The input cards
For showing information from external sources like video or RGB data on a Barco display wall a set of input cards
is provided. For integration of video the Q
UAD

IDEO

ARD
and the S
TREAMING

is available and for
RGB data the D

can be used. Multiple input cards can be inserted into an E
OS
.
An X video application allows to display the sources connected to the input cards in individual windows on the
display wall, that can be freely scaled and moved within the projection cubes connected to E
OS
. The display op-
tions can be set in a dialog box.
Quad Analog Video Card
Four different video sources (VHS or S-VHS) can be connected to a Q

Dual RGB Input Card
The D

ARD
digitizes one or two analog monitor signals. In dual input mode it supports two monitor
signals with a pixel frequency between 10 MHz and 135 MHz, in single input mode it supports one signal with a
pixel frequency up to 270 MHz. The most common VESA timings are stored as presets. In addition, user defined
timings can be saved. The timing and aspect ratio of the connected RGB signal are detected automatically.
The D

ARD
has an automated static frame rate reduction depending on number and type of the
signals it processes, please see the table below.

To take advantage of the higher frame rate for signals
≤
1280×1024@75Hz in single input mode, the other
socket may be connected to a second signal but that signal may not be displayed on the display wall.
The X video application allows selecting additionally a dynamic frame rate reduction of the source, which must
be multiplied to the static frame rate reduction to obtain the overall frame rate reduction, please refer also to
