Have you ever watched a video on YouTube? It starts playing almost immediately, right? No waiting for the whole video to download first. This is called streaming, and it's the same idea as streaming television.
Streaming television is when you watch TV shows, movies, or other video content on your computer, tablet, phone, or any other internet-connected device like a Smart TV, without the need to download the whole video file first.
When you "stream" a video, it means you're watching it directly from the internet. This is different from how people used to watch TV shows or movies, where they'd have to wait for the show to start broadcasting or rent a DVD from a store.
Streaming services like Netflix, Hulu, and Amazon Prime Video work by storing all the videos on their servers. When you want to watch a particular show or movie, you just search for it on your streaming device, select it, and it starts playing immediately.
This works because your device and the streaming service are able to communicate with each other really quickly, and it's able to send you the video in small pieces as you're watching it, almost like a video game loading levels as you play.
That's basically all there is to it! Streaming television is just a way to watch your favorite shows and movies online, without having to wait by downloading the whole thing.
