ABSTRACT:
A process for distributing digital still images according to a nominal format, where each image is broken into blocks and macroblocks that depend upon each other by correlation coefficients including analyzing contents of the still images to generate two parts: a) a primary contents in nominal format corresponding to the image as modified by substitution of certain correlation coefficients with coefficients that are of the same type, but which are random, and b) additional digital nature of any format, which includes substituted correlation coefficients and digital data that are likely to allow reconstruction of the modified image; transmitting separately the modified primary contents in real or deferred time and additional digital information in real time at a moment of viewing from a server towards recipient equipment; and calculating a synthesis of contents of the recipient equipment that is in nominal format as a function of the modified primary contents and the additional data.
