Abstract
A method for processing a digital file of the images, video and/or audio type which comprises a phase for putting into line per color layer and/or per audio channel, digital data of any audio, image and video file, a compression phase using algorithm in which each compressed value VCn of position N is obtained by subtracting from the value Vn of same position N of the original file, a predetermined number of successive compressed values (VCn-1, VCn-2, . . . ) calculated previously, and a restoration phase using an algorithm in which each restored value VDn of position N is obtained by adding to the value VCn, of the same position of the compressed file, a predetermined number of successive compressed values (VCn-1, VCn-2, . . . ).
