The HTTP Push output stream can be encapsulated in HLS or DASH. The source of the output stream is a predefined adaptive group that has been configured in the Adaptive Groups screen. The configuration of the stream includes the option to delete outdated stream fragments on the server. SCTE-35 markers in the source input will be preserved and used to segment the stream for both HLS and DASH encapsulation. Output streams can be pushed to one Zixi Broadcasters or Zixi Receiver.
Low Latency HLS - Zixi Broadcaster supports low latency HLS delivery using chunked transfer encoding, which starts sending an HTTP response as chunks of data when they are ready before the complete response is available. Chunked transfer encoding can be used with transport stream (TS) segments and with fragmented MP4 (fMP4). For low latency HLS and DASH, Zixi Broadcaster must be used as an origin server. To enable low latency HLS and DASH, select Enable HLS Fast playback on Settings > Live Protocols screen.
To create an HTTP Push Output:
- In the Zixi Broadcaster Outputs page, click
. The New Output window is displayed.
- Select the HTTP Push option (radio button)
- Type in the unique identifier for this output stream in the Output Name.
- Select an Input Adaptive Group to be made available on this output from the adjacent drop-down list. To create an Adaptive Group, see Adaptive Groups.
- Select the Show in Matrix check box to display this stream in the Matrix (see Using the Matrix). Default: not selected.
- Enter the Output Parameters (see Output Stream Parameters Table).
- Click OK. The new Push Output with its settings is created and now appears on the screen.

|---|---|---|---|
| Output Parameters | |||
Stream ID | Specify the unique Stream ID that the remote ZiXi Broadcaster expects. | ||

Target URL | The URL of the destination host for the push stream. Note that 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 | Relevant for Bond Links option. Specify the max bitrate in Kbps for the specific link. | ||
| Backup | 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. | ||
Password | Optional - Specifies 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] | Additional URL Parameters | ||
Delete outdated stream fragments on server | Select this checkbox to delete any outdated stream fragments from the server. | ||
| Use segment name in URL | |||
| 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. |
