Theater Rooms

In the 2000s, the term "home cinema" encompasses a range of systems meant for movie playback at home. The most basic and economical system could be a DVD player, a standard definition (SD) large-screen television with at least a 27 inch (69 cm) diagonal screen size, and a "home theater in a box" surround sound speaker system with a subwoofer. 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-inch (8.3 ft; 2.5 m) diagonal screen size, and a several-thousand-watt home theater receiver with five to seven surround-sound speakers plus a powerful subwoofer. 3D-TV-enabled home theaters make use of 3D TV sets/projectors and Blu-ray 3D players in which the viewers wear 3D-glasses, enabling them to see 3D content.

Home theater designs and layouts are a personal choice, and the minimum set of requirements for a home theater are: a television set or video projector CRT (no new models sold in U.S.), LCDDigital Light Processing(DLP), plasma displayorganic light-emitting diode (OLED), Silicon X-tal Reflective Display (SXRD), Laser TV, rear-projection TV, video projector, Standard-definition television (SDTV), HDTV, or 3D-TV at least 27 inches (69 cm) measured diagonally, an AV receiver or pre-amplifier (surround processor) and amplifier combination capable of at least stereo sound but preferably 5.1 Channel Dolby Digital and DTS audio, and something that plays or broadcasts movies in at least stereo sound such as a VHS HI-FI VCR or LaserDisc player (no new stand-alone models of either are available; VHS VCRs are usually bundled in combo decks with DVD players), a DVD player and/or a Blu-ray disc player, cable or satellite receiver, video game console, etc. Finally a set of speakers, at least two, are needed but more common are anywhere from six to eight with a subwoofer for bass or low-frequency effects.

The most-expensive home-theater set-ups, which can cost over $100,000 (US), have expensive digital projectors and projection screens, and maybe even custom-built screening rooms which include cinema-style chairs and audiophile-grade sound equipment designed to mimic (or sometimes even exceed) commercial theater performance.
