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 The configuration of the stream includes the option to delete outdated stream fragments on the server.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.
The path to the destination can be formed in one of the following ways:
- Full path – in this option the path would be constructed as follows: <base url>/<path>/<file>?<aditional params may be also with path and file>
- Path in parameters - in this option the path would be constructed as follows: <base url>?<aditional params may be also with path and file>
- Flat path - in this option the path would be constructed as follows: <base url>/<path>_<file>?<aditional params may be also with path and file>. Any "/" in path should be replaced with "_"
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.

| Billing Codes | Billing codes are used to identify and differentiate traffic on a Zixi Broadcaster for billing purposes. When a billing code is added to a Source or Target, Zixi can track the traffic on that Broadcaster input or output separately from other inputs and outputs on the same Broadcaster. Billing codes are created by Zixi personnel on the Zixi Customer Portal for a particular organization. |
| Billing Code | Enter the billing code that corresponds to this stream. The relevant billing can be obtained from the organization that received the billing code from Zixi. |
| Billing password | Enter the password that corresponds to this billing code. |
