Abstract
Some series of ABT split are normatively forbidden in order to limit the number of allowed series of splits, in a way that refines the trade-offs between the amount of allowed split series and the compression efficiency. In particular, a reduced combinatory in terms of allowed split series leads to reduced encoder-side complexity, in the rate distortion search for the best block partitioning. The normative split restrictions provide that when successively using horizontal or vertical then vertical or horizontal asymmetric splits, the considered succession of two splits leads to isolating the sub-area of the input block that is three-fourths the size of the parent block in width and height. Additional embodiments condition allowed splits on transform size, block size, and temporal layer of the slice and slice type.
