Claims (2)

1. Automatische Radiofrequenzsignal-(RF-)Schaltvorrich­ tung mit einer Mehrzahl von AV-Eingangsanschlüssen, an die ein analoger elektronischer Schalter (D) angeschlos­ sen ist,
einem A/D-Adapter (C) eines integrierten Schaltkreises mit mehreren Umsetzern, deren jeder an einen Ausgangs­ anschluß des Videosignals der mehreren AV-Eingänge an­ geschlossen ist und die analogen Videosignale in digita­ le Signale umsetzt,
einem Zentralprozessor (F), von dem ein Ausgang an den analogen elektronischen Schalter (D) angeschlossen ist, einem RF-Schalter (H), einem Antenne-/Kabel-RF-Schalter (I) und einer LED-Anzeige (G),
wobei die Videosignale der mehreren AV-Eingänge in hoch­ pegelige Spannungssignale transformiert werden und auf einen Eingang des Zentralprozessors (F) gegeben werden, welcher seinerseits ein Spannungssignal erzeugt für den analogen elektronischen Schalter (D), einen RF-Modulator (E) und den RF-Schalter (H), um die AV-Signale mit Prio­ rität über den analogen elektronischen Schalter (D), den RF-Modulator (E) und den RF-Schalter (H) einem Fernseh­ gerät (L) zuzuführen,
wobei der Zentralprozessor (F) gleichzeitig ein Span­ nungssignal zur Abschaltung des Antenne-/Kabel-RF-Schal­ ters (I) erzeugt und die RF-Signale interferenzfrei dem Fernseher (L) zugeführt werden und wobei die LED-Anzeige (G) den Betrieb des AV-Geräts anzeigt;
während beim Ausbleiben eines AV-Signals der Zentral­ prozessor (F) einen anderen Satz von Spannungssignalen hohen Pegels einem Antenne-/Kabel-RF-Verstärker (J) so­ wie dem RF-Schalter (H) zuführt und dadurch automatisch die Umschaltung der Speisung des Fernsehers (L) auf die Antenne-/Kabelsignale bewirkt, die eine entsprechende LED-Anzeige (G) auslöst.1. Automatic radio frequency signal (RF) switching device with a plurality of AV input connections, to which an analog electronic switch (D) is connected,
an A / D adapter (C) of an integrated circuit with several converters, each of which is connected to an output connection of the video signal of the several AV inputs and converts the analog video signals into digital signals,
a central processor (F), from which an output is connected to the analog electronic switch (D), an RF switch (H), an antenna / cable RF switch (I) and an LED display (G),
wherein the video signals of the multiple AV inputs are transformed into high-level voltage signals and are applied to an input of the central processor (F), which in turn generates a voltage signal for the analog electronic switch (D), an RF modulator (E) and the RF Switch (H) to feed the AV signals with priority via the analog electronic switch (D), the RF modulator (E) and the RF switch (H) to a television (L),
wherein the central processor (F) simultaneously generates a voltage signal for switching off the antenna / cable RF switch (I) and the RF signals are fed interference-free to the television (L) and the LED display (G) is used for operation of the AV device;
while in the absence of an AV signal, the central processor (F) supplies another set of high-level voltage signals to an antenna / cable RF amplifier (J) such as the RF switch (H), thereby automatically switching the supply of the TV (L) on the antenna / cable signals, which triggers a corresponding LED display (G). 2. Automatische Schaltvorrichtung nach Anspruch 1, in der der Analog-Digital-Adapter (C) ein integrierter Schaltkreis mit mehreren Konvertern ist, die die ankom­ menden Videosignale in digitale Form transformieren, wobei beim Einschalten eines angeschlossenen AV-Geräts durch den Benutzer ein Ausgangsanschluß eines der Kon­ verter ein das Eintreffen von AV-Signalen am Analog/­ Digital-Adapter (C) anzeigendes hohes Spannungssignal erzeugt und einem Eingangsanschluß des Zentralprozessors (F) zuführt, welcher aus dem signalbeaufschlagten Ein­ gangsanschluß erkennt, welches AV-Gerät aktiviert ist, und die zeitliche Reihenfolge der Aktivierung der AV- Ausrüstung in einer Speichereinheit des Zentralprozes­ sors speichert, während nichtbeaufschlagte Eingangsan­ schlüsse erkannt werden und ohne Berücksichtigung blei­ ben und nur die vom empfangenen Eingangssignal betroffe­ nen Teile betreut werden.2. Automatic switching device according to claim 1, in an integrated analog-digital adapter (C) Circuit with multiple converters, which the incoming transforming video signals into digital form, being when turning on a connected AV device by the user an output port of one of the con the arrival of AV signals on the analog / High voltage signal indicating digital adapter (C) generated and an input port of the central processor (F) feeds which from the signal-loaded on connection recognizes which AV device is activated, and the chronological order of activation of the AV Equipment in a central processing unit sors stores while unloaded input conclusions are recognized and without considering lead ben and only those affected by the received input signal parts are looked after.
