E.3.2 Multipoint Videoconference<br />

Appendix E Introduction to Videoconferencing System<br />

One or multiple MCUs should be set in the multi-point conference. The multi-point<br />

conference networking architecture is rather complicated and can be divided into two<br />

categories according to MCU quantity: single MCU mode and multi-MCU mode.<br />

Single MCU mode<br />

The single MCU mode can be adopted for a few conference terminals distributed in<br />

adjacent area. When the conference terminals call to participate in the conference, they<br />

must get the confirmation from the MCU, and then the MCU will notify the conference<br />

participants.<br />

Multi-MCU mode<br />

There are two kinds of networking structure for multi-MCU mode videoconference system:<br />

star networking structure and layered networking structure.<br />

• Star networking structure<br />

The multi-MCU star networking structure is shown in the figure below.<br />

It is easy to add a new conference terminal in this star structure. The MCU has the<br />

function similar to a switch. Each MCU is equal in this networking structure. The<br />
