Abstract

Audio data from a useful signal source (1) are separated (2) into a main data stream (HD) and an auxiliary data stream (ZD). The main data stream (HD) contains at least the amount of information that is required for a comprehensive reproduction of at least one useful signal source (1). Main- and auxiliary data stream are transmitted in different channels (K1, K2) within a predetermined channel raster.

It is possible to increase the reproduction quality of the audio signal within a predetermined channel raster.
