Claim 15:
16. A non-transitory computer-readable medium for storing instructions to process data stream associated with a video, comprising:
the 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 data stream is decoded using a method which comprises:
receiving and decoding the 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, inheritance information indicating as to whether inheritance is used or not, wherein, if the inheritance information indicates that inheritance is to be used, a coding parameter is shared among the residual blocks encompassed by the respective leaf block of the primary subdivision.
