Data Redundancy
Overview
The HELIOS system supports multiple high availability redundancy modes. This is accomplished by sending video data
from two HELIOS Processors to the same string of tiles at once using bidirectional data ow from each end of the tile
string simultaneously. Illustrated below, are two HELIOS processors and associated switches sending data into strings of
tiles from two directions (top down and bottom up). HELIOS Junior units can also be used to create redundant systems. In
the case of HELIOS Junior, the processors send data directly to tiles without the use of network switches. Since there is
duplicate data on the network, tiles need to know which processor to listen to. This is done by a system of priority. The
processor with the role Main has the highest priority. All of the processors must be connected to an external genlock sync.

NOTE: Tiles must have software version 20.03.0.256 or later to support the HELIOS redundancy features. See the end
of this section for upgrade steps.
