Buyers Guide to Home Theater Projectors

Buyers Guide to Home Theater Projectors
By Warren Thompson

Over the years, I have grown really attached to my home theater system. I must say, of all the rooms in the house, my own little movie theater is the one I could not live without. I am absolutely in love with my home theater system and, if you are anything like me, I am sure you will love yours too. I found, when I was initially building my system, that there was so much information to absorb. Every product out there seemed better than the next, and I found myself unsure about which to buy. Here are a few things to keep in mind when shopping for a new home theater projector.

There are two main types of projectors on the market; DLP and LCD. DLP stands for digital light processing. It was invented by Texas Instruments, and utilizes a microscopic array of over 2 million mirrors. DLP has a higher contrast than LCD, but there are some unfavorable consumer reports that note something called the ainbow effect. The ainbow effect is noticeable when looking from one side of the screen to the other, and is characterized by a sudden burst of color.

LCD stands for liquid crystal display. These projectors have three distinct glass LCD panels inside; one for each component of the video signal (red, green, and blue). While DLP chips reflect light, the LCD panels allow light to pass through them. LCD projectors produce brighter images, and they are known for having excellent color saturation. In the end, you will be hard-pressed to notice a great difference between the two types of projection systems.

When shopping for a new projector, keep your particular needs in the forefront of your thoughts. As I mentioned above, it is really easy to lose yourself in the minutiae of each particular system. Connectivity is a definitely something to be mindful of. Make sure that you are able to connect all of your components, including your gaming system. Nothing beats playing Halo in real-life size! Contract ratio is another important factor; the higher the ratio, the better the picture will be.

The brightness of your projector is another thing to consider. Light output is measured in ANSI (American National Standards Institute) lumens. You will want to avoid a projector that produces anything shy of 1000 lumens. As you are likely aware, the projection resolution is extremely important. This refers to the number of pixels that can be displayed on the screen. Go for something that is no less than 1024x768, as this will allow you to fully appreciate the depth and quality of HDTV. In the end, you should buy the projector that is in line with your needs and your budget. Soprano's is coming on right now! Time to go!

Film Projector Rentals

Film Projector Rentals
By Marcus Peterson

A film projector projects reels of film onto a screen to form a continuous image. Film projectors have the need to wind and unwind the reels and adjust the arms and distance. Despite the competition from video projection, film projectors have a niche market of buyers.

Film projector rental demand comes from residences, film festivals and university and school campuses.

Film projectors come with different widths such as 8mm, 16mm and 35mm. The type of projector depends on the space available and the number of audience. The demand for 35mm comes mostly from festivals while 8mm and 16mm find demand from other segments such as residences and student shows in universities.

Many of the rental companies are either owned by the universities or reside in the campuses. The demand for film projectors is cyclical as film festivals happen during a particular period of a year. Even for residences, the demand is usually in the summer months, when families like to have get-togethers outdoors.

The rental rates for projectors depend upon the type of films. 16mm projectors have a starting rental rate of $20 per day, 35mm at $50 per day. The total rental rates go up when we consider the screens and other accessories. Most of the a/v industry rental companies hold fewer stocks of film projectors. The rental companies in the university campuses charge lower fees for student groups.

Film projectors face severe competition from video projectors. New technologies such as DLP and audio/video storage media slowly make the conventional film based technologies obsolete. When compared with video projectors, film projectors lack features to control contrast and brightness. Even with cinema halls transitioning to digital forms of projection, film based projector manufacturers are dwindling and therefore are the rental industry of film based projectors.

How DLP Projectors Work?

How DLP Projectors Work?
By Paul Cris

DLP (Digital Light Processing) projectors can be attached with computers, DVD players, VCR players, HDTVs and video games. It comes in various models and with enhanced features. DLP Projectors are also called as Multimedia projectors.

In mid 1990s Texas Instruments developed Digital Light Processing. DLP technology is based on DMD or Digital Micromirror Device. It is a switch, which controls the intensity, and placement of projected light via 4,80,000 mirrors. In a DLP-based display there are unlimited colors. You can control the saturation and clarity to make bright video as clear as you want. The DMD is coordinated with a graphic signal, a light source and a projection lens.

The micromirrors of DLP are fixed on a panel of small pivots, which enable them to slant either way. If it slants towards (on) light source it creates bright pixels on the screen and when it slants the other way (off) it creates darker pixels. When the bit-stream image code enters the semiconductor, the semi conductor directs the switch to on or off. If the switch remains on more times than off, it reflects a light gray pixel. Otherwise it reflects darker gray pixel.

In DLP systems white light is passed through a color wheel and it runs to the surface of the DMD panel. The color wheel converts the white light into red, green and blue. From these three colors a DMD chip can create 16.7 million colors. So a 3-DMD chip DLP system can create a mammoth 35 trillion colors. Then our eyes understand these colors and see an image.
