Streaming Bandwidth Considerations

Streaming and bandwidth usage:

You’ll often hear the term ‘bitrate’ in connection with streaming video. This refers to data pushed through per second (measured in Kilobits per second, or Kbps.) For reliable performance, try to ensure the potential upload bandwidth from your system to the net is around twice the bitrate you choose. You can broadcast at a rate closer to your actual ceiling, but reliable performance cherishes headroom. Even if you can supply good output bandwidth, flow may be constricted elsewhere, such as by the download connection of your audience. A safety margin of around 1.5x the stream bitrate is desirable. This may mean you need to consider using a lower resolution, or lower framerate for your stream – but doing so when required will generally deliver a smoother result (nothing turns viewers off quicker than a stuttering stream).
