A Full guideline towards MCU- Multipoint Control Unit
Video conferencing is a technology that allows 2 or even more people to easily communicate through simultaneous transmissions of video, audio and data over a phone network or an IP network.
What is an MCU?
Three way video conference meetings, four way video conference meetings and more are all called "multipoint video conferences". The equipment and software that make possible a connection between more than two video conferencing clients or systems in the same session are called a Multipoint Control Unit or "MCU".
Functionality of the MCU
A multipoint control unit (MCU) exerts a significant role in video conferencing with functions including:
In the event that participants of a video conferencing are utilizing endpoints with varying video/audio parameters i.e. resolution, frame rate, codec, it is important to translate and consequently normalize the media streams.
Multipoint control unit open source equalizes all audio streams and mixes them. It may even process them in a bid to filter out noise emanating from the environment or to reduce echo.
