Hi all, I wanted some questions answering re the Hitachi 32PD3000 (applies to the 42" also I suppose) so I asked the kind folks at nexnix (very helpful!) if they'd see if they could get some answers from Hitachi and this is the result:- Q1. I've heard the display doesn't perform best with progressive scan signals but is best fed an interlaced signal instead. This is the exact opposite of other panels e.g. Panasonic that are improved enormously by feeding a progressive scan component signal. Does the ALIS processing give the same results as progressive scan does on other displays i.e. removing of jaggies giving a smoother more filmlike picture? My DVD player uses Faroudja DCDi de-interlacing which is widely regarded as providing significant improvements to picture quality. I feel by the suggestion I'd be better off feeding the Hitachi display an interlaced signal I'm losing that advantage and benefits of that chipset, any comments? A. We have our own Progressive Scan chip built into the AVC box so any interlaced signal is converted by this chip to Progressive scan and is then scaled up to 1024 lines and this is used to create a 1024 line interlaced display on the panel. We think that our chip will give superb results from any interlaced source preferably offered at RGB level. For the enthusiast however we have included a Progressive Scan input on the AVC (tuner box)which means the signal does not go through our Progressive Scan process but is sent straight to the panel. This means the customer has the best of both worlds! Q2. What has been fixed/fine tuned in the tuner box? I asked this question as I was under the impression Hitachi were working on some sort of fix for a problem but it seems that wasn't the case, anyway... A. Not too sure what he means by this but the I2 chip has Dynamic Contrast which automatically monitors the picture content and increases the dynamic range so giving better blacks without reducing brightness. We also have a feature that constantly looks at 3 fields of information and looks for unwanted noise which is then removed. At the same time it uses these 3 fields to look for moving objects and calculate on the interpolated lines where the object should be. This results in much smoother motion. We also have 3/2 pull down which improves the motion quality of NTSC discs. Q3. Why does the display subjectively look so bad with an RGB feed from e.g. Sky Digital but look so good with DVD? I don't understand what the difference is to be honest but I've seen the display in a store with Sky Digital material and it didn't look very good with what seemed to be scaling artifacts and combing artifacts visible. Is there any way to improve the quality from Sky and what explanation is there for it being so poor compared to DVD? - I have to say I was only going on what I'd seen in Powerhouse here (not the best viewing conditions granted) and also comments by people on the 42" no tuner box version. A. I have seen excellent results with Sky Digital when I presented to UK journalists they said it was the best Sky picture they had seen on any product. One problem maybe the channel they were watching. For best results watch SKY news or BBC News 24 and wait until you see a studio broadcast. If you have the opportunity watch Sky Sports football as this is now mostly broadcast in true widescreen format. RGB should look much better but remember it will also show up the defects of a poor signal. Generally Studio broadcasts on the channels I mentioned use a bandwidth of over 5Mbps but this can drop considerably for out side broadcasts. Q4. Is the ALIS processing the latest generation which has apparently improved since early generations? What improvements have been made? A. The ALIS processing is the latest version but it basically refers to the system of using separate electrodes for odd and even fields. This results in a vertical resolution of 1024 lines whereas 480 is the best a VGA panel can manage. The 12 chip we have developed makes full use of this by actually creating 1024 lines in the processing. In the previous model we could only create 512 lines in the progressive scan process. Hope someone finds that interesting/useful. Cheers, Andy.
