The figure below illustrates the Layer Control Section.

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:

• 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.

Following are descriptions of each button’s function.

Background Buttons — press to select an unscaled background on Preview for transition

to or from Program. The button lights when selected. Please note:

• 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.

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.
