This operates well with prerecorded video or in the event you've scheduled Are living video in a very a single-to-many broadcast.
Due to the fact even properly-engineered IP networks tend to possess a little residual packet reduction rate due to reduced-likelihood statistical congestion events and amplification of little bit errors while in the fundamental components, most professional methods use some type of ahead error correction making sure that the encoded video stream may be reconstructed although several packets are lost.
