Initial zoom for 1st pixel in line (unsigned, LSB = 2
Quantization shift control
Used to change quantization before being multiplied with 0.5.
Quantization sign bit
Initial start offset for chroma DTO
(Used for 4:2:0 scaling and de-interlacing only.)
Initial start offset for DTO
Initial zoom delta for 1 pixel in line (signed, LSB = 2
Used for non-constant scaling ratios.
Line offset for chroma line count (signed, needed for slicing only)
Filter lengths differ when in de-interlacing mode.
