Description
In "8.8.3.6.3 Decision process for chroma block edges",
The variable QpP is derived as follows:
– The luma location ( xTbP, xTbP ) is set as the top-left luma sample position of the transform block containing the sample p0,0, relative to the top-left luma sample of the picture.
– If TuCResMode[ xTbP ][ yTbP ] is equal to 2, QpP is set equal to Qp′CbCr of the transform block containing the sample p0,0.
...
The variable QpQ is derived as follows:
– The luma location ( xTbQ, xTbQ ) is set as the top-left luma sample position of the transform block containing the sample q0,0, relative to the top-left luma sample of the picture.
– If TuCResMode[ xTbQ ][ yTbQ ] is equal to 2, QpQ is set equal to Qp′CbCr of the transform block containing the sample q0,0.
