Description
Die Erfindung betrifft ein Verfahren zur Anpassung einer Rundfunkempfangsantenne an eine Empfangssituation.The The invention relates to a method for adapting a broadcast receiving antenna to a reception situation.

sind im Stand der Technik, beispielsweise aus der
Erfahrungen aus der Praxis haben jedoch gezeigt, dass die Vorverstärkung des Antennensignals nicht grundsätzlich eine bessere Signalqualität bzw. eine geringere BER zur Folge hat. Im Gegenteil liefert in vielen Empfangssituationen die passive Betriebsart eine geringere BER und somit eine bessere Empfangsqualität.experience from practice, however, have shown that the preamplification the antenna signal is not fundamentally a better signal quality or results in a lower BER. On the contrary, in many Receiving situations, the passive mode of operation is a lower BER and thus a better reception quality.
Im Stand der Technik ist daher der Nachteil zu verzeichnen, dass viele Benutzer digitaler Rundfunkempfänger nicht wissen, in welchen Fällen die aktive und in welchen Fällen die passive Betriebsart ihrer Antenne eine bessere Empfangsqualität erzielt. Insbesondere sind für den Empfang verschiedener Kanäle oft verschiedene Betriebsarten sinnvoll. Außerdem besitzen die meisten Benutzer bereits einen Rundfunkempfänger, den sie weiterhin verwenden möchten. Vor diesem Hintergrund mangelt es diesbezüglich an einer kostengünstigen Lösung mit einem möglichst hohen Bedienkomfort.in the The prior art is therefore the disadvantage that many Users of digital radio receivers do not know in which Cases the active and in which cases the passive one Operating mode of their antenna better reception quality achieved. In particular, for the reception of different channels often different operating modes make sense. Also own Most users already have a radio receiver, the you want to continue using it. Against this background lacks a cost-effective in this respect Solution with the highest possible ease of use.
Der Erfindung liegt somit die Aufgabe zugrunde, einen Rundfunkempfänger ohne zusätzlichen Hardwareaufwand zur automatischen Optimierung der Betriebsart (aktiv/passiv) einer signalweggespeisten aktivschaltbaren Antenne, welche ihre Betriebsart vom Vorhandensein einer Betriebsspannung abhängig macht, zu befähigen. Diese Lösung soll auch als Softwareupdate für bereits auf dem Markt befindliche Rundfunkempfänger verwendbar sein.Of the Invention is therefore the object of a radio receiver without additional hardware costs for automatic optimization the operating mode (active / passive) of a signal-path-fed active switchable Antenna indicating its mode of operation from the presence of an operating voltage dependent to empower. This solution should also as a software update for already on the market Radio receiver be usable.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des unabhängigen Anspruchs 1 gelöst.These Task is performed by a procedure with the characteristics of the independent Claim 1 solved.
Das Wesen der Erfindung besteht in einem Verfahren zur Anpassung einer Rundfunkempfangsantenne an eine Empfangssituation, wobei ein über eine Signalleitung an den Signaleingang der Rundfunkempfangsantenne angeschlossener Rundfunkempfänger die Rundfunkempfangsantenne durch Anlegen bzw. Nichtanlegen einer Betriebsspannung an die Signalleitung in die aktive bzw. in die passive Betriebsart schaltet und dadurch sowohl zu deren aktiver als auch zu deren passiver Betriebsart jeweils mindestens eine signifikante Größe bestimmt, mit deren Hilfe er diejenige Betriebsart, welche eine bessere Empfangsqualität aufweist, als sogenannte „optimale Betriebsart” ermittelt und die Rundfunkempfangsantenne daraufhin zum Empfangsbetrieb in diese optimale Betriebsart schaltet.The essence of the invention consists in a method for adapting a radio receiving antenna to a receiving situation, wherein a via a signal line to the signal input of the radio receiving antenna connected radio receiver switches the radio receiving antenna by applying or not applying an operating voltage to the signal line in the active or in the passive mode and thereby determines at least one significant variable both with respect to its active mode and its passive mode of operation, with de Help he the one operating mode, which has a better reception quality, as the so-called "optimal mode" determined and the radio receiving antenna then switches to receiving mode in this optimal mode.
Dem Benutzer wird so ein Verfahren zur Verfügung gestellt, mit dem die Auswahl einer bezüglich der Empfangsqualität optimalen Betriebsart der Antenne für jede Empfangssituation ohne zusätzlichen Bedienaufwand gewährleistet ist.the User is provided with such a procedure with the selection of one regarding the reception quality optimal mode of operation of the antenna for each reception situation guaranteed without additional operating effort is.
Dieses Verfahren besitzt gegenüber dem Stand der Technik den Vorteil, dass jeder moderne und bereits auf dem Markt befindliche Rundfunkempfänger, der eine über seine Gerätesoftware auf einen Signaleingang aufschaltbare Speisung für den Betrieb einer signalweggespeisten aktiven Antenne besitzt, mit einem Softwareupdate zu der erfindungsgemäßen Lösung befähigt werden kann.This Method has the advantage over the prior art, that any modern radio receiver already on the market, the one via its device software to a signal input switchable power supply for the operation of a signal path fed active antenna, with a software update to the invention Solution can be enabled.
Das erfindungsgemäße Verfahren ist kostengünstig, da es außer dem vorgenannten Rundfunkempfänger, keine zusätzliche Hardware benötigt.The inventive method is inexpensive, since, in addition to the aforementioned radio receiver, no additional hardware needed.
In einer vorteilhaften Ausführung kann der Rundfunkempfänger mehrere verschiedene Empfangskanäle empfangen und ermittelt für jeden dieser Empfangskanäle jeweils die optimale Betriebsart. Diese jeweils ermittelte Betriebsart speichert der Rundfunkempfänger als dem entsprechenden Empfangskanal zugehörig. Beim Aufruf eines solchen Empfangskanals kann der Rundfunkempfänger die Antenne sofort in die für diesen Empfangskanal optimale Betriebsart schalten.In an advantageous embodiment of the radio receiver received and detected several different receive channels for each of these receiving channels each the optimal Mode. This respectively determined mode stores the radio receiver as belonging to the corresponding receiving channel. When calling such a receiving channel, the radio receiver The antenna immediately in the optimal for this receiving channel Switch operating mode.
Weitere vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are in the subclaims characterized.
Im Folgenden soll ein bevorzugtes Ausführungsbeispiel die Erfindung anhand einer Zeichnung näher erläutern.in the Below is a preferred embodiment of the Explain the invention with reference to a drawing.
Zunächst wird die Antennenspeisung eingeschaltet. Die angeschlossene Antenne nimmt daraufhin die aktive Betriebsart an.First the antenna feed is switched on. The connected antenna then accepts the active mode.
Im nächsten Schritt bestimmt der Rundfunkempfänger aus dem digitalen Signal eine erste Bitfehlerrate BER1.in the The next step is determined by the radio receiver from the digital signal, a first bit error rate BER1.
Dann wird die Antennenspeisung ausgeschaltet. Die Antenne nimmt daraufhin die passive Betriebsart an.Then the antenna feed is switched off. The antenna picks up the passive mode.
Im darauf folgenden Schritt bestimmt der Rundfunkempfänger aus dem digitalen Signal eine zweite Bitfehlerrate BER2.in the the next step is determined by the radio receiver from the digital signal, a second bit error rate BER2.
Nun werden die beiden Bitfehlerraten miteinander verglichen.Now the two bit error rates are compared.
Die Betriebsart mit der geringeren Bitfehlerrate wird verwendet.The Operating mode with the lower bit error rate is used.
