Home cinema

Basic home theater made up of a home entertainment system consisting of large-screen LCD television and a DVD player, (and a Blu-ray capable PlayStation 3 game console).

Home cinema, also commonly called home theater, are home entertainment set-ups that seek to reproduce the movie theater going experience and mood with the help of video and audio equipment in a private home.

In the 1950s, playing home movies became popular in the United States with Kodak 8 mm film projector equipment becoming affordable. The development of multi-channel audio systems and later LaserDisc in the 1980s created a new paradigm for home cinema. In the early to mid 1990s, a typical home cinema in the United States would have a LaserDisc or VHS player fed to a large rear-projection television. In the late 1990s, home theatre technology progressed with the development of the DVD-Video format, Dolby Digital 5.1-channel audio ("surround sound") speaker systems, and high-definition television.

In the 2000s, the term "home cinema" encompasses a range of systems meant for movie playback at home. The most basic and common system could be a DVD player, a standard large-screen television, and a "home theater in a box" surround sound speaker system with a subwoofer. While a decent common home cinema set-up might more likely include a Blu-ray player or media center appliance/computer with a 10-foot user interface, a video projector and projection screen with a "widescreen" 16:9 aspect-ratio format, and a several thousand-watt home theatre receiver with five to seven surround sound speakers plus a powerful subwoofer.

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

Design

Common set-up of a basic home cinema layout with standard distance for a 10-foot user interface media player with a big-screen TV and 5.1 surround sound speaker configuration. The distance between viewer and TV varies, but is typically around 10-feet with a 32" or larger big-sceen television display.

Today, Home Cinema implies a real "cinema experience" and therefore a higher quality set of components than an average television with only built-in speakers provides. A typical home theater includes the following parts:

1. Video and Audio Input Devices: One or more video/audio sources. High quality movie media format such as example Blu-ray are normally preferred, though they often also include a DVD, VHS player, or video game console systems. Quite a few home theatres today include a HTPC (Home Theater PC) with a media center software application to act as the main library for video and music content using a 10-foot user interface and remote control.
2. Audio Processing Devices: Input devices are processed by either a standalone AV receiver or a Preamplifier and Sound Processor for complex surround sound formats. The user selects the input at this point before it is forwarded to the output.
3. Audio Output: Systems consist of at least 2 speakers, however most common today is 5.1 or 7.1 surround sound system, but it is possible to have up to 11 speakers with additional subwoofers.
4. Video Output: A large-screen HDTV display. Options include Liquid crystal display television (LCD), plasma TV, rear-projection TV, a traditional CRT TV, or a front video projector and projector screen.
5. Atmosphere: Comfortable seating and organization to improve the cinema feel. Higher-end home theaters commonly also have sound insulation to prevent noise from escaping the room, and a specialized wall treatment to balance the sound within the room.

Component systems vs. theater-in-a-box

High-quality home cinemas are assembled from component pieces purchased separately to provide the best combination of equipment for the cost. It is possible to purchase home theater in a box kits that include a set of speakers for surround sound, an amplifier/tuner for adjusting volume and selecting video sources, and sometimes a DVD player. Though these kits often pale in comparison to a custom-built home cinema, they are inexpensive and easy to set up; one needs only to add a television and some movies in order to create a simple home theater. This makes them popular in the public's eyes.

Dedicated home theater rooms

This example is of home theater screening room with video projector mounted in a box on the ceiling. Built-in shelves provide a place for movie decor, DVDs, and equipment. Note the component stack on the right, where the audio receiver, DVD player, secondary monitor, and video game system are located.

Some home cinema enthusiasts go so far as to build a dedicated room in the home for the theater. These more advanced installations often include sophisticated acoustic design elements, including "room-in-a-room" construction that isolates sound and provides the potential for a nearly ideal listening environment. These installations are often designated as "screening rooms" to differentiate from simpler installations.

This idea can go as far as completely recreating an actual cinema, with a projector enclosed in its own projection room, specialized furniture, curtains in front of the projection screen, movie posters, or a popcorn or vending machine with snack food and confectionery. More commonly, real dedicated home theaters pursue this to a lesser degree. Presently the days of the $100,000 and over home theater is being usurped by the rapid advances in digital audio and video technologies, which has spurred a rapid drop in prices making a home cinema set-up more affordable today than ever before. This in turn has brought the true digital home theater experience to the doorsteps of the do-it-yourself people, often for much less than what you would expect to pay for a low budget economy car. Current consumer level A/V equipment can meet and often exceed in performance what you would expect to experience at a modern commercial theater.

Seating

Home theater seating consists of chairs specifically engineered and designed for viewing movies in a personal home theater setting. Most home theater seats have a cup holder built into the chairs' armrests and a shared armrest between each seat. Some seating is movie theater-style chairs like those seen in a movie cinema, which features a flip-up seat cushion. Other seating systems have plush leather reclining lounger types, with flip-out footrests. Additional features like storage compartments, snack trays, Tactile transducers (nicknamed "Bass Shakers"), or even electric motors to recline the chair are available.

Backyard theater

In places that have the proper outdoor atmosphere, it is possible for people to set up a home theater in their backyard. Depending on the space available, it may simply be a temporary version with foldable screen, a projector and couple of speakers, or a permanent fixture with huge screens and dedicated audio set up poolside. Due to the outdoor nature, it is quite popular with BBQ parties and pool parties.

Some specialist outdoor home cinema companies are now marketing packages with inflatable movie screens and purpose built AV systems.

Some people have built upon the idea, and constructed mobile drive-in theaters that can play movies in public open spaces. Usually, these require a powerful projector, a laptop or DVD player, outdoor speakers and/or an FM transmitter to broadcast the audio to other car radios.

History

1950s, 1960s, and 1970s

In the 1950s, home movies became popular in the United States and elsewhere as Kodak 8 mm film (Pathé 9.5 mm in France) and camera and projector equipment became affordable. Projected with a small, portable movie projector onto a portable screen, often without sound, this system became the first practical home theater. They were generally used to show home movies of family travels and celebrations but also doubled as a means of showing private stag films. Dedicated home cinemas were called screening rooms at the time and were outfitted with 16 mm or even 35 mm projectors for showing commercial films. These were found almost exclusively in the homes of the very wealthy, especially those in the movie industry.

Portable home cinemas improved over time with color film, Kodak Super 8 mm film film cartridges, and monaural sound but remained awkward and somewhat expensive. The rise of home video in the late 1970s almost completely killed the consumer market for 8 mm film cameras and projectors, as VCRs connected to ordinary televisions provided a simpler and more flexible substitute.

1980s

The development of multi-channel audio systems and LaserDisc in the 1980s added new dimensions for home cinema. The first known home cinema system was designed, built and installed by Steve J. LaFontaine as a sales tool at Kirshmans furniture store in Metairie, Louisiana in 1974. He built a special sound room which incorporated the earliest quadraphonic audio systems and he modified Sony trinitron televisions for projecting the image. Many systems were sold in the New Orleans area in the ensuing years before the first public demonstration of this integration occurred in 1982 at the Summer Consumer Electronics Show in Chicago, Illinois. Peter Tribeman of NAD (USA) organized and presented a demonstration made possible by the collaborative effort of NAD, Proton, ADS, Lucasfilm and Dolby Labs who contributed their technologies to demonstrate what a home cinema would "look and sound" like.

Over the course of three days, retailers, manufacturers, and members of the consumer electronics press were exposed to the first "home like" experience of combining a high quality video source with multi-channel surround sound. That one demonstration is credited with being the impetus for developing what is now a multi-billion dollar business.

1990s

In the early to mid '90s, a typical Home Cinema would have a LaserDisc or VHS player fed to a large screen: rear projection for the more affordable setups, and LCD or CRT front projection in the more elaborate. In the late 1990s, the development of DVD-Video, Dolby Digital and DTS 5.1-channel audio, and high-quality front video projectors that provide a cinema experience at a price that rivals a big-screen HDTV which sparked a new wave of home cinema interest.

2000s

In the 2000s, developments such as High Definition video, Blu-ray Disc (as well as the now obsolete HD DVD format) and newer high-definition display technologies enabled people to enjoy a cinematic feeling in their own home at an affordable price. More audio channels, like 6.1, 7.1, 9.1, 9.2, 10.1, and 22.2 were also introduced for more cinematic feeling.
