Abstract

The data transmission system has a digital interface allowing a number of electronic devices to be coupled to a central control point (13) which incorporates a reception device (12) for remote control signals provided by a hand held remote control device (11). Pref. the central control point has a preamplifier for audio signals which are fed to active loudspeaker boxes (5,6) receiving the remote control signals for adjusting the volume, the balance, the resonance, or tone etc. The remote control data may be fed to the loudspeaker boxes from the central control point via optical fibre coupling paths. USE - Remote control of stereo system.

Description

Die Erfindung betrifft ein Übertragungssystem für Daten zur Steuerung fernbedienbarer elektronischer Geräte, die eine digi­ tale Schnittstelle nach AES-Norm besitzen. Eine derartige Schnittstelle gibt es z. B. bei Audioanlagen zur Wiedergabe digital gespeicherter Musikprogramme. Die Schnittstelle über­ trägt neben den Daten für die eigentliche Audio-Information mit Hilfe der Datenbits auch weitere Informationen über den soge­ nannten U-Bit-Kanal z. B. über die Nummer des wiedergegebenen Stücks, dessen Zeitdauer usw.The invention relates to a transmission system for data Control of remote-controlled electronic devices that have a digi have a tal interface according to the AES standard. Such one There is an interface z. B. in audio systems for playback digitally stored music programs. The interface over contributes along with the data for the actual audio information With the help of the data bits also further information about the so-called called U-bit channel z. B. on the number of the reproduced Piece, its duration, etc.

Bei digitalen Audioanlagen werden zunehmend Aktiv-Boxen einge­ setzt, bei denen die Endverstärker mit diesen integriert sind. Auch die Digital-Analog-Wandlung wird innerhalb der Boxen vorge­ nommen. Bei der Fernsteuerung derartiger Anlagen müssen die Stellglieder, z. B. für Lautstärke, Klang, Balance sowie das Ein- und Ausschalten der Verstärker gleichmäßig betätigt wer­ den. Je nachdem wie die Aktiv-Boxen plaziert sind, stößt dies oftmals auf Schwierigkeiten, da die Fernsteuersignale diese nicht in gleicher Weise erreichen.Active boxes are increasingly being used in digital audio systems sets in which the power amplifiers are integrated with them. The digital-to-analog conversion is also featured within the boxes taken. In the remote control of such systems, the Actuators, e.g. B. for volume, sound, balance and that  Switching the amplifier on and off evenly operated the. Depending on how the active boxes are placed, this comes across often on difficulties because the remote control signals this not achieve in the same way.

Der Erfindung liegt die Aufgabe zugrunde, die Fernbedienbarkeit akustischer Anlagen zu verbessern. Diese Aufgabe wird durch die im Patentanspruch angegebene Maßnahme gelöst.The invention is based, remote control improve acoustic systems. This task is accomplished by the measure specified in the claim solved.

Nachstehend wird die Erfindung an einem Ausführungsbeispiel mit Hilfe der Zeichnung erläutert.The invention is based on an embodiment with Help explained in the drawing.

Mit 1 ist ein Vorverstärker gekennzeichnet, der die z. B. von einem Abspielgerät 2 erzeugten digitalen Audiosignale ver­ stärkt, die über Datenleitungen 3 und 4 an Aktiv-Boxen 5 und 6 weitergeleitet werden. In den Aktiv-Boxen befindet sich die Digital-Analog-Wandler 7 und 8 sowie die Endverstärker 9 und 10. Mit Hilfe einer Fernsteuerung 11, deren Signale von einem Fernsteuersignalempfänger 12 verarbeitet werden, können die Aktiv-Boxen 5 bzw. 6 ein- und ausgeschaltet werden und das Klangbild wie Höhen, Tiefen, Balance und Lautstärke kann eben­ falls fernbedienbar verändert werden. Hierzu wird der in der AES-Norm vorgesehene U-Kanal verwendet, über welche die Steuer­ daten für die Aktiv-Boxen übertragen werden. Auf diese Weise können die Fernbedienungssignale störungsfrei und insbesondere gleichzeitig bzw. gleichmäßig an die Aktiv-Boxen herangeführt werden, weil die Fernbedienung nur noch mit einer einzigen Einheit, der Steuereinheit 13, korrespondieren muß, die dann die Steuersignale gleichmäßig umsetzt. 1 with a preamplifier is marked, the z. B. from a playback device 2 generated digital audio signals ver, which are forwarded via data lines 3 and 4 to active boxes 5 and 6 . The digital boxes 7 and 8 and the power amplifiers 9 and 10 are located in the active boxes. With the help of a remote control 11 , the signals of which are processed by a remote control signal receiver 12 , the active boxes 5 and 6 can be switched on and off and the sound image such as highs, lows, balance and volume can also be changed by remote control. For this purpose, the U-channel provided in the AES standard is used, via which the control data for the active boxes are transmitted. In this way, the remote control signals can be brought to the active boxes without interference and in particular simultaneously or evenly, because the remote control only has to correspond to a single unit, the control unit 13 , which then converts the control signals evenly.
