Video Conferencing (Understand The Basics)

The newest thing to hit the technological world is video conferencing.

Videoconferencing uses telecommunications of audio and video to bring people at different sites together for a meeting. This can be as simple as a conversation between two people in private offices (point-to-point) or involve several sites (multi-point) with more than one person in large rooms at different sites. Besides the audio and visual transmission of people, videoconferencing can be used to share documents, computer-displayed information, and whiteboards

There were a lot of problems with the video conferencing technology at first before this procedure became as widely known and used as it is nowadays. The first type of audio video conferencing goes back to the 1960's, when the company AT&T introduced their Picture phone at the World's Fair in New York. This device made it possible fro people to speak to each other and see the person on the other end of the line at the same time, for the first time ever. People were fascinated by this possibility but the device never became popular and was too expensive for most consumers
Video teleconference systems throughout the 1990s rapidly evolved from highly expensive proprietary equipment, software and network requirements to standards based technology that is readily available to the general public at a reasonable cost. Finally, in the 1990s, IP (Internet Protocol) based videoconferencing became possible, and more efficient video compression technologies were developed, permitting desktop, or personal computer (PC)-based videoconferencing. In 1992 CU-SeeMe was developed at Cornell by Tim Dorcey et al., IVS was designed at INRIA, VTC arrived to the masses and free services, web plugins and software, such as NetMeeting, MSN Messenger, Yahoo Messenger, SightSpeed, Skype and others brought cheap, albeit low-quality, VTC

There are various companies online that offer videoconferencing services. The best thing about this is that individuals would be dealing with professionals who can assess the needs and meet thier demands. This would also be ideal for large business meetings, international conferences, etc.

Hiring the services of a professional means that you would not have to do any of the hard work yourself. Trying to figure out how to set up the equipment, and rig the room with slide viewers, lights, microphones, video cameras, is not an easy task. This is why sometimes the services of a professional is required. All you need to do is pay the cost of this service
Videoconferencing devices process and compress video and audio signals so that these signals can be transmitted over different existing telecommunications networks all over the world. The technology is fairly complicated and hard to understand but the video conferencing basics are that video and audio signals get sent to a device called a codec . These signals are processed by the codec and passed on to other people who are in connection with the codec via computers or a video screen.

The definition of video conferencing is that three more sites except for a sender can connect at the same time through a video bridge called a Multi-Point Control Unit (MCU). This bridge ensures that data such as sound and images will be transmitted correctly via the so-called codec, to other people using the video conferencing system. Devices needed to establish a video conference are:
A codec device, A camera, a speaker, a microphone, a monitor to display images, Compression software processing the images and sound sent by the codec, a telecommunication network

Where is video conferencing used?

Those who have friends and family in different parts of the world, may find videoconferencing a welcome addition to their method of communicating with their loved ones.

Video conferencing has proven itself useful not only to businesses but also to the academe.

Through video conferencing, learning institutions can offer online lectures with experts from other countries, who no longer have to travel to deliver their lectures. This has made knowledge sharing very affordable and efficient.

Students who are not able to be present in class may still participate, and learn using videoconferencing. Given that this type of communication can access different locations. Students from around the world now have the opportunity to take classes that are offered elsewhere.
Video conferencing is a new technology that can be useful to everyone, even to people who have relatives or families in other countries. With video conferencing, business and personal communication can be cheaper and more effective.
