Abstract
A method of partitioning a video coding block for JVET, comprising representing a JVET coding tree unit as a root node in a quadtree plus binary tree (QTBT) structure that can have a quadtree branching from the root node and binary trees branching from each of the quadtree's leaf nodes using asymmetric binary partitioning to split a coding unit represented by a quadtree leaf node into two child nodes of unequal size, representing the two child nodes as leaf nodes in a binary tree branching from the quadtree leaf node and coding the child nodes represented by leaf nodes of the binary tree with JVET, wherein coding efficiency is improved by taking advantage of the similarity of coding modes 2 and 66.
