Shifting of Video Conferencing Industry from Hardware based MCU to software Based MCU

Abstract

Multipoint Control Unit (MCU): A multipoint control unit also known as a Video Transcoding Server is responsible for connecting various end points on a single point. Along with end point connection MCU is also responsible for data security, stability, video, and sound quality. MCU controls audio/ video switching tasks, coordinates user devices and software, and interacts with an H.323 gatekeeper (It provides addressing service for H.323 based video conferencing units and optionally can also impose bandwidth restrictions) that manages calls and performs many other important functions. The endpoints can call an MCU on any of the following – H.320 (ISDN), H.323 (IP), SIP (Video Phones), HD (High Definition video).
