There is an interesting article in this weeks US News and World Reports. On page 54, the article goes into digital home theater projection systems. It talks about a guy in Budd Lake, NJ that put together a 8x19 foot screen digital system using a Sony Q video projector for about $3600. It also talks about a new system by Sanyo. It's a $9000 digital projector number PLV-60T that can throw a 48 feet wide screen picture from any digital source. That right, 48 feet and this is for home use. If all this is true and not a misprint, then theaters as we know them will be doomed. Larry

US News article on home theatres While I agree that the real competition for theatres in the future will be affordable high quality home theatre systems, I would take some of the hyped claims and inflated specs with a good dose of SKEPTICISM and a grain of salt.  A 20 x 48 foot image would require a pretty big house! And I doubt that $9000 will buy you a digital projector with the 11000 lumens needed to light a matte white screen of that size to even the minimum 12 footlamberts. BTW, that Sanyo PLV-60 projector has a rated light output of only 1300 lumens, which would light that 20 x 48 foot screen to a little over 1 footlambert:

I agree that 1 footlambret with a 20 x 48 foot wide screen is no where near the minimum and would not fit into any normal big house. Since brightness increases 4 times with every 1/2 reduction in screen size, a 10 x 24 foot wide screen would have 4 footlambrets and a 5 x 12 ft wide screen would be a bright 16 footlambrets. Perfect brightness for home use. Maybe even too bright. Larry
