Abstract
A method for distributing video sequences according to a nominal flow format including a succession of frames, each including at least one I block corresponding to a complete digital I image, each I image being broken down into blocks and macroblocks dependent on each other by correlation coefficients, including: analyzing a flow of sequences; generating a first modified flow having a format of a nominal flow and having I images modified by substitution of selected correlation coefficients by coefficients of the same type, but being random, and a second flow of any format including the substituted correlation coefficients and digital information which can enable reconstruction of the modified images; transmitting the first and second modified flows from a server to destination equipment; and calculating on the destination equipment a synthesis of a flow of the nominal format as a function of the first and second flows.
