Transition Controls and Operation
Next Transition Buttons
The Next Transition buttons ( Figure 2-7 ) select whether the next transition will
consist of Background only, Key only, or both. The two buttons are:
■ Next Transition BKGD (Background) — when selected, the next transition
will change only the Background video portions of the on-air signal,
and
■ Next Transition KEY — when selected, the next transition will change only
the Key video portions of the on-air signal.
Both buttons may be selected simultaneously.
Figure 2-7. Next Transition Buttons
If an attempt is made to setup a Key-only transition while Audio Only is
active, there will be a beep audio warning and the setup is ignored.
If an attempt is made to press the BKGD button during preroll, it will be
beeped and ignored.
If an attempt is made to press the KEY button during preroll, it will be
ignored (that is, it will not change its state) but not beeped. This button
press is allowed since key cuts are allowed during preroll.
If one of the buttons tallies high and the other tallies off, the buttons will act
as follows:
■ Pressing and releasing the high tallied button has no effect. It stays high
tally.
■ Pressing and releasing the off tallied button will cause it to tally high.
The other button tallies off.
■ Pressing and releasing both buttons simultaneously results in both tal-
lying high.
If both switches tally high, the buttons will act as follows:
■ Pressing and releasing either will leave that button’s tally high and turn
the non-pressed button’s tally off.
■ Pressing and releasing both buttons simultaneously will have no effect
— both continue to tally high.
If KEY tallies high, and there are no Key Select buttons in the active state (that
is, with high tally) the next transition will have no effect.
