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 termed ‘Live streaming’, for example a sports event or news cast. Webcasting is content delivered over the Internet for a defined audience. Examples of webcasting events include live events (delivered as they are happening) such as lectures and online training session, a product launch or demonstration, ceremonies etc.
