Способ уплотнения данных при передаче и/или накоплении цифровых сигналов нескольких зависимых каналов. Зависимость сигналов в каналах, например в левом и правом стереоканалах, может использоваться для дополнительного сокращения данных. Известные способы кодирования по методу середина - боковая сторона или способ кодирования по методу интенсивность - стерео приводят при неблагоприятной структуре сигнала к ощущаемым помехам. Способ в соответствии с изобретением избегает таких помех благодаря тому, что совместное кодирование каналов происходит только тогда, когда имеется достаточная спектральная аналогичность сигналов в обоих каналах. Кроме того, с помощью способа в соответствии с изобретением дополнительное сокращение данных может достигаться благодаря тому, что в таких частотных диапазонах, в которых спектральная энергия канала не превышает задаваемую долю общей спектральной энергии, соответствующие спектральные величины заменяются нулем. Так как способ не зависит от специфической внутренней структуры способа кодирования, он может применяться разносторонне.A method of data compression during transmission and / or accumulation of digital signals of several dependent channels. The dependence of the signals in the channels, for example, in the left and right stereo channels, can be used to further reduce data. The known methods of coding by the method of the middle - the side or the method of coding by the method of intensity - stereo lead with unfavorable structure of the signal to perceived interference. The method in accordance with the invention avoids such interference due to the fact that joint coding of the channels occurs only when there is sufficient spectral similarity of the signals in both channels. In addition, using the method in accordance with the invention, additional data reduction can be achieved due to the fact that in such frequency ranges in which the spectral energy of the channel does not exceed the specified share of the total spectral energy, the corresponding spectral values are replaced with zero. Since the method does not depend on the specific internal structure of the encoding method, it can be applied in different ways.
