Description
Abstimmanzeige bei einem Fernsehgerät
Neben der Anwendung von Anzeigemitteln, vle sie aus der Rund-, funkteohnik
bekannt sind, gibt es schon eine Reihe von Lösungen, die sich der speziellen Bauelemente
der Rernsehtechnik oedienen, wie bspw. die Bildröhre selbst als Anzeigemittel zu
verwenden. Es sind auch Lösungen bekannt, die über eine Trennrohre Abstimmkreise
anschalten.
Nach der Neuerung wird die Video-Zwischenfrequenz-Durchlaßcharakteristik mittels eines oder mehrerer schaltbarer Kreise, die vornehmlich als Saugkreise ausgebildet sind und im ausgeschalteten Zustand die Form der Charakteristik nicht beeinflussen können. verformt. Durch die Anschaltung der Abstimmhilfekreise aber bekommt die Durohlaßkurve eine derartige Form, daß bei richtiger Lage des Bildträgers eine hohe Resonanzspannung auftritt, die an der vorhandenen Video-Diode gleichgerichtet und ggf. über eine weitere Diode verdoppelt zur Aussteuerung irgendeines der bekanntn Anzeigemittel dient. Es kann dabei das Magische Auge einer Rundfunk-Fernseh-Kombination für die Dauer der Anschaltung des AbstimmHilfskreises eingeschaltet sein, es können aber auch während dieser Zeit Bild-oder Zeilenamplitude so beeinflußt werden, daß die Bildröhre selbst als Anzeigemittel dient.According to the innovation, the video intermediate frequency transmission characteristic by means of one or more switchable circuits, which are primarily designed as suction circuits and do not influence the shape of the characteristic when switched off can. deformed. By connecting the tuning aid circuits, however, the Durohlaßkurve such a shape that with the correct position of the image carrier a high Resonance voltage occurs, which is rectified at the existing video diode and possibly doubled via another diode to control any of the known Display means is used. It can be the magic eye of a radio-television combination be switched on for the duration of the connection of the auxiliary tuning circuit, it can but also during this time the image or line amplitude can be influenced in such a way that the picture tube itself serves as a display means.
Die Abbildung a) zeigt eine Anordnung gemäß der Neuerung.Figure a) shows an arrangement according to the innovation.
(1) stellt den Zwisohenfrequenz-Verstärker des Fernseh-Gerätes dar. An einer oder mehreren Stufen dieses Zwischenfrequenz-Verstärker wird/werden über einen Schalter (6) Saugkreis/Saugkreise zur Verformung der Durchlaßcharakteristik angeschaltet. Mechanisch gekoppelt mit Schalter (6) ist ein Schalter (7) e der im Video-Gleichrichter (2) die bei der Soharfabstimmung entstehende Gleichspannung abgreift und, ggf. über eine Spannungsverdopplerstufe verdoppelt, dem Anzeigemittel (4) zuführt. Im ausgeschalteten Zustand wird die Funktion des eernsehempfängeers, -Zwischenfrequenz-Stufen (1), Video-Gleiehrichter (2), Video-Endstufe (3), - durch die ansohaltbare Abstimmungshilfe nicht beeinflußt. Der Schalter (6) ist vorteilhaft so eingefügt. daß nur kalte, also keine hochfrequenzführenden * Elemente geschaltet werden.(1) represents the intermediate frequency amplifier of the television set. At one or more stages of this intermediate frequency amplifier will / will be over a switch (6) suction circuit / suction circuits for deforming the transmission characteristic turned on. Mechanically coupled to switch (6) is a switch (7) of the im Video rectifier (2) the direct voltage produced during the soaring taps off and, if necessary doubled via a voltage doubler stage, the display means (4) feeds. When switched off, the function of the television receiver, - Intermediate frequency stages (1), video rectifier (2), video output stage (3), - through does not affect the voting aid that can be stopped. The switch (6) is advantageous so inserted. that only cold, i.e. no high-frequency * elements switched will.
Die Abbildung b) zeigt die Veränderung der normalen Durchlaßkurve durch die Anschaltung der Abstimmungs-Hilfskreise.Figure b) shows the change in the normal transmission curve by connecting the voting auxiliary circuits.
