Figure 1 shows an overview of the system when different variants of the same stream are published using a media encoder, such as Wirecast or FMLE, which can publish multiple profiles of the same stream. The process works as follows:

1. A provision is provided to the stream manager to specify the different variants of the stream that will be published.
2. The stream manager selects a suitable origin and provisions it to expect multiple versions of the same stream.
3. The stream manager returns a JSON object with the details of the origin endpoint that should be used to broadcast.
4. The broadcaster can then use its media encoder to publish to the origin.
