The empahsis on video confrencing vidoe comfrencing is on high demand. But video cnfrencing is mainly needed by large industries.
Video conferencing works similar to a telephone, only it also works visually as well. All images and sound carried out by one person is transmitted over the network and sent directly to the other person in the conference. A video conference is mainly used by two people, but multipoint video conferences can be set up to talk to three or more people.
