Derivation of processing area for parallel processing in video coding

Abstract:

A video coder may determine a partitioning of a current picture of the video data into a plurality of partition blocks. The video coder may determine a plurality of processing areas in a unit in the current picture having sizes, where an average size of all of the plurality of processing areas in the unit is greater than or equal to a parameter N, and where determining the plurality of processing areas in the unit includes defining a processing area of the plurality of processing areas that has a size that fits two or more adjacent partition blocks of the plurality of adjacent blocks. The video coder may independently code coding units (CUs) within the processing area having the merged two or more adjacent partition blocks.
