Definitions
- the invention is based on a method for transmission of digitally encoded traffic news and one Radio receiver for this purpose, according to the genus of claims 1 and 7.
- receiver build up where the traffic news is standardized be transmitted.
- the highway numbers that Route names and other place names as well as the Standard texts are stored in a memory and carried in a corresponding radio receiver.
- Kick now an obstacle to traffic so the information digitally transmitted in the form of abbreviations and then in Broadcast receiver for a complete message composed. This ensures that with very few Bytes of complete traffic messages are transmitted can, so that even with less powerful Data transmission systems very many traffic news in be transmitted in a relatively short time.
- the header is also particularly advantageous to encrypt traffic messages at the same time use. This makes it possible, for example, To provide traffic news only when certain services are received or fees were paid. It is also advantageous that divide further information into classes, each Class a class identifier and at least one package having. By dividing it into classes, it is possible not only to transmit location information, but also further additional information with the Connect traffic news, for example to memory to be provided with new location data in the radio receiver or but additional foreign language texts of place names to transmit, so that foreign drivers the Receive information in your native language. It is cheap also that the number of subsequent packets after the Class identifier is transferred. This will ensures that the radio receiver is able to all information of a class is complete to record.
- the radio receiver according to the invention for performing the Method according to one of claims 1 to 6 has a Separator of digital data and voice information and an evaluation circuit for evaluating the digital transmitted traffic news.
- an evaluation circuit for evaluating the digital transmitted traffic news is included.
- the radio receiver only has a memory for standard texts. By This measure is achieved that standard texts on everyone Case do not need to be transferred.
- FIG. 1 shows a radio receiver, for example one Broadcast receiver with an antenna 1 to which a Broadcast receiving part 2 is connected.
- the decoded received Signal available.
- FM radio in addition to the spoken words and the music spoken traffic radio and via the radio data system RDS broadcast digitally encoded traffic news.
- the Coding is based on a standard that is specifically for the limited data capacity was developed by RDS.
- the received Information separated.
- the spoken words become that Amplifier 3 supplied and via the speaker 4 to the listener made audible.
- the digitally transmitted data is the Decoder 5 supplied, at the output of a serial signal with so-called TMC data is available.
- TMC messages are not only used to inform the driver, but also for dynamization navigation, i.e. when calculating before driving routes the traffic situation is taken into account in navigation systems, which was transmitted via TMC, so that for example the Navigation already gives hints on how to avoid a traffic jam is.
- the problem with TMC is that carried in the terminal Lists and tables, in particular the To be mentioned is the location code table, which is the list of all locations for the road network relevant for the traffic announcement saved.
- There is also an event list in which the possible events are listed are, for example, the length of a traffic jam and the reason why a traffic jam occurred.
- Storage space is the update of the location code tables a problem and it should be remembered that not all Traffic reports can be encoded, especially if by blocking or adding more streets Location code table is out of date.
- the event list only allows the use of the predefined events. New events can be viewed through TMC in its familiar form not be transferred. On the other hand, TMC enjoys one increasing popularity because of the standard won with very little information a lot of information can be conveyed.
- TMC is no longer only used in FM radio, but is also used in conjunction with GSM radio telephones, which also takes advantage of the TMC location with the short transmission times.
- TMC is also under discussion with new, advanced broadcast transmission systems, such as digital audio broadcasting (DAB). Due to the advanced technology, however, the newer transmission methods are able to transmit significantly higher data rates than is the case with RDS-TMC. It is essential, however, that all radio reception systems have in common that after the reception and the demodulation of the information the speech information and TMC information must be separated, which must be processed in a suitable manner in a computer.
- DAB digital audio broadcasting
- a standard TMC message 13 is broadcast expanded.
- the expanded TMC message 10 is composed of a header 12 and the actual message 11.
- the message 11 itself in turn consists of a standardized TMC message 13, as well as at least one piece of additional information 14, 15 and 16. If a header 12 precedes the TMC message 13, at least one additional piece of information 14 must be present, which is also transmitted. This additional information 14 must also be location information.
- the additional information 15 and 16 and additional information are optional and are used to transmit different classes of information.
- the header 12 is necessary in order to be able to recognize that it is an expanded TMC information.
- the header 12 may include information about how much Additional information 14, 15 and 16 of the actual TMC message follow and serves one if needed Encrypt the TMC message. Such Encryption must be signaled and at the same time must what type of encryption it is acts. A header can therefore also be used Encryption indicator must be incorporated. So it will possible to encrypt the TMC message differently and different TMC information depending on the service for example, to transmit via GSM or DAB. That's the way it is for example possible, a service provider A a first Assign encryption and a service provider B a other encryption method.
- the Header is therefore able to identify a extended TMC message to perform other tasks, such as encryption and how much Additional information is expected.
- TMC message 13 While the structure of the TMC message 13 is standardized, see above that there is no need to go into detail here the additional information can be structured differently. It is important that at least one piece of additional information 14 is a Contains location description, otherwise an extended TMC message wouldn't make sense.
- the additional information is shown in detail in FIG. 3.
- the additional information that has different contents can, is divided into so-called classes 20, where the classes from a class identifier 21, from a Class length 22, which is the number of subsequent packets describes and composed of the packages 23, 24, wherein the number of packages only by the class length 22 is determined. It is still important that certain Classes with a specific class name Minimum amount of mandatory packages is assigned, so that a optimal evaluation of the TMC data is possible. In addition however, any other packages can optionally be attached become.
- the definition of class 20 is also for the TMC message 13 itself applicable. As a class identifier the code for TMC messages is then at position 21 used, while the class length is the number of TMC messages indicates. Then as packets 23 and 24 follows one TMC group each.
- TMC message for a package several TMC messages are to be transmitted transferred, several packets are to be formed.
- the standardized traffic reports also allow that traffic information not only from a group, but also can consist of up to five groups. In this case must have a total of five packages 23, 24 for a traffic announcement be used. Recognizing the togetherness of the Packets can be seen in Figure 4, since it is shown here that each packet 23 and 24, there designated 25, on the one hand consists of type 26 and data 27. At the Type marking 26 can now be seen whether the subsequent data 27 to a previous packet belong, or whether the data 27 in itself are interpretable. TMC messages can now be due to the construction of the class several traffic reports together are transmitted via the TMC message module 13.
- one of the additional information items 14 contain a class to describe the location. And here Information from those contained in the TMC report encoded locations are included. Depending on the type the situation described in the TMC message is required one or more for such a location description different types of packages. The combination of packages in terms of number, type and order lead to education several different classes, these classes Required information included.
- Mandatory information for the Location information is, for example, packets for the Street name, for the name or short name of the Street, its numbering, coordinates, audio modules and to see something similar. This enables the in to add content transmitted in coded form to TMC data, which are constantly updated.
- the microprocessor 6 in FIG. 1 additionally contains a memory 7, in which the standardized events are stored in a special exemplary embodiment of the invention. Since the normalized events change less frequently than location data, mixed operation can also be achieved by the invention, namely by part of the necessary TMC information, in particular the events such as 3 km of traffic jam "and the like is stored in a memory of the radio receiver while other information whose change is more likely, such as place names, is transmitted. However, this is not mandatory. Of course it is possible to provide no memory at all and also to record the events as To transmit additional information, or to keep a complete location code and event list and only transmit information as extended topics for information that is not included in the location code list. It is essential that the TMC message itself with the already standardized TMC message is compatible.
- the following table 1 shows various packet types that can be transmitted as a packet in a class of additional information.
- No Package type Type length description 0 number 5 bytes TMC group 1 number 8 bytes Location: ECC + CC + LocDB # + Locationcode (according to ALERT C) 2nd number 1 byte Street class (primary, secondary, etc., coded as 1,2, etc.) 3rd Street designation n bytes Street ID (e.g. A, ST, etc.) 4th Street designation n bytes Street number (e.g. 4.1204 etc.) 5 text n bytes Street suffix (e.g. n, old, etc.) 6 Surname n bytes Street name (e.g. GmbHer Ring) 7 Surname n bytes 1.

Abstract
Description
Wesentlich ist jedoch allen Funkempfangssystemen gemeinsam, daß nach dem Empfang und der Demodulation der Information eine Trennung der Sprachinformation und TMC-Information erfolgen muß, die in geeigneter Weise in einem Rechner verarbeitet werden muß. In Figur 2 ist nun ein Verfahren zur Übertragung von digitalcodierten Verkehrsnachrichten aufgezeigt, das zum an sich bekannten TMC-Verfahren rückwärts kompatibel ist, das heißt unter der Verwendung des bekannten TMC-Verfahrens zusätzliche Informationsmöglichkeiten anbietet. Eine Standard TMC Meldung 13 wird erweitert ausgestrahlt. Die erweiterte TMC-Meldung 10 setzt sich aus einem Header 12 und der eigentlichen Meldung 11 zusammen. Die Meldung 11 selbst besteht wiederum aus einer standardisierten TMC-Meldung 13, so wie mindestens einer Zusatzinformation 14, 15 und 16. Wird ein Header 12 der TMC-Meldung 13 vorangestellt, so muß mindestens eine Zusatzinformation 14 vorhanden sein, die mit übertragen wird. Diese Zusatzinformation 14 muß zudem eine Ortsinformation sein. Die weiteren Zusatzinformationen 15 und 16 sowie weitere Zusatzinformation sind optional und dienen dazu, verschiedene Klassen von Informationen zu übertragen.
