Imagine you are playing a game of catch with your friend. You throw the ball to your friend and they catch it. But now imagine that you and your friend are very far apart, and the ball takes a long time to travel back and forth between you. This means that there is a delay between when you throw the ball and when your friend catches it.
Broadcast delay is like this game of catch, but with television and video broadcasts. When you watch a TV show or live event on TV or online, there is a delay between when the action happens in real life and when you see it on your screen. This delay is caused by the time it takes for the video and audio signal to travel from the source (like a studio or arena) to your TV or device.
Broadcasters may intentionally add additional delay to a live event for various reasons. For example, they might use a delay to make sure that any potentially offensive language is caught and bleeped out before it reaches viewers. They might also use a delay to allow time for certain technical operations to occur, such as editing or adding graphics.
Overall, broadcast delay is like playing catch over a long distance - it just takes time for the signal to travel from one place to another, and this can create a delay between when things happen and when we see or hear them.
