Nowadays technology has developed so far that you can actually recreate the magic of theaters at home, and you have ample systems that can help you do that. Home theater refers to a setup of audio and video equipment in your home that tries to duplicate the movie theater experience. A home entertainment theater system is a home entertainment system intended for the domestic environment and capable of processing in an effective manner; audio, video and graphics information. Large size screens, High Definition Televisions or a projection system with movie screen to project the image on are used as video displays. Stereo systems have also become very prominent by using front speakers with or without some form of woofer or sub woofer, as well as rear and side speakers, and have become prevalent particularly for sound systems used to reproduce sound in home theater video systems for playing back video motion pictures and similar program material.The most important thing that you need to consider before you make the purchase of a home theater system is the actual requirement that you are looking at. Most of us look at simple systems that can recreate the magic but at a lower level, so that your neighbors are not disturbed by the sound that is generated from bigger systems. At its most complex, you can indeed have a custom built home theater that costs tens of thousands of dollars with a high end video projector, latest DVD player and Blu-Ray Disc player, network media player, separate amplifiers for each channel controlled by a master preamp or controller, in wall speakers, and a couple of sub woofers that can just about shake down the entire neighborhood. This is not only going to cost you a lot but also create a bit of disharmony in the neighborhood, as your neighbors are not going to react very nicely of the sound ended up waking them in the middle of the night.As you decide the type of entertainment system that you would like to invest in, you need to first decide the exact room that you intend to place this in. A room which is not used for regular activity would be most suitable for such a system, so that it causes least disturbance to normal activity around the house. In fact lots of people think that such theaters are very expensive and have lots of equipments and cables running all over the place. This is not true. In most homes, though, a home entertainment theater does not consist of an expensive custom installation, or a lot of money. A home theater can be something as simple as a 27-inch TV, a basic DVD player and/or HiFi VCR, an inexpensive stereo or an AV receiver, and simple speakers. Whatever type of system you end up with, as long as it provides the entertainment options you need and like, then it is certainly your “Home Theater”.
