Appendix D. Redundancy
D.1. Overview
The aim of the 1+1 IP redundancy functionality is to protect an IP broadcast event from the failure of an encoder, or
of a source, without any other monitoring equipment.
Note
The 2 encoders must be identical: same hardware, same software, same licenses.
One encoder is the master, the other the slave. Both have the same configuration, same inputs, same encoding para-
meters and same IP destination addresses. The slave asks for the master's channel configuration and re-configures
every time the master's configuration changes.
When an encoder's channel is configured as a slave, users cannot modify this channel. However they can start or stop it.
Both encoders monitor each other and an algorithm allows them to know if they have to stream. It ensures that only
one encoder is streaming at a given moment and that no superfluous streamer change is made.

Monitored conditions:
An encoder chose to mute or unmute following its statuses and its peer's statuses.
• Encoder is up.
• Encoder is running.
• Redundancy is configured.
• Video input is valid.
• Audio inputs are valid.
