Claim 12:
13. A method for decoding a data stream having encoded therein an 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 using which the spatially sampled information signal is sub-divided into prediction blocks and a secondary multi-tree subdivision using which tree root blocks which are obtained by subdividing prediction blocks of the primary multi-tree subdivision being greater than a maximum region size into blocks of the maximum region size, are sub-divided into the residual blocks, wherein the method comprises:
receiving and decoding a data stream which comprises the maximum region size; and
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, wherein, if inheritance is indicated to be used, a coding parameter is shared among the residual blocks encompassed by the respective leaf block of the primary subdivision.
