So we have to keep in mind to to focus not a lot  not that much on the younger pep younger people , but also somewhat on the elderly people. And on my personal preferences , I don't have any mo more time to come with that ,
but like I said , L_C_D_ screen is easily to use
because you have  you can implement a lot of buttons in one remote with not that much buttons. And it should be easy to use. Especially the volume buttons , the channel buttes buttons and the number buttons to zap through the channels. And that is it.
Okay ,
