2.2.4.2.1.5.2 RFX_COMPONENT_CODEC_QUANT
The RFX_COMPONENT_CODEC_QUANT structure stores information regarding the scalar quantization values for the ten sub-bands in the three-level discrete wavelet transform (DWT) decomposition.
When embedded within the quantVals field of the RFX_PROGRESSIVE_REGION (section 2.2.4.2.1.5) structure, the RFX_COMPONENT_CODEC_QUANT structure contains the scalar quantization values. Each field in this structure MUST have a value in the range of 0 to 15 (inclusive).
When embedded within the yQuantValues, cbQuantValues, and crQuantValues fields of the RFX_PROGRESSIVE_CODEC_QUANT (section 2.2.4.2.1.5.1) structure, the RFX_COMPONENT_CODEC_QUANT structure contains values to be added to the quantization values specified in the quantVals field of the RFX_PROGRESSIVE_REGION structure. Each field in this structure MUST have a value in the range of 0 to 8 (inclusive).
Note that the RFX_COMPONENT_CODEC_QUANT structure differs from the TS_RFX_CODEC_QUANT ([MS-RDPRFX] section 2.2.2.1.5) structure with respect to the order of the bands.
