Definitions

  • the invention relates to a receiver for digitally coded Reports, especially traffic reports, with a Memory for the received messages and with entries for decoding and managing the received messages, where a location table is required for decoding is.
  • 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
  • the messages are saved to the user to call up the previously received reports at any time enable, for example, when a driver drives his vehicle has temporarily stopped and continue the journey would like to.
  • the object of the present invention is to receive Messages from various sources of information enable without errors, in particular by using an incorrect location table at Decoding.
  • Switching devices for switching reception to different sources of information are provided. It is preferably provided that before switching another source of information is checked to determine whether the information provided by the other source of information used for coding Location table is available in the receiver that if applicable, the previously saved messages are deleted and the switching is carried out.
  • the receiver according to the invention has the advantage that the Users choose between multiple sources of information for the TMC messages and that it prevents Messages still in memory with one after one Change of information source loaded into memory other location table to be decoded, resulting in erroneous could lead to reports.
  • the training is the Invention provided that when the Place table a note to the user.
  • a first embodiment of the receiver according to the invention is that the switchover by a User input takes place. It is preferably provided that the user input is an identifier of an area for which messages should be received, what it is determined which location table (s) for the entered Area in the receiver is (are) and that a Switching to an information source takes place Messages for this area using one of the available Location tables are encoded, sends. This has the advantage that the user does not need to know which Information sources reports for the respective area send.
  • the identifier to be entered can be, for example Name or code of the area.
  • a second embodiment of the receiver according to the invention is that a locating device is also provided which determines the respective position of the recipient, that by comparing the position with saved Area boundaries is determined in which area the Receiver is located and which location table (s) for this Area in the receiver is (are) available and that a Switching to an information source takes place Messages for the area with an available Location table are coded sends. Suitable Location devices are known, for example GPS receiver. Otherwise, this embodiment has the Advantage that the user has no while driving Area entries.
  • the selection shows whether the respective information source is chargeable.
  • the notifications for the area with an available Location table are coded, sends, on this without prior Query is switched and that determined if necessary fee-based information sources for the user Selection can be specified.
  • Messages from at least one source of information about a unidirectional network or that messages at least one Information source can be received via a bidirectional network are. It is possible to choose between Sources of information within one or more switch unidirectional networks or between Sources of information from unidirectional networks bidirectional networks and vice versa.
  • the exemplary embodiment is a block diagram shown. However, this does not mean that it is on a Realization with the help of individual blocks corresponding circuits is limited.
  • the receiving device is rather in a particularly advantageous manner with the help of highly integrated circuits possible. You can digital signal processors are used, which at suitable programming in the block diagrams perform the processing steps shown.
  • the drawing shows some to explain the invention required modules of a radio receiver and specifically for receiving TMC messages Assemblies.
  • the signals broadcast by broadcasters are fed to a receiving part 2 via an antenna 1, an RDS decoder 3 is connected to its output.
  • For Control of the radio receiver via an operating unit 4 serves a microcomputer 5.
  • This is via a Frequency adjuster 6 with a control input of the Receiving part 2 and with a control input one Audio amplifier 7 connected to the desired station and the playback parameters, such as volume, treble and Depth increase, etc.
  • a speaker 8 is connected to an exit of the Audio amplifier 7, a speaker 8 is connected.
  • the audio amplifier 7 are one output signals Stereo decoders 9 and output signals one Speech synthesis device 14 can be supplied. Which of these Signals are reproduced is also from Microcomputer 5 controlled.
  • a GSM terminal 18 with an antenna 19 is used for this.
  • a switch 20 can optionally Output signals of the RDS decoder 3 or the GSM terminal 18 another, for processing the TMC messages (TMC) serving microcomputer 11 are supplied, from the TMC messages are selected for the respective data streams.
  • TMC TMC messages
  • the connection between the TMC microcomputer 11 and the GSM terminal 18 is bidirectional, so that TMC microcomputer 11 via the GSM terminal 18 can query the desired TMC messages.
  • commands from the Control unit 4 processed to output messages or Edit selection criteria in one for that provided non-volatile read / write memory 13 be filed.
  • the microcomputer 5 has control inputs of the RDS decoder 3, the GSM terminal 18 and the Switch 20 connected to a configuration of the GSM terminal 18 and the RDS decoder 3 by the To be able to perform microcomputer 5.
  • the GSM terminal 18 and the switch 20 can, as explained at the beginning, different sources of information can be selected.
  • the GSM terminal 18 and the switch 20 can, as explained at the beginning, different sources of information can be selected.
  • To the Search for information sources over the broadcast network are available to improve a second Receiving part may be provided, then in one of the Receiving parts receive a tuned station can be and with the help of the other receiving part Transmitter can be checked for TMC messages.
