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.

Claims

exact text as granted — not AI-modified
1 - 16 . (canceled) 
     
     
         17 . A method of decoding video with a decoder, comprising:
 (a) receiving a coding unit (CU) within a coding area of a video frame having CU x and CU y coordinates;   (b) receiving a prediction mode for said coding area of said video frame;   (c) wherein said prediction mode for said coding area of said video frame is coded using the same codeword that is used for a plurality of different prediction modes;   (d) wherein each of said plurality of different prediction modes having said same codeword is differentiated based at least in part on a prediction direction;   (e) decoding said video frame based upon said prediction CU.   
     
     
         18 . The method of decoding video of  claim 17  wherein said prediction direction is based upon any characteristic of said coding unit. 
     
     
         19 . The method of decoding video of  claim 18  wherein said prediction CU is entropy decoded. 
     
     
         20 . The method of decoding video of  claim 18  wherein said prediction mode is based at least in part on a width of said coding unit. 
     
     
         21 . The method of decoding video of  claim 20  wherein said prediction mode is based at least in part on a height of said coding unit. 
     
     
         22 . The method of decoding video of  claim 18  wherein said prediction direction is based at least in part on a height of said coding unit. 
     
     
         23 . The method of decoding video of  claim 22  wherein said prediction direction is based at least in part on a width of said coding unit.
