Internet broadcasting allows delivery of messages anywhere in the world and can reach an audience more easily than almost any other content-delivery mechanism. The medium also provides targeted delivery of information, instant dissemination of content, and lower individualized broadcast costs. A live broadcast may be made available immediately for viewing upon event conclusion. A broadcast may be for as few as 1 user or as many as 10-15,000 simultaneous users. The faster the connection, the better image quality will be.
Intranets usually offer better image quality, due to faster connection speeds.
As bandwidth improves, the image quality will too. Congestion, or traffic, over the Internet adversely affects image quality. Broadcasts may be protected by passwords. Currently, no encryption exists to allow secure broadcasts. The firewall, which protects networks from intrusion, may interfere with broadcast reception.
