Claim 6:
7. An encoder for encoding an array of information samples into a data stream, the array of information samples representing a spatially sampled information signal, which is subdivided into residual blocks of different sizes by recursively portioning the array of information samples according to a primary multi-tree subdivision and a secondary multi-tree subdivision, wherein the encoder comprising a processor is configured to:
insert, into the data stream, a maximum region size;
use the primary multi-tree subdivision in order to sub-divide the spatially sampled information signal into prediction blocks;
subdivide prediction blocks of the primary multi-tree subdivision being greater than the maximum region size into blocks of the maximum region size so as to obtain tree root blocks for the secondary multi-tree subdivision; and
use the secondary multi-tree subdivision so as to sub-divide the tree root blocks into the residua blocks; and
insert, into the data stream, for each leaf block of the primary multi-tree subdivision greater than the maximum region size, an inheritance information indicating as to whether inheritance is used or not, and, if inheritance is indicated to be used, share a coding parameter among the residual blocks encompassed by the respective leaf block of the primary subdivision.
