Live event visual amplification

Live event visual amplification is when a large event, like a concert or a sports game, is streamed online so that more people can watch it no matter where they are. This usually involves a lot of cameras that capture the action on the stage or field, and the images are then sent to a computer where they are put together and shown on a big screen or multiple screens. Some events also have large video screens set up so that people in the audience can also see the live streaming video.
