Appendix B: Wall Builder Tutorial
N-Command’s Wall Builder allows you to design walls of any size in minutes using N-Series Networked AV Encoders, Decoders, and
Windowing Processors. The configuration utility is part of the N-Command Controller and provides a user-friendly interface to
customize video wall layouts to suit the need of the installation. The Wall Builder utility allows the manipulation of N-Series encoded
video sources to be arranged in almost any configuration on the video wall. Wall Builder is easy to use and operate, and it allows
you to build a wall on-site or remotely using N-Series Windowing Processors and/or Decoders.
Video walls require a Decoder per display panel, but can be constructed with or without Windowing Processors. See Figure 49
for
an example of a 3x3 wall using nine Decoders.
FIG. 49 Sample Wall Builder Configuration
NOTE: Some advanced configurations require Windowing Processors. Without them, video windows must be bound by the displays.
When using one Windowing Processor per display, video windows can be anywhere on the full video wall pallet at pixel-by-pixel
resolution. Including Windowing Processors in a video wall adds to its presentation capabilities but increases video latency by
approximately 100 milliseconds.
Wall Builder Basics
Keep the following guidelines and terminology in mind while building your wall:
Wall Builder allows you to create multiple layouts for the same wall configuration.
Within a layout there are multiple windows.
The windows can be layered to determine which one is displayed on top (if two windows overlap).
NOTE: Windows can only overlap when using Windowing Processors.
Sample Configuration Using Wall Builder
This tutorial demonstrates a 3x3 video wall configuration using nine N2000 Series Decoders (one for each display).
1. Log in to your N-Command Controller.
2. Select Build > Wall Builder (as shown in Figure 50
).
FIG. 50 Launching Wall Builder
3. The first Wall Builder Setup screen appears. For this tutorial, follow the steps given in FIG. 51 on page 53
to create a wall from
Decoder sources.
*In this example, all Decoders are watching the same stream.
