When most people think about "watching" a movie they think of the visual image. But what really differentiates a home theater from a big screen television is the audio.

This doesn't mean the picture isn't important, only that image and sound come together in home theater to create a richer experience.

The concept of a better theater experience grew from Star Wars director George Lucas' desire for a better film soundtrack. Using Dolby Laboratories sound technology, Lucasfilm accomplished that goal then turned to making the "ideal" theater environment using a technology called THX® (mentioned later).

Lucas then began the notion of reproducing theater-quality sound in the home. The main obstacle he faced was that movie soundtracks were mixed for the spaciousness of a cinema. Therefore, something had to be able to convert cinema sound to the smaller home theater environment.

Basic Home Theater Components

The very basic elements necessary to create a home theater are a 37" or larger television, a movie playing device, speakers, and a surround sound capable stereo receiver.

A general rule in home theater is that you get what you pay for. It is possible to put together a lower-end home theater system from scratch for under £2000. But there are some upgrades that are worth the extra money. A basic system can be upgraded by going with a larger television, DVD player, six quality speakers, and a Dolby Pro Logic® or Dolby Digital® receiver.
