摘要：A method can include decoding residual signals to generate quantized
coefficient components; determining an inverse scan pattern and generating a quantizedblock using the inverse scan pattern; deriving a quantization parameter and inverselyquantizing the quantized block using the quantization parameter to generate a
transformed block; and inversely transforming the transformed block to generate aresidual block, in which when the quantization parameter is a chroma quantizationparameter, the chroma quantization parameter is generated using a luma quantizationparameter and an offset parameter indicating a relationship between the luma
quantization parameter and the chroma quantization parameter, the luma quantizationparameter is derived using a differential quantization parameter and a quantizationparameter predictor, and the differential quantization parameter is generated byentropy decoding, and parameters are set according to certain conditions.
