ABSTRACT:
For the purpose of transmitting digital audio signals from recording studios to the various broadcasting stations of a broadcasting network, the data flow of the digital audio signals to be transmitted is initially reduced in accordance with a technique which utilizes the psychoacoustic phenomena of the human ear. Then groups of these data-reduced digital audio signals are respectively encoded in a baseband in accordance with a DS1-technique and combined to form respective DS1/M-signals. Finally, the thus produced DS1/M-signals are transmitted in accordance with the DSR technique by use of a wide-band transmission system to the individual broadcasting stations of the broadcasting network.
