Also called video teleconferencing. It is a video conference among several users that is provided by video cameras and monitors set up on the customer's premises or in a public conferencing center.
A videoconference is a live connection between people in separate locations for the purpose of communication, usually involving audio and often text as well as video. At its simplest, videoconferencing provides transmission of static images and text between two locations. At its most sophisticated, it provides transmission of full-motion video images and high-quality audio between multiple locations.
A subset of teleconferencing that includes a video element. Videoconferencing has transitioned from relatively crude frame-by-frame video to fluid, real-time transmission. The more realistic videoconferencing systems require T1, DSL, cable, or another high-speed, large-bandwidth medium.
Videoconferencing is a communications medium variously used for lectures, tutorials, workshops, project reviews, remote site visits, etc. A videoconference can be either two way (point-to-point) or multipoint, linking three or more sites with sound and video in real time. Multipoint conferences are technically more demanding. Depending on the system used, a videoconference can also include data sharing such as an electronic whiteboard that all participants can draw on, or text based real time 'chat' (like e-mail but it appears instantly on recipients' screens) and application sharing such as word processors, spread sheets, CAD packages, etc, so that all participants can work on the same file. The most common use for videoconferencing in education is remote lectures delivered from one site to another. This is also the least effective use. The most effective use is an event that engages the interest and participation of everyone involved and which encourages interaction between the different sites.
Communication between two or more groups, or three or more individuals, who are remote from one another, using telecommunications channels for fully interactive video and audio or one-way video and two-way audio; includes full-motion video and limited motion video, and, in some definitions, freeze-frame video images.

Using video cameras and online communications to enable people who are in different places to both see and hear each other in "real time". Videoconferencing is a tool for synchronous learning.
With the aid of webcams, videoconferencing is a method whereby terminals can be linked, using the internet on a secured channel, and meetings can take place with full video and audio capability. Videoconferencing has revolutionised the business world, allowing for meetings to take place between two different continents as if all participants were in the same room.
The face-to-face communication via computers using Web cameras, microphones, speakers, & communication lines to transmit compressed audio & video data. Participants sit in front of a Web camera & speak into a microphone. As this occurs, the data compresses & transmits to another participant who receives the data by viewing the video on a computer screen and hearing audio thru the speakers.
is where two or more individuals interact across several sites with visual and audio contact. In each of the participating sites there may be one or more persons.
The act of conducting a meeting or conference in which at least one party participates via a sound and video link.
A technology allowing people in different locations to communicate via video and audio steams. Videoconferencing can be undertaken through high-speed telephone networks or via the Internet. In addition, new generation telephone services (3G) provide a mobile form of videoconferencing available via mobile telephone.
A system that permits real-time interaction. It involves real-time talk or chat, whiteboard graphics, audio, black and white video, or color video.
A form of audio and visual communication that takes place in real time and makes it possible for immediate consultation between participants who may be separated by vast distances.
The use of computers, video cameras, microphones, and other communications technologies to conduct face-to-face meetings over the Internet.
Interactive communication using video and sound transmitted over telephone lines in real time. A form of multimedia and a common application for ISDN.
Communication across long distances that integrates video, audio and data for contact between sites separated by distance.
Combining video and audio signals to communicate among more than two people.
Video and audio transmitted live via telecommunications that allow people at remote locations to see and hear each other.
Communication between two or more individuals or groups who are remote from one another using telecommunications channels for fully interactive video and audio exchange. This includes full-motion video, compressed video, and, in some definitions, freeze-frame video images.
Conducting a conference between two or more participants at different sites by using to transmit audio and . For example, a point-to-point (two-person) video conferencing works much like a video telephone. Using video and audio signals to link participants at different and remote locations.
Teleconferencing. The use of a two-way video system to communicate with groups at distant locations in part, so that they can simultaneously participate in discussions. videodisc Video storage medium that uses thin circular plates, and translucent plastic, on which video, audio and various control signals are encoded along a spiral track. Optical disc systems use a laser beam to read the surface of the disc.
Communication across long distances with video and audio contact that may also include graphics and data exchange. Digital video transmission systems typically consist of camera, codec (coder-decoder), network access equipment, network, and audio system.()
The use of camera (with microphone) and monitor to allow visual communications over a high-speed communications link (typically 1Mbps or higher) instead of proximity face-to-face communications. Videoconferencing equipment ranges in size from person-to-person, to large group. Users can control camera direction and angle of vision, so that remote users may be shown images other than the user’s face. Person-to-person communications is increasingly being incorporated as another channel in computer communications (see Desktop Conferencing), while use of compression techniques means reasonable quality video over much slower links than traditionally (e.g. 128kbs ISDN).

Video and audio communication between two or more parties
Communication across long distances with video and audio contact that may also include graphics and data exchange. The Video Conferencing Glossary provides more (technical) definitions related to teleconferencing.
There are four main types of interactive videoconferencing. In each type, a location with the appropriate equipment is necessary: Satellite videoconferencing is one-way video usually delivered from an origination site via satellite to multiple remote sites. Telephone, fax and/or keypads supply the means for interaction. Compressed videoconferencing uses a CODEC (compressor/decompressor) to compress the television audio and video signals, from an analog to a digital signal for transmission via ISDN phone lines or the Internet. DS 3 videoconferencing provides full motion, two-way video, voice, and data communications that are transmitted over a fiber optic network. IP videoconferencing allows locations to connect to videoconferences via the Internet using the H.323 standard
