4K DLP chips are shipping today, according to the Texas Instruments Press Release. The three authorized OEMs, Barco, Christie and NEC will now be able to ship the digital cinema products which their catalogs now call 4K ready.
There is some data missing from the PR. For example, Barco is advertising that there are two sizes of 4K chips expected, one to match the 0.98″ C range projectors, and one to retrofit the 1.2″ B range projectors that they offer in their product line. (Christie and NEC only mention retrofitting the 1.2″ chip versions.) We believe that what TI has just released is the 1.38″ 4K chip, which will retrofit into the three 1.2″ positions in the larger Christie (CP2220 and CP2230) and NEC projectors and the B Series Barco projectors.

The DCIMovies website now lists 3 NEC, 2 Chrisite, and 3 Barco projectors as having passed the Compliance Test Plan detailed procedures. All 3 manufacturers are utilizing the same version of the Texas Instruments (TI) Enigma board and what appears to be similar versions of software. Details are on the linked site above.
Christie Press Release Barco Press Release NEC Press Release
Christie has just announced that their CP 2220 Series 2 projector has passed muster at CineCert for DCI Compliance. The sentence that says that they are the first has me in an infinite loop, which prevents me from reading any more. There is probably some nuance that says that they did something that Barco didn’t do, but who knows…the rest of the press release just seems so release-y after that.
This document is Part 0 of an multipart article that details with the basics of today’s transition from film-based cinema to server/file-based digital cinema. This Part 0 addresses some questions that came from readers of Part I, which explains its format and style.
Imagine a rainbow or the light that comes out of a prism. What we think of as the white light of the sun gets split into several discreet, or separate colors.
The next time that you are outside on a sunny day, notice the different shades of blue in the sky as you view it closer or further from the sun. Then later in the day before sunset, notice the colors of the blue as it ranges from deep to light blue and starts to turn orange and then several other shades of red.
There have been a lot of studies that deal with color, and how the human visual system deals with it. There is an international center, the CIE, for all things color and illumination. They did basic work early last century which tried to answer several questions about what an average group of people actually see. They helped settle on methods to scientifically speak about color, and on the best working theory for how the eye (in general) and humans (in particular) see (in general) and see color (in particular.)
