A process for differential coding of a motion vector associated with a macro-block, including the steps: of determining the components of the said motion vector, of determining a prediction vector, each component of which is equal to the median value of the corresponding components of at least three candidate motion vectors, a candidate motion vector being a vector associated with a previously coded macro-block, and of subtracting the components thus obtained from the components of the vector to be coded. Implementation of the process is included.
