The terminology that is commonly used around a topic like video conferencing can often be confusing – because it borrows extensively from other networking and technology platforms and yet is unique in several ways.

To decode this vocabulary better, you can refer to Lifesize’s VC glossary, which lists most of commonly used terminology around video conferencing, and you can view it here.

A few extracts from this VC glossary are:

Continuous Presence (CP): “The ability to see multiple participants on a video conference simultaneously.”

Bring Your Own Device (BYOD): “A term to explain when people use their own technology (i.e. laptops, smartphones and/or tablets) for work purposes, instead of a company-owned device.”

Bridge/Bridging: “A device or application allowing multiple locations to connect in a single call. For example, if you want more than two locations to be able to dial in to a single video call, you will need to use a bridge to connect the calls. These can be hardware devices, software applications or integrated endpoint devices. (A bridge is also referred to as an MCU.)”

Gatekeeper: “A device that manages video conference call control. Typically used to manage call bandwidth, dialing strings and other network settings related to video conferencing.”

Redundancy: “The duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe.”
