1. A decoding method, comprising:
obtaining a current block;
determining a current split mode to be applied to the current block in a set of split modes, each split mode of the set of split modes specifying a single decomposition of a first block into a plurality of second blocks, each second block having a width equal to a width of the first block or corresponding to a predefined sub-division of the width of the first block and a height equal to a height of the first block or corresponding to a predefined sub-division of the height of the first block; and
decoding the current block according to the determined current split mode,
wherein, responsive to the current block extending beyond a single boundary of the picture, determining the current split mode comprises:
decoding information to identify the current split mode in a plurality of split modes for which a split direction is parallel to a direction of the single boundary of the picture,
wherein the information comprises a flag indicating a number of second blocks resulting from a decomposition of the current block according to the current split mode, and
wherein the set of split modes comprises the plurality of split modes.
