What is WI-FI TV?

Wi-Fi tv is something I need! We have so many differnt electronics, games, theatre systems, computers, etc that it would be extremely helpful since I am the one that as to hook all the crap up :). Basically its like a wireless modem from what I understand. You hook it up and it can control all the electronic stuff in your house. You can send signals from like the living room to the kids room or wherever in the world basically. You can watch video from YouTube or other computer sites or programs. I find it very useful and would love to get one. I have actually done some recent research on it to get more information on pricing, who makes them, how/where to get, etc. Hope that helps some!
