Deinterlacing quality a myth?

I wouldn't say is nothing because there is a difference because most likely you may have missed something during your tests and observations(I assume you have progressive mode enable on your 56).


At home, I have the Panasonic DVD-A470EN, 56 and 82 and can see the difference easily on all three. I tested them by watching DVD anime(you can tell instantly with this) or movies. They were all hooked up to my Hitachi TWX 57" widescreen.


I have also tested the same 3 units on a Panasonic direct tube TV(has no component or progressive) and I can also see the difference using composite video input.

I'll just add this comparison for Panasonic units here as a reference.

You need to play something that is poorly authored for the difference to jump out at you. With properly authored stuff, the differences in players can be very subtle.


If you have kids, play 101 Dalmatians II (this is animated) on a player with poor deinterlacing, then on a good player.


My Pio 45a is a flag reader, and this title is improperly flagged. On the Pio, the combing I get on this title is unreal.


Play the same title on my Denon 1600, and its clear, solid, and not a combing artifact to be seen.


I am sure others can suggest some additional poster children for poor authoring.

I own a Toshiba 57HX81 and have 3 progressive scan DVD players (only two at a time are connected to it) and I can definitely see a difference between interlaced and progressive video feeding my TV.


The one point that no one seems to have addressed is expectations. What might seem like a "drastic" difference in picture might seem like a subtle difference to someone else. I'm not sure what people expect when they read messages about the "marvels" of progressive scan video so I have to wonder if sometimes people develop higher expectations than they really should.


I wasn't sure what to expect when I watched my first DVD played back on a progressive scan DVD player but I was sure impressed with the results. If people are thinking they will automagically see a "night and day" difference in video quality just because they have a progressive scan DVD player connected, perhaps their expectations aren't what they really should be.


I don't know what other's tastes are in video quality but I can say for my own personal experience, I've noticed a definite difference between interlaced and progressive scan video on my TV. My mom, who doesn't know anything about HT gear at all, even noticed a difference when I did a quick interlaced vs progressive scan comparison with her as the judge. She preferred the progressive scan picture but not necessarily for the same reasons people tend to mention most on sites like this.


Peace...

The players de-interlacing still is a major part of the overall image quality even if your TV is scaling to 540P, as many RPTVs do. The TV isn't doing ANY de-interlacing if you feed it a 480P signal, it is just scaling. If you sent it a 480i signal, then it would be de-interlacing as well.


De-interlacing is one of those things that some people are more sensitive to then others. At Secrets, we came up with the best tests we could and gave lengthy explanations on what was happening with each error.


There is a huge difference between some players when it comes to de-interlacing, but you need the right material to really show the benefits.


If I was reviewing display devices that de-interlace the image I would run the exact same tests on it as we do with DVD players. But I don't really review display devices. I know when I bought my NEC plasma I ran the de-interlacing tests and it did brilliantly. Passed everything the high end de-interlacers pass. The Faroudja still does better with video sources though with its DCDi processing.

Kris,


My Sony 61HS10 will upconvert 480i to 960i using Sony's infamous DRC system.


Am I better off with 480p signal from Sony DVP-CX777ES ( which passed Faroudja tests according to Secrets) ?


It is a $64,000.00 question for me (well, maybe just $640 )


Thanks a lot.
