Abstract
An example method of video coding includes receiving a video bitstream that includes a plurality of blocks and a plurality of quantized transform coefficients. The method includes deriving a dequantized transform coefficient for a first quantized transform coefficient of the plurality of quantized transform coefficients. The method also includes obtaining an adjusted transform value by applying an offset value to the dequantized transform coefficient, the adjusted transform value based on a quantized transform coefficient level and a current state of dequantization. The method further includes reconstructing a first block using the adjusted transform value.
