1. Method of coding picture sequences using a coding device, based on a 3D wavelet coding, including a coding phase which comprises: a step for determining at least one information item for configuring the 3D wavelet coding as a selection of a reference picture for a sequence of successive pictures, based on a predetermined optimizing criterion; then a step for generating a configuration information unit comprising a datum of the reference picture for the said sequence of successive pictures; and finally a step for executing the 3D wavelet coding based on the configuration information to give 3D wavelet coding data, in such a way as to produce a stream of coded data comprising the union for each sequence of pictures of a configuration information unit and of the 3D wavelet coding data for the pictures of the picture sequence.
