Process for transmitting and/or storing digital signals from several channels

Abstract

(57) The method for transmitting and/or memorizing the digital signal of a summary multi-channel is indicated. Especially this method is suitable for transmission of transmission of five channels of 3 / 2 solid sound, two stereo channels, and three additional commentary channels. Thus, it is possible to, transmit the TV program which has a multilingual audio signal for example. This method is distinguished from others by reduction of the data transmitted in that only 384 kbits/s bit rate is only needed for transmission. K input channels are segments and reduction of data is imaged by the NK piece virtual spectrum data channel, A spectrum data channel is quantized taking the principle of mental acoustics into consideration, It is coded and transmitted and is attained by K output channels' borrowing the help of the list too transmitted from the NK piece spectrum data channel, and being reproduced from the transmitted bit stream.
