Abrégé
(EN)
A network node (124) includes an input module operable to receive an original scalable bit stream (126) having an original bandwidth range, a transcaling module operable to generate a new scalable bit stream (128) having a new bandwidth range, wherein the new bandwidth range corresponds to a range of bandwidth that is different from that of the original bandwidth range, and an output module operable to transmit said new scalable bit stream (128) downstream.
(FR)
Aux fins de l'invention, un noeud de réseau (124) comprend: un module d'entrée capable de recevoir un flux binaire initial aux dimensions modifiables (126), à gamme initiale en largeur de bande; un module de transformation d'échelle capable de fournir un nouveau flux binaire aux dimensions modifiables (128), à nouvelle gamme en largeur de bande, sachant que la nouvelle gamme en largeur de bande est différente de la gamme initiale; et un module de sortie capable de transmettre le nouveau flux (128) en question vers l'aval.
