1. Single physical remote for all multimedia devices.
There are so many remotes in your Theater room or living room like Television, Set-top box, Music system, Blu-ray or DVD player, AC, Curtains, and others. It is very difficult to manage all these remotes by your elders or your parents. So you can merge all these remotes in a single remote. You can merge the remote of AC also in this single physical or logical remote.
