Description
Horizontal down scaling coefficient bits [7:0]. Horizontal down
scaling factor = (1 + VSC/128). HDSC is a two's complement
number. If HDSC => 0, then the image is not effected.
Horizontal up scaling coefficient bits [7:0]. Horizontal up
scaling factor = (1 + VSC/128). HDSC is a two's complement
number. If HDSC <= 0, then the image is not effected.
