The invention relates to a navigation system provided with a drive for reading data stored on a data carrier which, in addition to navigation data (3), comprises a pregap storing identification information. The inventive drive is configured in such a way that it reads CD-information in the pregap (2) and enables or refuses an access to navigation data (3) by comparing identification data stored in the pregap (2) with specifications.

Description

AUSLESEN EINES DATENTRÄGERS DURCH EIN NAVIGATIONSSYSTEMREADING A DATA CARRIAGE BY A NAVIGATION SYSTEM
Die Erfindung betrifft ein Navigationssystem mit einem Laufwerk zum Auslesen von Navigationsdaten, die auf einem Datenträger gespeichert sind. Neben den Navigationsdaten ist auf dem Datenträger ein Pregap vorhanden. Ebenfalls betrifft die Erfindung ein Verfahren zum Betreiben eines Navigationssystems mit einem Laufwerk zum Auslesen von Navigationsdaten von einem Datenträger, der neben den Navigationsdaten ein diesen logisch vorgeordnetes Pregap aufweist.The invention relates to a navigation system with a drive for reading navigation data that are stored on a data carrier. In addition to the navigation data, there is a pregap on the data carrier. The invention also relates to a method for operating a navigation system with a drive for reading out navigation data from a data carrier which, in addition to the navigation data, has a pregap logically preceded by it.
Um digitale Datenträger, insbesondere CD-ROMs, vor unbefugter Nervielfältigung zu schützen, sind eine Vielzahl kommerzieller Produkte am Markt erhältlich, die eine Nervielfältigung verhindern sollen, ohne die Kompatibilität zur breiten Massen vorhandener Abspielgeräte zu beeinträchtigen. Die bekannten Verfahren können jedoch mit mehr oder weniger großem Aufwand umgangen werden, so dass die Gefahr einer unbefugten Vervielfältigung und Nutzung solcher unbefugt vervielfältigter Datenträger besteht.In order to protect digital data carriers, in particular CD-ROMs, from unauthorized duplication, a large number of commercial products are available on the market which are intended to prevent duplication without impairing the compatibility with the broad masses of existing playback devices. However, the known methods can be circumvented with more or less great effort, so that there is a risk of unauthorized duplication and use of such unauthorized duplicated data carriers.
Aufgabe der Erfindung ist es, ein Navigationssystem und ein Verfahren zum Betreiben eines Navigationssystems bereitzustellen, mit dem ein wirkungsvoller Kopierschutz für Datenträger mit Navigationsdaten bereitgestellt werden kann.The object of the invention is to provide a navigation system and a method for operating a navigation system with which effective copy protection for data carriers with navigation data can be provided.
Erfindungsgemäß wird diese Aufgäbe durch ein Navigationssystem mit den Merkmalen des Anspruchs 1 sowie ein Verfahren mit den Merkmalen des Anspruchs 5 gelöst. Dadurch, dass in dem Pregap des Datenträgers Identifikationsinförmalionen abgelegt sind, die von dem Laufwerk ausgelesen werden können, ist es möglich, dass die Nutzung der Navigationsdaten auf dem Datenträger an das Vorhandensein solcher Identifikationsdaten bzw. an das Vorhandensein korrekter Identifikationsdaten geknüpft werden kann. Da die marktgängigen Kopiergeräte nicht in der Lage sind, ein Pregap zu erkennen und ein solches zu kopieren, ist mit einer entsprechenden Ausgestaltung des Inhalts des Pregaps eine Nutzungsbeschränkung bzw. eine Einräumung eines Nutzungsrechtes möglich. Erst wenn die Identifikationsdaten, beispielsweise ein Copyright-According to the invention, this task is solved by a navigation system with the features of claim 1 and a method with the features of claim 5. Due to the fact that identification information ions are stored in the pregap of the data carrier and can be read from the drive, it is possible that the use of the navigation data on the data carrier depends on the presence of such identification data or on the Presence of correct identification data can be linked. Since the marketable copiers are not able to recognize a pregap and copy one, a corresponding design of the content of the pregap can limit the use or grant a right of use. Only when the identification data, for example a copyright
Vermerk, überhaupt in dem Pregap vorhanden sind, können die übrigen Navigationsdaten ausgelesen werden. Weiterhin ist vorgesehen, dass erst bei Vorliegen ganz bestimmter Identifikationsdaten eine Nutzungsberechtigung erteilt wird, also dass nur bei Kompatibilität der Identifikationsdaten mit in dem Navigationssystem abgelegten Verifikationsdaten, die übrigen Navigationsdaten ausgelesen werden können.Note that the pregap is present at all, the remaining navigation data can be read out. Furthermore, it is provided that authorization for use is only given when very specific identification data are available, that is to say that the remaining navigation data can only be read out if the identification data are compatible with verification data stored in the navigation system.
Somit können Datenträger gezielt für ein Gerät oder eine Gerätebaureihe hergestellt werden. Selbst wenn das Pregap mit kopiert werden könnte, wäre die Nutzung des Datenträgers auf eine bestimmte Modellreihe oder bestimmteThis means that data carriers can be produced specifically for a device or a device series. Even if the pregap could be copied, the use of the data carrier would be on a certain model series or certain ones
Seriennummern der entsprechenden Navigationsgeräte beschränkbar. Dadurch verlöre das Kopieren an Attraktivität, da nicht gewährleistet sein kann, dass die kopierten Datenträger in dem vorhandenen Gerät tatsächlich funktionieren.Serial numbers of the corresponding navigation devices can be restricted. This would make copying less attractive, since it cannot be guaranteed that the copied data carriers actually work in the existing device.
In einer Weiterbildung der Erfindung ist es vorgesehen, dass die Datenträger alsIn a development of the invention it is provided that the data carrier as
CD-ROM ausgebildet sind, da diese weit verbreitet, robust und leicht zu handhaben sind. Selbstverständlich können auch alternative Datenträger wie z. B. DVD eingesetzt werden, sofern das Laufwerk die Datenformate erkennen kann.CD-ROM are trained because they are widely used, robust and easy to use. Of course, alternative media such as. B. DVD can be used if the drive can recognize the data formats.
Vorteilhafterweise ist das Pregap mit der physikalischen Adresse 0:00.0 versehen und am Ende des Pregap, das beispielsweise bei der physikalischen Adresse 0:02.0 liegt, beginnt die logische Adressierung mit der Adresse 0, um einen Zugriff durch herkömmliche CD-Brenner oder andere Kopiergeräte zu vermeiden. Der Beginn des Pregap hätte theoretisch die logische Blockadresse -150. Derjenige Teil des Datenträgers, der bei ISO 9660-Dateisystemen aufgrund der logischenAdvantageously, the pregap is provided with the physical address 0: 00.0 and at the end of the pregap, which is, for example, at the physical address 0: 02.0, the logical addressing begins with the address 0 in order to allow access by conventional CD burners or other copiers avoid. The start of the pregap would theoretically have the logical block address -150. The part of the disk that is used in ISO 9660 file systems due to the logical
Blockadressierung anstelle physikalischer Adressierung nicht angesprochen werden kann, wird dabei als Pregap verstanden. In diesem Pregap, das beispielsweise eine Länge von zwei Sekunden hat, werden die Nutzungsberechtigungsdaten, Identifikationsdaten oder ein Copyright abgelegt. Erst bei Vorhandensein dieser Daten werden die übrigen Daten freigegeben. Nachfolgend wird ein Beispiel der Erfindung anhand der beigefügten Figur näher erläutert. Die einzige Figur zeigt eine schematische Darstellung der Datenstruktur auf einem Datenträger.Block addressing instead of physical addressing is understood as a pregap. The usage authorization data, identification data or a copyright are stored in this pregap, which has a length of two seconds, for example. The remaining data are only released when this data is available. An example of the invention is explained in more detail below with reference to the attached figure. The single figure shows a schematic representation of the data structure on a data carrier.
In der Figur dargestellt ist eine Datenspur 1, die aus einem Pregap 2 und einerIn the figure, a data track 1 is shown, which consists of a pregap 2 and a
Nutzdatenspur 3 besteht. Unterhalb der Datenspur 1 ist die physikalische Adresse sowohl des Pregap 2 als auch der Nutzdatenspur 3 aufgetragen. Zu Beginn des Pregap 2 besteht die physikalische Adresse aus lauter Nullen, nämlich 0 min Laufzeit und 0 sek Laufzeit bei Frame 0. Zum Ende des Pregap 2 sind zwei Sekunden Laufzeit vorbei, als Frame wird die physikalische Adresse 00 angegeben.User data track 3 exists. The physical address of both the pregap 2 and the useful data track 3 is plotted below the data track 1. At the beginning of Pregap 2, the physical address consists of all zeros, namely 0 min runtime and 0 sec runtime for frame 0. At the end of Pregap 2, two seconds runtime is over, the physical address 00 is specified as the frame.
An das Pregap 2 schließt sich die Nutzdatenspur 3 mit Navigationsdaten an, die die übrige Speichermenge einnimmt, bei einer üblichen CD sind dies 74 Minuten, was an dem rechten unteren Ende der Figur abzulesen ist. Am oberen rechten Ende der Figur ist die letzte logische Blockadresse „665850" zu erkennen.The pregap 2 is followed by the useful data track 3 with navigation data, which takes up the remaining amount of memory; in the case of a conventional CD, this is 74 minutes, which can be seen at the lower right end of the figure. The last logical block address "665850" can be seen at the upper right end of the figure.
Im vorderen Bereich ist das Pregap 2 mit der physikalischen Adresse 0:00.0 versehen, und am Ende des Pregap , das bei der physikalischen Adresse 0:02.0 liegt, beginnt die logische Adressierung, die oben aufgetragen ist, mit der Adresse 0, um einen Zugriff durch herkömmliche CD-Brenner oder andere Kopiergeräte auf das Pregap zu vermeiden. Der Beginn des Pregap hätte theoretisch die logischeIn the front area, the Pregap 2 is provided with the physical address 0: 00.0, and at the end of the Pregap, which is at the physical address 0: 02.0, the logical addressing, which is plotted above, begins with the address 0 for access Avoid using conventional CD burners or other copiers on the Pregap. The start of the pregap would theoretically be logical

Das nicht dargestellte, verwendete Leselaufwerk ist in der Lage, das Pregap 2 einer CD zu lesen, obwohl das Pregap 2 bei ISO 9660-Dateisystemen aufgrund der abweichenden Adressierungsart (logische Blockadressierung anstelle physikalischer Adressierung) nicht angesprochen werden kann.The read drive, not shown, is able to read the Pregap 2 of a CD, although the Pregap 2 cannot be addressed in ISO 9660 file systems due to the different type of addressing (logical block addressing instead of physical addressing).
Das hier implementierte Programm ergänzt die fertige Navigations-CD um einen zwei Sekunden langen Datenblock 2, in dem beispielsweise ein Copyright abgelegt wird. Es ist nun möglich, CDs mit vordefiniertem Pregap 2 zu pressen, bei denen im Navigationssystem die Existenz des Copyrights geprüft werden kann. Ist dieses nicht vorhanden, so wird die CD abgelehnt. Ein Kopieren dieser CD mit marktgängigen CD-Brennern ist nicht möglich. The program implemented here supplements the finished navigation CD with a two-second data block 2 in which, for example, a copyright is filed. It is now possible to press CDs with a pre-defined Pregap 2, on which the existence of the copyright can be checked in the navigation system. If this is not available, the CD will be rejected. Copying this CD with standard CD burners is not possible.
