VIDEO ENCODING BY INJECTING LOWER-QUALITY QUANTIZED TRANSFORM MATRIX VALUES INTO A HIGHER-QUALITY QUANTIZED TRANSFORM MATRIX

摘要

Provided is a process including: segmenting a frame of video into a plurality of blocks; transforming each of the blocks to form respective transform matrices; for a given transform matrix, quantizing the given transform matrix with a first quantization matrix to form a first quantized transform matrix; quantizing the given transform matrix a second time with a second quantization matrix to form a second quantized transform matrix; and forming a sequence of hybrid quantized transform matrix values from part of the first quantized transform matrix and part of the second quantized transform matrix.
