DVB-SH
DVB-SH stands for "Digital Video Broadcasting - Satellite to Handheld". This means that it's a way to send TV signals to tiny devices you can hold in your hand, like your smartphone or tablet. It's like when you watch a TV show on your TV at home, but instead of being sent through cables, it's sent through the airwaves like a radio signal.
Let's imagine you and your friend are playing catch with a ball. You throw the ball to your friend, and they catch it. Then they throw the ball back to you, and you catch it. This is kind of like how DVB-SH works. The TV station sends a signal to your device, and your device catches it. Then your device sends a signal back to the TV station, saying "I got it!" The TV station knows that you got the signal, so it sends the next part of the TV show to you.
But if you're outside playing catch, sometimes the ball can get blocked by a tree or a building. It's the same with DVB-SH - if something is in the way of the signal, you might not be able to get the TV show. This is why DVB-SH uses something called "multi-path propagation" to try and get around obstacles. Imagine you're playing catch with your friend again, but this time there are some trees in the way. Instead of just throwing the ball directly to your friend, you throw it so that it bounces off the trees and then goes to your friend. This way, even if something is in the way of the signal, the signal can still bounce around and get to your device.
So that's basically what DVB-SH is - a way to send TV signals to your phone or tablet, even when you're not at home. It uses signals like playing catch, and can even bounce around obstacles to make sure you can still watch TV on the go.
