This document discusses multipoint video conferencing and its key features. Multipoint conferencing allows three or more locations to connect simultaneously, beyond traditional point-to-point calls. It is driven by business needs for global collaboration and an increasingly mobile workforce. Emerging options for endpoints now include smartphones, tablets, and web browsers. Multipoint control units (MCUs) act as the video bridge to connect multiple locations, and can be integrated into endpoints, standalone hardware, hybrid cloud/on-premise models, or cloud-based and on-demand. As more devices support video, the ability to connect across platforms (multiplatform) is becoming increasingly important.
