1. A decoder for decoding a coded signaling of a multi-tree structure, the coded signaling comprising an indication of a highest hierarchy level and a sequence of flags associated with nodes of the multi-tree structure unequal to the highest hierarchy level, each flag specifying whether the associated node is an intermediate node or child node, the decoder being configured to:
decode the indication of the highest hierarchy level from a data stream, and then sequentially decode, in a depth-first or breadth-first traversal order, the sequence of flags from the data stream with skipping nodes of the highest hierarchy level and automatically appointing same leaf nodes,
wherein the multi-tree structure prescribes a spatial multi-tree subdivision of a tree root block of a picture of a video which is coded into the data stream, and the decoder is a video decoder.
