Abstract
An example method of video coding includes receiving a video bitstream comprising a plurality of blocks and a plurality of quantized transform coefficients, and determining a quantized level for a quantized transform coefficient of the plurality of quantized transform coefficients. The method also includes selecting a quantizer from a set of three or more quantizers based on the quantized level, and deriving, using the selected quantizer, a dequantized transform coefficient for a first quantized transform coefficient of the plurality of quantized transform coefficients. The method further includes reconstructing a first block using the dequantized transform value.
