EP0829977A2 - RDS-TMC radio receiver for processing specific regional and transregional road region notations - Google Patents

Abstract

The radio receiver provides traffic messages to a user via a display (13) or a speech output circuit (14). A control circuit (7), e.g. a microprocessor, enables the reading of data via an external memory unit (16) from e.g. a smartcard (17), or from an internal store (12). The latter stores data relating to roads at national level while the information stored in the smartcard is specific to a particular region. In each case, a suitable classification term is stored along with the road-identifying data. Under the direction of the control circuit, data is extracted in response to received traffic messages to provide additional information. This can be in the form of road names instead of their alphanumeric designations. Versions in different languages may be stored together.

Description

• zur Lieferung von aus einem Rundfunksignal abgeleiteten codierten Meldungen an wenigstens eine Speicheranordnung,
• zum Empfang von aus den codierten Meldungen abgeleiteten Steuerdaten wenigstens einer Speicheranordnung und
• zur Bildung von Meldungen aus den Steuerdaten in einer für eine Sprachausgabeschaltung geeigneten Form.

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 messages from the control data in a form suitable for a speech output 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 mother tongue 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 memory arrangement 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 TMC data can also be transmitted via the data channel of DAB, GSM or paging systems. These systems are then to be interpreted as radio receivers that receive a radio signal with TMC data.

The invention has for its object to provide a flexible radio receiver.

• daß mit der Steuerschaltung eine Lesevorrichtung zum Lesen von Daten einer externen, ersten Speicheranordnung und eine zweite Speicheranordnung gekoppelt sind und
• daß die erste Speicheranordnung zur Speicherung von Steuerdaten für regionalspezifische Straßen- oder Bereichskategorien und die zweite Speicheranordnung zur Speicherung von Steuerdaten für überregionale Straßen- oder Bereichskategorien mit jeweils einem entsprechenden Klassennamen vorgesehen sind.

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 memory arrangement and a second memory arrangement are coupled to the control circuit and
• that the first memory arrangement for storing control data for region-specific street or area categories and the second memory arrangement for storing control data for national street or area categories are each provided with a corresponding class name.

The radio receiver according to the invention is supplied with control data from two memory arrangements which are used to decode a coded one Notification are necessary. Such a memory arrangement can be, for example, an internal memory arrangement (for example semiconductor memory) arranged in the radio receiver and an external memory arrangement (for example a semiconductor memory arranged on a chip card). In order to be able to read data from the external, first memory arrangement, a reading device (eg chip card reading device) is necessary, which is intended for removing data from the first memory device arranged on the chip card. In addition to the control data for coded messages, the first memory arrangement has control data for region-specific street or area categories. Such a region-specific street category can be, for example, a "national road" in the region "France". A region-specific area category can be given for the region "Germany" the "administrative district" or for the region "Switzerland" the "canton". The second memory arrangement could, for example, be permanently installed in the radio receiver and have control data for national road or area categories that can be understood in many regions. For example, the "department road" could be saved as the road category "road" for the region-specific road categories "national road".

Class names are assigned to the respective street or area categories. If there is no area category in the first storage arrangement for a class name, the street or area category stored in the second storage arrangement is used when a message is formed. This means that region-specific street or area categories can be stored on an exchangeable storage medium (chip card) that changes from region to region. On the other, in the radio receiver built-in memory arrangement, street and area categories are stored, which are valid for national regions. This allows the radio receiver to be used much more flexibly.

When a message with a street or area name is formed, a class name assigned to the control data of the street or area name is taken from a memory arrangement. It is then checked whether control data for street or area categories are stored in the first memory arrangement for this class name. If this is the case, the corresponding control data for street or area categories are supplied by the first storage arrangement. Otherwise, the control data for street or area categories corresponding to the class names are taken from the second memory arrangement.

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. Control data assigned to such a replacement code contains frequently used designations, such as "Cologne", "junction" etc. If the control circuit receives corresponding control data for a coded message from the first or second memory arrangement, which contain at least one replacement code, the corresponding message can only then be sent (eg traffic message) for a speech output circuit and / or a display device if the control data stored under a replacement code have been fed to the control circuit. Since such replacement codes require less storage space than the control 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 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 voice output circuit are guaranteed. 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 output 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 "junction" 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. These can also be names 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". For example, if the German language is the first language, it would be 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 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.

In addition to tax data in legal and / or phonetic transcription for a coded message, the lists then contain a class name if the coded message relates to a street and area name. If a street or area name is found in a list for a coded message, the list is also checked to see which class name is assigned to this street or area name. With the help of this class name, a street or area category is extracted from the first or second storage arrangement and a message is formed together with the street or area name and the street or area category. Both storage arrangements contain additional lists assigned to storage areas with class names and control data for the assigned street or area category.

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 they are provided for use in a radio receiver for decoding traffic reports and / or weather 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 reports stored in the radio as often as required before or after the start of the journey, to listen to the traffic reports 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 control circuit 7 is, for example, a processor circuit with peripheral circuits (not shown). 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 voice output circuit 14 and possibly one or more further arrangements 15, for example a cassette drive, a CD drive, a car telephone, etc., are 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 has two connections 22 and 23, via which the power supply from the card reader 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. 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 are coupled to the bus 21 . 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 receives the program necessary for the operation of the processor 18, the RAM 26 contains data that 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 delivers a portion of the received TMC data, which each represent coded messages, via the card reader 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 output circuit 14 and / or for the display device 13. After receiving the control data, the speech output circuit 14 outputs synthesized or stored 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 speech signal from the speech output 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 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 various general data, e.g. geographic data, frequency information, etc., and a data area list (database volume list) are stored. The data area list refers to at least one sub-directory 41 (VOL) in which identification data, data from a regional database unit 42 (RDB), a replacement list (escape table) 46 (ESC) and various other additional lists 70 (ZUS) 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, for example cities, motorway exits, ferry docks. The area list 44 indicates traffic engineering areas (eg Ruhr area), administrative areas (eg Middle Franconia) or tourist areas (eg 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 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 "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 there is the replacement code (EC), in the 2nd column a description in legal form (RS) and in the 3rd column a description in phonetic transcription (LS). As Phonetic alphabet is used SAMPA (SAMPA = speech assessment methods phonetic alphabet) Frequently used name components (eg junction, motorway junction etc.), which are not region-specific but traffic-specific, can instead of in the replacement list 46 in an additional replacement list in the memory 12 of the RDS TMC radio receiver stored. 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 possible location list above contains the location code (OC) in the first column, the location name in spelling (RS) in the second column or in whole or in part 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.

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 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 area 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 the spelling and phonetic transcription entered under this replacement code in the memory 12. Here, the control circuit 7 can, for example, use the first digit to distinguish whether it has to read from the replacement list in the memory 12 or the replacement list 46 in the data ROM 28. The entry in "Westliches" is combined with the previously read "Ruhrgebiet" entry. The phonetic entries are handled in a similar manner. If only the phonetic spelling is to be put together and given to the speech output 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 corresponds to the corresponding one Specifies the street name in phonetic transcription in the replacement list. The nodes of the road sections, which each represent the beginning and end of the relevant road section, are shown 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). 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).

Street and area names are used in the various lists above. In order to take into account the different street and area names existing in different states or countries, a hierarchically structured street class and also a hierarchically structured area class are defined. The street class has the terms "Motorway", "National", "Country" and "Urban". Class names are assigned to these class terms, which indicate the road types occurring in a state or country. The class names are also assigned categories that can be announced or displayed on the display device 13. The following assignment results for German roads: class Surname category Motorway A Highway National B Federal road Country ST State road L Country road K District road Urban R Street

The class term "Motorway" is the name "A" and the category "Autobahn", the class term "National" is the name "B" and the category "Bundesstraße", the class term "Country" are the names "ST", "L "and" K "and the categories" Staatsstraße "," Landstraße "and" Kreisstraße "and the class term" Urban "the name" R "and the category" Straße ".

A corresponding table for German areas can be specified for the area class: class Surname category Order 1 SAT country Order 2 BL federal state Order 3 RB Administrative district Order 4 KR circle Municipality SD city GE local community OT district

The division class contains the terms "Order 1 to 4" and "Municipality". The class term "Order 1" is the name "SA" and the category "Country", the class term "Order 2" is the name "BL" and the category "State", the class term "Order 3" is the name "RB" and the category "administrative district", the class term "Order 4" is the name "KR" and the category "district" and the class term "municipality" are the names "SD", "GE" and "OT" and the categories "city" , "Community" and "district" assigned.

The above-mentioned class names for the street and area class are still taken into account in the place, area and section lists 43 to 45. These lists 43 to 45 each contain at least one further column, which contains the class names specify a street or area. The following section of a location list 43 shows the location code (OC), the meaning of the location code, a designation (name) and the class name: OC meaning Ref. Class name 3038 (Motorway junction Olpe) A4 / A45 A 3040 (A3 motorway) A3 A 3621 (Junction Gladbeck) A31 A 3809 (Federal road 224) B224 B 3907 (State road ST2241) ST2241 ST 3790 (District road K676) K676 K 3843 (Country road L2400) L2400 L 3950 (Bochumer Strasse) R 3987 (Pegnitzgrund) R

The first column contains the location code (OC), in the second column the meaning of the location code, in the third column the name and in the fourth column the class name of the location code. The second column is not in the location list stored on the data ROM 28 of the chip card 17 and is only intended to show what the individual location codes mean. The designation (designation) indicates either the street in question (e.g. A3 motorway) or the street or streets that are part of the locality in question (junction Gladbeck on the A31 motorway). For reasons of clarity, the legal and phonetic transcriptions have also been omitted from the section of the list of places.

A range list 44 also contains a further column for a class name. A section of such an area list 44 could have the following entries: BC meaning Class name 4587 (Bavaria) BL 4589 (Hesse) BL 4621 ([Administrative district] Arnsberg) RB 4654 ([Administrative district] Lower Franconia) RB 4764 ([District] Recklinghausen) KR 4783 (Cologne) SD 4813 ([City] Recklinghausen) SD 4934 ([Cologne-] Mühlheim) OT 4950 ([Eating-] becoming) OT

In this section of the area list 44, the legal and phonetic transcriptions are also not listed for reasons of clarity. The area code is listed in the first column of the area list, the meaning of the area code in the second column and the class of the area code in the third column. The second column is not - as already mentioned above - contained in the data ROM 28 of the chip card 17. The terms in square brackets (e.g. administrative district) serve as additional explanations, for example to be able to distinguish between city and district.

A section list 45 also contains a column to indicate the class name (e.g. "A" for freeway) of the section. If necessary, a further column can also be present in the section list 45 in order to name the section.

When a message is formed in the control circuit 7 of the RDS-TMC radio receiver for the speech output circuit 14 or the display device 13, the control circuit 7 receives control data from the data ROM 28 (first memory circuit) of the chip card 17 and from the memory 12 (second memory arrangement) delivered. This also requires control data that designates an area or a street. Due to the different street or area designations in different states, countries and regions, the same and general designations have been selected in the memory 12 for different class names. For example, the following additional lists are contained in memory 12: class Surname category Motorway A Highway National B Street Country ST L K Urban R class Surname category Order 1 SAT Area Order 2 BL Order 3 RB Order 4 KR Municipality SD city GE OT

If, when a message is formed in the control circuit 7, for example, control data for a street with the class name "B" is received from the location list 44 stored in the data ROM 28 of the chip card 17, the control circuit 7 takes the category "B" for this class name. Street "from the memory 12 if no other precise information is available on the chip card 17.

Is control data from the chip card 17 to the control circuit for an area e.g. If the class name "BL" is sent, the control circuit 7 takes the "area" category from the memory 12, provided that no further details about the area categories are stored in the data ROM 28 of the chip card 17.

A more precise specification of the category can take place if information about this is stored in additional lists 70 in the data ROM 28. Whether such additional lists exist is determined, for example, from a coding which characterizes the chip card 17. These additional lists 70 can have the following entries: class Surname category Motorway A Highway National B Federal road Country ST State road L Country road K District road Urban R Street class Surname category Order 1 SAT country Order 2 BL federal state Order 3 RB Administrative district Order 4 KR circle Municipality SD city GE local community OT district

If data from the two additional lists in the data ROM 28 can be accessed, when a message is formed in the control circuit 7, the category "federal road" for tax data with the class name "B" for example and the class "BL" for tax data an area uses the "State" category.

The control circuit 7 thus checks whether a category is stored in an additional list 70 on the chip card 17 for a class name. If this is the case, the corresponding category stored on the chip card 17 is used when forming a message. Otherwise, the category is removed from the memory 12 which is entered for the class name.

The examples used so far in the additional lists 70 apply to the state "Germany". This means that the above entries are used on a chip card 70 for the region "Germany". A chip card 17 for the region or the state "France" will have different categories from German street names. An additional list 70 for France can contain the following categories: class Surname category Motorway A Highway National N National road Country D Departmental street C. Street Urban R Street

This additional list 70, which applies to France, therefore contains the class name "A" for the class term "Motorway" and the category "Autobahn" for which Class term "National" the class name "N" and the category "National Road", for the class terms "Country" the class names "D" and "C" as well as the categories "Department Road" and "Street" and for the class term "Urban" the class name "R" and the category "street".

An additional list 70 for an area class for "France" can contain the following entries: class Surname category Order 1 SAT country Order 2 DP Department Order 4 KO Commune Municipality SD city

This additional list 70, which applies to France, lists class terms for an area class. The class term "Order 1" is the class name "SA" and the category "Country", the class term "Order 2" is the class name "DP" and the category "Department", the class term "Order 4" is the class name "KO" and the category "municipality" and the class term "municipality" is assigned to the class name "SD" and the category "city". Since the class term "Order 3" is not used in France, there is no class name or category for this.

The location, area and section lists 43 to 45 can optionally contain further columns in order to deliver further messages to the respective user of the RDS-TMC radio receiver for specific entries in the lists 43 to 46. As already mentioned above, location codes, area codes and section codes are special names for each coded message.

In order to form a complete message in the RDS-TMC radio receiver that can be processed by the speech output circuit 14 or the display device 13, a further list with 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

• P1{5024, 3783, 3796}, P2

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

• P1{(A3, Köln, Oberhausen), Anschlußstelle Köln-Dellbrück, Anschlußstelle Köln-Müllheim} + 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. Under the location code "3783" is "Köln-Dellbrück" and under the location code "3796" is entered in the spelling "Köln-Mühlheim". 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-Müllheim} + 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〉, 〈Node〉 direction 〈Node〉, between 〈Location name〉 and 〈Location name〉:

P2 =

slow-moving traffic

In the angle brackets there are variables that have to be replaced by the names given above (e.g. A3). This then results in the message:

"A3, Cologne towards Oberhausen, between the Cologne-Dellbrück junction and the Cologne-Mühlheim junction: slow-moving traffic."

As mentioned above, the section list 45 also contains a column for a class name. The class name "A" is entered under the section code "5024". The name "Autobahn" entered under the class name "A" in the memory 12 or the data ROM 28 of the chip card 17 is removed and then a complete message is formed:

"Autobahn A3, Cologne towards Oberhausen, between the Cologne-Dellbrück junction and the Cologne-Mühlheim junction: slow-moving traffic."

• 1) "Auf der Straße L2400 von Olpe nach Siegen: Straßensperrung"
• 2) "Auf der Landstraße L2400 von Olpe nach Siegen: Straßensperrung"
• 3) "Unfall auf der Straße N96 von Paris nach Lyon"
• 4) "Unfall auf der Nationalstraße N96 von Paris nach Lyon"
• 5) "Im Bereich Rheinland-Pfalz: Nebel"
• 6) "Im Bundesland Rheinland-Pfalz: Nebel"
• 7) "Verkehrsstörungen durch Manöver im Bereich Normandie"
• 8) "Verkehrsstörungen durch Manöver im Departement Normandie".

Other messages can also be processed by the radio receiver. Such messages could be as follows:

• 1) "On the L2400 road from Olpe to Siegen: road closure"
• 2) "On the L2400 road from Olpe to Siegen: road closure"
• 3) "Accident on the N96 road from Paris to Lyon"
• 4) "Accident on the N96 national road from Paris to Lyon"
• 5) "In the Rhineland-Palatinate area: fog"
• 6) "In the state of Rhineland-Palatinate: fog"
• 7) "Traffic disruptions caused by maneuvers in the Normandy area"
• 8) "Traffic disruptions caused by maneuvers in the Normandy department".

In the composition of the message 1), the class name "L" for a German-speaking user who uses the chip card 17 for the region "Germany" is found in the place list 43 for the street name. If no additional list 70 is contained on the chip card 17, the category "street" is taken from the memory 12 for the class name. If there is an additional list, the message 2) is output, in which the category "country road" is stored in the additional list 70 for the class name "L".

Messages 3) and 4) are generated for a German-speaking user with the help of a chip card for the region "France". An additional list 70 cannot be used for message 3). The category "street" is therefore specified for the class name "N" of the street name "N96". When the message 4) is formed, an additional list 70 reads that the category "national road" is entered for the class name "N".

The procedure described above is also used for messages 5) to 8). Entries in an additional list cannot be used for messages 5) and 7). For the area class name "BL" at the Message 5) the category "area" is found in the memory 12 and when the message 6) is formed the category "state" is found in an additional list 70. For the class name "DP", the category "area" is taken from the memory 12 when the message 7) is formed, and from an additional list 70 for the class name "DP", the category "department".

The measures carried out in the control circuit 7 for composing a message for 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 supplied to the speech output circuit 14.

The RDS-TMC radio receiver shown above and the chip card 17 are - as already mentioned - suitable for a user to whom the traffic news in German is communicated by means of the display device 13 and / or the speech output 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. 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" 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 there is also a first separator (¶) 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, 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 supplemented 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 in der Standardphrasenliste:

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

The location list 43, the area list 44, the section list 45, the replacement list 46 and the additional list therefore each contain non-German phonetic transcriptions if these differ from the German language. Furthermore, the standard phrase list and the street and area list contain 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 in the standard phrase list:

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

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

Köln

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

A4 ") with the street name 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, if the memory 12 contains entries for the French and German languages and the German language is set as the first language, is followed Receiving the control data from the standard phrase list, a selection has been 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.

Several languages can also be entered in the additional list 70 of the data ROM 28 (first memory arrangement) and the additional list in the memory 12 (second memory arrangement). These entries are also made according to the procedures outlined above.

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 one of a radio signal received and transmitted 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 via a plurality of lines to the RDS-TMC module 47, which contains an RDS decoder 63, a control circuit 64, a speech output circuit 65, a card reading device 66 for receiving a chip card 67 and a memory 68. 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, supplies TMC Data to the card reading device 66 and forms control data from the data received from the card reading device 66 and further from the memory 68 (data in spelling and spelling), which is supplied to the speech output circuit 65. The speech output circuit 65 generates speech synthesized from the control data, which is supplied to the audio amplifier 50 via the radio control circuit 57. The control circuit 64 also forms if necessary, a traffic report in writing from the control data, which is fed to the display device 61 via the radio control circuit 57.
