Output streams can be pushed to one or more Zixi Broadcasters. You can specify multiple destinations (Broadcasters/ZEC (Receivers)) by adding them in the Links section. You can also split a single stream using multiple links and then bond them into a single stream in target Broadcaster using the Bond Links feature. For each of these links, you can specify the max bitrate that can be used. In addition, some links may be specified as backups. The backup links will be used if the bandwidth across all the non-backup links is not enough for the stream (i.e. if a non-backup link is not available, it will not use the backup). Only if the accumulated bandwidth of non-backup links is not enough, then the Broadcaster will stream to a backup link.

To Create a Push Output:

In the ZEC Outputs page, click . The New Output window is displayed.
Type in the unique identifier for this output in the Output Name.
Select an Input Stream to be made available on this output from the adjacent drop-down list.
Select the Show in Matrix check box to display this stream in the Matrix (see ZEC Using the Matrix ). Default: Selected.
Select Push.
Do one of the following:
1. Stream to multiple destinations - you can stream the same identical stream to multiple destinations by entering the destination parameters and then clicking the "+" button to add another destination (see Output Stream Parameters Table).
2. Bonded link to a single destination - you can split the stream into multiple links, which will be forwarded to a single Broadcaster by selecting the Bond Links checkbox (see ZEC Output with Network Bonding).
Enter additional parameters as necessary (see Output Stream Parameters Table).
If you want to encrypt the Output stream, select the Enable encryption checkbox.
Click OK.
The new Push Output with its settings is created and now appears on the screen.

Output Stream Parameters Table

Parameter	Description
Output Parameters
Links
Host	The destination host for the push stream. Note: additional failover destinations can be added by clicking the adjacent “+” button.
Port	Specify the ports to listen on for Push streams. Default: 2088.
IP	Specify the local IP of the NIC that you will be using for this link.
Bond Links	Click this checkbox to split the stream into multiple links, which will be forwarded to a single Broadcaster instance.
Max Bitrate (for Bond Links enabled)	Relevant for Bond Links option. Specify the max bitrate in Kbps for the specific link.
Backup (for Bond Links enabled)	Relevant for Bond Links option. Select this checkbox to define the link as a backup. The backup will be used only if the accumulated bandwidth of the non-backup links is not sufficient.
Stream ID	Specify the unique Stream ID that the remote Broadcaster expects.
Password	Optional - Specify a string to be used at the receiving Broadcaster to authenticate that the pushing ZEC is allowed to push this stream.
Max Latency [ms]	Specify the buffer size that ZEC will keep for error correction. For example, 6000 milliseconds would ensure that the stream is protected for six seconds of errors in the network. Default:6000
Ignore TLS certificate errors	Select this option when streaming to a trusted server that does not have a valid certificate. When this option is selected, ZEC will ignore the TLS certificate errors and transmit the stream to its destination.
Enable Encryption	Select this checkbox to encrypt the Output stream.
Encryption type (for Encryption enabled)	Specify the type of Encryption (AES 128/192/256). Click Generate to generate an encryption key or enter another encryption key.
