Definitions

  • the invention relates to a device for receiving digitally coded messages, in particular traffic reports, a location table is required for decoding.
  • 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 Traffic announcements provided.
  • 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 the locations along the location table 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
  • DAB digital audio broadcasting
  • FI Flust Information Channel
  • SMS Short Message Service
  • a traffic report location-related data is required, such as type a street, possibly a specific name of the Street, the name of the place, a second name of the place and if applicable, the geographic coordinates.
  • a digitally coded traffic report can only be decoded if the location code and the associated Information in the list is available in the recipient. There are therefore very large amounts of data are required if all Traffic reports should be decodable and reproducible. This applies all the more, the greater that of a uniform standardized system is covered area, for example the Federal Republic of Germany.
  • the interchangeability enables, among other things an adaptation to changes in the road network and the Decoding of TMC messages in other areas, that is usually in other countries.
  • the access time on the data relatively large, which translates into a delay that makes the message playback noticeable.
  • the object of the invention is the decoding of digital speed up coded messages and still on to be able to use current location tables.
  • this object is provided according to the invention that the Location table can be loaded into a working memory on which is accessed during decoding.
  • This device also has the advantage that the reader while receiving digitally encoded Messages can be used for other purposes for example for playing music CDs.
  • exchangeable data carriers can be a chip card, a CD-ROM, serve an MD or a DVD.
  • a second embodiment of the invention is that the location table is stored in a central facility and that a data transmission device for transmission the location table provided by the central facility is.
  • a data transmission device for transmission the location table provided by the central facility is.
  • each can the latest location tables are available.
  • Data transmission devices are suitable, for example Mobile device or a DAB receiver.
  • the Display of the location tables available on the data carrier can, for example, by a short description of the content respectively.
  • the display of several location tables, even on small ones Displays with, for example, a few lines can thereby that the information shown on the display can be rolled up and down.
  • Establishment is that the expected duration for loading the location table (s) is displayed. Another There is further development of the device according to the invention in that a check is made to see if by loading a Overwrite a place table with a more recent date has been. This prevents the user of the device according to the invention in a working memory loaded up-to-date location table overwrites with an older one. It can be provided that a warning is issued to the user. As well can be signaled to the user that the loading process completed successfully or unsuccessfully if necessary has been.
  • the invention further relates to a location table for the Decoding of digitally coded messages, in particular Traffic announcements, in a receiver, for loading in a working memory is formed.
  • a location table for the Decoding of digitally coded messages, in particular Traffic announcements, in a receiver, for loading in a working memory is formed.
  • This enables the distribution of Location tables are made on media that are significantly cheaper than other media.
  • the transmission of a location table from the Central setup can be done using procedures based on a fast and error-free transmission tailored are.
  • An advantageous embodiment of the invention Location table is that an identifier indicates that the Location table provided for loading into a working memory is. This prevents, for example, devices that not intended for loading (down-loading) the location table are, try with the location table according to the invention Decode messages.
  • the location table according to the invention is preferably in compressed form.
  • the selection of a location table from possibly several saved location tables is facilitated in that a table of contents for the location table, for example about the area covered by the location table is provided.
  • Place table in that an indication of the Storage space is provided.
  • the location table according to the invention can on a removable media or in a central Facility to be filed with a facility for Decoding of the messages via a transmission device is connectable.
  • Refinements of the location table according to the invention exist in that the date of manufacture of the interchangeable Data carrier is stored and / or that the collection date the location data is stored in the location table. So that will the latest location table makes it easier for the user to load into memory.
  • Another development of the location table according to the invention is that on the removable disk further information is stored.
  • These others Information can be digital, for example Form road map.
  • Fig. 1 shows a block diagram of the first Embodiment, namely a receiver in which signals received by an antenna 1 in a receiving part 2 selected, amplified and demodulated in the usual way become.
  • the resulting multiplex signal MPX except other circuits not shown for Playback of the audio signals fed to an RDS decoder 3, which is connected on the output side to a microcomputer 4.
  • the microcomputer 4 is used to control the device and Decoding of those contained in the RDS signals TMC messages.
  • a read / write memory 5 serves as RAM for the microcomputer 4.
  • the Microcomputer 4 with a keyboard 6 and a display 7 connected.
  • a reader 8 is also connected to the microcomputer 4 for an exchangeable data carrier 9, for example a CD-ROM or a digital video disc (DVD).
  • DAB Digital Audio Broadcasting
  • FI Fast Information
  • a data transmission device 18 for example, a mobile radio device provided with the data are transmitted to and from a central device 19 can.
  • the central device 19 is one Service company that operates each current location databases and possibly further ones Provides information. Using an entry with the Keyboard 6 can then be a table of contents from the Central facility 19 accessed and via the Data transmission device 18 to the microcomputer 4 are transmitted to finally visible on the display 7 to be made. After selecting one of the shown The central facility then provides location tables 19 accessed and stored in memory 5.
  • FIG. 3 schematically shows the content of an example Data carrier, for example a CD-ROM, with several Location tables, of which only two location tables 22, 25 are indicated.
  • the location tables each consist of one Header 23, 26 and actual location tables 24, 27.
  • the Header 23 gives an indication of the size of the location table.
  • Two dates 31, 32 mean the date of manufacture of the the location tables provided data carrier 21 and the date the collection of the following location data.
  • Each entry one Place contains a place code 33, an indication 34 about the place type, a street number 35 and an indication 36 about the type of Autobahn junction.
  • Each line also contains the name of the place 37, a reference 38 to the street previous place and a reference 39 to the following Place.
