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.
