The reason I ask is I am trying to establish how good the Sony deinterlacer actually is, and weather it can do 3:2 pull down and weave deinterlacing of film sourced video.
Its hard to believe the Realta processor will show any advantage with film (progressive) sourced video.
I do expect the Realta processor will show some advantage with true interlaced (video camera sourced) video, but just how much advantage will be interesting.
Do all SXRD's suffer from color uniformity issues, and just how noticeable is it?
If its no more noticeable then a CRT RPTV with lens strips applied, it's not significant to me.
I have not had a chance to do that specific comparison, but I do have the ability to test Sony deinterlacers. I would say they tend to be generally of fair quality. They are not horrible, but they are not spectacular either.
Where the Realta really shines is on reducing MPEG compression artifacts. They also have some great video deinterlacing. Sony is not putting this level of processing in their sets at this point. Once you have the ability to resolve MPEG artifacts they become pretty distracting. I find the Realta processing very useful in its ability to smooth these problems out during motion while not reducing sharpness when the image is stationary when their algorithms are used properly.
Sony's film mode detection is decent. That is not where I would expect the majority of the benefits.
All SXRD/LCoS sets I have seen have color uniformity issues. This is what William Phelps corrects on JVC and Sony projectors. I find it very noticeable, but I have the advantage of seeing many display types using the same reference quality inputs. Color uniformity across the screen can be worse than CRT or about the same it depends on how poorly the particular sets polarizer is aligned.
Gray scale tracking problems are much worse than CRT from 0 to 5 percent input signal levels with SXRD. One manufacturers LCoS display technology has gray scale issues as high as 25 percent input signal levels. The panels tend to run very purple or red when they have problems at low levels.
I am a big fan of SXRD, but these displays are not perfect either.
