1. A method for block-based encoding of a picture into a data stream according to a recursive multi-tree partitioning of the picture into leaf blocks, the method comprising:
determining an available set of split modes for a predetermined block, based on a split availability for a specified partitioning depth and at least one of:
a sum of an x-coordinate position of the predetermined block and a width of the predetermined block exceeding the picture's width; or
a sum of a y-coordinate position of the predetermined block and a height of the predetermined block exceeding the picture's height;
selecting from the available set of split modes a binary split mode comprising a vertical binary split mode or a horizontal binary split mode; and
splitting the predetermined block according to the selected binary split mode into two subblocks along a split line that is parallel to a boundary of the picture and centered inside the predetermined block.
