A more expensive home cinema set-up might include a Blu-ray disc player, home theater PC (HTPC) computer or digital media receiver streaming devices with a 10-foot user interface, a high-definition video projector and projection screen with over 100 inches diagonal screen size (or a large flatscreen HDTV), and a several-hundred-watt home theater receiver with five to eleven surround-sound speakers plus one or two powerful subwoofer(s).
