ers. When VIDPRI field is set to zero the OVR1 layer is located above the HEO layer. When
VIDPRI field is set to one, OVR1 is located below the HEO layer.
The blending function requires two pixels (one iterated from the previous blending stage and one
from the current overlay color) and a set of blending configuration parameters. These parame-
ters define the color operation.
