ELI5: Explain Like I'm 5

CI+

CI+ (Common Interface Plus) is like a magic box that helps your TV watch special channels that need an extra layer of security. Think of it like a secret password that you need to use to watch certain shows.

This box goes into a special slot in the back of your TV called the common interface slot. Once it's in there, you can watch channels like Pay-Per-View or other special channels that need a little extra protection.

But here's the trick: to use the magic box, you also need something called a smartcard. The smartcard is like a VIP pass that lets you into those special channels. You put the smartcard into the magic box, and the box says "aha, you're allowed in" and then shows you the cool channels.

So, in short, the CI+ is a special box that helps your TV watch special channels that need extra security, and you need a smartcard to use it.
