Description
Die Neuerung bezieht sich auf einen Rundfunk- oder Radioempfänger gemäß Oberbegriff Schutzanspruch 1.The innovation relates to a broadcast or radio receiver according to the generic term Protection claim 1.
Rundfunkempfänger insbesondere für den UKW-Bereich sind in den unterschiedlichsten
Ausführungen bekannt, insbesondere auch solche mit digitalem Speicher zur
Speicherung einer bestimmten Anzahl von vorgewählten Sendern bzw.
Rundfunkstationen.Radio receivers, especially for the FM range, are known in a wide variety of designs, especially those with digital memory for
Storage of a certain number of preselected stations or
radio stations.
Aufgabe der Neuerung ist es, einen Rundfunk- oder Radioempfänger mit neuartigen
Merkmalen aufzuzeigen. Zur Lösung dieser Aufgabe ist ein Radioempfänger entsprechend
dem kennzeichnenden Teil des Schutzanspruches 1 ausgebildet.The aim of the innovation is to provide a broadcast or radio receiver with new
features. To solve this problem, a radio receiver is designed according to the characterizing part of claim 1.
Die Besonderheit des neuerungsgemäßen Radioempfängers besteht darin, daß die
Senderauswahl nur unter den in den Festspeicher gespeicherten Sendern bzw.
Rundfunkstationen möglich ist. Der neuerungsgemäße Radioempfänger eignet sich
insbesondere als Werbegeschenk für Privatsender oder Gruppen von Privatsendern, die
mit einem solchen Werbegeschenk Hörer für ihre Programme gewinnen wollen.The special feature of the new radio receiver is that the
Channel selection only from the channels stored in the permanent memory or
radio stations is possible. The new radio receiver is suitable
in particular as a promotional gift for private broadcasters or groups of private broadcasters who want to attract listeners to their programmes by means of such a promotional gift.
Der neuerungsgemäße Radioempfänger ist vorzugsweise als tragbarer kleiner Empfänger ausgebildet.The radio receiver according to the innovation is preferably designed as a small, portable receiver.
Weiterbildungen der Neuerung sind Gegenstand der Unteransprüche.Further developments of the innovation are the subject of the dependent claims.
Die Neuerung wird im Folgenden anhand der Figuren, die in einem vereinfachten
Blockdiagramm einen Rundfunkempfänger wiedergibt, näher erläutert.The innovation is explained below using the figures shown in a simplified
Block diagram representing a radio receiver is explained in more detail.
Der Rundfunkempfänger besteht in ansich bekannter Weise aus der mit der Antenne 1
verbundenen Eingangs- und Mischstufe 2 mit dem zugehörigen Oszillator 3, aus dem an
dem Ausgang der Stufe 2 angeschlossenen ZF-Verstärker 4, aus dem Demudolator 5 undThe radio receiver consists in a known manner of the antenna 1
connected input and mixer stage 2 with the associated oscillator 3, from the IF amplifier 4 connected to the output of stage 2, from the demudolator 5 and
A17079.DOCA17079.DOC
aifs dem an dem hieran angeschlossenen NF-Verstärker 6 mit den angeschlossenen Lautsprechern 7.aifs the NF amplifier 6 connected to it with the connected loudspeakers 7.
Der Oszillator 3 ist von einem für eine digitale Sendewahl geeigneten Schaltkreis gebildet, d.h. von einem Schaltkreis, dessen Frequenz durch ein digitales Steuersignal verändert werden kann.The oscillator 3 is formed by a circuit suitable for digital transmission selection, i.e. a circuit whose frequency can be changed by a digital control signal.
Zur Ändrung der Frequenz des Oszillators 3 dient eine beispielsweise von einem Mikroprozessor gebildeter Steuerkreis 8 mit zugehörigen Programm-Speicher 9 und Datenspeicher 10, welch letzterer beispielsweise von einem EPROM, beispielsweise EEPROM gebildet ist. Dem Schaltkreis 8 ist weiterhin eine Chipkarten-Leseinrichtung 11 zugeordnet, die u.a. einen Kartenschlitz zum Einschieben einer Chipkarte 12 sowie entsprechende Karteniesekontakte aufweist.A control circuit 8, formed for example by a microprocessor, with associated program memory 9 and data memory 10, the latter being formed for example by an EPROM, for example EEPROM, is used to change the frequency of the oscillator 3. The circuit 8 is also assigned a chip card reading device 11, which has, among other things, a card slot for inserting a chip card 12 and corresponding card reading contacts.
Mit Hilfe der Chipkarte 12 können Daten, die bestimmten, vorgegebenen Sendern oder deren Frequenzen entsprechen, in den Speicher 10 eingegeben werden. Durch Betätigen entsprechender Bedienungselemente einer Tastatur 13 können dann ausschließlich diese, im Speicher 10 abgelegten Sender durch einen manuellen Suchlauf oder aber durch einen automatischen Suchlauf (Scan-Funktion) eingestellt werden.Using the chip card 12, data that corresponds to certain, predefined stations or their frequencies can be entered into the memory 10. By operating the corresponding control elements of a keyboard 13, only these stations stored in the memory 10 can be set using a manual search or an automatic search (scan function).
Der Rundfunkempfänger kann beispielsweise auch mit einer RSD-Funktion ausgestattet sein, d.h. an dem ebenfalls von dem Steuerkreis 8 angesteuerten Display 14 wird der jeweils eingestellte Sender angezeigt.The radio receiver can also be equipped with an RSD function, for example, i.e. the currently tuned station is displayed on the display 14, which is also controlled by the control circuit 8.
Die Neuerung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, daß Änderungen sowie Abwandlungen möglich sind, ohne daß dadurch der der Neuerung zugrundeliegende Erfindungsgedanke verlassen wird. So ist es beispielsweise auch möglich, den vorstehend beschriebenen Rundfunkempfänger so auszubilden, daß der Speicher 10 ein flüchtiger Speicher, beispielsweise ein RAM ist, dessen Inhalt jeweils beim Ausschalten des Rundfunkempfängers gelöscht wird, wobei dann bei jedem Einschalten des Empfängers die auf der Chipkarte 12 vorgegebenenThe innovation was described above using an example embodiment. It goes without saying that changes and modifications are possible without thereby departing from the inventive concept underlying the innovation. For example, it is also possible to design the radio receiver described above in such a way that the memory 10 is a volatile memory, for example a RAM, the content of which is erased each time the radio receiver is switched off, whereby each time the receiver is switched on, the data specified on the chip card 12
A17079.DOCA17079.DOC
Sender bzw. deren Frequenzen bzw. die diesen Senderfrequenzen entsprechenden Daten in den Speicher 10 eingelegt werden.Transmitters or their frequencies or the data corresponding to these transmitter frequencies are stored in the memory 10.
