Home Theater System: Audio and Video Requirements

home theatre audio video requirements1

Every fully functioning home theatre system has three basic components– the television or the video display, the sound system, and the source player (provides the picture and the sound). Even now that a cable or a satellite TV is almost always found in every home, still, additional equipment and/or features are installed most of the time to increase the utility of a home theatre set-up.

These are the three major electronic advancements that had been making movie-watching, playing games with an Xbox, or listening to your favourite sounds more gratifying as well as meaningful, and are considered the basic components of a home theatre system.

Now, let me describe these components or elements one by one.

First, consider the visual element. Current innovations that allow video display options are available depending on your personal budget and tastes.

Rear Projection Televisions, which are also known as RPTVs, provide a reasonably-priced screen-sized TV than a television with a larger screen and separate video projector or screen arrangement. As the term applies, with the RPTV the images are projected or reflected into the TV screen from behind it. Not like in a movie theater where a projector is placed in front of a big screen.

At present, there are three types of RPTV technology: CRT, LCD and DLP.

With a CRT or Cathode Ray Tube projection system, there are actually three tubes, each projecting one of the basic colors via a light magnifying lens through a mirror that reflects the image onto the television screen. These colors combine with the help of quality wirings, CRT size and a good lens to provide very high resolution images. By the end of 2012, these big-box screens had finally come to extinction when Mitsubishi, the last company to make and sell RPTVs, announced the end of its TV business.

Another type of rear projection TV is the LCD or the Liquid Crystal Display Television. An LCD TV is both a rear projection and a flat screen. However, LCD rear projection TVs are more compact than the CRT and use less power.

Still another type of RPTV is the DLP or the Digital Light Processing Projection TV, which uses chips to project images onto the TV screen. These are normally designed with a larger rear display and are not flat.

Finally, the Plasma TVs, that are designed to allow different gases to be trapped between two panels of glass, and also an electronic signal that can modify these gases to allow them to display a picture. These televisions are produced with a sleek and thin design and can produce excellent resolution. Plasma TVs create images that display perfectly without any blur.

Whatever, video display you intend to add to your own home theater set up, make sure you measure the location where you are to place the TV that it would fit perfectly there once set up.

Let us now look into the audio elements of a home theatre system.

As you are well aware, the sound system contributes much in the level of enjoyment and functionality of your home theatre set up. What then, would a good audio system require?

Receiver. This feature takes the audio signal, and also, most of the time, the video signal, and channels them to the proper feature of the system.

Amplifier. This feature is what builds up the signal strength before it is routed to the speakers. Most of the time, an amplifier is already built in a receiver, however.

Surround Sound Speakers. Typically, surround sound speakers comes as a set of five for most home theater set ups– a center channel, a right front, right rear, left front and left rear. These speakers, when properly positioned, will make the sound come from the appropriate direction.

Finally, the data or signal source, the third basic element of a home theatre system.

A basic DVD player is a usual signal source in most theater system set ups. The signal coming from the player contains the video data as well as the audio element from the 5.1 surround sound system. Your cable box or digital satellite also works as a signal source for the home theatre.

All these signal sources can be used in one system with the proper wiring and remote programming to give you an excellent viewing or audio experience through your home theatre system.
