Mm.
you don't want separate keys for all of them. You can't. And uh well there can be children friendly where you can programme your remote so that they they are not allowed uh to browse certain channels which you can block them , and you can operate them. So these are the things presently which are seen in the market scenarios at present.
Mm-hmm.
I personally would look at  things like having a u universal remote , is uh um is a good idea , like instead of having  unusual ones for all of them you can think of having , um with multiple functionality possibly with speech recognition.
