Abstract
Die Erfindung bezieht sich auf ein Audiowiedergabesystem mit einer Audiosignal-Bereitstellungseinrichtung (PC,S,VCR) zum Bereitstellen eines Audiosignals (s,r), einer Datenbereitstellungseinrichtung (S,A) zum Bereitstellen von Daten (d,rd) für Steuer- und/oder Überprüfungszwecke, einer Mischeinrichtung (M) zum Zusammenmischen des Audiosignals (r) und der Daten (rd) vor deren gemeinsamer Wiedergabe,
zumindest einem Lautsprecher (L1-L5) zum Wiedergeben eines aus dem Tonsignal (r) und den Daten (rd) erzeugten akustischen Schallsignals (sw+sd), einer Empfängereinrichtung (MIC,C) zum Empfangen des Schallsignals (sw+sd) und einer empfängerseitigen Datenverarbeitungseinrichtung (PC;C) zum Verarbeiten der in dem Schallsignal (sw+sd) enthaltenen Daten (sd) und zum Auslösen dementsprechend durchzuführender Aktionen.
The invention relates to an audio reproduction system having an audio signal providing device (PC, S, VCR) for providing an audio signal (s, r), a data providing device (S, A) for providing data (d, rd) for control and / or or checking purposes, mixing means (M) for mixing together the audio signal (r) and the data (rd) before their common reproduction,
at least one loudspeaker (L1-L5) for reproducing an acoustic sound signal (sw + sd) generated from the sound signal (r) and the data (rd), a receiver device (MIC, C) for receiving the sound signal (sw + sd) and a receiver-side data processing device (PC; C) for processing the data (sd) contained in the sound signal (sw + sd) and for triggering actions to be performed accordingly.
