Claim 6:
7. The apparatus according to claim 1, wherein the pictures are coded 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, a plurality of spectral components, and wherein the apparatus is configured for:
deriving the buffered transform signal from the further transform signal by selecting and buffering a subset of spectral components of one or more portions of the previous picture, and
obtaining the transform signal of the picture by combining spectral components of one of the portions of the buffered transform signal with corresponding spectral components of a corresponding portion of the residual transform signal.
