This has happened several times now and I'm not sure what's causing the following issue...While watching cable broadcast television while my Apple TV is off, all of a sudden my Apple TV will come on and the cable broadcast switches over to my Apple TV with the name of a person I don't know and 4 digit number on the screen. It appears this person is attempting to access my Apple TV. I'm wondering what may be causing this issue. I have a 5th generation Apple TV. How do I get this to stop? Anyone have any ideas? Thanks.
