Abstract
The invention is a method of modifying data for obtaining a scalable video signal composed of a base video signal and a set of enhancement video signals from a non-scalable video signal. The method includes a set of attenuation steps applied to coefficients composing the non-scalable video signal, the attenuation steps being assembled in cascaded or in series for delivering the base video signal. The method further includes a re-encoding step associated with each one of said attenuation steps for delivering one of said enhancement video signals, from the coding error generated in each attenuation step.
