Different video conferencing scenarios

Simple scenarios

MCU with three or more endpoints

Figure 4: MCU with three or more endpoints

This is the simplest video conferencing scenario. Two endpoints could make a point-to-point call but when

three or more endpoints want to hold a video conference, they need an MCU to co-ordinate the conference

and to send the video and streams from all the endpoints to each endpoint.

In this scenario three endpoints are contributing to the conference and the PCs are streaming. This means

they see and hear the three participants but they cannot contribute themselves.
