Decoder for reconstructing an array of information samples representing a spatially sampled information signal, which is subdivided into a multi-tree structure of leaf regions of different sizes by multi-tree subdivision, from a data stream, wherein the multi-tree structure is divided into a primary and a sub-ordinate sub-division defined in a sub-ordinate manner to each other, so that a tree-root block of the primary sub-division is sub-divided into leaf blocks of the primary sub-division which, in turn, form the tree-root blocks of the sub-ordinate sub-division, further sub-divided into leaf regions of the multi-tree structure, each leaf region of the multi-tree structure has associated therewith a hierarchy level out of a sequence of hierarchy levels of the multi-tree subdivision, each leaf region of the multi-tree structure has associated therewith coding parameters, the coding parameters are, for each leaf region, represented by a respective set of syntax elements, each syntax element is of a respective syntax element type out of a set of syntax element types, and the decoder comprises an extractor for extracting the multitree structure from the data stream, so as to obtain an inheritance information from the data stream, the inheritance information indicating as to whether inheritance is used or not, and if inheritance is indicated to be used, at least one inheritance region of the array of information samples which is composed of a set of the leaf regions of the multi-tree structure, corresponds to a hierarchy level of sequence of hierarchy levels of the multi-tree subdivision, being lower than each of the hierarchy levels with which the set of leaf regions of the multi-tree structure are associated, and is formed by a leaf region of the primary sub-division; wherein the extractor is further configured to extract an inheritance subset including at least one syntax element of a predetermined syntax element type from the data stream per inheritance region, wherein the at least one syntax element of the predetermined syntax element type is an intra-prediction mode syntax element, wherein the decoder is configured to decode, in a residual decoding order, a residual signal for each of the leaf regions of the multi-tree structure which the respective inheritance region is composed of, copy the inheritance subset into a corresponding inheritance subset of syntax elements within the set of syntax elements representing the coding parameters associated with the set of leaf regions of the multi-tree structure which the respective at least one inheritance region is composed of, and calculate, in the residual decoding order, a separate intra-prediction signal for each of the leaf regions of the multi-tree structure which the respective inheritance region is composed of, according to an intra-prediction mode indicated by the intra-prediction mode syntax element, by using neighboring samples of a reconstructed signal of already reconstructed leaf regions of the multi-tree structure as a reference signal, with reconstructing the respective leaf region of the multi-tree structure by adding the intra prediction signal and the residual signal. decode, in a residual decoding order, a residual signal for each of the leaf regions of the multi-tree structure which the respective inheritance region is composed of, copy the inheritance subset into a corresponding inheritance subset of syntax elements within the set of syntax elements representing the coding parameters associated with the set of leaf regions of the multi-tree structure which the respective at least one inheritance region is composed of, and calculate, in the residual decoding order, a separate intra-prediction signal for each of the leaf regions of the multi-tree structure which the respective inheritance region is composed of, according to an intra-prediction mode indicated by the intra-prediction mode syntax element, by using neighboring samples of a reconstructed signal of already reconstructed leaf regions of the multi-tree structure as a reference signal, with reconstructing the respective leaf region of the multi-tree structure by adding the intra prediction signal and the residual signal.
