Title:
SYSTEMS AND METHODS FOR DERIVING QUANTIZATION PARAMETERS FOR VIDEO BLOCKS IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2019/151257
Kind Code:
A1
Abstract:
This disclosure relates to a method of coding of video data and more particularly to techniques for deriving quantization parameters. The method of coding of video data comprises: determining a predictive quantization parameter for a current video block based at least in part on a quantization parameter associated with a reference video block, a partitioning used to generate the reference video block, and a partitioning used to generate the current video block; and generating a quantization parameter for the current video block based at least in part on the determined predictive quantization parameter.
