This use case mixes a small number of live streams into a single stream using a single Mixer as diagramed in Figure 1. Possible scenarios include control rooms displaying a mix of camera streams or small conferences where a single live stream is required for view-only participants. For the latter scenario, the conference participants would use a simple HTML page to publish their stream and subscribe to the other participants’ streams, thus not requiring mix-minus audio functionality.
