The instant replay is the replaying of video footage of an event or incident very soon after it has occurred.
In television broadcasting of sports events, instant replay is often used during live broadcast, to show a passage of play which was important or remarkable, or which was unclear on first sight. Replays are typically shown during a break.
The replay may be in slow motion, or from multiple camera angles. More advanced technology has allowed for more complex replays, such as freeze frame, frame-by-frame review, and overlaying of virtual graphics. Sports commentators analyze the replay footage when it is being played, rather than describing the concurrent live action.
In Italy the istant replay is often used during and after football matches, and it is often reason of quarrels.
