Abstract
The invention provides a method of decoding video data in merge mode comprising: constructing a merge candidate list using available spatial merge candidates and temporal merge candidate; deriving motion information using a merge index and the merge candidate list; generating a prediction block using the motion information; generating a residual block by inverse quantizing the quantized block using a quantization parameter and a quantization matrix and by inverse transforming the inverse quantized block; and generating a reconstructed block using the residual block and the prediction block wherein the quantization parameter is generated per quantization unit and a minimum size of the quantization unit is adjusted per picture. Therefore the coding efficiency of motion information by selecting predictor of motion information one among neighboring blocks and a temporal block. Also the coding efficiency of residual block is improved by adaptively adjusting a quantization parameter per quantization unit and generating a quantization parameter predictor using multiple neighboring quantization parameters.
