Abstract
A method of encoding an image in an advanced motion vector prediction (AMVP) mode can include determining motion information of a current block, and generating a prediction block of the current block using the motion information; transforming the residual block to generate a transformed block; quantizing the transformed block using a quantization parameter and a quantization matrix to generate a quantized block; scanning quantized coefficient components of the quantized block; and entropy-coding the scanned coefficient components of the quantized block, in which the motion information is encoded by performing the sub-steps of constructing an AMVP list using available motion vector candidates of a left motion vector candidate, an above motion vector candidate and a temporal motion vector candidate; selecting a motion vector predictor among motion vector candidates of the AMVP candidate list; and generating a differential motion vector by subtracting the motion vector predictor from the motion vector.
