Terminology
Primaries
Primaries, or primary colors, are the basic and most pure colors (red, green and blue are
commonly used for display units) that are used to generate all the colors in a display
gamut.
RGB or R’G’B’
The RGB notation is used when the signals are proportional to the tristimulus values X, Y
and Z. The R’G’B’ notation is used whenever we describe the gamma-corrected RGB
components (using a power function such as e.g. ITU.709).
Saturation
#
Similar to the saturation setting on CRT display units. Saturation multiplies C
B
and C
R
with the same factor. The ratio C
B
/ C
R
is constant. The value of the saturation
control is expressed in %.
Safe area
The safe area is the part of the image that is shown on a display for the defined settings
of the area markers.
Scanning Backlight
The LED backlight illuminates portions of the LCD at a time, thereby decreasing the “hold
effect” and masking the LCD response time. Using the scanning backlight option results
in a much better performance of the LCD screen when motion is displayed.
Status bar
The status bar is displayed at the top of the screen and contains all relevant information
related to the selected inputs for window 1 and window 2. Also the display settings are
shown in this status bar.
Toolbox
The Toolbox is a type of OSD menu that appears on the left side of the screen. The
Toolbox is called by a long press (
) on one of the control buttons or one of the fixed
function buttons on the control panel. Not all of those buttons are related to a Toolbox.
The Toolbox allows the user to change advanced settings.
Under Monitor Display (UMD) bar
The UMD bar is a dedicated space at the bottom of the screen that shows TSL protocol
coded information sent through the RS485 Tally serial connector or through the GPI Tally
parallel port. The UMD bar also shows two Tally lights.
Video gain G
The video gain (expressed in dB) is similar to picture and is only accessible to the user at
deeper levels in the OSD menus. The main difference is that Picture drives the power of
the backlights, while Video gain is a multiplication factor applied on the value of the video
signal V
i
in
. Increasing gain results in clipping of the highlights.
Viewport
The viewport setting will cut out the area inside the video that is related to the selected
viewport aspect ratio. This can be used to cut black borders from the input signal.
