6.2.1
Cascaded OmniScalers
To increase the amount of video sources that can be displayed on a given number of projection modules and that
can be displayed freely movable, the cascaded O
MNI
S
CALER
configuration can be used. This means that the output
of the O
MNI
S
CALERS
of one O
MNI
B
US
is not connected to the projection modules but to the input connectors of an-
other set of O
MNI
S
CALERS
in another O
MNI
B
US
. The data transmitted from the O
MNI
S
CALERS
of the first O
MNI
B
US
con-
tains already the video information of the respective input cards. In the second O
MNI
B
US
additional video data is
added to the graphics data of the O
MNI
S
CALERS
. O
MNI
S
CALERS
of up to four O
MNI
B
US
devices can be cascaded in this
way.

devices
and a possible result on the display wall. On the right hand side there is shown the current state of the graphical
data as it would be shown on the display wall, if leaving out the following cascaded O
