Abstract

L'invention concerne un procédé et des dispositifs permettant l'incorporation d'un filigrane. Un tel procédé consiste par exemple à identifier une ou plusieurs trames associées à un flot (240) de données numériques compressées, et à dégrouper une ou plusieurs trames afin de définir une pluralité d'ensembles (320) de coefficients de transformation, puis à modifier cette pluralité d'ensembles (320) de coefficients de transformation pour incorporer le filigrane (230).
