4.6.2 The video channels
For digitalization of the analog or streaming video data and of RGB sources, a hardware module ( adapter ) is
necessary. Each video and RGB adapter offers one input ( port ). Accordingly, the Q

as well as
the S

has 4 adapters with one port each and the D

NPUT

ARD
has two adapters with
one port each.
The A
RGUS
system automatically creates video channels according to the available input adapters by simply as-
signing one channel per adapter in the order in which the input cards are inserted into the PCI slots of the A
RGUS
O

US
.
In a distributed system in addition the order of the rendering machines is considered when
creating the numbers of the video channels.
In a monolithic system where input cards are located in multiple O
MNI
B
US
devices, the video display is restricted
to the display area of the respective O
MNI
B
US
where the input card is plugged in.
In a distributed system video adapters of multiple rendering machines (one from each rendering machine) can
be integrated to a »logic« video channel. A logic video channel can be displayed on the display area of all ap-
pendant rendering machines.

The configration of logical video channels is done by means of the configuration script
EOSconfig, please refer to section
3.4.3 Configuring a distributed system . Additional background
information about the configuration of logical video channels can be found in section 6.1.6
