A Zixi source can be configured to PUSH a single input stream to multiple output targets in parallel. The topology includes a source node receiving a single IP input, while 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.

Source Configuration

The following procedure describes how to configure the Zixi Feeder to push a single stream to two target hosts in a hot redundancy configuration. In order to configure a hot redundancy you will need to create two outputs containing the same Stream ID with the same latency configuration. The procedure does cover instructions on how to configure the Input into the Zixi Feeder.  

To configure the source node (e.g. Zixi Feeder):

1. On the Outputs page of Zixi Feeder, click the New Output button, located in the upper- right end corner of the screen.
2. In the Name field, type a new name for the output. 
3. In the Type field select Push to Broadcaster.  
4. Under Input, in the Input Name field select the relevant name of the input stream . 
5. Under Properties, in the Stream ID field enter a stream ID (alphanumeric) . The same Stream ID will be also configured in the target nodes.
6. Set the desired Max Latency in milliseconds
7. In the Host field, enter the host name or IP of the primary target.
8. Click OK to create the primary output. 
9. On the Outputs page of Zixi Feeder, select the newly created primary output. 
10. In the right hand drop down, select Duplicate.
    A new output is created with identical parameters
11. In the Name field, type a new name for the output. The name should be different than the one used for the primary output. 
    The existing Type, Input Name, Stream ID, and Max Latency fields should remain identical to the primary output configuration.   
12. In the Host field, change the host name or IP to match the secondary target.
13. Click OK to create the secondary output. 

Target Configuration

The following procedures describe how to configure the two target Zixi Broadcasters in a hot redundancy configuration. The two targets use different Stream IDs, as configured in the primary and secondary sources. 

To configure the primary target node (e.g. Zixi Broadcaster):

1. Click the Inputs tab at the top of the primary Zixi Broadcaster administrative screen
2. Click New Input on the upper right hand side of the screen.
3. Select the Push option.
4. Create an input at the primary target, ensuring the “Stream ID” matches that of the primary source output.
5. Configure additional parameters as required. 
6. Click OK.

To configure the secondary target node (e.g. Zixi Broadcaster):

1. Click the Inputs tab at the top of the secondary Zixi Broadcaster administrative screen
2. Click New Input on the upper right hand side of the screen.
3. Select the Push option.
4. Create an input at the secondary target, ensuring the “Stream ID” matches that of the secondary source output.
5. Configure additional parameters as required. 
6. Click OK.

Cost Considerations

This topology duplicates the target side Zixi node software and hardware components. This configuration also requires doubling the up-link bandwidth.  It is recommended to allocate more than twice the expected maximum bit-rate to ensure head room.
