Method and system for sending user data from an encoder to a decoder vu00ecdeo vu00ecdeo, method and device for inserting user data into a signal of vu00ecdeo encoded.Method and device for recovering user data inserted in a given position in a sign of vu00ecdeo encoded, vu00ecdeo encoder to encode a signal vu00ecdeo,Vu00ecdeo decoder to decode a signal vu00ecdeo vu00ecdeo, signal, and computer program.The invention relates to a method and a device for sending user data of a video encoder and a video decoder.The user data is inserted in the video signal generated by the encoded video encoder.The method is characterized by the fact of understanding at the end of the encoder: a step of insertion (202) to insert a set of packages of filling in a given position in said signal Vu00eddeo encoded, the number of packets filling in said set being determined via a lookup table from the above user data (201).And at the end of the decoder: a step of analysis (204) to detect and count the number of packets of filling in the given position in said video signal encoded.The number of packets filling being used to derive these user data, use the search table (205).
