摘要：
A method of encoding video data includes encoding a quantization parameter delta value in a coding unit (CU) of the video data before coding a version of a block of the CU in a bitstream so as to facilitate deblocking filtering. Coding the quantization parameter delta value may comprise coding the quantization parameter delta value based on the value of a no_residual_syntax flag that indicates whether no blocks of the CU have residual transform coefficients.
