Go to Settings > Live > Channels
To add a new Channel simply press the "Add Channel" button, give the channel a name and select channel type; Push, Pull or Bypass.
This is the most common type of channel, Push channels are used when you want to broadcast from your encoder to Screen9. After creating a push channel, there will be an ingest URL associated with the channel for you to enter in to your encoder.
This type of channel is used when you want to ingest from an external source. You will provide a RTMP URL for Screen9 to ingest from.
This type of channel connects the player directly to a stream. A URL to an HLS stream is required for video playback and optionally an RTMP URL to record the event.
