Producing a Web castProducing a Web cast

Video is sent to an encoder for analog to digital conversion

Encoder is a hardware device, which converts video to a particular type of digital video file

The file is compressed to a manageable sized data stream

File can be accessed by anyone who connects to the streams Web address

To produce a Web cast, the following are needed: a room with a camera, microphone, presenter’s computer, Internet access; and dedicated video and Web servers.
