Claim One:
1. A decoder, comprising: an extractor configured to extract, from a data stream, first information related to a plurality of non-overlapping coding sub-blocks within a coding block of an array of information samples representing a video, wherein the plurality of non-overlapping coding sub-blocks are obtained by applying multi-tree spatial subdivision of the coding block, in which each of the plurality of non-overlapping coding sub-blocks has a same resolution as that of the coding block, the first information includes inheritance information with respect to the plurality of non-overlapping coding sub-blocks, the inheritance information is indicative of whether one or more coding parameters of the plurality of non-overlapping coding sub-blocks are to be predicted based on one or more coding parameters associated with the coding block, wherein the one or more coding parameters of the plurality of non-overlapping coding sub-blocks and the one or more coding parameters of the coding block are coding parameters used in an intra coding process; and a reconstruction mechanism configured to: obtain the one or more coding parameters associated with the coding block, if the inheritance information indicates that the one or more coding parameters of the plurality of non-overlapping coding sub-blocks are to be predicted based on the one or more coding parameters associated with the coding block, predict at least one coding parameter to use in the intra coding process for at least one of the plurality of non-overlapping coding sub-blocks based on the one or more coding parameters associated with the coding block, wherein the predicted value of the at least one coding parameter is the same as or differs from that of the one or more coding parameters associated with the coding block; and reconstruct the at least one of the plurality of non-overlapping coding sub-blocks based on the predicted value of the at least one coding parameter.
