ELI5: Explain Like I'm 5

Isochronous signal

Okay kiddo, so you know how sometimes we listen to music or watch videos on our phones or computers? Well, the sounds and pictures we see and hear are made up of tiny signals that are sent from the device to our eyes and ears really quickly!

Now, sometimes we need these signals to be sent at an exact constant rate - kind of like a metronome that keeps a steady beat. This is where isochronous signals come in.

Isochronous signals are signals that are sent at a constant and regular rate, like a clock ticking at the same speed all the time. This is really important in things like video conferencing or live streaming, because we need to make sure the audio and video signals are perfectly synced up with each other.

Think of it like playing a game of catch with a friend. You need to throw the ball to each other at the same speed and at the same time in order to keep the game going smoothly. The same idea applies to isochronous signals - they need to be sent at the same speed and time in order for everything to work properly!
