Where,
if A bit is set then
AR1 = Window 1’s Red blending factor (ALPHA1_R@VIDOSD1C)
AR2 = Window 2’s Red blending factor (ALPHA1_R@VIDOSD2C)
AR3 = Window 3’s Red blending factor (ALPHA1_R@VIDOSD3C),….
Else if A bit is cleared then
AR1 = Window 1’s Red blending factor (ALPHA0_R@VIDOSD1C)
AR2 = Window 2’s Red blending factor (ALPHA0_R@VIDOSD2C)
AR3 = Window 3’s Red blending factor (ALPHA0_R@VIDOSD3C),….
In case Win01(R), Alpha and Beta value is determined by
Alpha
= AR1/16,
Beta
= (15-AR1)/16
if AR1 == 0xF then
Alpha
=1 and
Beta
=0
if AR1 == 0x0 then
Alpha
=0 and
Beta
=1
