3:54 am	Experience Cinema at your home Not so long ago home movie nights consisted of a rental video and a bag of fruit gums. Today, with advances in technology, you can take a trip to the pictures without leaving the comfort of your home. With a professional home cinema installation you can enjoy movie night every night of the week. The quality audio system is achieved with a high fidelity surround sound system. It contains at least 4 speakers as well as a subwoofer in order to have the proper sound effects. The definition for HDTV image is 1920 x 1080 pixels. Producing a large image from a projector having a resolution of less than 1920 x 1080 will give poor results. The pixels, making up the image, will be apparent and the image will not appear sharp. data projectors will typically display as XGA 1024 x 768 pixels or WXGA 1280 x 768 pixels. With the introduction of the latest DLP HD 1080p projectors, the competition is being left in the shade. Experience Cinema at Home With both home theatre and business projectors, the environment you will use the projector in should determine how bright you need it to be. In the home, you will most likely use the projector with the lights off to simulate the movie theatre experience, so your projector doesn't need to be the brightest on the market. However, the brighter the image the better, so if you can afford a brighter projector, it is always advisable to go as bright as possible. With the growth and rapid increases in quality of home cinema systems with the introduction of Blu-ray and HDDVD players along with high definition broadcast, viewers are becoming familiar with the superior quality of digital projection. Sony supplies digital projectors into cinemas and is currently the only company offering the higher resolution 4K unit. "The aim is to differentiate cinema from the growing number of HD home entertainment systems by delivering equipment that meets the DCI's forward looking 4K standard. With four times the resolution of HDTV and the equivalent 2K standard, audiences can enjoy a more immersive experience. We have already supplied our systems in volume in the US and it is interesting to note that recent restorations of classic films are being carried out at 4K so the format is becoming a de-facto standard," said Mark Clowes, head of Cinema for Sony. To take it to the next level, you might consider putting your home cinema in its own ‘cinema room’ (sometimes called a ‘screening room’), complete with sound insulation, a screen for a projector and extra-comfortable cinema-style seating. Some enthusiasts go as far as to decorate this room to look like a cinema, with red curtains, movie posters, and a popcorn machine. If you do go this far, then you don’t have to keep the home cinema just for yourself - you can invite friends over to enjoy it too, and even hold screenings of particularly rare and good films.

3:28 am	Move the Cinema to your Home Every year, while movie theater ticket prices go up, HDTV prices come down. That gives the home theater two big advantages: convenience and affordability. At home you can watch what you want, when you want, and movies are making the journey from the silver screen to DVD or Blu-ray faster than ever. In low to middle-end projectors class (from 600 to 3000 USD) DLP vs LCD question is still highly discussed by projector users and buyers. For that price you could get 1 chip DLP projector or LCD (or so called 3LCD) projector. It depends on exact purpose of projector. Cheapest DLP projectors might produce so called rainbow effect, but not every user might see it. Rainbow effect appears in dynamic sceens (movies, video games etc). This rainbow effect ir highly dependent on the speed of projector's color wheel. The higher color wheel speed - the lower possibility to experience rainbow effect. We recommend to choose projector equiped with 4x or higher color wheel speed. Despide this disadvantage of DLP projectors, only DLP projector manufacturers can offer "3D ready" projectors equiped with DLP Link technology, which are suitable for your 3D content or 3D video games. LCD projectors can not offer that at the moment. These are the main differences, but there are a lot more: DLP projectors usually are brighter, but produce more noise in most cases; DLP projectors can produce deeper blacks and reproduce more natural colors (but it highly depends on the manufacturer and quality of particular projector model), but in some cases LCD projectors can offer higher contrast ratio, smoother motion scenes. So if you already decided on the budget for new projector, we recommend to read users' reviews of particular projector models. A projection screen is a special screen used to project an image for the audience. Used in conferences as well as in home theatres, a projection screen serves different purposes in different places. They come in a wide range of varying quality, size and gain. A Home Cinema setup is slightly complicated and involves buying additional equipment and speakers. So if your wife already looks at your equipment as an eyesore, please stop reading and shelve the idea. Screen gain expresses the brightness of a given area in relation to matt white. Magnesium carbonate is used to represent “standard” matt white surfaces, according to standards set down by the German Institute for Standardization (better known in the U.K. as “DIN”). We therefore use magnesium carbonate as a reference material for our measurements. Generally, small scattering angles are associated with a high gain factor. home cinema system Brightness is very important in a corporate setting as you will want to keep the lights on during a business presentation. Projectors used in areas with high light require a much brighter output than those being used in a dark auditorium or lounge room with the lights switched off. You should consider whether your projector will be used mostly for text or for video. Text requires high clarity to ensure the entire audience can read the contents and that requires a bright projector. With a video presentation on the other hand, you can generally get away with a slightly lower brightness as every single detail is not quite as important. Also think about the size of the room you are presenting in. A small conference room can get away with a 1500 lumen projector, whereas a large room may need 2200 or 2500 lumens. The more people that are being presented to, the higher level of brightness you will need. At its most complex, you can have a custom-built home cinema that costs tens of thousands of dollars with a high-end projector, DVD player(s), separate amplifiers for each channel controlled by a master preamplifier or controller, in-wall speakers, and a couple of subwoofers. Your home theatre can also be something as simple as a screen and a "single box solution", a one-box DVD player and amplifier such as the Naim n-Vi. Once you've gotten them home, the cinema systems are so easy to set up, you'll wonder why you didn't invest in one earlier on in life. They all come with easy-to-follow guidelines and instructions, and all the cables you need should be included. (Comment on this)
