Abstract
A video coder that performs block partitioning based on maximum multi-type tree (MTT) depths separately specified for different quadtree (QT) depth levels and for different MTT types is provided. The video coder determines a maximum MTT depth for each of a plurality of possible QT depths. The video coder may also determine a maximum binary tree (BT) depth and a maximum ternary tree (TT) depth. The video coder partitions the current block by QT partitioning into QT partitions at one or more QT depths. The video coder may partition a first QT partition by MTT partitioning into MTT partitions. The MTT partitioning can be limited by the maximum MTT depth specified for the QT depth of the first QT partition, or can be limited by (i) the maximum BT depth when the MTT partitioning uses BT partitioning and (ii) the maximum TT depth when the MTT partitioning uses TT partitioning.
