Abstract:
A video encoding method for encoding both the 4:2:0 video and 4:4:4 video formats. The method includes generating blocks of quantized spatial frequency data by quantizing coefficients and generating a matrix of data. The method further includes determining quantization matrices for use with at least two block sizes. The method further includes determining a first quantization matrix for a 32×32 chroma block of samples with respect to a first modification of a first scaling list for quantization of a block of samples smaller than 32×32, and determining, for blocks of another block size different than the 32×32 chroma block of samples, a second quantization matrix by modifying a second scaling list according to a second modification. The second scaling list is different from the first scaling list, and the first scaling list is a reference scaling list for video in 4:2:0 video format.

Claim (Index 6):
The video encoding method as claimed in  claim 2 , wherein the first scaling list is for quantization of a block of chroma samples in respect of video in the 4:4:4 video format.
