3.1.8.2.3 Dequantization

  • Article

The quantization factors used for each sub-band are specified in the TS_RFX_TILE (section 2.2.2.3.4.1) structure. A scale value is computed from the quantization factor using the formula shown in the figure in section 3.1.8.1.5. Each coefficient in the appropriate sub-band is dequantized by multiplying it with this scale value and rounded.
