Abstract

The volume controller imitates the volume control signal codes of the existing remote controller. The actual sound level can be adjusted to a desired sound level without interfering with an apparatus, such as a television apparatus. The volume controller is an additional remote controller and measures the existing sound level using a microphone. The codes for existing remote controllers can be programmed and the volume controller can be integrated in existing remote controllers.

Description

1. Technisches Gebiet1. Technical field Elektrotechnik, Klang- und LautstärkeregelungElectrical engineering, sound and volume control 2. Stand der Technik2. State of the art

Manuelle Fernbedienung von Video- und Audiogeräten mittels Infrarot. Insbesondere manuelle Lautstärkeregelung. Entsprechende Geräte sind im Lieferumfang neuer TV-Geräte enthalten, bzw. werden über den Elektronikhandel (z. B. Conrad-Katalog 1996) als Ersatzgeräte angeboten. Diese Geräte können die Lautstärke ihres Wiedergabegerätes ausschließlich durch Bedienung der Laut- und Leisertaste regeln.Manual remote control of video and audio devices using Infrared. In particular manual volume control. Corresponding devices are included in the scope of delivery of new TV sets included or are available through electronics retailers (e.g. Conrad catalog 1996) offered as replacement devices. These devices can control the volume of their playback device only by operating the volume and volume down buttons regulate.

Automatische Lautstärkeregelungen gibt es beispielsweise in Autoradios zur Anpassung an den allgemeinen Geräuschpegel (DE 27 16 564) oder zur Tonabschaltung bei Telefonanrufen. In diesen Fällen wird jedoch nicht die Lautstärke bei senderbedingten Pegelunterschieden angepaßt.There are automatic volume controls, for example, in Car radios to adapt to the general noise level (DE 27 16 564) or to switch off the sound for phone calls. In these cases, however, the volume does not decrease adjusted level differences caused by the transmitter.

3. Zugrundeliegendes Problem3. Underlying problem

Fernseh- und Radiosender übertragen ihre Sendungen mit unterschiedlichem Dynamikumfang und unterschiedlicher Modulationsstärke.TV and radio stations broadcast their programs different dynamic range and different Modulation strength.

Der Hörer steht dadurch vor dem Problem, sowohl beim Senderwechsel als auch beim Programmwechsel eines einzigen Senders die Lautstärke anpassen zu müssen. The listener faces the problem, both with Changing channels as well as changing a single program Transmitter to adjust the volume.  

Ein Beispiel dafür sind Werbeblöcke und Trailer fast aller TV-Programmkanäle. Diese Programmteile werden deutlich lauter wiedergegeben als andere Sendungen. Bei Werbung soll dies die Aufmerksamkeit des Hörers erhöhen.An example of this are advertising blocks and trailers for almost everyone TV program channels. These parts of the program become clear played louder than other programs. When advertising this will increase the listener's attention.

Ein anderes Beispiel sind unterschiedlich empfundene Lautstärken beim Wechsel Musik auf Sprache. Die Sprachwiedergabe wird häufig als zu leise empfunden und die Lautstärke des Empfängers muß manuell erhöht werden. Obwohl die Sender unterschiedliche Aussteuerungen für verschiedene Programmteile veranlassen können, reicht dies in der Praxis nicht aus.Another example are perceived differently Volume levels when switching music to speech. The Voice reproduction is often perceived as too quiet and that The volume of the receiver must be increased manually. Although the transmitters have different levels of control for different ones In practice, this can be enough to initiate program parts not from.

Diese Lautstärkeschwankungen und die daraus manuelle nötig werdenden Anpassungen werden als lästig empfunden.These volume fluctuations and the resulting manual are necessary adjustments are perceived as annoying.

4. Erfindung4. Invention

4.1. Eigenständige Apparatur zur automatischen Lautstärkereglung von Bild- und Tonwiedergabegeräten mittels Infrarot-, Ultraschall- und Funkfernsteuerungen.4.1. Stand-alone equipment for automatic Volume control of image and sound reproduction devices by means of infrared, ultrasound and Radio remote controls.

Die Apparatur wird dabei in Form einer Zusatzfernbedienung realisiert. Diese mißt den vorhandenen Schallpegel mittels einem Mikrofon und paßt diesen der vorgewählten Lautstärke an. Die Anpassung geschieht durch Imitation der Signalcodes der vorhandenen Fernbedienung für lauter und leiser.The apparatus is in the form of a Additional remote control implemented. This measures the existing sound level using a microphone and adjusts this to the preselected volume. The Adaptation is done by imitating the signal codes the existing remote control for louder and quieter.

4.2. wie unter 4.1. mit dem Unterschied, daß die Apparatur Bestandteil der mitgelieferten Fernbedienung bzw. einer Ersatz- oder Zusatzfernbedienung wird. 4.2. as under 4.1. with the difference that the apparatus Part of the supplied remote control or a replacement or additional remote control.  

Sowohl 4.1. als auch 4.2. werden dadurch besonders ausgezeichnet, daß in keinem Fall ein Eingriff in das vorhandene TV- oder Audiogerät nötig ist.Both 4.1. as well as 4.2. become special excellent that no interference with the existing TV or audio equipment is necessary.

5. Gewerbliche Anwendung5. Commercial application

5.1. Vertrieb als eigenständiges Gerät, das für die Codes vorhandener Fernbedienungen programmiert werden kann bzw. diese "lernen" kann.5.1. Sales as a standalone device that codes existing remote controls can be programmed or "learn" them.

5.2. Vertrieb durch Integration in Fernbedienungen oder Ersatzfernbedienungen.5.2. Sales through integration in remote controls or Replacement remote controls.

6. Vorteilhafte Wirkungen6. Beneficial effects

Besseres Verstehen von leiser Sprache und Halten von Zimmerlautstärke bei einem Pegelanstieg des Senders. Herabregelung der Lautstärke bei höherem Zimmerpegel, wie durch laute Unterhaltung.Understand soft speech and keep speech better Room volume when the level of the transmitter rises. Decrease the volume at higher room levels, such as through loud entertainment.

7. Ausführungsbeispiel7th embodiment

Unter 4. wurde bereits ein grober Realisierungsvorschlag genannt. Die beiliegende Zeichnung verdeutlicht diesen. Der Lautstärke-Komperator vergleicht den vorhandenen Istpegel mit dem eingestellten Sollpegel. Der Sollpegel kann einfach - wie dargestellt - über ein Potentiometer gewählt werden, oder durch Tastendruck der gerade vorhandene Istpegel als Sollpegel gespeichert werden. Die Regelung wird dabei so ausgeführt, daß kurzzeitige Schwankungen oder Pausen keine Lautstärke-Nachführung bewirken. Dazu wird die Lautstärke über Zeitscheiben im Sekundenbereich integriert und das Ergebnis als Istwert herangezogen. Eine gehörrichtige Messung der Lautstärke verbessert die Regeleigenschaften. A rough implementation proposal has already been made under 4. called. The attached drawing illustrates this. The volume comparator compares the existing one Actual level with the set target level. The target level can easily - as shown - via a potentiometer can be selected, or by pressing the straight button existing actual levels can be saved as target levels. The control is carried out so that temporary Fluctuations or pauses no volume tracking cause. For this purpose, the volume over time slices in the Seconds range integrated and the result as actual value used. An accurate measurement of the volume improves the control properties.  

Die Lautstärkeregelstufe erhöht oder erniedrigt die Lautstärke durch die Informationen vom Komperator.The volume control level increases or decreases the Volume through the information from the comparator.

Weiterhin bildet sie das Interface zum Signalgenerator der Fernbedienung für laut und leiser. Einfach umschrieben funktioniert die Regelstufe parallel zu den Lautstärketasten der Fernbedienung.Furthermore, it forms the interface to the signal generator of the Remote control for loud and quiet. Simply described the control stage works in parallel to the Volume buttons on the remote control.

Zur Schonung der Batterie der Fernbedienung arbeitet die Lautstärkeregelung stromsparend und kann zusätzlich bei längeren Pegelpausen einen Stand-By-Modus aktivieren. Desweiteren muß sich die Regelung deaktivieren lassen, um gegebenenfalls die Lautstärkedynamik des Wiedergabegerätes voll ausschöpfen zu können.The works to protect the battery of the remote control Volume control saves electricity and can also be used Activate a standby mode for longer level pauses. Furthermore, the regulation must be able to be deactivated in order to if necessary, the volume dynamics of the playback device to be able to make full use of.
