In order to protect against device, link connectivity, or software failures, Zixi supports a variety of high-availability topologies by deploying redundant components. Zixi products feature failover mechanisms that utilize alternative components in the event of failure as well as augment redundant external encoder or decoder configurationsA Zixi source can be configured to PUSH a single input stream to multiple output targets in parallel. The topology shows a source node receiving a single IP input simultaneously pushing the stream to two live targets. Two differently named outputs are created at the source using the same Input Stream.  If the latency of the outputs is identical, the streams will be frame synced, provided that the video is synced during its entry.

Hot Redundancy

Hot redundancy, represented in the diagrams by a solid non-dashed arrow, involves two parallel active streams. This enables seamless failover transition between the two streams. It requires two live feeds, doubling the overall bandwidth.

Warm Redundancy

Warm redundancy, represented in the diagrams  by a dashed arrow, involves an primary active stream and a secondary backup stream that is ready to become active in the event of primary failure.

Cold Redundancy

In a cold redundancy configuration, a secondary path is available in a dormant state, requiring a manual switch over to activate in the event of a primary failure

External Video Source Redundancy

Zixi can be configured to co-exist with redundant deployments of 3^rd party peripheral devices such as encoders or IRDs.

Source Encoder / Video Redundancy 

In the event of a loss of source signal, the recovery period of a Zixi Receiver or Zixi Broadcaster can stream from a secondary stream source or local file system. Typically used to stream a technical fault slate or message that the transmission will be resumed shortly.
