Figure 2-8. Layer Control Section
The buttons in the Layer Control Section enable you to select (on Preview) the sources
that will transition to or from Program — including backgrounds, layers, the DSK and the
full screen LOGO.
When you select a blue "layer" button, you are electronically selecting a scaler that you
want to assign as a PIP or key, or modify in some manner. In this way, you control the
overall look on Preview before you transition that look to Program.
Please note the following important points:

Layer
Two background sources, two layers (in the mixer), one DSK and one full screen
LOGO are provided — identical to the layers on an individual ScreenPRO-II.
The buttons are arranged left-to-right in order of visual priority — from the
backgrounds (at the lowest priority) to the LOGO (at the highest visual priority).
Any combination of backgrounds, layers, DSK and LOGO can be selected on
Preview for transition to or from Program.
Note
In both single and widescreen modes, the only restriction is
that BG B and the DSK are mutually exclusive. This occurs
because the BG/DSK Input B is shared between the DSK
and BG B on all individual ScreenPRO-II units.
Important Each ScreenPRO-II unit uses a "lookahead" Preview monitor
that fully represents how the Program output will appear next .
By selecting combinations of PIPs, keys, backgrounds and
the DSK, you are composing a Preview image that will appear
on Program — after the next transition. A "lit" button does not
necessarily mean that the source will transition on or off — it
simply means that it is part of the "look" on Preview.
If the Red LED is lit, the background is on Program.
If BG A is on Program and BG A is selected in Preview, there will be no change of
backgrounds on the next transition.
