Abstract
Description
Gegenstand des Schutzrechts ist ein neuer RDS-Rundfunkempfänger, insbesondere ein RDS-Autoradio.The property right is a new RDS radio receiver, in particular an RDS car radio.
In dem Anfang 1984 definierten und mittlerweile zwischen den Rundfunksendern und entsprechend ausgerüsteten Rundfunkempfängern aufgebauten Radio-Daten-System sind auch Programmart-Kennungen vorgesehen. Ziffer 4.3 der System-Definition besagt, daß die Kennung es ermöglicht, Empfänger so zu programmieren, daß sie nur auf Programmbeiträge der gewünschten Art reagieren, d. h. nur diese über den Lautsprecher wiedergeben.Program type identifiers are also provided in the radio data system defined at the beginning of 1984 and now established between the radio transmitters and correspondingly equipped radio receivers. Section 4.3 of the system definition states that the identifier makes it possible to program receivers in such a way that they only react to program contributions of the desired type, i. H. just play them through the speaker.
Für den Einbau von Autoradios in Kraftfahrzeugen steht in aller Regel nur ein begrenzter Einbauraum mit einer schmalen Zugangsfläche zur Verfügung. Nach dem Einbau des Autoradios wird diese Zugangsfläche durch die Gerätekappe abgedeckt. Die Oberfläche dieser Gerätekappe hat aber nur für eine geringe Anzahl von Bedienelementen genügend Platz. Es ist daher bekannt, durch einen sogenannten Mode-Schalter einzelnen oder allen Bedienungselementen in den unterscheidbaren Modes unterschiedliche Schaltfunktionen zuzuordnen und den jeweils- eingeschalteten Mode im Display des Autoradios mit anzuzeigen.As a rule, only a limited installation space with a narrow access area is available for installing car radios in motor vehicles. After installing the car radio, this access area is covered by the device cap. The surface of this device cap only has enough space for a small number of controls. It is therefore known, by means of a so-called mode switch, to assign individual or all operating elements in the distinguishable modes to different switching functions and also to indicate the mode which is switched on in the display of the car radio.
Die Betätigung eines der Bedienelemente während des Einschaltzustandes eines bestimmten Modes wird in dem Mode zugeordneten Speichern festgehalten. Danach kann mittels des Mode-Schalters ein anderer Mode gewählt werden, ohne daß die zuvor gewählte Einstellung der Bedienung verlorengeht. Zur Änderung der Bedienung in dem verlassenen Mode muß mit dem Mode-Schalter dieser verlassene Mode wieder aufgerufen werden.The actuation of one of the operating elements while a certain mode is switched on is recorded in the memory associated with the mode. Another mode can then be selected using the mode switch without the previously selected setting of the operator being lost. To change the operation in the exited mode, this exited mode must be called up again using the mode switch.
Der Erfindung lag die Aufgabe zugrunde, einen speziellen Programmart-Mode (PTY-Mode) in ein vorhandenes Autoradio zu integrieren und zur leichteren Bedienung des Gerätes im PTY-Mode die erforderlichen Schaltfunktionen den vorhandenen Bedienelementen sinnvoll zuzuordnen.The object of the invention was to integrate a special program type mode (PTY mode) into an existing car radio and to make it easier to operate the device in PTY mode, assign the necessary switching functions to the existing controls.
Die Erfindung zur Lösung dieser Aufgabe ist durch die Merkmale des Patentanspruchs gekennzeichnet.The invention for solving this problem is characterized by the features of the patent claim.
Anhand eines in
- Figur 1 dargestellten Blockschaltbildes
- Figure 1 shown block diagram
Das Blockschaltbild zeigt die nachfolgend aufgeführten, für die Erfindung bedeutsamen Schaltstufen. An eine Antenne 1 ist eine HF-Stufe 2 angekoppelt, deren Abstimmeinheit 3 Stationstasten 11 und eine Suchlaufautomatik 19 umfaßt. Die HF-Stufe ist mit einer ZF-Stufe 4 verbunden, an der das NF-Signal abgreifbar ist, das über einen gesteuerten Schalter 5 einem NF-Verstärker 6 zugeführt und über einen Lautsprecher 7 wiedergegeben wird.The block diagram shows the switching stages listed below which are important for the invention. An RF stage 2 is coupled to an antenna 1, the tuning unit of which comprises 3 station keys 11 and an automatic search function 19. The HF stage is connected to an IF stage 4, from which the LF signal can be tapped, which is fed to a LF amplifier 6 via a controlled switch 5 and reproduced via a loudspeaker 7.
Vor dem Schalter 5 ist ein RDS-Decoder 8 angeschlossen, der unter anderem Ausgänge für die im RDS-Signal enthaltenen Programmart-Kennungen PTY und für die Programmkettenkennung PI besitzt. Der PTY-Ausgang ist mit einer Vergleichsstufe 9 verbunden, deren Steuerausgang an die Sendersuchlaufautomatik 19 angeschlossen ist. Zugleich steuert der Ausgang der Vergleichsstufe 9 den Schalter 5.An
Der zweite Eingang der Vergleichsstufe 9 ist mit Speichern 10a, 10b ... verbunden, die im Programmart-PTY-Mode den Stationstasten 11a, 11b ... zugeordnet sind. In die Speicher 10 ist jeweils eine Programmart-Kennung PTY einlesbar. Dazu sind die Speicher 10 mit einemKennungsgenerator 12 verbunden, der von einer Wippe 13 gesteuert wird. Die über die Wippe 13 aufgerufene Programmart-Kennung wird im Display 14 dargestellt. Dieses Display ist zur Anzeige der eingestellten Frequenz auch mit der Abstimmeinheit 3 verbunden.The second input of the
Jeder Stationstaste 11 sind Frequenzspeicher 15 und Senderkettenkennungspeicher (PI-Speicher) 16 zugeordnet, die mit der Sendersuchlaufautomatik 19 bzw. dem PI-Ausgang des RDS-Decoders 18 verbunden sind.Each station button 11 is assigned
Ferner ist jeder Stationstaste 11 ein Ringzähler 17 zugeordnet, der die Zahl der Tastenbetätigung zählt und nacheinander die PI-Speicher 16 aufruft. Daneben ist die Vergleichsstufe 9 an den Zähleingang des Ringzählers angeschlossen.Furthermore, a
Eine so aufgebaute Schaltung dient der Lösung der Aufgabe, die der Erfindung zugrundelag, auf folgende Weise.A circuit constructed in this way serves to achieve the object on which the invention is based in the following way.
Die Lösung ging von der Überlegung aus, daß ein bestimmter Autoradiobenutzer nicht alle angebotenen Programmarten das gleiche Interesse zuwendet. Somit ist es nicht erforderlich, auf alle 31 im RDS-System verfügbaren Programmarten in gleicher Weise und einfach zugreifen zu können. Daher wurden die Stationstasten zur Schnellwahl der bevorzugten Programmart bestimmt.The solution was based on the consideration that a certain car radio user does not pay the same interest to all types of programs offered. It is therefore not necessary to be able to access all 31 program types available in the RDS system in the same way and easily. For this reason, the station buttons were selected for quick selection of the preferred program type.
In dem mit dem Mode-Schalter 18 eingestellten PTY-Mode sind mit jeder Stationstaste 11 Speicher 10 verbunden, in den eine der PTY-Kennungen abgelegt werden kann. Mit einem Wippschalter 13, mit dem im normalen Rundfunk-Mode der jeweils nächste Sender aufgesucht wird, wird im PTY-Mode ein PTY-Kennungsgenerator 12 von Kennung zu Kennung fortgeschaltet. Ist dabei eine der bevorzugten Kennungen erreicht und wird innerhalb einer vorgegebenen Zeitspanne nach Betätigung des Wippschalters 13 die Stationstaste 11 gedrückt, mit der später die bevorzugte Programmart aufgerufen soll, so wird die erreichte Kennung in dem Stationstastenspeicher 10 abgelegt.In the PTY mode set with the
Bei einer späteren Betätigung der Stationstaste wird ein Sendersuchlauf mit der Suchlaufautomatik 19 im UKW-Bereich ausgelöst, im Verlauf dessen der erste Sender eingestellt wird, der die gespeicherte Programmart momentan ausstrahlt. Dessen Frequenz kann in dem Frequenzspeicher 15 abgelegt werden. Er wird zugleich im Display dargestellt. Durch erneute Betätigung der Stationstaste kann der zweite Sender eingestellt werden, der die gewünschte Programmart sendet.When the station button is pressed later, a station search is triggered with the automatic search 19 in the FM range, in the course of which the first station that broadcasts the stored program type is set. Its frequency can be stored in the
Sind bei weiteren Stationstasten andere Kennungen abgespeichert, so können bei der Einleitung jedes Suchlaufs, gleich durch welche Stationstaste auch immer, stets die Frequenzspeicher der anderen Stationstasten, die ja nunmehr Programmtasten darstellen, aktualisiert werden.If other identifiers are stored for other station buttons, the frequency memory of the other station buttons, which are now program buttons, can always be updated when initiating a search, regardless of which station button is used.
Die Speicherung der verschiedenen Senderfrequenzen, die die gleiche Programmart ausstrahlen, ist besonders dann von Vorteil, wenn diese Sender unterschiedlichen Programmketten zugeordnet sind. Jede Programmkette ist im Radio-Daten-System ein bestimmter PI-Code zugeordnet. Sind bei dem erwähnten Suchlauf Sender gleicher Programmart PTY aber unterschiedlicher Senderketten PI gefunden, so ist es zweckmäßig, auch die den Senderfrequenzen zugeordneten PI-Codes zu speichern und diese Frequenzen in den Speichern nach dem PI-Code zu ordnen. Durch mehrfache aufeinanderfolgende Betätigung der Stations-/Programmart-Taste kann man dann die Senderketten nacheinander aufrufen. Die Zahl der Betätigungen wird dazu in einem Ringzähler 17, der mit der Stations-Programmtaste 11 verbunden ist, gezählt, und bei jeder Ringzählerstellung wird ein anderer PI-Code aufgerufen.The storage of the different transmitter frequencies that broadcast the same program type is particularly advantageous if these transmitters are assigned to different program chains. Each program chain is assigned a specific PI code in the radio data system. If stations of the same program type PTY but different transmitter chains PI are found in the aforementioned search run, it is advisable to also store the PI codes assigned to the transmitter frequencies and to order these frequencies in the memories according to the PI code. The transmitter chains can then be called up one after the other by repeatedly pressing the station / program type button. For this purpose, the number of operations is counted in a
Hört ein Autofahrer einer bestimmten Programmart längere Zeit zu, so kann inzwischen einer der gespeicherten Sender seine Programmart gewechselt haben. Wird bei der Wahl die Programmtaste, unter der diese Sender bisher gespeichert waren, betätigt und stellt die Vergleichsstufe fest, daß bei Empfang dieses Senders die Programmartkennung nicht mehr richtig ist, dann schaltet die Vergleichsstufe 9 den zugeordneten Ringzähler 17 automatisch auf die nächste Stellung, d. h. auf einen Sender einer anderen Senderkette, die möglicherweise immer noch die gewünschte Programmart sendet. Ist über keinen der gespeicherten Sender das gewünschte Programm noch zu empfangen, dann wird wieder ein neuer Suchlauf über das ganze Frequenzspektrum ausgelöst, wobei die Frequenzspeicher aktualisiert werden.If a driver listens to a certain type of program for a longer period of time, one of the stored stations can now choose his program type have changed. If the program key, under which these stations were previously stored, is pressed and the comparison stage determines that the program type identifier is no longer correct when this station is received, then the
