Hello,

I tested point-to-point video connection. It works very well. Video quality is high and CPU utilisation is quite low comparing to other videoconferencing programs.

Please could you explain, how multi-point video communication works.
If there are 10 participants, are then 9 streams sent from the server to every participant?
Are any trans-rating performed or is the speed of video exactly as all participants generate it? E.g if every site transmits 1 Mb/s video, would everybody receive 9 x 1 Mb/s video streams?

What happens if one site has slow (say 512 kb/s) Internet connection and every other user is transmitting 1 Mb/s video stream? Would the slow site receive transcoded video streams? Or wouldn't it receive a video at all?

Greetings and thanks,

Marko

Hello,

Nefsis captures the video image using a variable bit rate encoder and delivers video images based on the captured quality. Nefsis will detect congested or slower downstream connections to any end point and will dynamically throttle the video stream sent to those users.
