REDray Projector..

[Michel Hafner]

This projector needs to achieve JVC contrast and blacks for me since I'm a black 'fanatic'. Actually I hoped it would be a scanning solution with zero light for black. The first projector to make credits look like letters are floating in a black hole with no support whatsoever. That seems to be as elusive as ever, though. If contrast remains low I'll have to wait for it to improve before I could use this projector. I want something like 100000:1 and better.

Contrast will improve significantly from what was seen at NAB - especially if you saw it on Monday rather than Tuesday.

This question highlights one of the major advantages of the modular design we applied to the projector.

Traditional designs place the lamp in the projector head, it gets hot, and hence you need to put substantial cooling (fans) there too.

In our modular design, the "lamp" is in a rack mount chassis that can be located a considerable distance from the optical head.


So no "projection box" needed.

Stuart, I agree this is a great feature.

Question: Is the projection head totally silent and fanless, or does it still contain one or more fans? If it has fans, please keep in mind that for home theater, even subtle humming or buzzing really kills the atmosphere.

Also, I didn't go to NAB, but I looked at some of the photos taken there. It looked like there were HDMI inputs on the back of the projector. I wonder if you have considered putting inputs onto the light engine box. It would be wonderful to be able to make an HDMI connection right in the equipment rack rather than running a long, expensive and trouble-prone cable out to the projector.

I really am interested to see this machine in person. It's still not a viable option for my house at this time, due to the requirement for a special screen for 3D. Perhaps someday, but not soon, since I just bought a new screen.

You know Stuart, I'm glad you guys are targeting small theaters. I was pushing for Red to do this before, like to see the little guy helped out. Why I'm at red user, to see Red customers getting good value.

Still, again, how does this projector scan, and any hope of putting in vesa hold frame feature, and vector commands data channel to frame buffer (or scanned if possible) for graphics in light shows?

Do we need lasers to do this job, don't phlat leds offer most of the monochromatic advantage at higher energy efficencies?

[Ben Price]

High output LED's can do the job and have before. I have seen prototype LED powerd projection systems that people here in the US thought worked great but was shot down when shown to a group in Japan, interesting really, it was a differance in color perception that some in the test group felt was cultural possibly. but basically it was metameric failure. i think this can happen with any imaging system that uses too narrow of a source spectrum.

Yes the Display (light modulator and optics) Module is specified to be silent. Auxiliary video inputs plug into the rack mounted Video Processor (REDray player and audio / video circuits) Module which relays those as 4K images to the Display module.

Thanks Wayne. If we can help our customers win, we win too. It's all good.

You guys should reach out to IMAX, seems their laser system is a little behind...

Yes, bit off, I was not thinking of their power limitations for something of sizable size. But this shift in the color frequency of oerception is interesting. Across people ina race there should be a shift among individuals, I have a shift between both my eyes. So between diverse races it would be interesting, do we need to specify a minimum spread of frequence for each primary? This might work if there is a problem, and easier than what I am about to suggest, because it might still lead to imbalances. The other solution is to have a group of frequencies, which means seperate bands for each color, balanced so that, at least, the majority of individuals perceive color with more accuracy, due to not individual bands for each group, but balancing between the bands, where the bands may not even be at peak, but positioned so the energy of all bands accumulates to better color for the majority (if not all) of groups. Tricky, but you can just change the frequencies for each region, which might not require a change in recording frequencies (wishful thinking) but of the projection. Here we have another problem of film recording that is probably ignored, but I have contemplated systems that sensor capture a range of frequencies and model a recording of them for latter use. But now a more ideal system comes to mind, and yet another to capture on sensor. I actually previously did come up with a way to record a so read of frequencies seperately, exciting times those days.
