  • Specifications of the radio data system for FM radio are inter alia in the publication Tech. 3244 - E, March 1984 of the European Union of Run-Down Radio Union (EBU).
  • Radio receivers with suitable RDS decoders can transmitted data in addition to the radio reception with the record and decode the same receiver.
  • the Data transmission takes place in 32 groups of 108 bits each, each group being assigned a particular service.
  • Group 8a is for transmission of digitally encoded Traffic reports provided.
  • the structure and coding of these traffic announcements are in the standard proposal ALERT C, November 1990 specified by the RDS ATT ALERT Consortium.
  • the essential elements of a traffic announcement are the Location of the event and the event. This information is cataloged, that is, to everyone traffic-relevant location and every traffic-relevant event a unique code is assigned. The concatenation of places in the place table along existing roads gives the Course again. Except the usual facilities of one Receiver with an RDS decoder are for use of the Traffic message channel TMC (Traffic Message Channel) Facilities for decoding, storage, storage Further processing and output of traffic reports required.
  • TMC Traffic Message Channel
  • Location-specific data such as the type a street, possibly a specific name of the Street, the name of the place, a second name of the place and if necessary, the geographical coordinates.
  • a digitally coded traffic announcement only be decoded if the location code and the associated Information in the list is present in the recipient. There are This requires very large amounts of data if all Traffic messages should be decoded and reproduced. This is all the more true, the greater that of a uniform standardized system is covered, for example, the largest part of Europe.
  • a radio receiver for receiving and reproducing digitally coded Traffic news, the Places and event information included with the Features of the preamble of claim 1 is for example from DE 41 12 828 or EP-A-0 623 896.
  • the object of the present invention is to provide an improved radio receiver for To indicate reception and reproduction of digitally coded traffic information, the can be used in various fields without the need for decoding and for Reproduction required data for all theoretical operating locations of the Radio receiver are stored.
  • a radio receiver according to the invention with the characterizing features of claim 1.
  • the received digitally coded Traffic reports of a device for decoding the traffic reports be fed, which required for the decoding of traffic announcements
  • Location-related data stored on a removable disk is that the decoded traffic reports playback data are derivable, wherein the Derivation of playback data required more location-based data on the removable media are stored, and that the playback data is a Play device can be fed.
  • the radio receiver according to the invention can in different countries for Reception and used to play back digitally coded traffic announcements being only the data carrier of the country concerned is to use.
  • the disk can be in the form of a standard chip card or other Memory cards, for example, according to the ISO 7816 standard, executed.
  • the Radio receiver according to the invention has the further advantage that when changes the location-based data, for example, by new roads or Motorway junctions a cheap upgrade is possible.
  • the Playback by voice output by written Display or by a graphic representation in the sense a map.
  • the speech output and at the written ad is through appropriate storage and Selection also a playback in different languages regardless of the particular area traveled.
  • Radio receiver for decoding the Traffic announcements and for the derivation of the playback data required algorithms and event-related data in a memory are stored in the radio receiver. These Data in itself does not require updating or customization to different countries or geographical areas, theirs Storage within the radio receiver is reduced however, the required space on the removable media.
  • Radio receiver may be designed such that the location-related data and the other location-related data in stored in a read-only memory. It can, however be provided that the location-related data and the further location-related data in a non-volatile rewritable memory are stored. This can a once purchased chip card from time to time to be updated.
  • the removable disk For decoding and derivation of playback data It is advantageous if on the removable disk at least one location code, one location type, references to each location neighboring places, with punctiform places references too an associated road segment, a country code, a code the database of the country to which refer to the aforementioned codes, a street name, a Street description, additional descriptions for the location type, name the place and, where appropriate, names of other places are.
  • An ad in the form of a map can thereby be allowed that also the geographical coordinates the places are stored.
  • An initial or repeated description of a exchangeable data carrier can be made such that of a central database covering several areas contains updated data, data queried and according to a Input that identifies a selected area, be selected and that the selected data in the Memory of the removable disk is written become.
  • the central database can, for example, all Location lists in Europe included. By entering a selected area via a selection menu can thus Are produced, for example, a disk Decoding and playback of traffic reports one of enable a car driver to travel frequently may belong to several countries.
  • the interchangeable Data carrier allows a particularly favorable utilization the existing storage capacity in that in one first stored on the removable disk Table for each location, except for the Decoding required data one or more Identifiers are stored and that for each one Identifier in a second on the interchangeable Disk stored table the other location-related Data is stored.
  • These preferably contain at least a place name. It can be quite advantageous only once occurring place names directly in the first Table.
  • Fig. 1 shows some to illustrate the invention required modules of a radio receiver and in dashed framed part to carry out the inventive method serving assemblies.
  • the too Receiving signals are an antenna 1 a Receiving part 2 is supplied to the output of an RDS decoder 3 and an audio amplifier 4 with a loudspeaker 5 are connected.
  • the decoding and playback of the digitally encoded Traffic information is controlled by a microcomputer 11.
  • This is connected to a memory 12, in which event-related and language-relevant data and algorithms are stored.
  • the microcomputer 11 are output signals of RDS decoders 3 can be fed. Further, the microcomputer 11 via an interface 13 with a Card write / read device connected, which is not in Fig. 1 is shown separately. In the reader, the Connection with a memory 14 on a chip card 15 via an interface also located on the chip card 16 produced.
  • a Speech provided, including in the microcomputer 11 digital Speech signals are synthesized via a Digital / analog converter 17 is supplied to the audio amplifier 4 become.
  • the traffic reports and more Information for example the type of selection of the Traffic reports by means of a display device 18 (Display) are displayed via a display driver 19 is connected to the microcomputer 11.
  • the memory 14 may be implemented as a read only memory (ROM) so that the user changes a new smart card 15, or as each newly to be described non-volatile read / write memory. This can then at Changes to the location-relevant data or a change the area of interest to the user with new data to be discribed.
  • ROM read only memory
  • Those transmitted with a digitally coded traffic message Location and event codes are language independent. So for example, a code 101 designates the event of a Traffic jams and a code 4711 for example the place Cologne. In Decoding tables in the memories 14 and 12 are therefore the Representatives corresponding to the codes in one specific national language saved.
  • the place names are in turn Country dependent, that means a location code in France shows a different location than the same code in Germany. Distinguish the places by the country code, the is transmitted separately in the radio data system.
  • the data stored in the memory 14 of the chip card 15 data are divided according to aspects of decoding and playback of the traffic reports.
  • LOC.-Type describes the type of place Point, area, road segment offset + Reference to the Loc code of the previous point or segment along a road previous motorway junction offset- Reference to the Loc code of the following point or segment along a road following motorway junction RefL if point loc .: reference to the loc.-code of the corresponding road segment RefA if point loc .: reference to the loc.-code of the associated area Country Code Country code according to / 1 / defines for which European country the Loc code applies DB code Data-Base-No. /1/ Defines the number of the Loc table for the corresponding country
