Step 4. Broadcasting a lecture

It is possible to broadcast a recording to remote viewers as soon as you have provided them an IP address of the broadcast and the credentials. To support larger number of viewers, especially when multiple clients are outside of the LAN, you may need to subscribe to Content Delivery Network (CDN). This service redistributes the stream for multiple viewers. Make sure all viewers know the broadcast’s IP address and credentials. They should start a web browser or a media player and use this address to immediately access the broadcast.
