Igloo System Architecture Overview

A standard Igloo system consists of a central media server responsible for managing, receiving, and warping content; projectors which receive video signal from this media server; a tablet for controlling the Igloo software; and potentially client devices that stream content to the media server, using a protocol such as NDI.

The media server and projectors will communicate over a network in order to centrally manage projector settings, and to provide some monitoring and troubleshooting information.

A control tablet typically sits on a wireless network that is able to talk with the media server, in order to send OSC messages to the Igloo Control software.

Clients wishing to send NDI streams to the media server usually sit on the same network as the control tablet, or will be on another network that is able to route through to it. Multicast traffic must be allowed in order for this functionality to work, as NDI works by having clients broadcast their presence to receiving servers.

In terms of cabling, this will be determined by our team on a system-by-system basis. As a rough guide, where high network usage is expected (e.g. content streaming), we typically use and recommend Cat6 Ethernet cabling using 10GbE. In most cases, Cat5e using 1GbE is enough.

A specific, more detailed, overview of these connections and signal flows will be provided in the form of a system diagram showing each component and the connection types between them.

Multi-User Installation of Igloo Software

Igloo software can be installed for all users, rather than the default of per-user installations, during the install process. This installs configuration files underneath C:\ProgramData\Igloo Vision\ which should be accessible to all users on the system. All users will therefore require read access to this folder for the software to work correctly, and write access where they need to make configuration changes, e.g. changing clip banks in Igloo Control.

An alternative to giving all users write access to this folder (potentially a security risk) is to have a set few power users who have these permissions in order to make changes to configuration.

Igloo Software Data Locations

The following locations are used by a default installation of the Igloo software suite. These locations can be modified by customising the install process as required.
