Rundfunksystem, Verfahren und Rundfunkempfänger zum Empfang von Sender- oder ProgrammdatenRadio system, method and radio receiver for receiving transmitter or program data
Die Erfindung betrifft ein Rundfunksystem mit Rundfunksendern, denen eine Programmidentifikation zugeordnet ist, und mit Rundfunkempfängern, die mit einer optischen Anzeigevorrichtung zur Wiedergabe der Programmidentifikation oder anderer Daten ausgestattet sind.The invention relates to a radio system with radio transmitters to which a program identification is assigned and with radio receivers that are equipped with an optical display device for displaying the program identification or other data.
Die Erfindung betrifft weiter ein Verfahren zum Empfang und zur Wiedergabe von Sender- oder Programmdaten über Sender mit Programmidentifikation mittels eines Rundfunkempfängers, der Programmidentifikationen oder andere Daten optisch anzeigt.The invention further relates to a method for receiving and playing back transmitter or program data via transmitters with program identification by means of a radio receiver, which optically displays program identifications or other data.
Die Erfindung betrifft weiter einen Rundfunkempfänger zum Empfang von Programmidentifikationen oder anderer Daten, die von Rundfunksendern ausgestrahlt werden und mittels einer optischen Anzeigevorrichtung des Rundfunkempfängers anzeigbar sind.The invention further relates to a radio receiver for receiving program identifications or other data which are broadcast by radio transmitters and can be displayed by means of an optical display device of the radio receiver.
Zur Übertragung von Informationen über Rundfunksender von den Rundfunksendern zu Rundfunkempfängern, insbesondere Autoradios, wurde das Radiodatensystem, abgekürzt RDS , eingeführt. RDS-taugliche Rundfunksender senden eine Programmidentifikation, abgekürzt PI, und einen Stationsnamen aus, der von einem RDS-tauglichen Empfänger empfangbar und auf einem kleinen Bildschirm, einem sog. Display, anzeigbar ist, so daß der Benutzer auf dem Bildschirm ablesen kann, welcher Sender oder welches Programm eingestellt ist.The radio data system, abbreviated to RDS, was introduced to transmit information about radio stations from the radio stations to radio receivers, in particular car radios. RDS-compatible radio transmitters transmit a program identification, abbreviated PI, and a station name, which can be received by an RDS-compatible receiver and displayed on a small screen, a so-called display, so that the user can read on the screen which station or which program is set.
Die Programmidentifikationen der Rundfunksender sind abstrakte Codes, die nicht auf dem Bildschirm angezeigt werden, sondern vom Rundfunkempfänger genutzt werden, um die empfangbaren Sender zu identifizieren und um gleiche auf verschiedenen Frequenzen sendenden Sender einander zuordnen zu können. Auf dem Bildschirm wird nur der ebenfalls übertragene Stationsname angezeigt . Außer der Programmidentifikation PI werden beim RDS die Programmartkennung PTY, welche die Art des Programms, z. B. Musiksendung, Nachrichtensendung usw. anzeigt, die Verkehrs- durchsagekennung TA und der Radiotext RT ausgesendet, der programmbegleitende Informationen enthält, wie z. B. Hinweise auf Musikstücke, Interpreten, Programmänderungen und dergleichen.The program identifications of the radio transmitters are abstract codes that are not displayed on the screen, but are used by the radio receiver to identify the receivable transmitters and to be able to assign the same transmitters transmitting on different frequencies to one another. Only the station name that was also transmitted is displayed on the screen. In addition to the program identification PI, the program type identifier PTY, which defines the type of program, e.g. B. shows music broadcast, news broadcast, etc., the traffic announcement identifier TA and the radio text RT, which contains program-related information, such as. B. Notes on pieces of music, artists, program changes and the like.
Traffic Message Chanel - abgekürzt TMC - ist ein Datenstrom, der ähnlich wie die Stationsnamen mit dem Rundfunksignal ausgestrahlt und vom Rundfunkempfänger empfangen wird. Hierzu ist jedoch ein TMC-tauglicher Rundfunkempfänger erforderlich, der in vorteilhafter Weise mit einem Navigationsgerät kombiniert sein kann.Traffic Message Chanel - TMC for short - is a data stream that, like station names, is broadcast with the broadcast signal and received by the broadcast receiver. For this, however, a TMC-compatible radio receiver is required, which can advantageously be combined with a navigation device.
Weil bei den gegenwärtigen Autoradios der Bildschirm auf eine Anzeige von acht alphanumerischen Zeichen beschränkt ist, werden längere Stations- und Programmnamen verkürzt gesendet und wiedergegeben. Eine vollständige Wiedergabe ist nur mittels einer Laufschrift möglich, deren Lesen aber umständlich ist und den Fahrer von seiner eigentlichen Aufgabe, dem sicheren Führen eines Fahrzeugs, nur ablenkt. Abgesehen davon enthält die PI keine näheren Daten über die Sender und die Programme.Because the screen in current car radios is limited to eight alphanumeric characters, longer station and program names are broadcast and played back in shortened form. A complete reproduction is only possible by means of a ticker, but reading it is cumbersome and only distracts the driver from his actual task of driving a vehicle safely. Apart from that, the PI does not contain any further data about the transmitters and the programs.
Es ist daher Aufgabe der Erfindung, ein Rundfunksystem, ein Verfahren sowie einen Rundfunkempfänger zum Empfang und zur Anzeige von Sender- oder Programmdaten so zu gestalten, daß dem Benutzer eine bequeme Möglichkeit zur umfassenden Information über Sender und Programme zur Verfügung gestellt wird.It is therefore an object of the invention to design a radio system, a method and a radio receiver for receiving and displaying transmitter or program data so that the user is provided with a convenient way of providing comprehensive information about transmitters and programs.
Bei einem Rundfunksystem wird diese Aufgabe mit den im Anspruch 1 angegebenen Merkmalen dadurch gelöst, daß ein Server vorgesehen ist, von dem über die Rundfunksender mit Programmidentifikation gespeichterte Daten abfragbar und von der opti- sehen Anzeigevorrichtung der Rundfunkempfänger wiedergebbar sind.In a radio system, this object is achieved with the features specified in claim 1 in that a server is provided, from which data stored via the radio transmitter with program identification can be queried and reproduced by the optical display device of the radio receiver.
Bei einem Verfahren zur Übertragung und zum Empfang von Sender- oder Programmdaten in einem Rundfunksystεm wird diese Aufgabe mit den Merkmalen des Anspruchs 8 dadurch gelöst, daß ein Server vorgesehen wird, in dem Daten über die Rundfunksender gespeichert werden, die von einem Rundfunkempfänger abgefragt und mittels einer optischen Anzeigevorrichtung wiederge- geben werden .In the case of a method for transmitting and receiving transmitter or program data in a broadcasting system, this is used Object achieved with the features of claim 8 in that a server is provided in which data about the radio transmitter are stored, which are queried by a radio receiver and reproduced by means of an optical display device.
Bei einem Verfahren zum Empfang von Sender- oder Programmdaten wird diese Aufgabe mit den im Anspruch 15 angegebenen Merkmalen dadurch gelöst, daß nach Empfang der Programmidentifikati- on eines eingestellten Senders von einem Server Daten über diesen eingestellten Sender abgerufen und mittels einer optischen Anzeigevorrichtung wiedergegeben werden.In a method for receiving transmitter or program data, this object is achieved with the features specified in claim 15 in that after receipt of the program identification of a set transmitter, data about this set transmitter is called up by a server and displayed by means of an optical display device.
Bei einem Rundfunkempfänger wird diese Aufgabe mit den im An- spruch 21 angegeben Merkmalen dadurch gelöst, daß nach Empfang der Programmidentifikation eines eingestellten Senders von einem Server Daten über diesen eingestellten Sender abrufbar und mittels einer optischen Anzeigevorrichtung wiedergebbar sind.In the case of a radio receiver, this object is achieved with the features specified in claim 21 in that after receiving the program identification of a set transmitter, data can be called up by a server via this set transmitter and can be reproduced by means of an optical display device.
Das erfindungsgemäße Rundfunksystem besteht aus Rundfunksendern, denen eine Programmidentifikation zugeordnet ist, einem Server, in welchem Daten über die Rundfunksender mit Programmidentifikation gespeichert sind und Rundfunkempfängern, die mit einer optischen Anzeigevorrichtung zur Wiedergabe der Pro- grammidentifikation und weitere Daten eines eingestellten Senders ausgerüstet sind.The radio system according to the invention consists of radio transmitters to which a program identification is assigned, a server in which data about the radio transmitters with program identification are stored and radio receivers which are equipped with an optical display device for reproducing the program identification and other data of a set transmitter.
Die im Server gespeicherten Daten der Rundfunksender mit Programmidentifikation sind z. B. mittels eines Telefons, vor- zugsweise eines GSM-Telefons, vom Server abrufbar und auf der optischen Anzeigevorrichtung der Rundfunkempfänger wiedergebbar. Die Darstellungskapazität der optischen Anzeigevorrichtungen ist genügend groß gewählt, um alle über einen Rundfunksender im Server gespeicherten Daten mit einem Bild anzeigen zu können. Im Falle eines Displays als Bildschirm ist eineThe data stored in the server of the broadcasters with program identification are e.g. B. can be called up by means of a telephone, preferably a GSM telephone, from the server and reproduced on the optical display device of the radio receiver. The display capacity of the optical display devices is selected to be large enough to be able to display all the data stored in the server via a radio transmitter with an image. In the case of a display as a screen is one
Darstellungskapazität von mehr als den üblichen acht alphanumerischen Zeichen vorgesehen. Eine Ausgestaltung des erfindungsgemäßen Rundfunksystems sieht vor, die Programmidentifikation oder den RDS-Stationsnamen des gerade eingestellten Rundfunksenders auf der optischen Anzeigevorrichtung anzuzeigen, wenn nach Ablauf einer vorgebbaren Zeitspanne nach der Anfrage beim Server keine Daten vom Server empfangen werden.Display capacity of more than the usual eight alphanumeric characters is provided. An embodiment of the broadcasting system according to the invention provides for the program identification or the RDS station name of the broadcasting station currently being set to be displayed on the optical display device if, after a predeterminable period of time after the request from the server, no data is received from the server.
Eine weitere Ausgestaltung des erfindungsgemäßen Rundfunksystems sieht vor, die Daten aller jeweils empfangbaren Rund- funksender vom Server gebündelt abzufragen und in einem Speicher der Rundfunkempf nger zu speichern. Bei Abstimmung auf einen Sender werden die diesem Sender zugeordneten Daten aus dem Speicher des Rundfunkempfängers gelesen und mittels der optischen Anzeigevorrichtung wiedergegeben. Besonders vorteil- haft ist es, vor der gebündelten Abfrage beim Server dem Server den Standort des anfragenden Rundfunkempfängers mitzuteilen. Der Server erkennt dann am Standort des anfragenden Rundfunkempfängers, welche Sender als empfangbare Sender in Frage kommen und übermittelt deshalb die Daten dieser Rundfunksender zum Rundfunkempfänger, wo sie wie bereits erwähnt in einem Speicher gespeichert werden.A further embodiment of the broadcasting system according to the invention provides for the data of all the receivable broadcasting stations to be bundled by the server and to be stored in a memory of the broadcasting receivers. When tuning to a transmitter, the data assigned to this transmitter are read from the memory of the radio receiver and reproduced by means of the optical display device. It is particularly advantageous to inform the server of the location of the requesting radio receiver before the bundled query at the server. The server then recognizes at the location of the requesting radio receiver which transmitters are suitable as receivable transmitters and therefore transmits the data of these radio transmitters to the radio receiver, where, as already mentioned, they are stored in a memory.
Wenn ein Navigationsgerät oder ein GSM-Telefon an Bord des Fahrzeuges ist, ist dessen jeweiliger Standort bekannt und kann zum Server übermittelt werden.If a navigation device or a GSM telephone is on board the vehicle, its location is known and can be transmitted to the server.
Eine weitere Ausgestaltung des erfindungsgemäßen Rundfunksystems sieht vor, daß Daten vom Server gegen Gebühr abgefragt werden. Die Gebühr kann beispielsweise mit den Telefongebühren verrechnet werden.A further embodiment of the broadcasting system according to the invention provides that data is queried from the server for a fee. For example, the fee can be offset against the telephone charges.
Das erfindungsgemäße Rundfunksystem, die erfindungsgemäßen Verfahren sowie der erfindungsgemäße Rundfunkempfänger werden anhand des in Figur 1 abgebildeten Ausführungsbeispieles und des in Figur 2 dargestellten Flußdiagrammes näher beschrieben und erläutert .The radio system according to the invention, the method according to the invention and the radio receiver according to the invention are described and explained in more detail with reference to the exemplary embodiment shown in FIG. 1 and the flow chart shown in FIG.
In der Figur 1 ist ein Ausführungsbeispiel eines erfindungsgemäßen Rundfunksystems gezeige. Der Übersichtlichkeit wegen sind nur ein Rundfunksender RS und ein Rundfunkempfänger RE gezeichnet .1 shows an embodiment of a broadcasting system according to the invention. For the sake of clarity only a radio transmitter RS and a radio receiver RE are shown.
Der Rundfunksender RS strahlt über seine Sendeantenne SA Si- gnale aus, welche von der Empfangsantenne EA des Rundfunkempfängers RE empfangen werden. Die Empfangsantenne EA ist an den Eingang eines Tuners T angeschlossen, dessen Ausgang mit einem Steuergerät S verbunden ist. Dieses Steuergerät S des Rundfunkempfängers RE ist mit einem Bildschirm, vorzugsweise einem Display D, und einem GSM-Telefon GSM verbunden, das an eine Antenne AI angeschlossen ist. In einem Server SR, der an eine Antenne A2 angeschlossen ist, sind Daten über Rundfunksender mit Programmidentifikation gespeichert.The radio transmitter RS transmits signals via its transmitting antenna SA, which are received by the receiving antenna EA of the radio receiver RE. The receiving antenna EA is connected to the input of a tuner T, the output of which is connected to a control unit S. This control unit S of the radio receiver RE is connected to a screen, preferably a display D, and a GSM telephone GSM, which is connected to an antenna AI. In a server SR, which is connected to an antenna A2, data about radio transmitters with program identification are stored.
Die erfindungsgemä-ßen Verfahren werden anhand des in Figur 2 dargestellten Flußdiagrammes erläutert.The methods according to the invention are explained using the flow diagram shown in FIG.
Wenn der Bediener des Rundfunkempfängers RE, beispielsweise eines Autoradios, einen neuen Sender anfordert, wird der Tuner TU auf diesen Sender eingestellt. Sobald die Programmidentifikation PI des eingestellten Rundfunksenders RS empfangen wird, bewirkt das Steuergerät S des Rundfunkempfängers RE eine Anfrage beim Datenserver SR über das GSM-Telefon. Über das GSM- Telefon GSM wird dem Server SR die Programmidentifikation PI des eingestellten Senders übermittelt. Der Server SR sendet nun über seine Antenne A2 die zum eingestellten Sender gespeicherten Daten zur Antenne AI des GSM-Telefons GSM, das diese Daten weiter zum Steuergerät S leitet, welches eine Anzeige der Daten auf dem Bildschirm D bewirkt . Der Fahrer und die Mitfahrer können nun die über den eingestellten Rundfunksender RS vorhandenen Daten auf dem Display D lesen.If the operator of the radio receiver RE, for example a car radio, requests a new transmitter, the tuner TU is set to this transmitter. As soon as the program identification PI of the set radio transmitter RS is received, the control unit S of the radio receiver RE makes a request to the data server SR via the GSM telephone. The program identification PI of the set transmitter is transmitted to the server SR via the GSM telephone GSM. The server SR now sends via its antenna A2 the data stored on the set transmitter to the antenna AI of the GSM telephone GSM, which forwards this data to the control device S, which causes the data to be displayed on the screen D. The driver and the passengers can now read the data on the display D via the set radio transmitter RS.
Werden jedoch nach Ablauf einer vorgebbaren Wartezeit keine Daten vom Server SR empfangen, so wird vom Steuergerät S die Anfrage beim Server SR abgebrochen. Auf dem Display D wird die vom Rundfunksender RS ausgestrahlte Programmidentifikation angezeigt . Wie bereits erwähnt sieht ein Ausführungsbeispiel der Erfindung vor, daß das Steuergerät S eine gebündelte Abfrage an den Server SR richtet. Hierzu übermittelt das GSM-Telefon GSM den Standort des Fahrzeuges, der dem GSM-Telefon GSM bekannt ist oder von einem Navigationsgerät abgefragt werden kann. Vorzugsweise handelt es sich um ein gemäß dem Global Position System arbeitenden Navigationsgerät.However, if no data is received from the server SR after a predeterminable waiting time has elapsed, the request to the server SR is terminated by the control unit S. The program identification broadcast by the radio broadcaster RS is shown on the display D. As already mentioned, one exemplary embodiment of the invention provides that the control device S directs a bundled query to the server SR. For this purpose, the GSM telephone transmits the location of the vehicle that is known to the GSM telephone GSM or that can be queried by a navigation device. It is preferably a navigation device operating according to the global position system.
Der Server SR sendet nun gebündelt die Programmidentifikatio- nen der am Standort des anfragenden Rundfunkempfängers RE empfangbaren Rundfunksender zum GSM-Telefon, das sie weiter zum Steuergerät S leitet. Das Steuergerät S bewirkt, daß die vom Server SR empfangenen Daten in einem Speicher SP im Rundfunkempfänger RE gespeichert werden.The server SR now bundles the program identifications of the radio transmitters receivable at the location of the requesting radio receiver RE to the GSM telephone, which forwards them to the control unit S. The control device S causes the data received from the server SR to be stored in a memory SP in the radio receiver RE.
Bei Einstellung eines Rundfunksenders wird geprüft, ob dessen Daten im Speicher SP bereits gespeichert sind. Ist dies der Fall, werden die im Speicher SP über diesen Rundfunksender gespeicherten Daten auf dem Display angezeigt. Andernfalls er- folgt eine Anfrage beim Server auf die bereits beschriebene Weise, unter Mitteilung der Programmidentifikation des eingestellten Rundfunksenders.When a radio transmitter is tuned in, it is checked whether its data are already stored in the memory SP. If this is the case, the data stored in the memory SP via this radio transmitter are shown on the display. Otherwise, a request is made to the server in the manner already described, with notification of the program identification of the set radio station.
