How exactly does an "IR Input" accomplish this?

Didnt we just talk about this in another post not long ago?

WTF dude. again.... no budgets to work with. No info on what else we need to control. what is going to be connected to these tv's?

EDIT:
less than 2 weeks ago we went through all of this. Is this the same project?
