Abstract (en)
[origin: EP1499158A2] The system has an audio signal generator (S,VCR), a data generator (S,A) for control and/or test data generation, a mixer (M) for mixing the audio signal and data before common reproduction, at least one loudspeaker (L1-L5), a sound signal receiver (MIC,C) and a receiver-side data processing device (C) for processing data in the sound signal and triggering corresponding actions. The data processing device with receiver forms a data return channel for the data with a device before the loudspeaker for control and/or monitoring. Independent claims are also included for the following: (a) a method of reproducing at least one audio signal; and (b) a surround- sound signal using components of a system according to the invention.
