Section 4 — Menus Overview
Keyer Mask Menu
Touching the
Mask
subcategory button takes you to the Keyer Mask Point
of Use menu ( Figure 220 ). The Mask menu allows selection and control of
the keyer mask(s). Key masking defines areas that are protected from
keying (Inhibit) or always key (Force). The shape of the mask can originate
from a wipe pattern generator or by a selected mask signal (typically a key
fill signal delivered via the Utility bus). Masking can only be done on M/E
keyers.
The M/E (
M/E 1
or
M/E 2
) and keyer delegation (
K1
–
K4
) is made at the top
left of the screen. Once a keyer has been delegated, choose the type of mask
(
Force
or
Inhibit,
or both) from the data pad in the lower right corner. The
example shown here is for a Box Inhibit mask on M/E 1 Key 1.

Mask Sources
For either type of selected mask (Force or Inhibit) five different mask
sources are available and will appear in the data pad on the right of the
screen. Only one mask source can be selected at a time.
