1. A decoder comprising:

  • an extractor configured to extract a maximum region size and multi-tree subdivision information from a data stream;

    a sub-divider configured to spatially divide an array of information samples representing a spatially sampled information signal into tree root regions of the maximum region size and subdividing, in accordance with a multi-tree subdivision information, at least a subset of the tree root regions into smaller simply connected regions of different sizes by recursively multi-partitioning the subset of tree root regions; and

    a reconstructor configured to reconstruct the array of samples from the data stream using the subdivision into the smaller simply connected regions.
