a slingbox allows you to watch t.v from your laptop, cell phone, and any other thing that lets you watch t.v you hook up the "slingbox" to your cable at your house and then your able to somehow hook it up to the device you want to watch your home cable on.

I cant figure out if your able to do this from t.v to t.v. I know you can do it from t.v to phone, and t.v to computer but what about t.v to t.v??
