Question about Progressive Scan (1 Viewer)

[MikeEckman]

I recently got my first HD capable TV, its a Sony WEGA 32FS420. Despite a few geometry problems, overall, I am happy with it.

Anyway, I've had the same Sony DVP-NC600 5 disc DVD player for about 3 years now. I always assumed I would need to replace it once I got my first HD capable TV since it is not a Progressive Scan player.

I have it hooked up via Component Y/Pr/Pb cables and to my surpise, the picture looks great. I see no artifacting or distortion of any kind.

I borrowed a cheap-o Cyberhome DVD player that did have Progressive Scan and hooked it up to my TV to see if there would be a difference, and I could not notice a difference, either negative or positive with the Progressive scan player as opposed to my old one.

My question is, why am I getting the same quality picture on my old 3 year old non Progressive Scan player as I am on one that is capable?

I do not know much about your specific TV set, but most HDtvs now are equipped with some type of up-conversion/de-interlacer.

The stock answer for this forum would be "The de-interlacer in you TV set is better than the crappy one in the low end progressive scan DVD play you used for a comparo."

Now, you may notice a difference if you hooked up a DVD player with a Faroudja (did I spell that right?) de-interlacing unit. You can get one for around 200 probably. Lots of people recommend the Denon.

Sum it up: Your TV may have a better deinterlacer than the deinterlacer the player was using.

Go crazy.

Thanks for the answer, Adam. I had a feeling it was something along those lines. I think I will stick with my old DVD player until the thing stops working! It does handle layer changes rather poorly though, so perhaps that could be my excuse to upgrade!

First of all, the difference between progressive and interlaced isn't like a HUGE difference. You may need to do more comparing to notice slight differences.

Second, as mentioned, if your TV is deinterlacing 480i inputs, then you are seeing progressive picture in both cases, in which case my #1 doesn't apply, because you're not seeing 480i at all. Then the comparison is even closer, since you're comparing the ability of two different deinterlacers: you're seeing 480p in both cases, so you may not be able to see any differences at all even.

You'll have to look into what your set does to determine whether or not it also has deinterlacing or not.

All Sony HD capable crt sets, direct view or rptv, convert all incoming 480i to 480p, and do it so well that there's no need to rush out and buy a progressive scan player if you currently have a good interlaced model.

So you are seeing 480p on your set, even though your player is not progressive scan.

Even with a really good progressive scan player as opposed to a Cyberhome, you aren't going to see much noticeable improvement over the set's de-interlacing on your old Sony player.

I'd hang on to the present player and only upgrade when BluRay or true HD dvd players hit the market.

Steve:

That's exactly the sort of answer I was looking for when I made this thread the other day:

Mike an I have a very similar TV. I'm hooking a 5 year old Sony player to it, and DVDs look absolutely incredible. I think I'll hold off on upgrading to progressive for a while.
