webcasting definition

multimedia, World-Wide Web
(From "World-Wide Web" and "broadcast", sometimes just called "push") Multicasting on the Internet. Webcasting implies real-time streaming transmission of encoded video (or audio) under the control of the server to multiple recipients who all receive the same content at the same time. This is in contrast to normal web browsing which is controlled from the browser by individual users and may take arbitrarily long to deliver a complete document.
Pointcast and Marimba were early pioneers.
