Multichannel sound signal transmission procedure with interference correction - using introduced time difference between transmitted signal preceded by defined phase difference used to provide matrix signals

摘要

Associated channels are supplied with signals at the transmission side exhibiting a defined time difference, the corresponding time difference between the signals compared at the reception end to allow compensation of transmission errors. A defined phase difference, independent of the frequency is provided between the input signals prior to the introduced time difference with the sum and difference values for the phase-shifted signals obtained at the transmission end, the interference sections of the matrix signal subjected to muting at the reception end. USE/ADVANTAGE - Allows transmission via channels subject to interference for digital speech or music transmission.
