What is live streaming?
From the name itself, you can understand that live streaming means transmitting digital video and audio signals directly from where the shooting is being done. It involves simply sending and receiving an antenna. Thus, you will watch everything in real life, even if the video is being filmed on the other side of the world. Live streaming is mainly done through the internet because it allows the fastest transmission of data, no matter where you are or what kind of device you are using.
For example, if you want to watch a soccer game in Spain from NYC, you can easily manage its live streaming using the internet. Since the internet acts as the fastest channel, there is no lagging of video and audio signals between the transmitter and the receiver. That's why you will be able to watch everything as it is being filmed.
