You do not need satellite, The xbox one movie apps (Xbox one video, Netflix, LoveFilm e.tc.) are online services and allow streaming from an internet connection either wirelessly or through an ethernet connection.
Do you mean can I play my TV box through the X1? If so yes and no. If it has HDMI out put yes. That will go through the X1. However not with scart etc. I personally disconnected mine as it is pointless. 2 boxes on to watch the same stuff.
