BLOCK PARTITIONING FOR IMAGE AND VIDEO CODING

Abstract:

A video encoder and video decoder are configured to determine a partitioning for a picture of video data based on a virtual pipeline data unit (VPDU) size. For example, the video encoder and video decoder may determine a maximum ternary tree size to be in the range of a minimum allowed block size to a minimum of the VPDU size and a maximum coding tree unit (CTU) size, and/or determine a minimum quadtree size to be in the range of a minimum allowed block size to a minimum of the VPDU size and the maximum CTU size.
