A single Slice encoder can only stream to a single destination at a time.
For example, a single stream can be sent to Facebook Live or YouTube Live or Livestream or Ustream or Wowza Streaming Engine or your own RTMP server, or to a single destination with MPEG Transport Stream.
Streaming from a single Slice encoder to multiple destinations simultaneously requires a subscription to the Teradek Core service.
When used with Core, a single Slice encoder can send multiple MPEG-TS and/or RTMP streams simultaneously by way of the Core-controlled Sputnik server.
