Claim 19:
20. A non-transitory computer readable medium storing instructions which, when executed by a processing circuitry, cause the processing circuitry to:
subdivide an image into coding tree units (CTUs) including a non-boundary CTU with a size in a horizontal direction and a vertical direction and a boundary CTU having a portion within the image delimited by a horizontal or vertical image boundary based on a bitstream, the portion having a size smaller than the size in a direction perpendicular to the horizontal or vertical image boundary; and
partition the non-boundary CTU and the boundary CTU hierarchically into respective coding units wherein:
the hierarchical partitioning of the non-boundary CTU includes multi-type splitting with a maximum non-boundary multi-type partition depth, multi-type splitting being splitting with the splitting direction being either the vertical direction or the horizontal direction, and
the hierarchical partitioning of the boundary CTU includes multi-type splitting with a maximum boundary multi-type partition depth, wherein the maximum boundary multi-type partition depth is a sum of an adaptive boundary multi-type partition depth and a predefined multi-type partition depth.
