What is the brand and model I.D. of the TV?
It might not be a matter of even being able to install any apps/software onto the TV itself but rather you'll need to buy the appropriate set-top box or device so the TV can be connected to your home network. Then you can use a mobile device (smartphone or tablet) as a remote controller, installing the apps you need to your mobile device. Which, just to clarify things, also leads to the question of do you have WiFi setup at home?
