Abstract

According to the invention, the scanned levels of a prediction error matrix are sorted in accordance with a particularly advantageous sorting method, before entropic encoding, such that the values of the levels constantly decrease uniformly and so as to enable to obtain a more efficient coding. For a corresponding decoding, a sorting information is produced and likewise transmitted in entropically coded form.
