SFU and MCU –– What is The Difference?
Posted by Lisa on November 27, 2020
In addition to the MCU mode, we recently introduced the SFU mode. But what are the MCU and SFU modes and why I am using both? Here is your answer!eyeson’s technology is based on the MCU mode. This means that the streams from all participants get collected in a central entity which then sends back a single stream to each participant. This ensures much greater quality and more stable video/audio quality. In essence, this also explains why eyeson is perfect for large group video meetings.Due to this technology, the bandwidth always stays stable at approximately 2 Mbits. It does not matter how many participants take part in the group video call. The streams are collected in one single stream. This technology is completely unique to us and partly explains why we are able to deliver such top-notch technology.s you might have guessed, the MCU mode is only relevant for meetings with more than two members. Many of our customers have 1:1 video calls. Therefore, our team decided to introduce the SFU mode. This mode accelerates video processing and is especially useful for 1:1 calls.
So how does the SFU mode work?
Your stream is directly sent to your video call participant and vice verse. This happens without additional processing of the video layout. However, this mode is only activated when 2 people have a video call. If a third party joins, we automatically switch your video call to MCU mode. Starting at 3 participants, it makes sense to use the MCU mode again in order to keep the premium video and audio quality. In our tool, we call it fusion. This should help you differentiate between those two modes:
So how is eyeson's 1:1 call different from other providers?
eyeson still processes the 1:1 video calls in the cloud service. As a result, you can use all our eyeson features like screen sharing, file presentation, recording, GIF reactions, snapshots, adjustable video layout, and Quick Join. Moreover, you can broadcast your 1:1 call on Youtube and Facebook. The SFU mode combines the advantages of the server-side processing of the MCU mode and API accessibility while offering a powerful optimized 1:1 video call.During the video call, you can see an icon on the bottom right-hand corner. The fusion mode (MCU) is active when it starts moving. Just have a look and log in to youraccount. Want to see MCU and SFU in action? Make sure to sign up for a free trial today!
