IPhone 4 keeps saying 'connected to tv' when playing videos?

Again, with the iPhone. Every time I take a video and try to watch it on the camera roll, it keeps saying 'connected to TV: video playing on the tv' even though I'm not connected to the TV at all! Any help is greatly appreciated as I need to watch some videos I took for a school project please.

It's connected to airplay.press the home screen button twice and swipe till you see the options for brightness e.t.c the will be a button with a rectangle and a triangle press it and select the button that says iphone…
hope i helped
