Cloud MCU

Advantages of video calls based on the patented Multipoint Control Unit (MCU)

The streams from all participants will be collected on a virtual cloud server instance. Only 1 single stream (SST) is sent back to all participants.mcu


SFU (Selective Forwarding Unit) 
The stream is directly forwarded to the other participant. This happens without additional processing of the video. sfu
