Are they building a home theatre in a mansion or did they buy a commercial theatre and build a mansion around it? Laughing

You call that a McMansion?!

Around here, that term is associated with large houses (5000-7500 sq') popped up on tiny lots (<1 acre)... usually designed to come within a foot of the adjoining property lines.

Not as pricey as I thought it would be...
Quote:
Building permits for the new, 4½-story house show an estimated construction cost of $5.3 million. That figure, however, doesn't includes many items - such as plumbing, electricity and landscaping - and building experts expect the final cost could balloon to well beyond $14 million.
This probably doesn't include the cost of the land.

I just picked up a BD copy from the Newington, CT Best Buy. I couldn't find it in the Blu-Ray section, and asked a clerk if it was with the regular "Departed" DVD's. She said "no, the Blu-Rays were sold out." After having visiting two Best Buys and a FYE without luck, I was ready to call it a night. I walked out the door and was halfway to my car when another sales girl ran after me and said the first girl didn't know what she was talking about, the BD version was indeed thrown in the "new releases" display. Sure enough, three "Departed" BD's were the only BD's in the entire display!

Two left for someone tomorrow!!!

Hampshire-based AV Solutions company Anna Valley has just invested in the state-of-the-art Hughes-JVC ILA 12k Projector.

According to Anna Valley, the 'large event' marketplace in which they specialize can do no better than the new Hughes-JVC product. With an eye to the approaching Millenium celebrations the company plans to be able to provide unequalled quality of pictures and graphics for event organisers who simply want the best there is.

The projector will offer a superior quality, brighter, larger picture than previously available. Whereas in the past it has sometimes been necessary to 'double-up' projectors to obtain the required brightness levels, the 12K now contains sufficient light in one unit.

In the words of Anna Valley's hire manager Mark Holdway, the 12k is an entirely unique product. Like other projectors in the Hughes-JVC ILA range, it is compliant with all current computer and HDTV standards and reproduces line rates at their true resolutions. No other product on the market can achieve this, believes Holdway.

"In terms of being able to show high-resolution, high quality graphics at their true resolution without re-sizing them or converting them, the whole Hughes-JVC range of projectors has a unique position - and the 12k sits at the top of that range."

The 12k's 7000Watt Xenon Arc Lamp offers 12,000 lumens of light output on screens up to 36 metres wide.

This, coupled with extended bandwidth and a high contrast ratio (1000:1), ensures that the 12K produces pictures which are not only bright but also crisp, detailed and free of distortion.

The 12K's facilities also make it an outstanding choice for fixed, curved screen applications like simulators, planetaria and domed theatres. Even a full 360£ 'theatre in the round'; so says JVC's projector sales manager, Bob Harris.

With image quality of this level on screen sizes of up to 36 metres wide, JVC feels the 12K will be in great demand all year round. Mark Holdway at Anna Valley supports this projection, pointing out that as stage managers and event organizers compete ever more fiercely for the most dynamic visual displays, it will fall to the 12K to meet the demands of their imaginations.

Hughes-JVC Rewrites Cinema History with the Digital Release of Not One But Two Films... and Audiences Applaud on Both Coasts

Hughes-JVC Technology Corporation is adding a new chapter to the history of cinema by ushering in the digital age at two movie theaters in the New York area and two in Los Angeles. General audiences are eagerly standing in line and paying to see a true digital cinema experience, and their response has been extraordinary.

On June 18, Hughes-JVC,s ILA-12K Cinema projector began exhibiting two of the summer's best films, each for a four-week run. Lucasfilm's summer blockbuster "Star Wars Episode 1: The Phantom Menace" is showing digitally in the Los Angeles area at Pacific's Winnetka Theater in Chatsworth and in Paramus, New Jersey at Lowe's Cineplex Odeon. Already shaping up to be the summer's critical favorite, "An Ideal Husband" from Miramax Films plays digitally in LA at Laemmle's Sunset 5 and in New York at the Clearview Chelsea 9. For these screenings only, Miramax is adding a bonus, a special 20th Anniversary compilation of Miramax films.

"Perfecting an Electronic Cinema projector that exceeds the quality of the 35mm film shown at commercial movie theaters has been our goal from day one," said Jack Faiman, Hughes-JVC Vice President of Sales and Marketing. "I am excited to say that we have finally reached that goal. I attended the first night's screening of 'An Ideal Husband' in Los Angeles, and the response wasjust overwhelmingly positive. The industry experts commented knowledgeably on the outstanding brightness, color reproduction, contrast and resolution. But even to the untrained eyes of the regular movie-going public, the difference was apparent. They commented consistently that the images were sharp and clean without dirt or scratches, that the picture seemed richer and more three-dimensional."

Exit surveys confirm these comments: nine out of ten people asked to rate the quality of the Hughes-JVC digitally projected image found it to be as good as or better than traditional film. And the opening weekend's box office receipts revealed that for both "Phantom Menace" and "Ideal Husband" the per screen grosses at the digital theaters exceeded the average grosses at the conventional film theaters. The Digital Revolution has truly arrived.

The projector behind this revolution in Cinema, the ILA-12K, is a production model based on the Image Light Amplifier, or ILA© device. Invented by Dr. William Bleha, Hughes-JVC Vice President of Engineering, this liquid crystal light valve technology is the key to the 12K's unique ability to exceed 35mm motion picture film in every area of image quality, on theater-sized screens. True, lifelike colors and contrast levels exceeding 1500:1 ensure a depth and richness missing with other digital technologies. With over 12,000 lumens of light output and a display resolution of 2000x 1280, the 12K produces a sharp, dazzling, non-pixelized image with the authentic look and feel of film.

Dr. Bleha noted, "The showings of these two totally different films were an outstanding test for the ILA- 12K. 'Ideal Husband' has many closeups of faces and dark scenes where excellent contrast is critical. The 12K's 1500:1 contrast ratio far exceeds not only the limitations of other digital technologies, but also 35mm release prints as well, which are typically in the 1000: I to 1200:1 range. In 'Phantom Menace,' the many highly detailed animations and special effects required extremely high resolution and clarity. In both films, details previously hidden in the projected film version now spring to life on the ILA-12K. We've raised digital projection to a completely new level. And our technology, and the movie-going experience, will only get better in the future. Our next challenge is to exceed the quality of 70mm film."

The JVC is a light valve with 3 CRTs. I used to have a couple of the Ampro versions (the 7200 light valve). And I've seen those JVCs liquidated for $50, but the the power and size make my 242-pound G90 look tiny.

Texas Instruments and Hughs-JVC shed new light on digital film exhibition.

--------------------------------------------------------------------------------
On July 18, 1999, audiences in four U.S. theaters witnessed a revolution in feature film exhibition watching a movie without film. For four weeks, digital projections of The Phantom Menace were presented at theaters on each coast: the AMC Burbank Media Center 14 in California and the Loews Meadows 6 in Seacucus, New Jersey. Both houses utilized Texas Instruments Emmy-winning Digital Light Processor (DLP) in a prototype projector. Meanwhile, at the Pacific Winnetka Theater in Chatsworth, California and the Lowes Cineplex Odeon in Paramus, New Jersey, the Hughes-JVC Corporation exhibited its own Image Light Amplifier (ILA) 12K Projectors.
These presentations—held by Lucasfilm, THX, CineComm, Texas Instruments (TI) and Hughes-JVC—mark the potential for a drastic change from the distribution paradigm as it currently exists. Despite all the hype you hear about digital projection, says Phantom producer Rick McCallum, this technology represents the first real step forward for filmmakers who care about the way audiences see their work. For over 20 years, Lucasfilm and THX have dreamed of the day when viewers could see a film without any loss of image quality throughout its entire theatrical run.

To create the digital Phantom that was used for these presentations, an interpositive was struck from its master negative and transferred to D-5 HD tape at Modern VideoFilm in Burbank, California, under the supervision of THXs principal video engineer, Dave Schnuelle. Two transfers were done, each optimized for the respective projector systems. Colorist Skip Kimball corrected the transfer for the TI projector, and Greg Garvin colored the Hughes-JVC transfer. Both were done on a Spirit DataCine in 8-bit 4:2:2 at 1920 x 1035 resolution. That data was then compressed by the Panasonic D-5 recorder at 4:1 to 1280 x 1024. The D-5 tapes were brought to International Video Conversions in Glendale, California, where a screening room with a 24' screen was set up with three projectors: a standard 35mm rig, TIs DLP, and the Hughes-JVC ILA-12K. The movie was then compared and corrected to get [both telecine transfers and the film print] looking as close as possible to each other, submits Robert Lemer, who represents CineComm Digital Cinema, a company positioning itself to be a satellite delivery service from distributors to exhibitors with digital projectors.

The final HD data was transferred to Pluto RAID disk arrays (consisting of 20 18-gig drives) for presentation at the four theaters.

CineComm represents a key component in the proposed digital distribution paradigm. Were in a position to replace the labs and [the shipping company] in the delivery of films to exhibitors, maintains Russell Wintner, CineComms co-founder and chief technical officer. The film will be given to us by the studio, after which well compress and encrypt it, uplink it to the satellite and address it down to theaters. There, the information will be stored on our Theater Management System, a RAID array totaling about 350-400 gigs that will handle 10 to 12 screens.

The compression algorithm—at 50:1—is a proprietary development by QualComm. It uses an adaptive block size, whereas current MPEG and JPEG algorithms have a fixed block size. That allows our compression to be much more efficient because it compresses an entire frame without regard to the frame before or the one after, as opposed to MPEG, which compresses information based on the differences between the frames. The inherent difficulties of current compression technologies—such as motion artifacts—are eliminated.

The Hughes-JVC ILA-12K projector is based on liquid crystal Light Valve (LV) technology designed by Dr. William Bleha, Hughes-JVCs vice president of engineering. The LV is a spatial light modulator that accepts a low-intensity light image and converts it, in real time, into an output image with light from another source. In the case of the 12K, the other source is a 7.4K Xenon bulb, and the initial low-intensity information is derived from three infrared CRTs—one for each red, green and blue channel. Each CRT raster is imaged onto its corresponding ILA-LV through a relay lens. The Xenon beam is separated into its primary hues with dichroic mirrors, and each beam is linearly polarized by a McNeille-type polarizing beam splitter (PBS) before reaching the ILA-LV. The two sources are compounded together and focused through a lens onto the screen. The raster range of the CRTs can be altered to project different aspect ratios, from 1.33:1 to 2.4:1. At present, the ILA-12K is a 60Hz, 30 fps projection incorporating 3:2 pulldown. The company can later adapt to a 24 fps progressive scan.

The TIs DLP projector incorporates a theatrical lamp housing with their Digital Micromirror Device (DMD) technology, a semiconductor microchip with an array of 1,300,000 tiny aluminum mirrors (SXGA) that act as optical switches by rotating mechanically to reflect light toward or away from the projection lens. The DLP mounts to the front of the lamp housing, and works off the illumination from that source. The light is projected into the DLP, split dichroicly into its three primaries, and then reflected onto one of three DMDs (one each for red, green and blue). A microchip receives information from the hard disk array and coordinates the 1.3 million mirrors, updating their positions. Basically we have a memory under the mirrors, and we load that memory up to 50,000 times per second explains Paul Breedlove, TIs program director for digital imaging. We put a frame of data [from the hard drive] in the memory and break it down into pixels to determine the hue and intensity of each pixel. That hue and intensity is presented by varying the amount of time that the specific mirror is on or off during the period of that frame. The DMD may turn a mirror on and off up to 50,000 times in 124th of a second to get the color shade it needs.

With our technology, Breedlove continues, progressive and interlace doesnt have any relevance. We show an entire frame at a time, 24 fps. There is no scanning going on, so you dont see scan lines. The DLP Projectors have a native resolution of 1280 x 1024, and the 2.35:1 aspect ratio for the presentation of The Phantom Menace was achieved through an anamorphic projection lens.

This revolution is no different from just five years ago, when digital nonlinear editing arose, submits McCallum. The opposition to that was tremendous, but five years later, every studio and every television station has changed their minds. I know [accepting digital projection] is going to be challenging, but the truth is that the future is here—it’s now.


"RAID array totaling about 350-400 gigs"... I bet none of them expected that you would be able to buy 400Gb for $89 today.

An Early History of Digital Cinema Technology

Star Wars Episode I and An Ideal Husband were the first motion pictures to be released to the big screen in digital in June of 1999. Star Wars Episode I was displayed on four digital systems, two in Los Angeles, and two in New York. Two Hughes/JVC ILA-12K projectors, and two early prototype DLP-Cinema projectors from Texas Instruments were used for the Star Wars demonstrations. The digital demonstrations of An Ideal Husband were presented only on the Hughes/JVC ILA-12K. The ILA-12K produced a good looking picture, but was difficult to maintain in a day-to-day theatrical environment. The projector technology of choice quickly became DLP Cinema from Texas Instruments. In the early days, the only projectors available were prototypes built by TI. Today, TI has three licensees: Barco, Christie, and NEC/Digital Projection. TI is the only game in town today, but that could change in 2004.

Let's see, if we assume he's got the ultimate anamorphic lens so he can use the full 4:3 panel area, then he can use the full 12000 lumens. 28' wide would be 441'^2 for a 16:9 screen. 12000 lumens / 441'^2 = 27 ft Lamberts! Yowza. Even if he didn't use any kind of anamorph, and for 2.35:1 he only used 57% of the panel & thus 57% of the lumens, he'd still be throwing 0.57 * 12000 / 333'^2 = 20.5 ftL. Should be enough even for a 103 seat theater!

Just got a PM from Arnold . He is using a Hughes-JVC 12K ILA projector modified by Leo Bassett with a 28 foot screen ! Shocked

Let's see, if we assume he's got the ultimate anamorphic lens so he can use the full 4:3 panel area, then he can use the full 12000 lumens. 28' wide would be 441'^2 for a 16:9 screen. 12000 lumens / 441'^2 = 27 ft Lamberts! Yowza. Even if he didn't use any kind of anamorph, and for 2.35:1 he only used 57% of the panel & thus 57% of the lumens, he'd still be throwing 0.57 * 12000 / 333'^2 = 20.5 ftL. Should be enough even for a 103 seat theater!


Hi Guys,

Your lumen calculations are based on the original 12K model and not the last of the special cinema units. The last units used special ILA panels that were native 16 x 9, had faster response times, superior colorimetry, and much higher contrast ratios. Also important to factor in your calculations is the use of the upcoming HQV line quintuplers. They will take the native 24p H-Def player outputs and convert it to 120P. In doing this the on-screen brightness is increased about 30% over the usual level. The autoranging ability is one of the main reasons I went with the older technology.

Welcome to the forum achase. 120P refresh? Does that smooth the picture out or does it make things look artificial at all?
