Abstract
A video coder determines a deblocking quantization parameter (QP) value based on at least one of a first QP value and a second QP value. Subsequently, the video coder applies a deblocking filter that is based on the deblocking filter to an edge associated with a first video block. The edge occurs at a boundary between the first video block and a second video block. The first video block is associated with a current coding unit (CU) and the second video block is associated with a neighboring CU. The current CU is included in a first quantization group and the neighboring CU is included in a second quantization group. The first QP value is defined for the first quantization group. The second QP value is defined for the second quantization group.
