional tax data are such Data in a specific region (e.g. place names for the Germany region) be used. Traffic-specific tax data contain terms that are used in more as one Region are used and largely language-related to traffic are (e.g. Autobahnkreuz, Süd, Bahnhof). Under traffic-specific tax data event-specific tax data are also to be understood. Such event-specific For example, tax data contains parts of traffic reports without Region-specific tax data (e.g. "10 km traffic jam"). The second storage arrangement is coupled to the control circuit and is used to store the traffic-specific tax data. The second memory arrangement can, for example be a semiconductor memory and 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 can be accessed. For that is one Chip card with the first memory arrangement can be exchanged more easily and can be new Conditions can be adapted more easily. Since the first storage arrangement does not contains traffic-specific data, their storage capacity is also increased.

To reduce the amount of data, both storage arrangements are available Storage of certain, different tax data under one Replacement code provided. The control circuit is after receiving control data, which contain at least one replacement code for feeding at least one Replacement codes to the first or second memory arrangement and for receiving the tax data stored under the replacement code.

Control data are stored in both memory arrangements, which have a replacement code assigned. Contain control data associated with such a replacement code frequently used terms, such as "Cologne", "junction" etc. Receives the control circuit for a coded message corresponding control data from the first or second memory arrangement, the at least one replacement code only then can the corresponding message (e.g. traffic message) are formed for a speech synthesis circuit and / or a display device, if the control data of the control circuit stored under a replacement code have been supplied. Because such replacement codes take up less space than that Tax data, the database is therefore reduced. This is particularly advantageous if the radio receiver for traffic announcement is used and data from a large traffic area (e.g. Germany) in one Storage arrangement are stored. Another advantage of the invention is that by suitable selection of tax data stored under a replacement code Minimization of possible errors that arise when building up the database could and on the display device and / or the speech synthesis circuit visible or audible is guaranteed. Under a suitable selection of A tax code is saved under a replacement code Word sequences, words and parts of words (designations) according to linguistic Point of view understood.

It is possible that the control circuit multiple times to form the message for the Display device and / or voice synthesis circuit on at least one Memory array must access to be stored under replacement codes Read tax data. This can be illustrated using two examples. For the Designation "Junction Cologne-Mühlheim" can be in a storage arrangement "12365-Mühlheim" or "78654 43263-Mühlheim" as tax data. By doing in the first case the control circuit reads e.g. the tax data "32987 Cologne" for the Replacement code "12365". Then the tax data (here: "Junction") for the replacement code "32987" can be read around the To be able to put together a description. In the second case, the Control circuit the names "Junction" and "Cologne" under the Replacement codes "78654" and "42263" from at least one memory array.

In both storage arrangements are each under a coded message or a control code stored control data, from which one Name in legal and / or phonetic transcription of at least one first language can be derived. Tax data may receive partial or full replacement codes that represent a certain name in legal and / or phonetic transcription. in this connection can also be terms that do not belong to the first language and borrowed another language. For example, for Dutch place "Twente" no German name. If the German Language is the first language, for example, would be in the Dutch Spelling the place "Twente" as a spelling 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 multiple languages are stored in both memory arrangements. In one Except for the control data of the first language, only then is control data one further language in both memory arrangements, each coded under one Filed message or a replacement code if the legal and / or phonetic transcription the other language deviate from the first language. Through this type of Saving control data of other languages can further increase the amount of data be reduced

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

Furthermore, the first storage arrangement contains a location list for storing Locations in legal and / or phonetic transcription of at least one first language, one Area list for storing area information in legal and / or phonetic transcription at least a first language and a section list for storing Road sections in legal and / or phonetic transcription of at least one first language. The second storage arrangement is for storing event information in legal and / or phonetic transcription of at least one first language is provided. In the list of places are location information (e.g. cities), in the area list are traffic engineering Areas (e.g. Ruhr area), administrative areas (e.g. Middle Franconia) or tourist areas (e.g. Teutoburg Forest) and in the section list Road sections included. The event details or event-specific Control data is in a standard phrase list of the second memory arrangement accommodated. 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 that is used for Recording in a card reader is provided. The structure of such Chip cards and how they work is described, for example, in the documents U.S. 5,001,753, U.S. 5,146,499, U.S. 5,163,154 and U.S. 5,168,521. The The advantage of such chip cards is that they are used in a radio receiver for decoding traffic reports for a specific area are provided and thus easily in the event of a change of location or area are to be exchanged.

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

In Fig. 1 is a radio receiver for processing radio signals and for Decoding and further processing of RDS-TMC data shown. RDS means Radio data system and provides the radio handset with traffic reports, for example, Data about alternative frequencies of the tuned station, etc. TMC is the abbreviation for Traffic Message Channel and represents a functional extension of RDS. RDS-TMC data, which represent coded messages are with the broadcast signal as transmit digitally coded data. With TMC, for example, the radio receiver Possibility given traffic reports stored in the radio as often as desired to call up before or after departure, the traffic reports selected after the listen to the desired route and the traffic reports regardless of have the respective national language announced in their own mother tongue.

That received by an antenna 1 of the RDS-TMC radio receiver (Fig. 1) Broadcast signal is via a tuner 2 and an intermediate frequency stage 3 a stereo decoder 4 and RDS decoder 5 transmitted. The tuner 2 is one Tuning circuit 6 controlled by a control circuit 7 and one thereon connected operating instructions 8 is set. The stereo decoder 4 provides low-frequency stereo signals, the two via an audio amplifier 9 Speakers 10 and 11 are supplied. The stereo decoder 4 and Audio amplifiers 9 form an audio circuit 69. The RDS decoder 5 takes out the low-frequency signal RDS-TMC data supplied by the intermediate frequency stage 3. The RDS-TMC data and also a clock signal are from the RDS decoder 5 given to the control circuit 7.

The control circuit 7 also includes a memory 12, a display device 13, a speech synthesis circuit 14 and optionally one or more others Arrangements 15, for example a cassette drive, a CD drive, a car phone etc., coupled. The memory 12 represents a second memory arrangement. Furthermore, a card reading device 16 is connected to the control circuit 7 connected, exchanges the 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 shown. The core element of the chip card 17 is a processor 18 which is connected to a Power supply circuit 19, a clock processing circuit 20 and one Bus 21 is coupled. The power supply circuit 19 has two connections 22 and 23 connected via which the power supply from the card reader 16 to the chip card 17 is produced. The clock processing circuit also receives 20 via a connection 24 a clock signal from the Card reader 16. In the clock processing circuit 20 can from the Clock signal further clock signals are derived. With the processor 18 is a further connection 25 connected via which a reset signal from the card reader 16 can be delivered. With the bus 21 is a read-write memory 26 (hereinafter referred to as RAM), a read-only memory 27 (im hereinafter referred to as program ROM), a read-only memory 28 (hereinafter referred to as data ROM) and an interface unit 29 coupled. About the Interface unit 29 and two connections 30 and 31 connected to it data between the card reader 16 and the smart card 17th replaced. The program ROM 27 contains this for the operation of the processor 18 required program, the RAM 26 contains data during operation occur 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 reader 16 Chip card 17. The chip card 17 is based on this received data data derived therefrom led back to the control circuit 7, which this with further TMC data derived from the memory 12 in control data for the Speech synthesis circuit 14 and / or implemented for the display device 13. The Speech synthesis circuit 14 outputs synthesized after receiving the control data 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 so that instead of 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 to the speakers 10 and 11. The display device 13 receives from the Control circuit 7 control data representing a message in writing.

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

The TMC database 40 (TMCDB) contains a directory structure in which Main directory including global data, geographic Messages (GMS messages; GMS = Geographic Message Selection) and one 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. There are 40 in the TMC database different from the coordinates of the geodetic coordinate system Coordinates of a new coordinate system filed. By means of the scaling messages can save the coordinates of the new, saved coordinate system in the coordinates of the geodetic coordinate system are converted.

The geographic reports contain data about the station of the concerned regional area. A frequency determination factor is part of the information about a transmitter (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 tuner 2 with RDS-TMC signal components Voted. A carrier frequency is determined by, for example Multiplication of the frequency determination factor by the frequency unit 0.1 MHz and addition of the starting frequency value 87.6 Mhz determined. A frequency determination factor 0 means, for example, a carrier frequency of 87.6 MHz and of 203 has a carrier frequency of 107.9 MHz. This calculation can be done in the processor 18 of the chip card 17 or in the control circuit 7 of the radio receiver become. The tuning circuit 6 is correct on the basis of the frequency determined the tuner 2.

The data area list refers to at least one subdirectory 41 (VOL), in the identification data. Data from a regional database unit 42 (RDB) and an escape table 46 (ESC) is stored. The identification data consist 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, the Contains data for one or more regions in which the chip card 17 for Application should come. A region is a specific area that is part of a State, a state or several states in whole or in part.

A regional database unit 42 contains a location list 43 (LOL), an area location list 44 (ALL) and a section list (segment location list) 45 (SLL). The lists are each in one or more memory areas accommodated. The location list 43 contains location information, e.g. cities, Motorway exits, ferry docks, included. The area list 44 gives traffic engineering Areas (e.g. Ruhr area), administrative areas (e.g. Middle Franconia) or tourist areas (e.g. Teutoburg Forest). In section list 45 sections of road are included.

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 description or a name component, which represents an address (for example 2429) in the replacement list 46, and the name or the name component 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 "There $ Munt 2388 Euskirchen n "oys?" Kir $ C @ 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 Interchange "AU $ to $ ba? N $ kROYts 0019 junction "? $ To $ SLUs STEL $ @ 0022 Service Area "Rest $ StE $ t @

For example, the replacement code represents 0019 in the one listed above additional replacement list the name component "connection point" in spelling and phonetic transcription ("? an $ SlUs $ StEl $ @). This section of a replacement list shows in in the 1st column a replacement code (EC), in the 2nd column a name in Spelling (RS) and in the 3rd column a name in phonetic transcription (LS).

The location list 43 contains a location code (e.g. 3038) and the location name (e.g. North Rhine-Westphalia, Cologne) for each location in spelling and 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 importance 3038 0018 2438 ○ ○ (Motorway junction Olpe) 3109 run "run (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 location list contains the location code (OC) in the first column second column the place name in spelling (RS) or in whole or in part in coded form as a replacement code and the third column the place name in Phonetic transcription (LS) or in whole or in part in coded form as a placeholder, the refers to a replacement code in the second column of the list of locations. The 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. For example, if Entry under the location code "3038" in spelling and phonetic transcription from the Chip card 17 are read, the control circuit 7 receives the string "0018 2438" and "○ ○". The characters "0018" and "2438" represent replacement codes in a replacement list. For example, under the replacement code "0018" "Autobahnkreuz" in the above replacement list and under the Replacement code "2438" should be "Olpe". A placeholder "○" indicates that the corresponding phonetic transcription under the entry "0018" or "2438" of a replacement list should be read. In the control circuit 7 is then the address "2438" searched for place name in spelling (Autobahnkreuz Olpe) and phonetic transcription ("? aU $ to $ ba: n $ kROYts"? Ol $ p @).

The lists described so far contain a location or replacement code an entry in legal and phonetic transcription. The entries in legal and phonetic transcription are referred to as control data, as mentioned above. The entry in spelling in the list of locations should appear in the following as a first main component and the entry in Phonetic transcription in the list of places as a first secondary component of the tax data be understood. As a second main component, the entry in Spelling in the replacement list and as a second secondary component of the entry understood in phonetic transcription in the replacement list.

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) entered. The area code is used to address the respective area names. The following are four examples from a possible area list: BC RS LS importance 4803 0012 Ruhr area ○ "Ru: 6 $ g @% bi: t (Western Ruhr area) 4991 Bavarian forest BAI $ RIS = $ valt 6_ ''' (Bavarian forest 4994 Lake Constance "Bo: $ d @ n $ ze: (Lake Constance) 4996 Eifel "? AI $ f @ l (Eifel)

The section from a possible list of areas listed above contains in the the first column the area code (BC), in the second column the area name in Spelling (RS) or in whole or in part in coded form as a replacement code and in the third column 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 exists and is intended to show what the individual replacement codes in the area list mean. For example, the entry "0012 Ruhr area" means in the second Column (legal text) under area code 4803 "Western Ruhr Area", since the Replacement code "0012" indicates the part of the name "Western". The placeholder (o) refers to the phonetic entry ("vEst $ llC $ @ s) at the address" 0012 ". The entry in spelling in the area list also forms a first Main component and the entry in phonetic transcription 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. The control circuit 7 can use the first digit to distinguish, for example, 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 the writing "Western" is combined with the previously read entry "Ruhrgebiet". The entries in phonetic transcription are processed in a similar manner. If only the phonetic transcription is to be put together and added to the speech synthesis circuit 14, the following is carried out. 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. Then it reads the entry of the phonetic transcription stored in this replacement code in the replacement list of the memory 12. Then, as already explained above, the phonetic transcriptions are combined.

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 relevant street section. Three examples from a possible section list are listed below: AC RS1 LS1 RS2 LS2 RS3 LS3 importance 5024 2511 ○ 2429 ○ 2418 ○ (A3, Cologne, Oberhausen) 5108 2509 ○ 2367 ○ 2388 ○ (A1, Dortmund, Euskirchen) 5130 2511 ○ 2209 ○ Linz "lint (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 one Replacement code that appears on the street name in spelling in the Replacement list 46 (e.g. 2511) references. In the third column is in phonetic transcription (LS1) the street name or a placeholder entered the corresponding one Specifies the street name in phonetic transcription in the replacement list. The Nodes of the road sections, the beginning and end of the respective Street section represent, are in writing (e.g. Linz) or in full or partly in coded form as a replacement code (e.g. 2209) in the fourth and sixth column (RS2, RS3) is shown. In the fifth and seventh columns are Nodes in phonetic transcription or in whole or in part in coded form as Placeholders listed (LS2, LS3). The seventh column is not part of the Section list, but is used to understand what each replacement code is mean (e.g. A3 motorway, Passau and Linz junctions). In this Section list is a total of three first main components (RS1, RS2, RS3) and three first secondary components (LS1, LS2, LS3) each under one Tax code specified in the section code.

The location, area and section lists may also contain other columns included to the respective for certain entries in lists 43 to 46 Users of the RDS-TMC radio receiver to deliver further messages. The As already mentioned, the location code, area code and section code are special Names for one coded information each.

In order to form a complete message in the RDS-TMC radio receiver that 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 2 In the Dresden city area: sporting event. 3 A2, Dortmund direction Hannover, between Rehren and Lauenau: 4 km traffic jam. 4 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

The message No. 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), junction Cologne-Dellbrück, junction Cologne-Mühlheim} + P2

P1 = < Straßennummer >, < Knotenpunkt > Richtung < Knotenpunkt >, zwischen < Ortsname > und < Ortsname > :

P2 = zähfließender Verkehr

The exact wording for the standard phrase P1 or P2 is taken from the standard phrase list and reads:

P1 = <street number>, <junction> direction <junction>, between <place name> and <place name>:

P2 = slow-moving traffic

In the angle brackets there are variables that are identified by the names given above must be replaced in writing (e.g. A3).

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

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

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. If, for example, the languages German, English, French and Dutch should be usable, 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" is in the replacement list 46 under the replacement code (EC) "2429" the German legal (RSd) and phonetic transcription (LSd) and the English (LSe), French (LSf) and Dutch phonetic transcriptions (LSn) available. If necessary, entries for the spelling of the non-German can also Languages can be saved. The legal texts of the non-German languages are in Parentheses are listed below the respective phonetic transcription. The phonetic transcriptions of the non-German languages represent further first secondary components of the Tax data that are stored under the replacement code "2429". For the non-German languages is also a first before each phonetic spelling Separator (¶) set. These first separators indicate that in a given order (standard order) the non-German languages in the List are entered. The order of the list entries for the different So languages are fixed. A default order is also when 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, the replacement list 46 does not contain an entry for the French language. 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 "run" is below the Location code "3109" listed. There is neither an English nor an English for this place French still a corresponding Dutch legal and phonetic transcription. If in English, French and Dutch Name (e.g. the place "Lauf") as written in German and is pronounced is also no further entry in the legal and phonetic transcription available.

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 substitution list 46 and the corresponding table contains the substitution 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-Muelheim ○ "my: l $ halm In spite of the different phonetic spelling, no entry in the list of places 43 is necessary for the designation "Cologne" for the non-German languages, since these are already available in the replacement list 46.

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>, <place 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".

For the street name and place name, the corresponding must still be in the control circuit 7 Street name (e.g. "A4") and the corresponding place name (e.g. "Cologne") can be used.

When composing this message in the control circuit 7 will be first the corresponding tax data is taken from the standard phrase list. If only French entries are stored in the memory 12 (radio receiver for the French language), the tax data only contain entries for the French language and there is no selection in the tax data be performed. However, the memory 12 contains entries for the French and German language and the German language is set as the first language After receiving the control data from the standard phrase list, a selection e.g. of the French phonetic entry.

After that, the French phonetic entries for the street name "A4" and the place "Cologne" wanted. For the location "Cologne" it is necessary first go to the location list, in the under a corresponding location code (coded message) tax data are entered. If the place list has entries for the German language (as the first language) and contains entries for the English, French and Dutch language may be available upon receipt of the Control data from the list of locations in the control circuit 7 of the corresponding French Wanted entry. This does not exist because the first main component of the German language (German law) only a replacement code is entered. The German phonetic spelling can be omitted or have a placeholder. The control circuit 7 then takes from the replacement list 46, which in the Data ROM 28 of the chip card 17 is stored, the control data of the corresponding Replacement codes. The French tax data is converted from the received tax data Phonetic entry for the place "Cologne" taken and in the standard phrase inserted. The same process takes place when the French is removed Phonetic entry for the street name "A4" from the control circuit 7 carried out.

4 shows a further radio receiver, which is equipped with an RDS-TMC module 47 is coupled via different lines. The radio receiver contains an audio circuit 48 with a stereo decoder 49 and an audio amplifier 50 and two speakers 51 and 52. The audio circuit 48 receives one of an antenna 53 received and via a tuner 54 and an intermediate frequency stage 55 passed broadcast signal. In the stereo decoder 49 is a low frequency Stereo signal formed, the audio speakers 50 the two speakers 51 and 52 is supplied. 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 from that of the intermediate frequency stage 55 supplied low-frequency signal RDS data. The RDS data and further a Clock signals are sent from the RDS decoder 56 to a radio control circuit 57 given. By means of the RDS data and data from an operating order 59 are delivered, the tuner 54 is set. For this purpose, the tuner 54 controlling tuning circuit 58 from the radio control circuit 57 the corresponding data supplied.

With the radio control circuit 57 are still a memory 60, a display device 61 and optionally one or more further arrangements 62, for example a cassette drive, a CD drive, a car phone, etc., coupled. Furthermore, the radio control circuit 57 is connected via several lines coupled to the RDS-TMC module 47, which an RDS decoder 63, a Control circuit 64, a speech synthesis circuit 65, a card reader 66 contains a chip card 67 and a memory 68. The RDS decoder 63 provides that from the output signal of the intermediate frequency stage 55 extracted RDS and TMC data and a clock signal to the control circuit 64. The control circuit 64, the RDS-TMC data like the control circuit 7 from FIG. 1 processed, provides TMC data to the card reader 66 and forms from the from card reader 66 and others received from memory 68 Data (data in spelling and phonetic transcription) control data sent to the speech synthesis circuit 65 is delivered. The speech synthesis circuit 65 generates from the Control data synthesized speech, which via the radio control circuit 57 the Audio amplifier 50 is supplied. The control circuit 64 also forms if necessary, from the tax data, a traffic report in writing, which via the Radio control circuit 57 of the display device 61 is supplied.
