Freeze button
— Press this button to freeze the image in the currently selected
window on the display. The image remains frozen until the
Freeze
button is pressed
again, or a different input is selected.
Input selection buttons
— Press these buttons to select fully configurable inputs 1
through 4. On the DI model, these buttons can also select the four HDMI inputs,
depending on the input configuration of the unit. On the MGP Pro 3G-SDI, input
buttons 1 and 2 select the 3G/HD-SDI inputs and buttons 3 and 4 select the HDMI
sources. When one of these buttons is pressed, its input signal switches to the window
that is currently selected (
).
When an input is selected, pressing its button again mutes the input. The input signal
turns off and the window closes. The button flashes while the input remains muted.
To unmute the input, press its button again. When an input is muted or unmuted, the
window in which it was displayed opens or closes using the currently selected window
transition effect. The Window Configuration menu lets you select a transition effect (for
example, dissolve, curtain, or square wipe) with which the window will open or close
(the default effect is
cut
Virtual video input selection buttons
— Press these buttons to select inputs 5
through 19. These inputs can be configured via remote control to accept standard
definition component video, S-video, or composite video signals only. These inputs
are referred to as “virtual” inputs because they can be configured as a variety of
combinations of component, S-video, and composite video through SIS commands,
the Windows-based control software, or the MGP Pro web pages. They cannot be
configured via the front panel.
The virtual input buttons are arranged in five columns of three buttons each, reflecting
the arrangement of the virtual input connectors on the rear panel.
Like the buttons for the four fully configurable inputs, the virtual input buttons light
when pressed. Repeated pressing of a virtual input button toggles between muting
and unmuting the input. When you press an input button connected to a component
video source, all three buttons in its column light. If you press a button connected to
an S-video source, the top two buttons in the column light. When a composite video
source is selected, only one button lights.
NOTE:
Only one input can be selected in each column.
