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
