BESCHREIBUNGDESCRIPTION

Die Erfindung bezieht sich auf eine Empfangseinrichtung für Daten-Funksignale.The invention relates to a receiving device for data radio signals.

Bei einem bekannten digitalen Hörfunkübertragungssystem (DAB-System) können nicht nur digitale, codierte Hörfunksignale einschließlich Zusatzsignale, sondern auch beliebige Datensignale übertragen werden, welche keinen Bezug zu den Hörfunksignalen haben. Diese sogenannten "Daten-Rundfunksignale" können beispielsweise von Kreditkartenorganisationen benutzt werden, um an ihre Vertragspartner die Nummern von gesperrten Kreditkarten zu übermitteln. Eine ähnliche Situation ergibt sich bei Datensignalen, die in Mobilfunknetzen, wie beispielsweise Dl, D2, &Egr;-plus, oder GPS übertragen werden.With a well-known digital radio transmission system (DAB system), not only digital, coded radio signals including additional signals can be transmitted, but also any data signals that have no connection to the radio signals. These so-called "data broadcast signals" can, for example, be used by credit card organizations to transmit the numbers of blocked credit cards to their contractual partners. A similar situation arises with data signals that are transmitted in mobile networks such as Dl, D2, �E-plus, or GPS.

Die Aufgabe der Erfindung besteht darin, die übertragenen Daten-Funksignale auf der Empfangsseite einfach und kostengünstig zu handhaben.The object of the invention is to handle the transmitted data radio signals on the receiving side simply and cost-effectively.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs gelöst.This problem is solved by the characterizing features of the claim.

Die Erfindung wird anhand der einzigen Figur näher erläutert, welche ein Blockschaltbild einer als Zusatzgerät zu einem Personalcomputer ausgebildeten Empfangseinrichtung zeigt.The invention is explained in more detail with reference to the single figure, which shows a block diagram of a receiving device designed as an additional device for a personal computer.

In der Figur ist mit dem Bezugszeichen 20 ein Vorsatzgerät 20 für einen Personalcomputer 30 bezeichnet, der an einer Antennen- oder Kabelbuchse 21 von einer Empfangsantenne für terrestrischen Empfang oder Satellitenempfang bzw. von einem Breitbandkabelanschluß mit trägerfrequenten Daten-Funksignalen 10 gespeist wird. Bei den Daten-Funksignalen kann es sich um die eingangs erwähnten Daten-Rundfunksignale des DAB-Systems oder um Datensignale handeln, die in Mobilfunknetzen wie z.B. Dl, D2, &Egr;-plus oder GPS übertragen werden. Das Vorsatzgerät 20 enthält in nicht näher gezeigter, bekannter Weise einen Tuner zum Abstimmen auf die Trägerfrequenz des gewünschten Daten-Funksignals und einen Demodulator zum Demodulieren des momentan empfangenen Daten-Funksignals.In the figure, the reference number 20 designates an attachment 20 for a personal computer 30, which is fed with carrier frequency data radio signals 10 from a receiving antenna for terrestrial reception or satellite reception or from a broadband cable connection at an antenna or cable socket 21. The data radio signals can be the data broadcast signals of the DAB system mentioned at the beginning or data signals that are transmitted in mobile radio networks such as Dl, D2, �E-plus or GPS. The attachment 20 contains, in a known manner (not shown in detail), a tuner for tuning to the carrier frequency of the desired data radio signal and a demodulator for demodulating the data radio signal currently being received.

Das demodulierte Daten-Funksignal 10a wird an einem parallelen Datenausgang 21 des Vorsatzgerätes 20 zur Verfügung gestellt, der als PC-kompatibler, 24-poliger oder 12-poliger Steckverbinder (Stecker oder Buchse) ausgebildet ist. Der Datenausgang 21 kann über ein mehraderiges Verbindungskabel mit einem passendem Parallel Schnittstelleneingang 31 eines Personalcomputers 30 verbunden werden.The demodulated data radio signal 10a is made available at a parallel data output 21 of the attachment 20, which is designed as a PC-compatible, 24-pin or 12-pin connector (plug or socket). The data output 21 can be connected to a suitable parallel interface input 31 of a personal computer 30 via a multi-core connection cable.

Bei dem Personalcomputer 30 handelt es sich um ein handelsübliches Gerät, das mit einer Eingabetastatur 40 und einem Monitor 50 verbunden ist. Der Personalcomputer 30 enthält eine Schnittstellen-Software, welche den Parallelschnittstelleneingang 31 steuert. Auf geeigneten Befehl dieser Schnittstellen-Software werden die am Eingang 31 parallel anliegenden Daten des demodulierten Daten-Funksignals 10a an eine Datenkarte 60 übergeben, welche in den Personalcomputer 30 als Steckkarte eingebaut ist. Da das Daten-Funksignal in der Regel nicht für die Allgemeinheit sondern nur für berechtigteThe personal computer 30 is a commercially available device that is connected to an input keyboard 40 and a monitor 50. The personal computer 30 contains an interface software that controls the parallel interface input 31. Upon appropriate command from this interface software, the data of the demodulated data radio signal 10a present in parallel at input 31 are transferred to a data card 60 that is built into the personal computer 30 as a plug-in card. Since the data radio signal is generally not intended for the general public but only for authorized

4-4-

Teilnehmer bestimmt ist, ist die jeweilige, momentan verwendete Codierung des Daten-Funksignals nur dem jeweils berechtigten Teilnehmer in Form der Datenkarte 60 bekannt, dessen spezieller Decoder die verschlüsselten Daten entschlüsselt. Auf diese Weise ist eine Geheimhaltung der übertragenen Daten gegen einen unbefugten Zugriff gewährleistet. Die von der Datenkarte 60 decodierten Daten werden in die zentrale Prozessoreinheit (CPU) und/oder in eine Speichereinrichtung des Personalcomputers 30 eingelesen und können dort in gewünschter Weise verarbeitet werden.subscriber, the respective coding of the data radio signal currently in use is only known to the authorized subscriber in the form of the data card 60, whose special decoder decrypts the encrypted data. In this way, the confidentiality of the transmitted data is ensured against unauthorized access. The data decoded by the data card 60 are read into the central processing unit (CPU) and/or into a storage device of the personal computer 30 and can be processed there as desired.
