Output streams can be pushed to one or more Zixi Broadcasters and Zixi Receivers. You can specify multiple destinations (Broadcasters/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 Zixi 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 are 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 Zixi Broadcaster 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:
- 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).
- Bonded link to a single destination - you can split the stream into multiple links, which will be forwarded to a single Zixi Broadcaster by selecting the Bond Links checkbox (see ZEC Broadcaster Output with Network Bonding).
- Enter additional parameters as necessary (see Output Stream Parameters Table).
- 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. |
| IP | Specify the local IP address. |
Max Bitrate (for Bond Links enabled) | Relevant for Bond Links option. Specify the max bitrate in Kbps for the specific link. |
Bond Links | Click this checkbox to split the stream into multiple links, which will be forwarded to a single Zixi Broadcaster. |
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 bandwith of the non-backup links is not sufficient. |
Stream ID | Specify the unique Stream ID that the remote Zixi Broadcaster expects. |
Password | Optional - Specify a string to be used at the receiving Zixi Broadcaster to authenticate that the pushing Broadcaster is allowed to push this stream. |
Max Latency [ms] | Specify the buffer size that Zixi Broadcaster 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, Zixi Broadcaster 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. |
| Enable IFB/Talkback | Select this checkbox to enable IFB/Talkback for one-way communication from the director or assistant director to on-air talent or a remote location. Selecting the checkbox allows the decoder with a Zixi Receiver to send audio back to the encoder with a Zixi Feeder. This offers the ability to, for example, give audio feedback to the camera operator. |
| Port | The port that will be used to send the audio feedback. |
