This article provides relevant information regarding the types of streaming media that can be blocked using GFI WebMonitor.
Streaming media is multimedia delivered on demand to the end-user over the Internet. Common forms of streamed media include Internet TV (IPTV), movies, Internet radio, educational media, traffic and surveillance cameras, etc.
A client media player can begin playing the data before the entire file has been transmitted. Delivering live content over the Internet is called 'live streaming,’ e.g., a sports event or newscast. Webcasting is content provided over the Internet for a defined audience. Examples of webcasting events include live events, e.g., lectures and online training session, product launch or demonstration, ceremonies, etc.
