On rare occasion, you can experience LOS (loss of signal) — typically due to a poor video,
graphics or computer connection. In these cases, the ScreenPRO-II Controller obeys a
precise set of rules for how to handle the signals:
•
•
•
In each case, when the video signal recovers, the system re-enables it as before.

This section provides information on how the ScreenPRO-II Controller system stores the
characteristics of each input in files, and how those files are used during operations.
During the input setup procedure, after adjusting each input parameter, pressing the
{ SAVE } button saves those characteristics in a file. The file stores all definitions for that
source alone, along with the associated destination.
From that point forward, each time you press that source button and assign it to a PIP or a
Key, the stored file is recalled and the image appears on Preview (typically after a brief
delay). The delay occurs as each input is instantly re-scaled per the file's instructions, and
the scaler is instantly re-programmed with the file's data.
With regards to router connections, an input file is independent of the physical connector.
Even though only certain sources can be connected to specific connectors (e.g., Analog or
SDI), once a connector is selected (on the Input Menu ) and an input file is created for the
source, that file can be recalled on any of the same type of connectors in the system,
provided that a router is properly connected and assigned. This in no way forces all of the
other connectors to only accept that particular kind of source signal.

Scaler LOS — If there is a LOS for a video signal inside a scaler (PIP or KEY),
the video switches to black, but the scaler remains in its current size and position.
Background LOS — If there is a LOS for a background DVI input, the video
switches to the background's selected matte color.
DSK LOS — If there is a LOS for the DSK, the system switches the DSK Off
(specifically, selecting " none " as the type).
From the Miscellaneous Menu , press
Preference Menu .
On the Black Invalid Video line, select the method by which the scaler "loading"
procedure is shown on Preview, when you change inputs:
~
Select ON to show black when scalers are loaded. In addition, Black will
be shown when a background channel ( BG ) becomes invalid, and the
DSK will be turned off when source video becomes invalid.
~
Select OFF to show the full scaler loading procedure, which can
temporarily include non-sync and non-stable video.
