Vertical chrominance
scaling increment
This value must be set
to the luminance value
YSCY[15:0]
Vertical scaling mode control
Vertical scaling performs linear interpolation between lines
Vertical scaling performs higher order accumulating interpolation, better
alias suppression
No mirroring
Lines are mirrored
