The 810 video processor can accept SD and HD resolutions up to 1080p60 according the basic spec sheet you can easily get straight from the Meridian website. The chipset they are using is something I haven't heard of before, but when I checked out their website a couple of weeks ago I must admit I was very impressed. The 810 scaler uses FOUR Qdeo chipsets for deinterlacing and scaling the image in effectively four quadrants which is put back together by a fifth scaling chip inside the projector itself (hence the 4 DVI connection). The specs on the Qdeo seem to cover more than just the basics:

- Advanced per-pixel, motion-adaptive, edge-adaptive 3D de-interlacing for HD and SD video, with support for arbitrary film cadences
- advanced per-pixel, motion-adaptive, spatio-temporal noise reduction for HD and SD video
- Content-adaptive block and mosquito noise reduction for HD and SD video

plus a bunch of other gubbins. Short story long, from the day I spent with the 810 system a couple of weeks back I am VERY impressed. You could feed 1080p from an external video processor into the 810 scaler which would in turn scale to 2400p and apply any enhancements you wanted to use, but I'm not that sure it's going to be necessary. From what I saw from SD and HD sources there was no deinterlacing artefacts getting in the way (admittedly all film material) and the scaling was mostly excellent, certainly no painful edge enhancement or obvious softening of the image whatsover. I did spot some scaling artefacts in very high resolution detail, but the unit had literally that morning been installed with a beta firmware which had brought about a couple of other problems so I give it the benefit of the doubt for the moment. I will certainly want to see this projector again (and the scaler). If any Meridian heads are reading this - get yourself a decent 2.35 system in that theatre ASAP so I can see it in all it's glory!

Website for the processor chip I have been reading from:

They seem to supply quite a few brands such as Pioneer and Sharp, but I guess so do Gennum and HQV the implementations of which vary wildly according to quality of integration. Interesting that Home Theater Secrets gave them an award for best video processing solution last year....
