A method of 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 and at least one N block corresponding to differences between a digital N image and at least one other image including analyzing the flow of sequences to generate a first modified flow having a format of a nominal flow and having modified N blocks and a second flow of any format including digital information required to reconstruct the modified blocks; and transmitting the first and second flows from a server to destination equipment, and calculating on the destination equipment a synthesis of a flow in a nominal format as a function of the first flow and the second flow.
