Description
Quantization sign bit
Quantization multiply control
used to compensate for different weight sum in transposed
polyphase or color space matrix mode, remaining bits are fraction
(largest number is 511/512)
Value range:
gain more precision in the truncated result.
Initial start offset for DTO
Initial zoom delta for 1 pixel in line (signed, LSB = 2
used for non constant scaling ratios
Zoom delta change (signed, LSB = 2
used for non constant scaling ratios
