Home Theater System
A home theater from the definition above consists of 3 major components. We will now go through all the components one after another.


Widescreen TV
The wide screen television is an essential component of a home entertainment center. These TVs display movies in more realistic colours adapted for the human eye. Most wide screen televisions have diagonal screen size of greater than 22-inch.

Wide screen televisions have an aspect ratio of 16:9. This makes them to be more rectangular in shape compared to conventional TVs that have aspect ratio of 4:3. This aspect ratio gives you a more realistic viewing experience of your home theater.

Most wide screen televisions are either High definition (HDTV) or enhanced definition (EDTV). HDTV come with either full HD (1080p) or 720p HD. Note that most home theater sets will not come with a TV so you have to buy your widescreen TV separately or use your existing TV.


The vision of a more realistic audio and video from an entertainment center would have been impossible without the DVD player or Blu-Ray players. DVD players as the name implies playback video in the high capacity multimedia format called the DVD, while Blu-Ray players play a more advanced higher capacity multimedia format.

Most DVD players can also playback CD, however do not assume this feature especially if you intend to playback VCDs and audio CD. Blu-Ray Players can play DVDs and CDs.

In order to take advantage of the theatrical experience that an entertainment center offers, the DVD must have progressive scan or high definition (HD) capability. DVD players are now getting cheaper. With less than 7,000 Naira you can buy a very good DVD player. Good Blu-Ray players cost from 22,000 Naira.

Note that some home theater systems will not come with DVD/Blu-Ray player. In such situation, you will have to buy the DVD/Blu-Ray player separately or use your existing device.


The surround sound system (also called the home theater sound system) is the sound equivalent of the wide screen television. The home theater is all about theatrical video and sound. While the wide screen TV delivers the high quality video, the surround sound delivers high quality audio.

A surround sound system usually (but not always) consists of 6 speakers and some sort of audio system and/or audio amplifier. The speakers are positioned in strategic locations in a room in order to give a realistic experience.

An entertainment center is surely going to improve your movie viewing experience. Watching a movie in your home theater is simply breath taking, with crisp pictures and 3D sound that gives all the thrills of a real cinema.
