Question about playing interlaced DVDs in a progresive scan DVD player

[numlock]

I read somewhere that in order to get all the benefits of progressive scan DVD player you need to have a progressive TV also (such as HDTV).

My question is what if I have both a progressive scan DVD player and a progressive TV but the DVDs I'm playing are interlaced. Will I see any improvement ? I highly doubt.

Hi-

I read somewhere that in order to get all the benefits of progressive scan DVD player you need to have a progressive TV also (such as HDTV).

And to hook them up using Component cables (or DVI, if available). But without a progressive display, you get no benefit from a Progressive Scan DVD player, as you'll still be outputting 480i.

My question is what if I have both a progressive scan DVD player and a progressive TV but the DVDs I'm playing are interlaced. Will I see any improvement ? I highly doubt.

Any improvement compared to what? Your old interlaced TV set? The quality of the picture will depend on the deinterlacing chipset used in the DVD player or the HDTV. In general, though, I'd say you're right. Progressive displays are at their best when being fed from progressive sources.

Hello manono,

I have a question:
If degrees of algorithm of deinterlaced exist, what final value can again give a DVI hold or HDMI?
Supposing that it is true several versions of scaler iScan would exist then in HD+ version.
Because apparently, the DVDO works on a new system of high-quality deinterlaced.

Some precisions would be very useful for me.

Hi-

If degrees of algorithm of deinterlaced exist,...

Yes, of course there are degrees of deinterlacing quality among the Progressive Scan players. Most aren't very good. I've read of people that watch their progressive movie DVDs on the HDTV, and their interlaced concert or TV show DVDs on an interlaced TV, because the quality of the deinterlacing from their cheap Progressive Scan DVD players is so bad.

...what final value can again give a DVI hold or HDMI?

Depends on the algorithm used. My player and HDTV use Faroudja deinterlacing, and it's supposed to be one of the best, but I can still easily tell when something is being deinterlaced. That is, there are still artifacts. iScan is also supposed to be very good, but unfortunately I don't know what method it uses to deinterlace. I'm sorry, but I can't give you any precision. Maybe someone else can.

For more on the different deinterlacing methods used by Progressive Scan players, there's some information here:

You're looking for the topic "Video-Mode Deinterlacing", about half way down.

Manono,

I am impressed by this analysis deepened of the deinterlaced or rather of the "re-interleaving."

That's which allow me to note that the ideal would be to have a progressive Scan player + a spotlight (Faroudja or a Barco) + a scaler capable to convert it (1080i in 1080p) with a compensator of movement with the application of the 3:2 pulldown and an exit of RVBHV type.

I didn't finish my reading because there is a lot of thing to see.
Thank you for this precious tools on "re-interleaving".

To soon ;)

I'm currently using a Pioneer DVD-575A (with a manual "progressive output" setting) connected to an Hitachi 42PD5200 plasma via component YUV (YPbPr).

When I play Mpeg2 (or Mpeg4) 25fps or 30fps interlaced content, the player displays it as interlaced, even when the "progressive output" setting is switched on.... Which is nice!

Maybe DVD player owners connecting via VGA, DVI or HDMI are not so fortunate and don't get choice of watching interlaced content in interlaced mode. I hope to know more soon, as I'm hoping to be testing an high-def/res DVD player with HDMI within a couple of months...


Cheers

Hello,

While browsing this manual of the deinterlacing, I noted that there was not perfection of the picture, but just an approach of the ideal.
The element that is different of this survey remains the constant improvement of the capacities to distinguish the imperfections of the treatment, has various shortcoming dawned of the analysis of the luminous signal.

All rests on the degrees of the algorithm of the deinterlacing (chipset, Scaler, spotlight..) and to finish the accessories of transfer (entries and exits, connecticuts....)

Its as HIFI, the source is the master of work: the player or drive + converters, then amp and the préamp (to lamps, transistors or hybrid), then the speakers and finally the cables sector, HP and of modulation + the filters sectors.

Seemoredigital, the DVD player's name is it in my pack: Meridian, Ayre, Linn, Accustic arts, Bel canto, Pioneer or Onkyo.

To soon.
