Genesis/Sage/Faroudja vs. Silicon Image
These two chipsets are clearly the best available right now for progressive DVD applications, and the question often comes up of which is better. Unfortunately, it's not a simple answer. For video-sourced material, the Genesis has the better picture with fewer obvious jagged artifacts. The DCDi™ processing can really improve difficult video signals. It's not a panacea, and it can't make video look like film, but it does improve things. That said, the Silicon Image video deinterlacing is very good as well. But we'd have to give Genesis the edge here.
In film deinterlacing, the two are also very good, though they each have their strengths and weaknesses. The Silicon Image is better at staying in film mode when there are hiccups in the 3-2 cadence, which is good because is maintains the full resolution as much as possible. The Genesis chip's tends to go into video mode more often and stay there longer. Because of the DCDi™ processing, it's not always obvious when the Genesis goes into video mode, but careful attention to the high-detail areas of the scene show that the Genesis chip does tend to drop into video mode more often.
Because the Genesis chip goes into video mode more often, it is slightly less susceptible to combing, because at the first indication of combing, it immediately goes into video mode, and stays there until the cadence is clean again. On the other hand, during the time it's in video mode, the viewer is losing much of the fine detail in the scene. We found quite a few films that tripped up the Genesis, even though the cadence was fine. On most of these, the Silicon Image would stay in film mode the whole time, but the Genesis would drop in and out of film mode.
We've done extensive testing on the 2-2 pulldown performance of the two chips, and it's clear that the Silicon Image is much better at detecting 2-2 pulldown and staying in film mode with 2-2 material. In its default configuration, the Genesis doesn't have 2-2 pulldown enabled at all for NTSC, though it is enabled when it's in PAL mode. Even in PAL mode, the FLI2200 doesn't do quite as good a job at properly detecting 2-2 progressive. On the flip side, though, the Silicon Image combs more often on video material, because it more often incorrectly identifies video as 2-2 progressive. This just serves to highlight how difficult it is to always 'do the right thing' in deinterlacing.
Still, much of this is splitting hairs. Both of these chips are excellent, and in our view represent what you should expect from a progressive DVD player. Either one of them will deinterlace the vast majority of discs with no noticeable artifacts. If you watch a lot of video sourced material, or you want the chroma bug hiding or cross-color hiding features, the Genesis is probably a notch better. But for film sources, it's a tossup, with perhaps a slight edge to the Silicon Image.
