Summary

Nearly one out of every four Netflix online video is viewed on a mobile phone. But even in this case, broadcasting comes in high definition. Delivering 4K images despite low telephone bit rate throughput (100KB/s) is the feat that Netflix was able to achieve thanks to researchers at the LS2N (Laboratoire des Sciences du Numérique/digital sciences laboratory) in Nantes. After interviewing numerous users of the American platform, the scientists developed an algorithm that allowed them to broadcast programmes in impeccable quality.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
