Webcasting is a means
of telecasting media - specifically live shows over the Internet.
The signals transmitted are conveyed stepwise from the source
to the encrypter which in turn directs information to the
server which is then made available to viewers.
The source for webcasts can be any audio-video file in the
form of video tapes, video cameras or telephonic/satellite
signal. The data from the source is conveyed to the encrypter.

the signals from the source into a format capable of being
broadcasted over the Internet. The encrypted signals are directed
to the server.

intranet). The server is provided with software which enables
several users to access the information/audio-video files.
Users can easily view the webcasts if they have an Internet
connection and their computer is supported with suitable software.
