filtering processes, transmission of scalable video stream reception, signal, programs, server, intermediate node and the corresponding terminal

The invention relates to a method of filtering a scalable video stream, organized into blocks of data units each comprising a database unit and a set of enhancement data units distributed in at least two types of data enhancement respectively corresponding to time characteristics and / or spatial and / or quality, and to define various quality levels, comprising a step of defining at least two profiles, or paths, separate data units filtering of each block, each path defining a series of successive withdrawal positions, each fallback position using at least one data unit less than the preceding position, and a step of selecting one of said paths based on a predetermined criterion taking into account a content type of said flow and / or at least one information representative of terminal capabilities receiving said flow.
