Today, home theater implies as a real “cinema experience” and therefore a higher quality set of components than just an average television with only built-in speakers can provide. A typical home theater includes the following parts:
- Video and Audio Input Devices: One or more video/audio sources. High-resolution movie media formats such as Blu-ray discs are normally preferred, though DVD and/or video game console systems are also used. Some home theaters include an 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.
- Audio Processing Devices: Input devices are processed by either a standalone AV receiver or a preamplifier and Sound Processor for complex surround sound formats such as Dolby Pro-Logic/and or Pro-logic II, X, and Z, Dolby Digital, DTS, Dolby Digital EX, DTS-ES, Dolby Digital Plus, Dolby TrueHD and DTS-HD Master Audio. The user selects the input at this point before it is forwarded to the output.
- Audio Output: Systems consist of at least two speakers, for stereo sound, however, most systems have a 5.1 surround sound system, which has left and right front speakers, a center speaker, left and right rear speakers and a subwoofer. Some users have 7.1 Surround Sound. It is possible to have up to 11 speakers with additional subwoofers.
- Video Output: A large-screen displays either an SDTV, HDTV, or 3D TV. As of 2015, HDTV is the norm. Options include Liquid crystal display television (LCD), plasma TV, OLED.
- Atmosphere: Comfortable seating 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.
