1. A method of coding of video data, the method comprising:
deriving a predicted luma quantization parameter by using a tree type specifying whether a single tree or a dual tree is used to partition a coding tree; and
generating a luma quantization parameter by using the predicted luma quantization parameter, wherein:
the predicted luma quantization parameter is set equal to a luma quantization parameter of a coding unit containing a luma coding block covering a neighboring location when a first condition of a current quantization group is true and a second condition of a neighboring block availability is true, and
the neighboring location is located above the current quantization group.
