6. Control Panels
Overview
• Independent keyers. A control panel controls 3 independent linear keyers. A keyer is a video
overlay with discrete key and fill inputs, and separate controls for “clip,” gain, and opacity.
(The keyers and their parameters are functions of the MCPM.)
The panel can select up to 8 keyer “settings.” Some panels allow the operator to redefine the
settings.
• Squeezeback. A 2-D squeezeback generator allows smooth squeeze transitions. A squeeze tran-
sition scales (or crops) the program image over a selected background image. Size, position and
crop attributes can be preset or modified easily. (Squeezeback is a function of the MCPM.)
The panel can select up to 32 squeezeback “settings.” Some panels allow the operator to modify
the settings.
S
The MCPM “mixer/keyers” have no squeezeback generator. When a control panel attaches
a “mixer/keyers,” squeezeback buttons and squeezeback settings are disabled.
S
The MCPM-SDHD and MCE have “enhanced” squeezeback.
• Logo keyers. A control panel controls 2 independent logo keyers. The MCPM stores logos in
memory. Logo layer A is “pre-squeeze” (upstream of the squeezeback generator), while logo
layer B is “post-squeeze” (downstream of the squeezeback generator). There are several types
of logos. (Logos are functions of the MCPM.)
The panel can select up to 64 or 400 logo “settings” depending on the MCPM or MCE under
control. Some panels allow the operator to redefine the settings.
S
The MCPM “mixer/keyers” have only one logo — logo B. When a control panel attaches a
“mixer/keyers,” logo A buttons and logo A settings are disabled.
• Panel Lock. A “panel lock” button locks the Control Panel, preventing inadvertent switching.
Pressing the button again unlocks the panel. The panel continues to reflect the status of the
select MCPM.
• Automation Off. An “automation off” button is a toggle that turns automation off or on.
• Master Fade to Black. A “fade to black” button fades audio to silence and video to matte at a
specified transition rate. Pressing the button again fades up from black/silence. The FTB rate is
an MCPM function.
S
The matte can be configured as any color, not just black.
• GPIO.
A panel can have GPI inputs or outputs buttons as a customer-defined option.
A “GPI-panel” output button triggers one of 2 relay outputs in the panel. Panel-specific outputs
are useful for controlling a resource such as a cart machine. Panel-specific outputs can operate
across all channels.
A “GPI-panel” input button provides the status of one of two panel inputs.
A “GPI-MCPM” output button triggers one of 2 relay outputs in the current MCPM. We say
these are “channel-specific” outputs. (The MCPM must be configured for this.)
A “GPI-MCPM” input button provides the status of one of the current MCPM’s two inputs.
• Audio functions.
Control panels have knobs (or functions) that allow an operator to adjust the preset and program
audio levels and to adjust the main/over audio ratio.
Most control panels also allow an operator to perform “channel swaps” and to change the gain
(and inversion) of any of the internal audio channels.
