Abstract: The invention relates to a method of distributing audio-visual sequences according to a nominal stream format in compliance with the MPEG-2 TS standard, said sequences comprising a succession of TS packets. The invention is characterised in that, before transmission to the client equipment, the stream is analysed in order to generate (i) a first stream with the MPEG-2 TS format, which is modified through the substitution of all or part of the constituent TS packets by packets having the same structure but with modified contents, and (ii) a second stream having any format and comprising the digital information which can be used to reconstruct the above-mentioned nominal stream. The two streams thus generated are then transmitted separately from the server to the destination equipment. The invention is further characterised in that a synthesis of a stream with the nominal format is calculated on the destination equipment as a function of said first and second streams. The invention also relates to a device for producing a video stream, a device for running a video stream and a system for transmitting a video stream in order to carry out said method.

Moreover, a synthesis of a stream with the nominal format is calculated on the destination equipment (8), for the above-mentioned stream, as a function of the first stream and the second stream. The invention is characterised in that the modification consists in modifying at least one of said motion vectors.
