摘要: The quantization of intra-block DC transform coefficients is improved through the use human visual characteristics. method comprises steps converting each plurality blocks included in input digital video signal into a set inter-block or and AC coefficients; selecting an coefficient from said determining quantizer step size based on selected generating quantized size.
