In a method for reducing data in a multi-channel data transmission, existing cross-relations between the signal channels are determined with due consideration of the transit-time difference. Upon the data transmission, a signal channel, the predictor coefficients and transit-time differences obtained from the cross-relations ascertained, and the prediction error are transmitted. At the receiver, the signal of the second channel is reconstructed from the transmitted signal channel, the predictor coefficients, the transit-time difference, and the prediction error. In this way, the amount of data to be transmitted in the case of multi-channel video or audio signals is reduced.
