Home Theater
Home theaters were originally just a movie projector which played the reels of the movies you made with your movie camera. These movies were viewed on a small screen or on a wall. Today you can view actual movies with the home movie projectors available. Today (as of 2006) there are over 50 models of home theater projector systems available. The prices for these movie projectors are anywhere from $1,000 to $10,000 or more. It is believed that there were about 200,000 home projectors sold in 2006, in the United States alone. Most of those sold for under $2,000. The front projectors (also known as typically projectors), were usually mounted on the ceiling , placed on a shelf or sitting on a table. They would shine their images on the other side of the room.
Most of the home theaters projectors provide wide screen images with a ratio of 16:9. This is the same as the HDTV standards. Most of the business projectors have the 4:3 ratio which is the same as the computers and television sets. The projectors operate in a dark room with none or very little light. Of today’s projectors, a few, very expensive ones still rely on the older CRT technology. Most of them use the LCD, DLP, or LCOS form of technology. Each of these forms of technology has their advantages and disadvantages.
The typical home theater projector is a stand alone piece of equipment which is interfaced with a home theater receiver, or Home Theater PC, speakers, screen, DVD Player, cable box/ satellite box, and other sources. There are several low cost home theater systems which include the built in DVD player and the speakers.
The HTIB, or Home Theater in a box is a common name for an inexpensive home intertainment package. This package usually includes a DVD player, surround sound, and radio tuner, all in one box. They are usually inexpensive and take up very little room, while they give you the advantage of the surround sound of the DVD format. Some of the manufacturers of these systems are Sony, Samsung, Bose, Philips, and Panasonic. These systems are sold as all in one systems for those who do not want to pick them out individually. The HTIB usually has a central receiver unit which contains a DVD player, and also a radio tuner, as well as a series of speakers for the surround sound capabilities. Some of these systems do come without the DVD player. Most of the speakers in these systems are usually small so they can be mounted on the wall or set on a shelf or other tight spots. Some are slim and are made to stand on the floor.
