1. A method implemented by a decoder, the method comprising:
partitioning a transform tree node (TTN) using a vertical binary tree split when a first TTN dimension is greater than a maximum transform unit (TU) size for the TTN and when the first TTN dimension is greater than a second TTN dimension, wherein the vertical binary tree split is implemented according to the following syntax: verSplitFirst=(tbWidth>MaxTbSizeY && tb Width>tbHeight) ? 1:0;
applying TUs to transform coefficients to generate residual samples; and
generating a reconstructed picture based on the residual samples.
