Large distributed system
The following system has 72 channels, digital output and a configuration that enables either 20 free movable
video windows or 60 video windows that are movable and scalable within their respective display area. Here
four free movable windows and 48 windows that are limited to their display area are shown.

large distributed system configuration
Three rendering machines are used each consisting out of two O

devices (one for graphic cards and one for
O
MNI

CALER
and input cards) and one rendering processor that connects to the subnet. On the wall there are three
logical display areas, each belongs to one rendering machine.
There are different possibilities to display the video windows. On the one hand a video can be displayed using
multiple input channels one from each rendering machine to form one logical video channel. Such a video win-
dow can be displayed freely movable and scalable on the whole wall regardless of the different display areas. In
our example 20 such video channels could be built.
On the other hand, 60 videos could be displayed, each 20 restricted to one display area but within these bounda-
ries freely movable and scalable.
Also combinations between these both ways to display video are possible. In the example above each rendering
machine provides 16 videos that are restricted to their display area (input card 12, 13, 14 and 15) and together
they are able to display 4 further videos movable over the whole display wall (input card 16). Please refer also
to section
.
To build larger display walls, simply connect further rendering machines to the sub-net. By this virtually unlim-
ited display walls can be set up, all being configured in the way explained in the example above.
