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.
Der Aufbau und die Codierung dieser Verkehrsmeldungen sind in CEN ENV 12313-1 festgelegt, der auf dem Normvorschlag ALERT C, November 1990, herausgegeben vom RDS ATT ALERT Consortium, basiert. Die wesentlichen Elemente einer Verkehrsmeldung sind dabei der Ort des Geschehens (Location) und das Ereignis (Event). Diese Angaben sind katalogisiert, das heißt, daß jedem verkehrsrelevanten Ort und jedem verkehrsrelevanten Ereignis ein eindeutiger Code zugewiesen ist. Die Verkettung der Orte in der Ortstabelle entlang existierender Straßen gibt den Verlauf wieder. Außer den üblichen Einrichtungen eines Empfangsgerätes mit einem RDS-Decoder sind zur Nutzung des Verkehrsmeldungskanals TMC (Traffic Message Channel) Einrichtungen zur Decodierung, zur Speicherung, zur Weiterverarbeitung und zur Ausgabe der Verkehrsmeldungen erforderlich.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 announcements 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 a traffic-relevant event is. The concatenation of the places in the place table along 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, processing and output of the Traffic announcements required.
TMC-Meldungen können nicht nur mit Hilfe des Radio-Daten-Systems übertragen werden, sondern auch beispielsweise innerhalb des digitalen Audio-Rundfunks (DAB), insbesondere im FI-Kanal (Fast-Information-Channel). Ferner ist eine Übertragung der TMC-Meldungen über Mobilfunknetze vorgesehen, wobei sich insbesondere der SMS-Kanal eignet (SMS = Short Message Service). Dieser ist ein paketorientierter Datenkanal, der parallel zum gesprochenen Telefonat abgewickelt werden kann. Während bei den Rundfunksystemen, das heißt bei den unidirektionalen Netzen, nacheinander alle TMC-Meldungen gesendet werden, ist bei den bidirektionalen Netzen eine Übertragung auf Wunsch (Request) möglich.TMC messages can not only with the help of Radio data system are transmitted, but also for example within digital audio broadcasting (DAB), especially in the FI channel (Fast Information Channel). Furthermore, a transmission of the TMC messages is over Mobile radio networks are provided, in particular the SMS channel is suitable (SMS = Short Message Service). This is a packet-oriented data channel that runs parallel to the spoken phone call can be processed. While at the broadcasting systems, that is, the unidirectional ones Networks, all TMC messages are sent in succession with bidirectional networks, transmission on request (Request) possible.
Die Meldungen werden dabei gespeichert, um dem Benutzer jederzeit einen Abruf der zuvor eingegangenen Meldungen zu ermöglichen, beispielsweise wenn ein Fahrer sein Fahrzeug vorübergehend abgestellt hat und die Fahrt fortsetzen möchte. 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 temporarily stopped and continue the journey would like to.
WO-A-91 07029 offenbart einen Empfänger für digital codierte Meldungen, insbesondere Verkehrsmeldungen, mit einem Speicher für empfangene Meldungen, Eintragungen zum Decodieren und Verwalten der empfangenen Meldungen, wobei zum Decodieren eine Ortstabelle erforderlich ist, und mit Umschalteinrichtungen zum Umschalten des Empfangs auf verschiedene Informationsquellen.WO-A-91 07029 discloses a receiver for digitally encoded Reports, especially traffic reports, with a Memory for received messages, entries for Decoding and managing the received messages, whereby a location table is required for decoding, and with Switching devices for switching reception to different sources of information.

Geeignete Ortungseinrichtungen sind bekannt, beispielsweise GPS-Empfänger. Im übrigen hat diese Ausführungsform den Vorteil, daß der Benutzer während der Fahrt keine Gebietseingaben vorzunehmen braucht.A second embodiment of the receiver according to the invention is that a locating device is also provided is which determines the respective position of the recipient, that by comparing the position with saved Territorial boundaries are 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.
Sowohl bei der manuellen Eingabe des Gebietes als auch bei der Bestimmung des Gebietes durch eine Ortungseinrichtung kann es sich ergeben, daß mehrere Informationsquellen zum Empfang zur Verfügung stehen. Für diesen Fall ist bei einer Weiterbildung vorgesehen, daß vor dem Umschalten zwischen Informationsquellen mehrere Informationsquellen, die Meldungen für das Gebiet senden, die mit einer verfügbaren Ortstabelle codiert sind, dem Benutzer zur Auswahl angegeben werden. Both in the manual entry of the area and in the determination of the area by a location device it may be the case that several sources of information on the Reception will be available. In this case, one Training provided that before switching between Sources of information multiple sources of information that Send messages for the area with an available Location table are coded, given to the user for selection become.
Es ist absehbar, daß in Zukunft einige Informationsquellen kostenlos zur Verfügung stehen, während andere gebührenpflichtig sein werden. Um dem Benutzer in dieser Hinsicht eine Entscheidung zu erleichtern, kann ferner vorgesehen sein, daß mit der Auswahl angezeigt wird, ob die jeweilige Informationsquelle gebührenpflichtig ist. Dabei kann zur Bedienungserleichterung vorgesehen sein, daß bei Feststellung nur einer gebührenfreien Informationsquelle, die Meldungen für das Gebiet, die mit einer verfügbaren Ortstabelle codiert sind, sendet, auf diese ohne vorherige Abfrage umgeschaltet wird und daß gegebenenfalls ermittelte gebührenpflichtige Informationsquellen dem Benutzer zur Auswahl angegeben werden.It is foreseeable that in the future some sources of information are available for free while others will be subject to charges. To the user in this In order to facilitate a decision, it can also be provided that the selection shows whether the the respective information source is subject to a fee. there can be provided for ease of use that at Finding only one free information source, the notifications for the area with an available Location tables 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.
Bei dem erfindungsgemäßen Empfänger ist es möglich, daß Meldungen mindestens einer Informationsquelle über ein unidirektionales Netz oder daß Meldungen mindestens einer Informationsquelle über ein bidirektionales Netz empfangbar sind. Dabei ist es möglich, sowohl zwischen Informationsquellen innerhalb eines oder mehrerer unidirektionalen Netze umzuschalten oder zwischen Informationsquellen aus unidirektionalen Netzen auf bidirektionale Netze und umgekehrt.With the receiver according to the invention it is possible that 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 to switch unidirectional networks or between Sources of information from unidirectional networks bidirectional networks and vice versa.
Um bei der automatischen Umschaltung zwischen den Informationsquellen unerwünschte Umschaltungen zu verhindern, beispielsweise wenn ein Autofahrer entlang einer Gebietsgrenze fährt, ist es gemäß einer anderen Weiterbildung möglich, daß eine an sich vorgesehene automatische Umschaltung der Informationsquelle durch eine Bedieneingabe sperrbar ist.In order to automatically switch between the Sources of information undesirable switching prevent, for example, if a driver along a Territorial border drives, it is according to another Further training possible that an intended automatic switching of the information source by a Operator input can be blocked.
