Abstract:
A method of decoding video data in merge mode can include constructing a merge candidate list using available spatial and temporal merge candidates; 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 a 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 by using a parameter which specifies the depth between the quantization unit having the minimum size and a largest coding unit, and the quantization parameter is generated using a quantization parameter predictor and a differential quantization parameter.

Claim (Index 1):
A method of decoding video data in merge mode, comprising:\n constructing a merge candidate list using available spatial and temporal merge candidates; 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 a 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 by using a parameter which specifies the depth between the quantization unit having the minimum size and a largest coding unit, the quantization parameter is generated using a quantization parameter predictor and a differential quantization parameter, wherein the quantization parameter predictor is generated using a left quantization parameter and an above quantization parameter when both of the left and above quantization parameters are available, the quantization parameter predictor is generated using the above quantization parameter and a previous quantization parameter when the left quantization parameter is not available, the quantization parameter predictor is generated using the left quantization parameter and the previous quantization parameter when the above quantization parameter is not available, and wherein when both of the left and above quantization are unavailable, the previous quantization parameter is set as the quantization parameter predictor.
