Introduction to Home Theater (Home Cinema)
Let's start off by defining our topic. According to the Wikipedia: A home theater is a theater built in a home, designed to mimic (or exceed) commercial theater performance and feeling, more commonly known as a home cinema. Today, home cinema implies a real "cinema experience" at a private home. In other words the goal is to recreate the experience of going to a local theater, in your own home.
There are several key attributes that make going to the local Cineplex a unique experience, which will typically carry over into the design of a home theater.
• Large image size (immersive)
• Sound from all directions (surround sound)
• Low ambient light
• Good acoustics
Initially it may sound like the main purpose of a home theater is to watch movies. For some, watching movies may be their main objective but for many others the home theater will be more versatile, enabling users to not only watch movies but also enjoy sports, TV and games. As we will soon see, defining the purpose of your home theater will be an important step in making it a reality.
The term "home theater" also means different things to different people, depending on your objectives and resources. A flat screen TV, a DVD player and a home-theater-in-a-box (HTIB) plunked down in the family room may be the perfect solution for some. On the other hand your idea of the ideal home theater might be a dedicated room packed with all the latest audio/video goodies that could make a Hollywood producer jealous. And while some people will place more emphasis on video, audiophiles may focus their efforts on the sound reproduction.
Now let's take a look at the main components that make up a home theater system. Most people will immediately identify a large screen TV and surround sound system as the two main ingredients. Throw in a DVD player, cable box and a couple recliners and we're good to go, right? Actually no; the room itself is one of the most important components in a well designed home theater. How the room interacts with the audio and video components will significantly impact the final result.

The room should provide a comfortable environment but should also be able to control sound and light. Both direct and ambient light must be controlled for optimum picture quality and the way sound reflects around the room will greatly affect sound quality. The room dimensions will significantly impact bass sounds and various room treatments may be needed to help control sound reflections (rugs, acoustic ceiling tiles, book cases, sound absorber panels, bass traps, etc). The shape and size of the room, color of the walls, ceiling and floor, furniture, carpet, wall treatments, and lighting all become very important ingredients in a well-designed home theater.
