UDP
Because of the nature of the live streaming we must use UDP to deliver our streams to broadcaster’s receivers. Unfortunately there are a lot of problems that we have using UDP over public networks and Internet. Packets are losing and receiving in wrong order, as result a stream has artefacts and wrong parameters as well. It very often when broadcasters reject streams from cloud based platforms.
M4F
To work this issue out we use the special protocol M4F. It was developed especially for lossless transferring streams over Internet. When you use The Cloud Playout Signalas you must install two servers (master and backup) on the premise. They receive streams from the cloud with M4F then push them to the broadcaster’s receiver via UDP. That’s how it works.
