Abstract (en)
[origin: WO2007009996A1] The invention relates to a method for filtering a scalable video stream, organised in the form of data unit blocks, each of which comprises a base data unit and a set of data units distributed according to two types of enhancement data, corresponding respectively to time and/or space and/or quality characteristics and making it possible to define several quality levels. The inventive method consists in defining at least two distinct filtering profiles, or paths of each block data units, wherein each path defines a row of successive foldover positions and each foldover position uses at least by one less data units than a previous position, and in selecting one of said paths according to a predetermined criterion, taking into account the type of content of said stream and/or at least one information item representing the capacities of a terminal receiving said stream.
