Audio-Wiedergabesystem mit integrierter Funkübertragung für Audiosignale und Funkrückkanal zur Steuerung der AudioquelleAudio playback system with integrated wireless transmission for audio signals and wireless return channel for controlling the audio source

Audioquellen werden üblicherweise in der direkten Nähe eines Audio-Wiedergabegerätes installiert. Sie sind mittels einer Audioleitung direkt mit dem Wiedergabegerät verbunden. Die Bedienung erfolgt üblicherweise über eine Infrarot-Fernbedienung. Daraus ergeben sich folgende systembedingte Nachteile:Audio sources are usually installed in the immediate vicinity of an audio playback device. They are connected directly to the playback device via an audio cable. They are usually operated using an infrared remote control. This results in the following system-related disadvantages:

• Falls die Audioquelle nicht direkt neben dem Audio-Wiedergabegerät positioniert werden kann, ist ein Installationsaufwand für die Audioleitung erforderlich.• If the audio source cannot be positioned directly next to the audio playback device, an installation effort for the audio line is required.

• Die Bedienung mittels der Infrarot-Fernbedienung kann nur bei direkter Sichtverbindung zu der Audioquelle erfolgen.• The infrared remote control can only be operated if there is a direct line of sight to the audio source.

• Bei zur Zeit im Handel befindlichen Funkübertragungssystemen ist zum Anschluß eines Wiedergabegerätes (z. B. Lautsprecher, Kopfhörer) noch ein zusätzlicher Audioverstärker notwendig.• For radio transmission systems currently on the market, an additional audio amplifier is required to connect a playback device (e.g. loudspeaker, headphones).

Die erfinderische Leistung des vorliegenden Systemes besteht darin, daß die Audio-NF-Signale über eine Funkstrecke zu einem Funkempfänger übertragen werden. Dieser gibt dann die wiederhergestellten Audio-NF-Signale an einen eingebauten Verstärker, der den direkten Anschluß eines Audio-Wiedergabegerätes (z. B. Kopfhörer, Lautsprecher) ermöglicht. Dadurch ist zwischen dem Wiedergabegerät und der Audioquelle keine Kabelverbindung notwendig. Mittels der Infrarot-Fernbedienung derThe inventive achievement of the present system is that the audio NF signals are transmitted via a radio link to a radio receiver. This then passes the restored audio NF signals to a built-in amplifier, which enables the direct connection of an audio playback device (e.g. headphones, loudspeakers). This means that no cable connection is necessary between the playback device and the audio source. Using the infrared remote control of the

Audioquelle kann diese entweder direkt gesteuert werden oder mit Hilfe des im Übertragungssystem integrierten Funkrückkanals für die Infrarot-Steuersignale bedient werden. Dadurch entfällt dann auch die Notwendigkeit der direkten Sichtverbindung zwischen Fernbedienung und Infrarot-Empfänger der Audioquelle.Audio source can either be controlled directly or operated using the radio return channel for the infrared control signals integrated in the transmission system. This also eliminates the need for a direct line of sight between the remote control and the infrared receiver of the audio source.

Das von der Audioquelle (1) bereitgestellte Audiosignal wird einem Modulator (2) zugeführt. Das nun modulierte Signal wird auf den Funksender (3) gegeben. Von hier aus erfolgt die Übertragung per Funk zu dem Funkempfänger (4). Das hier empfangenen Signal wird auf den Demodulator (5) gegeben und danach zu dem Verstärker (6) geführt, an dessen Ausgang das Wiedergabegerät (7) angeschlossen ist.The audio signal provided by the audio source (1) is fed to a modulator (2). The now modulated signal is sent to the radio transmitter (3). From here, it is transmitted via radio to the radio receiver (4). The signal received here is sent to the demodulator (5) and then to the amplifier (6), to whose output the playback device (7) is connected.

Die Steuerung der Audioquelle geschieht über die Infrarot-Fernbedienung (8), deren Infrarot-Signale von dem Infrarot-Empfänger des Übertragungssystems (9) aufgefangen und umgewandelt werden. Von dort wird das Signal auf den Modulator (10) gegeben, der wiederum das Signal an den Funksender (11) weitergibt. Von hier aus wird das Signal über Funk zu dem Funkempfänger (12) übertragen. Dieser gibt das empfangene Signal auf den Demodulator (13), der wiederum das Signal auf den Infrarot-Sender (14) weitergibt. Hier wird das Fernbedienungssignal wieder als Infrarot-Signalin der ursprünglichen Form der Infrarot-Fernbedienung (8) abgestrahlt und vom Infrarot-Empfänger (15) der Audioquelle empfangen, womit die Audioquelle gesteuert wird.The audio source is controlled via the infrared remote control (8), whose infrared signals are picked up and converted by the infrared receiver of the transmission system (9). From there, the signal is sent to the modulator (10), which in turn passes the signal on to the radio transmitter (11). From here, the signal is transmitted via radio to the radio receiver (12). This passes the received signal on to the demodulator (13), which in turn passes the signal on to the infrared transmitter (14). Here, the remote control signal is again emitted as an infrared signal in the original form of the infrared remote control (8) and received by the infrared receiver (15) of the audio source, which controls the audio source.
