Okay kiddo, have you ever played a game of catch with a friend? Sometimes, when you throw the ball to your friend, it takes some time for them to catch it. This is kind of like delay encoding in video and audio.
When you watch a video or listen to music on your computer, it takes some time for the computer to process all the information and play it for you. Delay encoding is when the computer stores the video or audio data for a short amount of time, so that it can process it and play it smoothly for you.
It's like your friend catching the ball, but instead of throwing it right away, they take a second to prepare themselves and then catch it. This makes sure that they catch the ball cleanly, and you can keep playing the game without any interruptions.
Delay encoding helps to make sure that video and audio play smoothly on your computer, so you can enjoy your favorite shows and songs without any annoying interruptions.
