11-5-3. DSK Mask (Option)
The procedure for using DSK as a mask for KEY1 or KEY2 is almost the same as when
setting up a regular key box mask. The DSK signal shape can also be used as a mask for
DSK, but the key and mask would be the same shape. (Mask is shown applied to KEY1 of
M/E2 in example below.)
Setup a key and display the corresponding keyer menu. In the menu select section,
pressing the keyer menu button (DSK, KEY1 or KEY2) while the SHIFT button light ON
allows the user to access the Key Mask line directly.
Select DSK_A or DSK_O for TYPE item in the MASK TYPE line. If you set DSK_A, the
area covered by the DSK mask pattern will consist entirely of background video.
If you set DSK_O, the area covered by the DSK mask pattern will consist entirely of key fill
video (Key Insert signal).
If you set DSK_O, the area covered by the DSK mask pattern
will consist entirely of key fill video (Key Insert signal).
If necessary, set the mask width in the TOP/BOTTOM and LEFT/RIGHT parameter lines.
If you want to hide areas not covered by the mask, set MASK INVERT to OFF. If you want
to hide areas covered by the mask, set MASK INVERT to ON.
