DVL-Digest 934 - Postings: Index Best DV Projector Best DV Projector - "Perry" My, things have changed a lot over the last few years! I saw this strand and thought I would investigate a little. The Texas Instruments DLP chip system seems to be rolling up the whole market, from tiny desktop units the size of a paperback right up to these movie theatre monsters. TI themselves have set up a marketing division to promote Digital Cinema. On their web site (http://www.dlp.com/dlp/cinema/faq_q7.asp) they state: >During the first half of 2000, we announced three companies with whom we will be working to develop, manufacture and market commercial cinema projectors based on DLP Cinema™ technology: they are BARCO, Christie Inc. and Imax Corporation.< (Imax own a company called 'Digital Projection') and later: >For the foreseeable future, we expect to work with only these three companies.< The Panasonic projectors that Jan mentions also use a DLP engine, so I don't know why they don't get a mention? The old JVC-Hughes monsters have disappeared, but a new range based upon the D-ILA engine go up to small theatre size. There is also a US company called Colorvision with a laser based system of similar power. I had understood from IBC a couple of years ago that Eidophor were to make a come back but I see no sign on the Internet. For newbies they used to make the grandfather of all large video projectors. It was based upon a 'light-valve' using a rotating drum covered in an oil film that was then bombarded with electrons scanning the image. This distorted the oil film and this was used to bend a light beam and via a dispersion grating modulate the light output. The monochrome original was rather grand, but the color version with three light valves was the size of a small garden shed and weighed about the same as one filled with several motor mowers!
