Definitions

  • the invention relates to a receiver for digitally coded Messages with a selection facility for the received reports according to geographic criteria.
  • Radio data system an additional and inaudible transmission of digital data parallel to Broadcast programs in a data channel.
  • Specifications of the radio data system for FM radio are among others in the publication Tech. 3244-E, March 1984 of the European Runfunk Union (EBU).
  • Radio receivers with suitable RDS decoders can transmitted data in addition to audio reception with the Record and decode the same receiver.
  • For the Data transmission is 32 groups of 104 bits each provided, each of the transmitted groups one each certain service is assigned.
  • Group 8a is for Time for the transmission of digitally coded messages, in particular traffic reports.
  • the structure and coding of these traffic reports are specified in CEN ENV 12313-1, which is based on the proposed standard ALERT C, November 1990, published by RDS ATT ALERT Consortium based.
  • the essential elements of a Traffic reports are the location of the event and the event. This information is cataloged that means that every traffic-relevant place and everyone assigned a unique code to traffic-relevant events is.
  • the chaining of locations along in a location database existing roads reflect the course. Except the usual facilities of a receiving device with a RDS decoders are used to use the traffic information channel TMC (Traffic Message Channel) Decoding devices for Storage, further processing and output of the Traffic announcements required.
  • TMC Traffic Message Channel
  • Digitally coded messages can not only be used with the Radio data system are transmitted, but also for example within digital audio broadcasting (DAB), especially in the FI channel (Fast Information Channel).
  • DAB digital audio broadcasting
  • SMS Short Message Service
  • GATS global automotive telematic Standard
  • Another way to extract data for the Selection is that the user has a Service provider. For example the current position of the vehicle through a location system (for example GPS) recorded and via a cellular network transfer the service provider.
  • the service provider filters from the traffic news he receives for the Traffic area of the user relevant traffic reports out and transmits it to the user.
  • the first-mentioned possibility of obtaining the Selection data has the disadvantage that a quite cumbersome due to the limited operating options Manipulation is required or in the case of route searches a relatively large technical effort in the receiver Receiver must be driven.
  • the other way namely to claim a service provider via radio has the disadvantage that costs are also incurred, if a repeated detection and transfer of Selection data is not required at all, for example when commuting daily between home and Workplace.
  • the object of the present invention is therefore a Possibility of obtaining and entering the data for the Selection to indicate which of the disadvantages mentioned above does not have.
  • the task solved by the fact that data for the selection over a mobile data carriers can be fed. Make it preferably the data an expected route of a vehicle.
  • An advantageous embodiment of the invention Receiver includes a device that a selection of a of several data records stored on the data carrier enables each a route or an area represent. This allows the user to use several of them frequently Enter used routes or areas once and select one of them at the receiver, for example longer ones Routes that a traveler to his areas of application and the individual areas of application.
  • the data on a Coding and decoding of the messages used Support location database can a description of the route and / or the area based on the location codes available in the location database contain. It can also be beneficial for selection if the data also contains information on the respective Direction included.
  • a device for provision according to the invention of data on a mobile data carrier for the selection of digitally coded messages according to geographic criteria the object is achieved in that a device for electronic data processing with a device for Provide data recording on the mobile data carrier and has a program that is entered from geographic information generated data for selection. It is preferably provided that the data is a Description of a route and / or an area based on of location codes for a location database included for Coding and decoding of the messages is used.
  • the inventive design of this device is in simple to implement, for example by a Personal computers present everywhere today. Thereby are many operational simplifications when entering possible. It can, for example, in the case of the invention Means be provided that the geographical Information by entering street numbers and Autobahn access numbers are generated or that the geographic information are coordinates that come from a digital road map displayed on a screen can be read out by clicking on individual locations.
  • Entries from individual locations along the route can by being spared the geographical information generated by a route calculation program.
  • a particularly advantageous device is that the mobile data carrier is a smart card is.
  • Chip cards In addition to the particularly easy handling of Chip cards also have the advantage that they are tried and tested Chip card terminals available on the market for the receiver according to the invention and the inventive Facility can be used. For example also keyboards with an integrated chip card terminal on the Market available.
  • PC / SC working group
  • signals from the decoder 3 are one Microprocessor 6 supplied to the entire Controls signal processing sequence in the receiver. That is part of it among other things, processing inputs on the keyboard 7 and the display of information on a display 8.
  • the microprocessor 6 also contains the data from the RDS decoder 3 provided TMC messages decoded and sent to a Speech synthesizer 9 forwarded.
  • the one from that Speech synthesizer 9 generated audio signals are over a cross-fader 10 fed to the AF amplifier 4 in such a way that during the speech output of the TMC messages received audio signals are hidden.
  • the microprocessor 6 also selects the TMC messages based on selection criteria that are derived from data are derived from a chip card terminal 11 of a chip card 12 are supplied.
  • Fig. 2 shows a personal computer 21 with a Chip card terminal 22 is connected and via a program has, with the inputs made using the keyboard 23 and of the screen 24 can be made. These inputs will be converted into data suitable for selection and on a stores rewritable memory of the chip card 12.
  • the Generation of the necessary for the selection of the TMC messages Data can be exploited by the personal computer 21 possible input simplifications can be made.
  • the Chip card 12 can then be removed from chip card terminal 22 and inserted into the chip card terminal 11 of the receiver become.
  • the section of a digital one is on the screen 24 Street map recognizable with places A, B and C and the places connecting streets. Entering the expected Driving route from location A via location B to location C can now for example, by using the mouse 26 the locations A, B and C are clicked one after the other. Alternatively, the location A as the start and the location C as Destination can be entered in a route search program, which then the expected route is also determined.
  • Fig. 3 shows schematically the selection of the antenna 1 received and at 31 decoded TMC messages TMC, for what a selection algorithm 32 is used, further from selection data 33 read from the chip card are supplied.
  • these mean sections Selection data shown that the start of a trip the junction 34 of an A7 motorway is that the further course first via connection points AS31, AS30 Autobahn A7 leads to junction 29 of the Autobahn A7 is branched off to junction AS15 of the A2 motorway, with AS29 and AS15 as locations on their respective streets in the location database are listed and with cross references are provided, since they both belong to an interchange. After passing the connection points AS16, AS17 and others the destination is then not listed at the junction AS90 of the A2 motorway. Of the total of TMC messages arriving at the recipient only those TMC messages TMC 'remain Contain location codes which correspond to the information in the Selection data 33 fit.
