A live stream begins with visual information captured by a camera, converted to digital data (1s and 0s) within the computing device attached to the camera. This data is then segmented, compressed (by removing redundant visual information), and encoded so that it can be efficiently sent out to dozens or millions of viewers. A CDN caches (temporarily saves) each segment of the video so that most viewers get it from the CDN rather than from the origin server, which cuts down on round-trip latency.
Some live streams are private and only viewable by those who have been invited. However, some are public and can be watched by hundreds or even thousands of people. This can expose young people to content that is age inappropriate or potentially harmful, such as violent or sexually explicit material. They may also be at risk of being approached by people who may try to take advantage of them. This could include flattering them with positive comments or gifts, or trying to get them to engage in sexual activity.
It can also be difficult for young people to tell whether a stream is live or not. This can be especially challenging if they are watching an online celebrity or influencer as they may not know the person in question. It is important for them to be aware of the risks and understand that live streaming can be a form of cyberbullying.
