OmniStream decoders have the ability to identify missing streams, should an input be disconnected from the
encoder, and will recover the image almost instantaneously. The decoder can access the same stream from two
separate multicast addresses and switch between them, when necessary.
1. Go to the decoder.
2. Click
HDMI OUTPUT
in the menu bar.
3. Under the
Video
section, click the
Backup Mode
drop-down list to select the desired mode.
1. Go to the decoder.
2. Click

3. Under the
Video
section, locate the
Configuration Grace Period
field and enter the desired value, in seconds.
By default, this value is set to
0
(zero).
4. Click the

Configuring Redundant Streams
*
Switching time will be dependent upon the network switch that is used, as well as the number of hops between
encoders and decoders on the network.
Mode
Description
Off
Redundancy off; output will never switch to the backup stream.
Join Active
The decoder sends a join request only when the primary stream is lost or if the decoder
is manually switched to the backup stream. Switch time will not exceed 5 seconds.*
Join Always
The decoder joins both the Primary and Backup stream at the same time. Switch time
will not exceed 0.5 seconds.
During use, the decoder can be switched to another multicast stream. However, if the decoder encounters a missing
stream, during the switch and when redundancy is enabled, then this will cause the decoder to automatically failover
to the multicast source configured as the backup. To prevent the decoder from automatically making the redundancy
switch, when redundancy is enabled, a grace period can be entered. By default, the grace period is set to 0
seconds. If set to 0 seconds, automatic failover will occur if the stream is interrupted, for any reason.
