Home audio and video setups are as individual as the people who own them. At its most basic, a home theater includes a TV, some speakers and an audio/video source.
Home audio systems are audio electronics intended for home entertainment use, such as shelf stereos and surround sound receivers. Home audio generally does not include standard equipment such as built-in television speakers, but rather accessory equipment, which may be intended to enhance or replace standard equipment, such as standard TV speakers. Since surround sound receivers, which are primarily intended to enhance the reproduction of a movie, are the most popular home audio device, the primary field of home audio is home cinema.
Home video is pre-recorded media that is either sold, rented or streamed for home entertainment. The term originates from the VHS/Betamax era, when the predominant medium was videotape, but has carried over into current optical disc formats like DVD and Blu-ray Disc and, to a lesser extent, into methods of digital distribution such as Netflix, Hulu, and Amazon Video. The home video business distributes films, telemovies and television series in the form of videos in various formats to the public. These are either bought or rented and then watched privately from the comfort of consumers' homes. Most theatrically released films are now released on digital media, both optical (DVD or Blu-ray) and download-based, replacing the largely obsolete VHS (Video Home System) medium. The VCD format remains popular in Asia, though DVDs are gradually gaining popularity.
