Reaching your viewers

There are three common ways that live streaming is done:

  1. Point to point streaming: Each viewer connects directly
  2. Enterprise streaming servers: Provide transcoding and user authentication for viewers on a local network
  3. CDN Streaming: Scales to a large number of viewers on the Internet and can be monetized
