Kombiniertes Rundfunk/Fernseh-Empfangsgerat mit nur einem Ton-Wiedergabeteil Die Erfindung bezieht sich alu den Bedienungsvorgang für ein Hochfrequenz-Empfangsgerät, das zum wechselweisen Empfang von Rundfunk-und Fernsehsendungen geeignet, in einem gemeinsamen Gehäuse untergebracht und mit nur einem Tcn-Wiedergabeteil bestückt ist.Combined radio / television receiver with only one sound reproduction part The invention relates to the operating procedure for a high-frequency receiving device, which is suitable for the alternate reception of radio and television broadcasts in one housed common housing and equipped with only one Tcn playback part is.
Es ist bekannt, kontinuierlich oder festabstimmbare Emangs schaltungen zum Empfang von hundfunk- und Fernseh-Sendungen gemeinsam in einem Gehäuse unterzubringen, wobei jedoch jeweils nur eine Betriebsart möglich ist. Mit der manuellen Betriebs-artenumschaltung erfolgt in der Regel - außer der Umschaltung der Tonen stufe - auch eine Umschaltung, bzw. Teilabschaltung des Netzteiles, um die Gesamt-Stromkosten und Verschleißerscheinungen an nicht benötigten Bauteilen gering zu halten. Dem derzeitigen Stand der Technik integrierter Schaltkreise angepaßt ist, unter dem Namen "Combistar", von KÖRTING 1977 erstmalig ein kombiniertes RF/FS-Portable mit gemeinsamer Tonendstufe vorgestellt worden, bei dem es möglich ist, auch unter Ausnutzung einer drahtlosen Fernbedienung, beliebig zwischen RF- und FSIEmpfang umzuschalten und die vorhandenen Programmspeicher beider Empfänger wahlweise über dieselben Tasten des Geräte-Bedienfeldes oder des Fernbedien-Gebers zu aktivieren.It is known, continuously or permanently tunable Emangs circuits to be housed together in one housing for the reception of dog radio and television broadcasts, however, only one operating mode is possible at a time. With manual operating mode switching As a rule, in addition to switching the tone level, there is also a switchover, or partial shutdown of the power supply unit to reduce the total electricity costs and signs of wear and tear to keep the number of unneeded components to a minimum. The current state of the art integrated circuits is adapted, under the name "Combistar", from KÖRTING In 1977 a combined RF / FS portable with a common audio output stage was presented for the first time where it is possible, also using a wireless remote control, to switch between RF and FSI reception and the existing program memory both receivers either via the same buttons on the device control panel or the To activate the remote control transmitter.
Bei allen bisher bekannt gewordenen Schaltungen wird jedoch, durch Schalten der Stromversorgung, das gerade nicht benötigte Empfangsteil abgeschaltet, sodaß jeweils immer nur eine Betriebsart gleichzeitig ausgenutzt werden kann. Will man z.B. bei laufender Rundfunkwiedergabe prüfen, ob eine bestimmte FS-Übertragung beginnt, muß man den RF-Empfänger ab- und den FSwEmpfänger einschalten, was bedeuten kann, daß man während der Anheizzeit der Bildröhre auf das Bild warten muß und bei Wiederzurückschalten auf RF-Empfang der zuvor gewählte Programmspeicherkanal nicht wieder erscheint.In all circuits known so far, however, through Switching the power supply, the currently unneeded receiver switched off, so that only one operating mode can be used at a time. Want For example, while the radio is playing, you can check whether a certain FS transmission begins you have to switch off the RF receiver and switch on the FSw receiver, which can mean that you wait for the picture while the picture tube is heating up must and when switching back to RF reception the previously selected program memory channel does not appear again.
Aufgabe der Erfindung ist es, einen kombinierten RF/FS-Empfänger über eine geeignete Schaltungsanordnung die beiden Empfänger sowohl jeweils einzeln oder auch gleichzeitig zu betreiben, daß auch während des RF-Empfangs ein FS-Empfang möglich ist. Da es in dieser, auf Wunsch einschaltbaren Betriebsart nur sinnvoLl ist, die gemeinsame Tonendstufe, mit den an deren Ausgang angeschlossenen Lautsprechern an den RF-Empfangsteil zu schalten, kann diese Betriebsart der visuellen FS-Kanal-Kontrolle in Anlehnung an die im FS-Studio betriebenen üblichen Kontrollvorgänge, als Monitor-Betrieb bezeichnet werden.The object of the invention is to provide a combined RF / FS receiver a suitable circuit arrangement, the two receivers both individually or also operate at the same time that an FS reception even during RF reception is possible. Since in this operating mode, which can be activated on request, it only makes sense is the common audio output stage with the loudspeakers connected to their output To switch to the RF receiver, this operating mode of the visual FS channel control can be used based on the usual control processes operated in the FS-Studio, as a monitor operation are designated.
Die Lösung der erfindungsgemäßen aufgabe ist in Fig. 1 in einem Blockschaltbild dargestellt und wird nachfolgend beschrieben: Mit Pos. 1 ist ein FSIEmpfangsteil ohne NF-Verstärker gekennzeichnet, dessen Tonsignal vom Ausgang des Ion-i)emodulators 2 abgegriffen und dem einen Kontakt 3a eines Umschalters 4 zugeführt wird. Die Wurzel 3c dieses Umschalters ist mit dem Eingang einer NFLeistungsendstufe 5 verbunden, an dessen Ausgang 6 ein oder mehrere Lautsprecher 7 angeschlossen sind. An dem anderen Umschaltkontakt 3b des Tonschalters 4 liegt der Demodulatorausgang des RF-Empfängers 8, der ebenfalls keine eigene Tonendstufe besitzt. Während die kontinuierliche Durchstimmung des Rundfunkempfangsteiles 8 über einen Abstimmknopf 9 erfolgt, lassen sich die in bekannterweise einprogrammierten RF- und FS-Empfangskanäle durch die, im für RF und FS-Betrieb gemeinsamen Bedienfeld 10 angeordneten Tasten oder Berührungssensoren, über die Ansteuerleitungen il und 12 zu den jeweiligen Abstimmeitheiten der beiden Empfangsteile abrufen. Verbunden mit diesem in der Schaltungseinheit 13 decodierten Abruf ist die Aktivierung der Stromversorgung an den jeweiligen Anschlüssen 14 und 15 des gemeinsamen Netzteiles 24. Das Einschalten des Gerätes und das Bereitstellen der gewinschten Betriebsart sowie das Aktivieren eines bestimmten E;npfangskanals läßt sich in bekannter Weise auch über eine drahtlose Infrarot- oder Ultraschall-Fernbedienung vornehmen. Dabei können vom Fernbediengeber 16 abgegebene Signale einen beliebigen Code aufweisen, da bei derartigen Geräte-Konzeptionen ein angepaßter Fernbedienempfänger 17 dafür sorgt, daß die in den Schaltungsgruppen 10 und 16 manuell ausgelösten Schaltungsvorgänge in der Schalteinheit 13 dieselben Signal strukturen erhalten und somit apparativ dieselben Befehle auslösen. Die Bildung von Schaltbefehlen ist in dieser Schalteinheit 13 so organisiert, daß bei nur eingeschaltetem FS-Empfänger über eine entsprechend gekennzeichnete Taste 21 die Betriebsstromversorgung nur an den Anschluß 14 und der Tonschalter 4 in die Schaltung 3a - 3c geschaltet wird, und bei nur eingeschaltetem RF-Emofänger über eine ebenfalls gekennzeichnete 2. Taste 22 die Betriebsstromversorgung nur an den Anschluß 15 und der Tonschalter in die Stellung 3b - 3c geschaltet ist.The solution to the problem according to the invention is shown in FIG. 1 in a block diagram and is described below: Pos. 1 is an FSI receiving part marked without LF amplifier, whose audio signal comes from the output of the Ion-i) emodulator 2 is tapped and one contact 3a of a changeover switch 4 is supplied. The root 3c of this switch is connected to the input of an NF power output stage 5, one or more loudspeakers 7 are connected to the output 6 thereof. On the other Changeover contact 3b of the tone switch 4 is the demodulator output of the RF receiver 8, which also does not have its own output stage. During the continuous tuning of the radio receiving part 8 takes place via a tuning button 9, the in known programmed RF and FS reception channels through the, im for RF and FS operation common control panel 10 arranged buttons or touch sensors, Via the control lines il and 12 to the respective coordination units of the two Retrieve receiving parts. Connected to this in the circuit unit 13 decoded The activation of the power supply at the respective connections 14 and is called up 15 of the common power supply unit 24. Switching on the device and making it available the desired operating mode and that Activate a specific Receiving channel can also be used in a known manner via a wireless infrared or use ultrasonic remote control. In this case, the remote control transmitter 16 can deliver Signals have any code, since such device concepts are a adapted remote control receiver 17 ensures that the in the circuit groups 10 and 16 manually triggered switching processes in the switching unit 13 are the same Receive signal structures and thus trigger the same commands in terms of equipment. The education of switching commands is organized in this switching unit 13 so that when only switched on FS receiver controls the operating power supply via a correspondingly labeled button 21 connected only to the connection 14 and the sound switch 4 in the circuit 3a - 3c , and if the RF receiver is only switched on via a also marked 2. Key 22 the operating power supply only to connection 15 and the sound switch is switched to position 3b - 3c.
Die Stromversorgung der Tonendstufe 5 ist, nach Schließen des Hauptnetzschalters 18, unabhängig von der gewählten Betriebsart über die leitende Verbindung der Anschlußpunkt 19-20 stets eingeschaltet.The power supply of the audio output stage 5 is after closing the main power switch 18, regardless of the selected operating mode via the conductive connection of the connection point 19-20 always on.
Um die erfindungsgemäße Betriebsart des Monitorbetriebes zu erreichen, müssen beide Tasten 21 und 22 entweder am Geräte-Bedienfeld 10 oder am Fernbediengeber 16 eingeschaltet werden. Die Schalteinheit 13 reagiert'auf diese Tastenstellung in der Weise, daß i.) an sämtlichen Stromversorgungsanschlüssen 14, 15 und 19 die auch im Einzelbetrieb erforderliche Betriebsspannung erscheint, 2.) der Tonschalter 4 in die Stellung 3c - 3b geschaltet wird und 3.) die freizügige Auswahl der Empfangskanäle für RF und FS durch die Programmspeicher-Tasten 23 erhalten bleibt.To achieve the monitor mode according to the invention, Both buttons 21 and 22 must either be on the device control panel 10 or on the remote control transmitter 16 can be switched on. The switching unit 13 reacts to this key position in such a way that i.) on all power supply connections 14, 15 and 19 the The operating voltage required also in individual operation appears, 2.) the tone switch 4 is switched to position 3c - 3b and 3.) the free selection of the receiving channels for RF and FS through the program memory buttons 23 is retained.
Damit können während des Empfangs und der Ton-Wiedergabe-von Rundfunksendungen auch mit der Betätigung eine der Tasten 23 jeweils wechselnde FS-Stationen auf das Bild geschaltet werden, so daß ohne akustische Unterbrechung der zuvor ausge.ählten Rundfunksendung Inhalte, Beginn- oder Endzeiten von FS-Sendungen beobachtet werden können.This can be used during the reception and the sound reproduction of radio broadcasts also with the actuation of one of the buttons 23 each changing FS stations on the Picture can be switched so that the previously selected Broadcasting content, start or end times of FS broadcasts can be observed can.
Da bei direktem Interesse an einer zu Monitor-Betrieb angetasteten FS-Sendung der Wunsch auftreten könnte, auch den zugehörigen Ton abzuhören, kann in einer Weiterführung der erfinderischen Idee, an geeigneter Stelle in den Bedienfeldern der Bedieneinheit 10 und 16 eine weitere Taste 22 angebracht werden, mit deren Be tätigung ausschließlich der Tonschalter 4 beliebig umgeschaltet werden kann. Zur Steigerung des Bedienungskomforts können sämtliche Tastenstellungen durch Farb- oder Schriftsymbole, ggfls.Since touched with direct interest in a monitor operation FS broadcast the desire to listen to the associated sound may arise in a continuation of the inventive idea, at a suitable point in the control panels the control unit 10 and 16 another button 22 are attached, with the Be operation, only the tone switch 4 can be switched at will. To the All key positions can be enhanced by color coding to increase the ease of use. or font symbols, if necessary.
