•
Grabber
Assigning individual names to the video-/RGB-channels of the input cards.
•
DFRG
One or multiple
Grabber
s get a name as video channel.
•
Sourcelist
for each analog video- and RGB source a name and the type of the signal must be defined. These sources are
grouped in one or multiple sourcelists.
•
Routes
Here it is determined which
Sourcelist
shall be available for which video/RGB channels.
•
Cables
This section describes the cabling of each analog video or RGB source through the video switcher to the ports
of the input on the cards.
These sections are explained by means of an example. It covers two display walls; one wall is controlled by a

devices whereas the other T

ORM
A consists of a
P

with just one O

. Analog Video- and RGB sources are provided from a video switcher. Streaming
video is provided by the video LAN over IP. P
ROCESSOR
1 functions as server which means it controls the video
switcher via serial connection. P
ROCESSOR
2 is connected to P
ROCESSOR
1 via the LAN. The outputs of the video
switcher are divided into two logical sub-devices; one is for the RGB output, the other for the analog video out-
put. For each of the sub-devices a port on the server is defined.
