Here are two papers and articles on DCI.

On the more Dated article by Pinho of Christie which referes to the old dc chip (xsvga) there is a direct comparison of optical characteristics of film and DLP. The summary bodes well for the SuperKontrast MkII to surpass 35mm in every parameter except color gamut. Since this comparison described the maximum possible sequential contrast of 35mm film as 5,000-1, I NOW REALLY believe that this level of contrast IS A CRITICAL BENCHMARK that needs to be reached asap (WITH DCI PROJECTORS AT HOME). See- the prometheus thread for more info on our 3 step contrast enhancing methodology.

Peter if DCI color and gamma were to be added to a high end 3 chip DLP home cinema projector we could see a new level of affordable & manageable performance in the home.

Can a consumer 3 chip DLP be modified to accept DCI content post manufacture?

I actually had the pleasure of having a PM dialogue with some executive of a UHP projector based company the other day who assured me that his color calibration system had the TIP7 essentials in it.

My suggestion to him was to embrace the digital cinema lamp platform, have a tip7 color setup indistinguishable from the one I have experienced in the Barco, and to use the servo zoom lens. I said I would try that projector in a jiffy.

Now in order to see d65 in expanded gamut I really need to see what folsom engineers did on the Barco asc2048 scaler, which we have not hooked up (is just bolted in the rack) while we sort out all the install peculiarities at Helene.

Just haven't had the time, but it will be interesting to see in movies like Casino Royale if the color interscene color dissonance can be tamed under one cohesive hue.

Hi Lon,

Signalwise One is 4:2:0 the other is 4:4:4 but I think some professional non dci projectors do take 4:4:4 so in that regard probably yes. I don't know if the processing speed of the dmd is a factor either probably not.

What is definetly the biggest stumbling block to hooking up a movie server to any no DCI projector is the advanced KEY system. The projector actually comes with a keychain dongle. That number gets authenticated, the sever has another keychain dongle,and both units IP are registered with the distribution houses. SO NO GO THERE.


I still find the tip7 color calibration to be excellent in the Barco, the d65 image is a bit less saturated than what you see in shows but then all of a sudden you will see two vehicles enter the scene and the colors are just perfect. That same scene on a consumer 3dlp is richly saturated throughout but when those 2 vehicles enter the scene the colors are neonized. I just have come to a realization that the correct way (WHICH BY THE WAY ODYSSEY is the only forum meber that has been using it regularly like this for years) is the former, the more filmlike and logically, the one closest to the director's intentions, where color is used to accentuate and add interest to the story.

So probably no go for DCI content on consumer DLP's.

Just haven't had the time, but it will be interesting to see in movies like Casino Royale if the color interscene color dissonance can be tamed under one cohesive hue.

Interesting, the large intercene variation was visible when I saw CR in a DLP commercial cinema. I think we have to consider in the mix also that DCI content isn't always going to be what we get in a lot of ways from BD.

Can a consumer 3 chip DLP be modified to accept DCI content post manufacture?

No, it can't be done. It can't be done in original manufacture by companies like SIM2 either because TI will not license it.

What can be done, provided that there is space for it, is to increase the color gamut by adding one or more filters. There is much more to DCI content than increased color gamut, but that would be a good start if matching content becomes available. Going from 8 bit to at least 10 bit and 4:2:0 to at least 4:2:2 would also be very good steps. These would also allow higher gamma and either eliminate CUE or bring it to an imperceptible level.

The Large mirrors & DCIs proprietary link encryption/decryption are only provided to the big three D Cinema manufactures.

Everything else can be mimic exactly to the DCI spec..color, gamma and more etc as odyssey points out.
