When you watch a live broadcast on the Internet, it usually takes 6 to 20 seconds to view the scenes delivered by the streamer. Even if you send a chat message now to the streamer, you can’t see the streamer’s response unless 6 to 20 seconds have elapsed. Therefore, you should keep watching for 6 to 20 seconds after sending a chat message so that you can communicate with the streamer. The chat message is in text format, sending it immediately, but the streamer responds with a video stream, so it takes 6 to 20 seconds to reach you. This situation is called Latency.
