Abstract
A method of decoding an image can include constructing an amvp candidate list using available motion vector candidates of a left, an above and a temporal motion vector candidate, selecting a motion vector predictor among motion vector candidates of the amvp candidates list using the amvp index, and generating a motion vector using the motion vector predictor and a differential motion vector. The method further includes generating a prediction block using the motion vector and a reference picture index, inversely quantizing a quantized block using a quantization parameter to generate a transformed block and inversely transforming the transformed block to generate a residual block, and generating a reconstructed block. Also, the quantization parameter is generated per quantization unit, a minimum size of the quantization unit is adjusted per picture, and the quantization parameter is generated using a differential quantization parameter and a quantization parameter predictor.
