Abstract:
An image coding method includes generating a prediction block using intra prediction mode or motion information, transforming residual signals generated using an original block and the prediction block to generate a transformed block, quantizing the transformed block using a quantization parameter to generate a quantized block, determining a scan pattern and applying the scan pattern to the quantized block to generate one-dimensional coefficient information, and entropy-coding the one-dimensional coefficient information, wherein a transform type used for transforming the residual signals of luma components is DCT-based integer transform if prediction mode is inter prediction, and a transform type used for transforming the residual signals of chroma components is a DCT-based integer transform.

Claim (Index 1):
An image coding method, comprising:\n generating a prediction block using intra prediction mode or motion information; transforming residual signals generated using an original block and the prediction block to generate a transformed block; quantizing the transformed block using a quantization parameter to generate a quantized block; determining a scan pattern and applying the scan pattern to the quantized block to generate one-dimensional coefficient information; and entropy-coding the one-dimensional coefficient information, wherein a transform type used for transforming the residual signals of luma components is DCT-based integer transform if prediction mode is inter prediction, and a transform type used for transforming the residual signals of chroma components is a DCT-based integer transform, wherein a differential quantization parameter is generated by subtracting a quantization parameter predictor from the quantization parameter, wherein the quantization parameter predictor is generated using a previous quantization parameter of a current coding unit and available quantization parameters of a left quantization parameter and an above quantization parameter of a current coding unit, wherein the quantization parameter predictor is set equal to the previous quantization parameter if both of the left quantization parameter and the above quantization parameter are unavailable, and wherein the quantization parameter is a quantization parameter for the luma components, and a parameter indicating a relationship between the quantization parameter for the luma components and quantization parameter for the chroma components is included in a picture parameter set.
