Abstract

A method of operation of a video system includes: generating a quantization matrix for a video input data, the quantization matrix having a corner seed and a right-bottom sub-quad coefficient estimated based on the corner seed; generating a video bitstream based on the quantization matrix; and generating a reconstructed video data with the video bitstream for displaying on a video device.
