Abstract

The decoder is constructed as a data card (60) for a personal computer (30) and there are preliminary units (20) for receiving the data signals from an antenna or cable socket (21), demodulating it and feeding the demodulated data signals (10a) through the parallel output (22) to a suitable interface (31) of the PC. The data signals are then passed to the data card.

Description

Die Erfindung bezieht sich auf eine Empfangseinrichtung für Datensignale.The invention relates to a receiving device for data 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 D1, D2, E-plus oder GPS, in Telefonnetzen oder in Breitband-Kabelnetzen übertragen werden.In a known digital radio transmission system (DAB system) can not only digital, coded radio signals including additional signals, but also any data signals are transmitted which have no relation to the Have radio signals. These so-called "data broadcast signals" can For example, used by credit card organizations to access their Contracting party to transmit the numbers of blocked credit cards. A Similar situation arises with data signals, such as in mobile radio networks for example D1, D2, E-plus or GPS, in telephone networks or in Broadband cable networks are transmitted.

Die Aufgabe der Erfindung besteht darin, die drahtlos oder drahtgebunden übertragenen Datensignale auf der Empfangsseite einfach und kostengünstig zu handhaben.The object of the invention is to be wireless or wired transmitted data signals on the receiving side easily and inexpensively handle.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs gelöst. Die Erfindung wird anhand der einzigen Figur näher erläutert, welche ein Blockschaltbild einer als Zusatzgerät zu einem Personalcomputer ausgebildeten Empfangseinrichtung zeigt. This object is solved by the characterizing features of the claim. The invention is explained in more detail with reference to the single figure, which is a Block diagram of a trained as an additional device to a personal computer Receiving device shows.  

In der Figur ist mit dem Bezugszeichen 20 ein Vorsatzgerät 20 für einen Personalcomputer 30 bezeichnet, der an einer Buchse 21 von einer Empfangsantenne für terrestrischen Empfang oder Satellitenempfang, einem Telefonanschluß oder von einem Breitbandkabelanschluß mit trägerfrequenten Datensignalen 10 gespeist wird. Bei den Datensignalen kann es sich um die eingangs erwähnten Daten-Rundfunksignale des DAB-Systems oder um Datensignale handeln, die in Mobilfunknetzen wie z. B. D1, D2, E-plus oder GPS oder in Telefonnetzen oder in Breitbandnetzen übertragen werden. Das Vorsatzgerät 20 enthält im Falle von Daten-Funksignalen in nicht näher gezeigter, bekannter Weise einen Tuner zum Abstimmen auf die Trägerfrequenz des gewünschten Datensignals. In jedem Falle enthält das Vorsatzgerät 20 einen Demodulator zum Demodulieren des empfangenen, trägerfrequenten Datensignals.In the figure, reference number 20 denotes an attachment 20 for a personal computer 30 , which is fed to a socket 21 from a receiving antenna for terrestrial reception or satellite reception, a telephone connection or from a broadband cable connection with carrier-frequency data signals 10 . The data signals can be the data broadcast signals of the DAB system mentioned at the outset or data signals which are used in mobile radio networks such as, for. B. D1, D2, E-plus or GPS or in telephone networks or in broadband networks. In the case of data radio signals, the attachment device 20 contains a tuner for tuning to the carrier frequency of the desired data signal in a known manner, not shown in any more detail. In any case, the header 20 contains a demodulator for demodulating the received, carrier-frequency data signal.

Das demodulierte Datensignal 10a wird an einem parallelen Datenausgang 21 des Vorsatzgerätes 20 zur Verfügung gestellt, der als PC-kompatibler, 24poliger oder 12poliger Steckverbinder (Stecker oder Buchse) ausgebildet ist. Der Datenausgang 21 kann über ein mehraderiges Verbindungskabel mit einem passendem Parallelschnittstelleneingang 31 eines Personalcomputers 30 verbunden werden.The demodulated data signal 10 a is provided at a parallel data output 21 of the front 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 connecting 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 Datensignals 10a an eine Datenkarte 60 übergeben, welche in den Personalcomputer 30 als Steckkarte eingebaut ist. Da das Datensignal in der Regel nicht für die Allgemeinheit sondern nur für berechtigte Teilnehmer bestimmt ist, ist die jeweilige, momentan verwendete Codierung des Datensignals nur dem jeweils berechtigten Teilnehmer in Form der Datenkarte 60 bekannt, dessen spezieller Decoder die verschlüsselten Daten entschlüsselt. Auf diese Weise sind die übertragenen Daten gegen einen unbefugten Zugriff geschützt. 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.The personal computer 30 is a commercially available device which is connected to an input keyboard 40 and a monitor 50 . The personal computer 30 contains an interface software which controls the parallel interface input 31 . On a suitable command from this interface software, the data of the demodulated data signal 10 a, which is present in parallel at the input 31 , are transferred to a data card 60 which is built into the personal computer 30 as a plug-in card. Since the data signal is generally not intended for the general public but only for authorized subscribers, the respective coding of the data signal currently used is only known to the authorized subscriber in the form of data card 60 , whose special decoder decrypts the encrypted data. In this way, the transmitted data is protected against unauthorized access. The data decoded by the data card 60 are read into the central processor unit (CPU) and / or into a memory device of the personal computer 30 and can be processed there in the desired manner.
