    摘要： The present invention concerns an apparatus (10) for encoding a picture (12), configured to partition the picture (12) into leaf blocks using recursive multi-tree partitioning, block-based encode the picture (12) into a data stream (14) using the partitioning of the picture (12) into the leaf blocks, wherein the apparatus (10) is configured to, in partitioning the picture (12) into the leaf blocks, for a predetermined block (801a, 801b, 801c, 801d, 802a, 802b, 802d, 803a, 803b, 803c) that corresponds to a predetermined tree level of the multi- tree partitioning and which extends beyond a boundary of the picture (12), reduce an available set of split modes for splitting the predetermined block (801a, 801b, 801c, 801d, 802a, 802b, 802d, 803a, 803b, 803c) depending on a position at which the boundary of the picture (12) crosses the predetermined block (801a, 801b, 801c, 801d, 802a, 802b, 802d, 803a, 803b, 803c) in order to obtain a reduced set of one or more split modes, wherein, if a cardinality of the reduced set is one, the apparatus (10) is configured to apply the split mode of the reduced set for splitting the predetermined block (801a, 801b, 801c, 801d, 802a, 802b, 802d, 803a, 803b, 803c), and if a cardinality of the reduced set is greater than one, the apparatus (10) is configured to select one of the split modes of the reduced set and to apply the selected one of the split modes for splitting the predetermined block (801a, 801b, 801c, 801d, 802a, 802b, 802d, 803a, 803b, 803c) and to signal the selection in the data stream (14). The present invention further concerns an apparatus (20) for decoding a picture (12), a method for encoding a picture (12) and a method for decoding a picture (12).
