How it works

A Live encoder posts a live stream to Origin, which ingests it, creating a live archive on disk to stream from. Based on incoming requests from viewers, Origin dynamically packages the live stream into the requested format.

To scale this setup for delivery to millions of viewers, a CDN sits in front of Origin, caching Origin's output and handling almost all of the requests.

Viewers can also start a show from the beginning or watch programming from the last couple of days. Origin can generate these recordings from its live archive, the length of which you can configure to suit the needs of your streaming service.

The Interface 1 of the DASH-IF Live Media Ingest specification outlines how the encoder uses HTTP POST to stream the live event to an origin. See LIVE Ingest and Content Preparation for more details.
