Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren zur Datenverarbeitung in einem Rundfunkempfänger mit den Merkmalen des unabhängigen Patentanspruchs hat demgegenüber den Vorteil, daß Softwareprogramme, die auf dem Rundfunkempfänger laufen, Daten auswerten, um ihren Ablauf zu steuern. Dadurch wird ein benutzer- und/oder orts- und/oder zeitspezifischer Ablauf der Programme erreicht, wobei auch andere im Rundfunkempfänger lokal vorhandene Daten zur Ablaufsteuerung verwendbar sind. Dies führt zu einer hohen Akzeptanz bei den Nutzern dieser Rundfunkempfänger, und es bietet den Anbietern von solchen Programmen Vorteile für die Verbreitung dieser Programme. Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im unabhängigen Patentanspruch angegebenen Verfahrens zur Datenverarbeitung in einem Rundfunkempfänger möglich.The method according to the invention for data processing in a radio receiver with the features of the independent claim has the advantage that software programs that run on the radio receiver evaluate data in order to control their execution. A user- and / or location-specific and / or time-specific sequence of the programs is thereby achieved, wherein other data locally present in the radio receiver can also be used for sequence control. This leads to a high level of acceptance among users of these radio receivers, and it offers the providers of such programs advantages for the dissemination of these programs. The measures listed in the dependent claims enable advantageous developments and improvements of the method for data processing in a radio receiver specified in the independent claim.
Besonders vorteilhaft ist, daß am Rundfunkempfänger Daten eingegeben werden, die von den Programmen zur Ablaufsteuerung ausgewertet werden. Dadurch erstellt der Benutzer ein Benutzerprofil, um die für seine Befürfnisse und Neigungen den Ablauf der Programme zu steuern.It is particularly advantageous that data are entered on the radio receiver, which are evaluated by the programs for sequence control. In this way, the user creates a user profile in order to control the sequence of the programs for his needs and preferences.
Weiterhin ist von Vorteil, daß Daten mittels Rundfunksignalen empfangen werden und zur Programmablaufsteuerung genutzt werden. Dadurch ist es einem Dienstanbieter ermöglicht, den Programmablauf für seine Bedürfnisse, z.B. Werbung, zu beeinflussen.It is also advantageous that data are received by means of radio signals and used for program sequence control. This enables a service provider to program the program for his needs, e.g. Advertising, influence.

Darüber hinaus ist es von Vorteil, daß die Daten, die zur Programmablaufsteuerung benutzt werden, immer auf dem neuesten Stand gehalten werden, indem Daten neueren Datums die älteren, abgespeicherten Daten überschreiben. Dadurch wird der Programmablauf immer durch die aktuellen Bedingungen gesteuert.In addition, it is advantageous that the data which are used for program sequence control are always kept up to date by the fact that data of a more recent date overwrite the older, stored data. This means that the program sequence is always controlled by the current conditions.
Weiterhin ist von Vorteil, daß die Daten mittels des MOT (Multimedia Object Transfer) -Protokolls übertragen werden. Dadurch wird eine große Freiheit in einer Gestaltbarkeit einer Dateigröße und einer Datenmenge von DAB genutzt.Another advantage is that the data is transmitted using the MOT (Multimedia Object Transfer) protocol. As a result, great freedom in the design of a file size and a quantity of data is used by DAB.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigt Figur 1 ein Ablaufdiagramm des erfindungsgemäßen Verfahrens .An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows a flow chart of the method according to the invention.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Im folgenden werden Softwareprogramme mit Programmen oder im Singular mit Programm bezeichnet, wobei diese Programme von Rundfunkprogrammen, zum Beispiel NDR 2, zu unterscheiden sind.Software programs with programs or in the singular with program are referred to in the following, these programs being distinguished from radio programs, for example NDR 2.
Ein Rundfunkempfänger, vorzugweise für ein Kraftfahrzeug, weist Software auf, die auf einem Prozessor des Rundfunkempfängers läuft. Solch eine Software ist einA radio receiver, preferably for a motor vehicle, has software that runs on a processor of the radio receiver. Such software is one
Betriebsystem, das ein Ablaufen von auf dem Betriebssystem aufsitzenden Programmen ermöglicht. Das Betriebssystem weist zusätzlich ein Softwareelement auf, das eine geräteunabhängige Umgebung für ablaufende Programme schafft. Damit werden die Programme unabhängig von dem jeweiligen Prozessor oder dem jeweiligen Betriebssystem.Operating system that enables programs running on the operating system to run. The operating system also has a software element that creates a device-independent environment for running programs. This makes the programs independent of the respective processor or operating system.
Das Softwareelement und auch die darauf ablaufenden Programme werden mittels der weitverbreiteten Programmiersprache Java programmiert, wobei hier insbesondere sehr kleine Programme, sogenannte Applets, leicht erstellbar sind. Das Softwareelement ist demnach ein Java-Prozessor . Das Softwareelement kann im übrigen auch direkt auf dem Prozessor des Rundfunkempfängers als ein Java-Betriebssystem laufen. Eine weitere Möglichkeit ist, daß der Java-Prozessor direkt in den Prozessor integriert ist .The software element and also the programs running on it are programmed using the widely used programming language Java, with very small programs in particular, so-called applets, being easy to create here. The software element is therefore a Java processor. The software element can also run directly on the processor of the radio receiver as a Java operating system. Another way is that the Java processor is integrated directly into the processor.
Die auf dem Rundfunkempfänger ablaufenden Programme werden als Programmdaten mittels digitaler Rundfunksignale empfangen und dann im Rundfunkempfänger zusammengesetzt, um dann als Programm ablaufen zu können. Als digitales Rundfunkübertragungsverfahren wird DAB verwendet .The programs running on the radio receiver are received as program data by means of digital radio signals and then put together in the radio receiver so that they can then run as a program. DAB is used as the digital broadcasting method.
DAB ist ein digitales Rundfunkübertragungsverfahren, wobei neben dem eigentlichen Audioprogramm weitere Dateninformationen mit übertragen werden. DAB ist insbesondere auch für den mobilen Empfänger in einem Kraftfahrzeug geeignet, da die Eigenschaften von DAB auf einen mobilen Empfang ausgelegt sind. Insbesondere durch das Verteilen der Informationen tragenden Signale auf viele Trägerfrequenzen, wobei sich die Signale auf den unterschiedlichen Trägerfrequenzen gegenseitig nicht stören, wird erreicht, daß eine frequenzselektive Dämpfung das ganze Signal nicht so weit abschwächt, daß ein Empfang nicht mehr möglich ist, sondern es wird bei einer frequenzselektiven Dämpfung nur die Information die auf der Frequenz übertragen wird, die diese starke Dämpfung aufweist verlorengehen. Durch fehlerdetektierende und -korrigierende Codes kann dieser Teil der Information aber im Rundfunkempfänger wieder rekonstruiert werden. Man nennt das Verteilen der Signale auf verschiedene Trägerfrequenzen orthogonalen Frequenzmultiplex (OFDM = Orthogonal Frequency Division Multiplex) .DAB is a digital radio transmission method, whereby in addition to the actual audio program, further data information is also transmitted. DAB is also particularly suitable for the mobile receiver in a motor vehicle, since the properties of DAB are designed for mobile reception. In particular, by distributing the information-carrying signals over many carrier frequencies, the signals on the different carrier frequencies not interfering with one another, it is achieved that frequency-selective attenuation does not weaken the entire signal so much that reception is no longer possible, but rather becomes in the case of frequency-selective attenuation, only the information which is transmitted on the frequency which has this strong attenuation is lost. This part of the information can, however, be reconstructed in the radio receiver by error-detecting and correcting codes. The distribution of the signals on different carrier frequencies is called orthogonal frequency division multiplex (OFDM = Orthogonal Frequency Division Multiplex).
Diese fehlerdetektierenden und -korrigierenden Codes erfordern, daß im Rundfunksender den zu übertragenden Daten zusätzliche Daten hinzugefügt werden. Es wird demnach Redundanz hinzugefügt. Diese Redundanz wird entweder an einem Ende eines Datenblocks hinzugefügt, oder die Redundanz wird mittels einer vorgegebenen Regel an verschiedenen Positionen zwischen den Daten hinzugefügt. Im Rundfunkempfänger werden dann mittels dieser Redundanz auftretende Fehler detektiert und korrigiert.These error-detecting and correcting codes require that additional data be added to the data to be transmitted in the radio transmitter. Redundancy is therefore added. This redundancy is either added to one end of a data block, or the redundancy is added at different positions between the data using a specified rule. Errors occurring in the radio receiver are then detected and corrected using this redundancy.
Neben DAB sind auch andere digitaleIn addition to DAB, there are also other digital ones

Analoge Rundfunkverfahren weisen zuweilen digitale Träger auf, wie z.B. das bekannte RadioFrame structure, a different bandwidth and a different transmission frequency range of DAB, but here too e.g. worked with error-detecting and correcting codes and OFDM. Analog broadcasting methods sometimes have digital carriers, e.g. the well-known radio

Neben dem Empfang von Programmdaten, um mittels dieser Programmdaten die auf dem Softwareelement ablaufendenIn addition to receiving program data, the program data that runs on the software element
Programme zusammenzusetzen, können Programme, die mittels des Softwareelement ablaufen, in einem Speicher des Rundfunkempfängers bevorratet werden oder von anderen Datenquellen, zum Beispiel einer Chipkarte, geladen werden.To compile programs, programs that run using the software element can be stored in a memory of the radio receiver or loaded from other data sources, for example a chip card.
Welche Programme auf einem Rundfunkempfänger ablaufen, hängt zunächst von dem eingestellten Sender ab, wenn die Programme mittels der DAB-Rundfunksignale empfangen werden. Die Programme werden also mit einem jeweiligen Sender gekoppelt sein. Der einfachste Fall für ein solches Programm, das in einem Rundfunkempfänger abläuft, ist die Darstellung des Sendernamens und darüber hinaus die Programmart, also z.B. ob es ein Nachrichtensender oder ein Klassiksender ist. Erfindungsgemäß werden Daten aus lokalen Datenquellen oder empfangene Daten oder eingegebene Daten zur Ablaufsteuerung der Programme, die auf dem Rundfunkempfänger laufen, genutzt. Das wird sich insbesondere für Werbung eignen, denn damit wird zum einen eine ortsabhängige Werbung, z.B. für einen ansässigen Möbelmarkt, oder auch eine benutzerspezifische Werbung, z.B. für einen Benutzer, der an Unterhaltungselektronik interessiert ist, verwirklicht.Which programs run on a radio receiver initially depends on the tuned station if the programs are received using the DAB radio signals. The programs will therefore be linked to a respective station. The simplest case for such a program, which runs in a radio receiver, is the representation of the station name and, moreover, the type of program, for example whether it is a news station or a classic station. According to the invention, data from local data sources or received data or input data are used for sequence control of the programs that run on the radio receiver. This will be particularly suitable for advertising, because on the one hand location-dependent advertising, for example for a resident furniture market, or also user-specific advertising, for example for a user who is interested in consumer electronics, is realized.
Des weiteren ist es damit möglich, z.B. lokale Informationen über Veranstaltungen dem Benutzer über den Rundfunkempfänger mitzuteilen oder auch, um ihm benutzerspezifische Informationen, z.B. Börsennachrichten, mittzuteilen.It is also possible, e.g. to provide local information about events to the user via the radio receiver or also to provide him with user-specific information, e.g. Financial news to communicate.
In Figur 1 wird ein Ablaufdiagramm des erfindungsgemäßen Verfahrens dargestellt, das auf dem Prozessor des Rundfunkempfängers abläuft. In Verfahrensschritt 1 werden die DAB-Rundfunksignale empfangen. Darüber hinaus werden die empfangenen Rundfunksignale verstärkt, in eine niedrigere Zwischenfrequenz umgesetzt und gefiltert, um unerwünschte Frequenzkomponenten zu eliminieren. Dann werden die gefilterten Signale digitalisiert.FIG. 1 shows a flow chart of the method according to the invention, which runs on the processor of the radio receiver. In method step 1, the DAB broadcast signals are received. In addition, the received broadcast signals are amplified, converted to a lower intermediate frequency and filtered to eliminate unwanted frequency components. Then the filtered signals are digitized.
In Verfahrensschritt 2 werden die digitalisierten Signale dekodiert, wobei hier die fehlerdetektierenden und - korrigierenden Codes verwendet werden, um auftretende Fehler bei den digitalisierten Signalen zu korrigieren. In Verfahrensschritt 3 werden Informationen, die in einzelnen Dateien innerhalb des DAB-Rahmens übertragen werden, sortiert.In method step 2, the digitized signals are decoded, the error-detecting and correcting codes being used here to correct errors that occur in the digitized signals. In method step 3, information that is transmitted in individual files within the DAB frame is sorted.
Damit wird dann in Verfahrensschritt 4 aus sortierten Programmdaten das jeweilige Programm zusammengesetzt, wobei Nutzdaten davon getrennt behandelt werden. Solche Nutzdaten sind die Daten, die von den Programmen dargestellt werden, das sind Texte, Bilder, Audio- und Videosequenzen, also Multimedia-Daten .The respective program is then assembled in step 4 from sorted program data, useful data being treated separately therefrom. Such user data is the data that are displayed by the programs these are texts, images, audio and video sequences, i.e. multimedia data.
In Verfahrensschritt 5 werden ein oder mehrere zusammengesetzte Programme von dem Rundfunkempfänger gestartet und in Verfahrensschritt 6 suchen die gestarteten Programme nach Daten, um ihren Ablauf zu steuern.In method step 5, one or more composite programs are started by the radio receiver, and in method step 6, the started programs search for data in order to control their execution.
Diese Daten sind entweder, wie oben beschrieben, bereits in den digitalen Rundfunksignalen enthalten, oder die Daten werden von lokalen Datenquellen entnommen. Solche lokalen Datenquellen sind Geber, die mit dem Rundfunkempfänger verbunden sind. Das sind Helligkeitssensoren, Temperatursensoren, ein Ölstandssensor und ein Benzinstandssensor. Diese Geber liefern Daten, die einThis data is either already contained in the digital radio signals, as described above, or the data are taken from local data sources. Such local data sources are donors that are connected to the radio receiver. These are brightness sensors, temperature sensors, an oil level sensor and a gasoline level sensor. These donors provide data that a
Programm mit im Rundfunkempfänger vorgegebenen Werten für den jeweiligen Sensor vergleicht und bei Unterschreiten oder Überschreiten dieser Werte den Benutzer diese Veränderung mitteilt, wobei auf einer Anzeigevorrichtung des Rundfunkempfängers diese Mitteilung dargestellt wird, so daß es dem Benutzer ermöglicht wird, auf diese Veränderung zu reagieren.Program compares with the values given in the radio receiver for the respective sensor and informs the user of this change when the value falls below or exceeds this value, this message being displayed on a display device of the radio receiver, so that the user is able to react to this change.
Eine weitere Datenquelle ist eine Ortungsvorrichtung, ein GPS- (Global Positioning System) Empfänger, die dieAnother data source is a location device, a GPS (Global Positioning System) receiver that the
Ortskoordinaten des Rundfunkempfängers liefert, sofern der Rundfunkempfänger sich in der Nähe der Ortungsvorrichtung befindet. Die OrtungsVorrichtung ist hier eine Datenempfangseinrichtung .Provides location coordinates of the radio receiver if the radio receiver is in the vicinity of the locating device. The locating device is a data receiving device here.
In dem ablaufenden Programm sind dann Daten enthalten, mit denen das Programm die aktuellen Ortskoordinaten vergleicht, um zu einer ortsabhängigen Darstellung von Werbung oder lokalen Informationen zu gelangen. Der Vergleich beinhaltet eine Differenzbildung zwischen den aktuellen Koordinaten und Koordinaten, die in dem Programm als Daten abgelegt sind, und einen Vergleich der Differenz mit einer im ablaufenden Programm abgespeicherten Schwelle für die Differenz, wobei, wenn die Differenz unterhalb dieser Schwelle liegt, die ortsabhängige Darstellung für diesen Bereich dargestellt wird, und wenn nicht, dann wird diese ortsabhängige Darstellung nicht von dem Programm dargestellt. Sind mehrere ortsabhängige Darstellungen für unterschiedliche Koordinaten möglich, dann wird solch eine Differenz mit mehreren vorgegebenen Koordinaten gebildet, bis eine Differenz unterhalb der vorgegebenen Schwelle liegt oder bis alle vorgegebenen Koordinaten zur Differenzbildung benutzt wurden. Im letzteren Fall wird dann keine ortsabhängige Darstellung von Informationen durch das ablaufende Programm vorgenommen.The running program then contains data with which the program compares the current location coordinates in order to arrive at a location-dependent display of advertising or local information. The comparison includes a difference between the current coordinates and Coordinates, which are stored in the program as data, and a comparison of the difference with a threshold for the difference stored in the running program, the location-dependent representation for this area being displayed if the difference is below this threshold, and if not, then this location-dependent representation is not represented by the program. If several location-dependent representations for different coordinates are possible, then such a difference is formed with several predetermined coordinates until a difference lies below the predetermined threshold or until all predetermined coordinates have been used to form the difference. In the latter case, the running program does not display any location-dependent information.
Neben dem Rundfunkempfänger als Datenempfangseinrichtung sind auch weitere Datenempfangseinrichtungen, die mit dem Rundfunkempfänger verbunden sind, möglich. So ist ein Mobiltelefon, das auch Daten empfangen kann, mit demIn addition to the radio receiver as a data receiving device, other data receiving devices that are connected to the radio receiver are also possible. So is a mobile phone that can also receive data with the
Rundfunkempfänger verbunden und versendet Daten zu diesem Rundfunkempfänger. Solch ein Mobiltelefon kann nach dem GSM (Global System for Mobile Communication) oder dem UMTS (Universal Mobil Telecommunication System) -Standard ausgelegt sein, aber auch andere Mobilfunk-Standards, die für Datenempfang geeignet sind, sind einsetzbar. Ist der Rundfunkempfänger stationär ist auch eine Kopplung an das Telefonnetz oder der Datenempfang über Satellit möglich.Broadcast receiver connected and sends data to this broadcast receiver. Such a cell phone can be designed according to the GSM (Global System for Mobile Communication) or the UMTS (Universal Mobile Telecommunication System) standard, but other cell phone standards that are suitable for data reception can also be used. If the radio receiver is stationary, coupling to the telephone network or receiving data via satellite is also possible.
Lokale Daten werden auch von dem Benutzer amLocal data is also provided by the user on
Rundfunkempfänger eingegeben. So gibt der Benutzer an, ob er an bestimmten Veranstaltungen interessiert ist, welches Alter er hat, um eine Zielgruppe für bestimmte Werbeanbieter zu ermitteln, oder welche weiteren Interessen er hat, z.B. bezüglich von Bestsellern, Musik oder Sport. Eine Tastatur, über die der Benutzer am Rundfunkempfänger seine Eingaben macht, ist ein Geber.Broadcast receiver entered. The user indicates whether he is interested in certain events, what age he is in order to identify a target group for certain advertising providers, or what other interests he has, for example with regard to bestsellers, music or sports. A keyboard, Via which the user makes his entries on the radio receiver is a donor.
Ein Programm, das Nachrichten darstellt, wird unter Ausnutzung dieser Daten primär Sportnachrichten für denA program that displays news is primarily using this data sports news for the
Benutzer darstellen, wenn der Benutzer eingegeben hat, daß der Benutzer an Sport interessiert ist.Display user if the user has entered that the user is interested in sports.
Der Java-Prozessor weist Schnittstellen auf, mit denen die verschiedenen Datenquellen angesprochen werden. Das ablaufende Programm greift auf diese Schnittstellen zu, um die Daten von den einzelnen Datenquellen zu laden.The Java processor has interfaces with which the various data sources are addressed. The running program accesses these interfaces to load the data from the individual data sources.
In Verfahrensschritt 7 werden diese Daten geladen, um in Verfahrensschritt 8 entsprechend den oben gemachten Angaben ausgewertet zu werden. In Verfahrensschritt 9 wird dann entsprechend der Auswertung der Ablauf des Programms gesteuert .In method step 7, these data are loaded in order to be evaluated in method step 8 in accordance with the information given above. In step 9, the execution of the program is then controlled in accordance with the evaluation.
Daten, die mittels DAB-Rundfunksignalen empfangen werden, werden solange gepuffert, bis sie von den Programmen untersucht werden. Damit ist gewährleistet, daß zur Ablaufsteuerung der Programme alle nutzbaren Daten verwendet werden .Data received using DAB broadcast signals are buffered until they are examined by the programs. This ensures that all usable data are used for the sequential control of the programs.
Durch das Überschreiben von Daten neueren Datums wird es erreicht, daß die von den Programmen untersuchten Daten zur Ablaufsteuerung immer auf dem neuesten Stand sind. Dabei werden Ortskoordinaten mit neuen Ortskoordinaten überschrieben und benutzerspezifische Eingaben mit neuen benutzerspezifischen Eingaben überschrieben.By overwriting more recent data, it is achieved that the data examined by the programs for sequence control are always up to date. Location coordinates are overwritten with new location coordinates and user-specific entries are overwritten with new user-specific entries.
Durch das Aufteilen der Daten bei der Übertragung mittels DAB Rundfunksignalen im MOT-Rahmen wird eine große Flexibilität in der Adressierbarkeit und Größe der einzelnen Daten erreicht. Das MOT-Protokoll erlaubt die Adressierung von 268 Megabyte. Die Daten, die für das Zusammensetzen von Programmen und die Multimedia-Daten werden mittels MOT- Rahmen übermittelt. By dividing the data during transmission using DAB radio signals in the MOT frame, there is great flexibility in the addressability and size of the individual Data reached. The MOT protocol allows the addressing of 268 megabytes. The data required for the compilation of programs and the multimedia data are transmitted by means of a MOT frame.
