Videoconferencing Equipment Key Terms

Learn videoconferencing equipment key terms to ensure crisp, clear communications

Use videoconferencing equipment key terms to determine how videoconferencing works. When you figure out the mechanics of videoconferencing, you know how to adjust equipment so it works properly and keeps images and sound clear. The current trends in videoconferencing often go beyond a face-to-face meeting to meetings where hundreds of videoconferences share a single screen or application from remote locations.

As technology advances and businesses use videoconferencing more and more for meetings and trainings, there is a great need for equipment that provides sharp communication. Use and understand videoconferencing equipment key terms to provide these services.

Application sharing

When one user shares an application with another user that does not have the application, they are application sharing. Both users transfer files to each other and use their own mouse and keyboard to work the applications. The main user must give permission for the other person to use the application, or the second user will see the application without being able to use it.

Bridge

The bridge, also called a multi-conferencing unit (MCU), is the connection between three or more sites of conferencing. It works as a data holder, sending out the data among all the conferencing participants.

Compression

To get information through lines with the greatest speed, the information needs reduction. Compression, usually done with a codec, could include the reduction of video or sound quality, or it may get rid of redundancy.

Data

In videoconferencing, data is the information sent between program users. The information runs through cables in digital form.

Echo cancellation

Sometimes the main signal in a transmission puts out unwanted noise that interferes with a conference. Echo cancellation isolates the signals in the transmissions and filters them out.

Full-motion video

This term refers to any images that are not still-frame shots. Although called full-motion, in videoconferencing, images run approximately 10-15 frames per second as 112 kilobytes per second.
