Abstract  Abstract

having a transmitter and a receiver in a digital transmission system the transmitter for a wideband digital audio signal data is compressed and the compressed signal of the data is stored in the frame of the transmission signal the receiver for data expanding the compressed signals to obtain a duplicate that digital audio signal. According to the invention the transmitter is further configured to send at least a first auxiliary signal component device (6) comprises the transmitter for generating a frame of composite transmission signal the frame comprises the first frame part (FD1) containing synchronization information. comprising a data block of said data-reduced partial signal of the second frame part (FD2 FD4) and with the second frame portion of the frame after the third frame part (FD5) the third frame part comprises a data block of the auxiliary digital signal. the receiver further comprises an obtaining device (11 13) for the frame of the composite transmission signal received by a third frame part (FD5) acquiring the at least one auxiliary digital signal component.
