Claim One:
1. A decoder for reconstructing an array of information samples encoded in a data stream and representing a spatially sampled video information signal, the decoder comprising: an extractor configured for extracting, from the data stream, subdivision information and inheritance information associated with an inheritance coding block of the array of information samples and having a first hierarchy level of a sequence of hierarchy levels, the inheritance information indicating as to whether inheritance is used, wherein the inheritance coding block is composed of a set of non-overlapping coding sub-blocks, each of which corresponds to a second hierarchy level of the sequence of hierarchy levels, the first hierarchy level being lower than the second hierarchy level, and each of the set of non-overlapping coding sub-blocks having a same resolution as that of the inheritance coding block, extracting, from the data stream if the inheritance is used with respect to the inheritance coding block, an inheritance subset associated with the inheritance coding block, the inheritance subset including at least one syntax element of a predetermined syntax element type, and extracting, from the data stream, respective residual information associated with each of the set of non-overlapping coding sub-blocks; and a predictor configured for copying the inheritance subset including the at least one syntax element into a set of syntax elements representing coding parameters used in an intra coding process corresponding to each of the set of non-overlapping coding sub-blocks, determining, for each of the set of non-overlapping coding sub-blocks, a coding parameter used in the intra coding process associated with the corresponding non-overlapping coding sub-block based on the at least one syntax element, and predicting a respective prediction signal for each of the set of non-overlapping coding sub-blocks based on the coding parameter determined for the coding sub-block, wherein each of the set of non-overlapping coding sub-blocks is reconstructed based on the respective prediction signal and the respective residual information.
