order of the rendering engines. This means at first the video adapters of the first rendering machine are num-
bered in the scanning order of the PCI slots, followed by the video adapters of the second rendering machine,
etc.
With this standard assignment, a video is restricted to the display area of the rendering engine where the input
card is located. Combining a video adapter of one rendering machine with a video adapter of the same type in a
different rendering engine to a logical video channel allows to display the connected video source in a window
that is freely movable and displayable across both display areas. A logical video channel may contain a video
adapter of every rendering engine, enabling to move this video on the whole display wall.
If considering a distributed system with two rendering machines, each equipped with one Q

, the default configuration would correspond to an entry in the

In the above example, eight different videos can be displayed simultaneously (

). (Note: The number of video channels is not defined in the comment line, but by the number of entries fol-
lowing the rendering machines’ names.) Four videos can be displayed on the left part of the display wall by the
four adapters of the first rendering machine (
engine-1
). The other videos can be displayed on the right part of
the display wall by the four adapters of second rendering machine (
engine-2
).
A configuration of the same system that enables two logic video channels could look like this:

In the above example, two video channels (
channel 3
and
channel 4
) are »logic« video channels. They can
be displayed and moved over the complete display wall. One logic video channel is setup with the adapters 3 of
both rendering machines the other logic video channel is setup with the adapters 4 of both rendering machines.
Channel

and

can be displayed within the left part of the display wall, respectively within the right
part only.
