The invention relates to a method and device for sending a user data from a video encoder to a video decoder, the user data being inserted in the coded video signal generated by said video encoder. The method is characterized in that it comprises at the encoder end: an insertion step of inserting a set of stuffing packets at a given position in said coded video signal, the number of stuffing packets in said set being determined via a look-up table from said user data, and at the decoder end: an analysis step of detecting and counting the number of stuffing packets at said given position in said coded video signal, said number of stuffing packets being used for deriving said user data via said look-up table. |
