1. A decoder for decoding video data, the decoder comprising one or more processors configured to:
determine whether a coding unit height or a coding unit width of a coding unit is greater than a constant value, wherein in a case that the coding unit height or the coding unit width exceeds the constant value, the coding unit is not allowed to be split by using a binary split;
determine at least one of (i) whether a horizontal position of the coding unit extends beyond a right picture boundary and (ii) whether a vertical position of the coding unit extends beyond a bottom picture boundary;
infer a value of a first flag, specifying whether the coding unit is split, to be equal to a first value indicating that the coding unit is split, in a case that at least one of (i) the horizontal position extends beyond the right picture boundary and (ii) the vertical position extends beyond the bottom picture boundary; and
infer a value of a second flag to be equal to a second value indicating that a quadtree split is performed on the coding unit, in a case that (i) the horizontal position extends beyond the right picture boundary, (ii) the vertical position does not extend beyond the bottom picture boundary, and (iii) the coding unit height is greater than the constant value.
