Patent ID: 10116939

Abstract:
A method of encoding video data in a merge mode can include determining motion information of a current block; generating a prediction block of the current block using the motion information; generating a residual block using the current block and the prediction block; 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 coefficient components of the quantized block using a diagonal scan; entropy-coding the scanned coefficient components of the quantized block; and encoding the motion information, in which when the current block is a second prediction unit partitioned by asymmetric partitioning, the spatial merge candidate corresponding to a first prediction unit partitioned by the asymmetric partitioning is not to be listed on the merge list, the quantization parameter is determined per a quantization unit and is encoded using a quantization parameter predictor, and a minimum size of the quantization unit is adjusted by a picture parameter set.
