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 9):
The method of  claim 1 , wherein when a size of the transform unit is larger than 4\u00d74, the quantized block is divided into plural subsets, the scan pattern is applied to significant flags, coefficient signs and coefficient levels of each subset, and the plural subsets.
