It's a selection wheel.
which I think is a really good idea.
But we can implement it with simple push buttons , which is much cheaper.
Yeah , like up , down , left and right. Which is good. And then and then  Yeah , so I mean either a channel up and down , volume up and down , next appearing programmes up and down ,  uh and then also  when you get into the different menus on the screen , it's got your things like settings and contrast up and down.
