Claim 16:
17. The apparatus according to claim 10, wherein the apparatus is configured for coding the pictures into the data stream in units of portions, each of the portions being associated with a spatial region of the pictures, wherein the residual transform signal comprises, for each of the portions of the picture, a plurality of spectral components, and wherein the apparatus is configured for:
deriving the buffered transform signal from the further residual transform signal by selecting, for the buffered transform signal, a subset of spectral components of one or more portions of the previous picture, and
deriving the residual transform signal of the picture by predicting spectral components of one of the portions of the transform signal using corresponding spectral components of a corresponding portion of the buffered transform signal-.
