The world we live in is characterized by technological development and people nowadays accept technology as part and parcel of their lives. As a general rule human beings seem to cope quite well with technological research but they are not aware of the fact that little by little they tend to govern their lives according to the latest breakthroughs.

However, technology is not meant only to make peoples' lives easier but it also has an entertainment function. We include in the category of entertainment technology home audio equipment. Nevertheless, there are a lot of people who are not acknowledged with the secrets of this type of technology.

First of all, you should know that there is no difference between home cinema and home theatre. They have the same meaning and the same function. Focusing on a definition for the two terms it must said that home theatre was developed as a smaller theatre built in your private home, intended to mimic the "cinema experience". But you should know that home cinema is, actually, the basic field of home audio equipment. This kind of equipment is composed of a wide variety of devices, such as audio electronics intended to home use, like home stereos and surround sound receivers which became the modern mark of home audio equipment. Thus, there is no clear-cut distinction between home cinema and home theatre but they are featured as accessories, and not as standard equipment. Home audio equipment functions as a device of enhancing or replacing your standard equipment. The composition of this type of equipment is quite simple.

The AV receivers are often viewed as the home entertainment system, functioning as the sounds amplificator and serving as the hub of your entire home-theatre system. It is common knowledge that for an excellent "cinema experience" you need a front video projector which takes a video signal and projects the images on a projection screen by means of a lens system. All the modern projectors have the capacity to correct the inappropriate curves or blurriness, using a very bright light in projecting the specific images. The convergence device which combines the feature of a personal computer and a media center software which develops video and music playback is called home theatre PC, HTPC or media PC. Media centre usually has a 10 foot user interface designed to be used in living-room TV and a remote control.

Moreover, there are few types of home theater, such as backyard theater, defined as a version with a  screen which is foldable, a projector and a pair of speakers, but this home theatre relies very much on your backyard space. Then it is home theater in a box, a combination of DVD-Video or Blu-ray Disc player and multi-channel amplifier, including a surround sound decoder, a radio tuner, some speaker wires, certain connection cables, a remote control, a set of five or more surround sound speakers together with a low-frequency subwoofer.

On the whole 21^st century is the century of modernization where home audio equipment is a piece of the puzzle technology represents. If now this kind of equipment is still seen as a fashionable one, soon it will become a common issue. Just take into account the fact that surround sound formats were used in movie theatres dating back to Disney's Fantasia and became available to consumers in the late '80s.
