Abstract
The description relates to a process for the simultaneous transmission of signals from N signal sources via a corresponding number of transmission channels, by which the individual signals are divided into frames and the frames are converted into spectral coefficients by transformation or filtering, said spectral coefficients being subjected to a data reduction process. The invention is characterized by the fact that the frames belonging to the individual signals are divided into sections, the current sections of all signals are processes together, the permitted fault for each section is determined by using a perception-specific model, the allocation to the maximum available transmission capacity is calculated for each individual signal from the total transmission capacity available and the currently required total transmission capacity, and each individual signal is encoded and transmitted at the capacity determined in this way.
