Progressive scan DVD units can they play interlaced SCVD's?

[hardwork12]

When I look at the units that are listed as great compatibility (like many of the philips) with CVD, SVCD and especially XCVD and XSVCD (high bit rates)
they seem to be progresive scan units.

My question is that the CVD and SCVD's are Interlaced so isn't this bad for playing these sources? I am not sure.

I also never owned a progressive scan unit so these question are going to be dumb. Many of the compatible units state progressive scan and also have component video outputs. I use the component video outs to my TV and when I play a DVD it comes up as a 480I source. Does the progressive scan also use the component video outputs or is the progressive scan hooked up differently?

Do the units with both a component video out and progressive scan capability actually capable of both interlaced 480I playback and 480P playback ? How can both be hooked up at the same time if the unit does in fact support both?

Thanks ALL

they play all interlaced source just fine ... or they would be rather useless to purchase ..

To view progressive movie, you need the DVD player and TV to be both progressive. Or else you not going to see any meaningful picture.

The TV does use component ( 3 RCA ) connection, but it is a different spec : known as HD or Progressive or 480 P.

If you do not have progressive TV, if you are just for versatility, and the philips are not much more expensive, go for it, that one less item to deal with when we goto HDTV.

Else, you are not getting any better video, just able to play most type of format. There are pioneer and JVC players that do a very good job on versatility too.

I took a look at the specifications of my TV which is a Sony KP-53HS10. It states that it is capable of 1080I, 480P and 480I but specifically states it will not work with 720p (no idea what this is).

So I guess I can use progressive or not. Is there an advantage of progressive over non-progressive?

What happens when I play an interlaced or non-progressive CVD or DVD? Will the picture quality be the same as I see now with my 480I non-progressive scan DVD player?



Thanks again

Yes! Non-progressive video has alot of 'artifacts', like combing, moire, flicker, jaggies. They look much worse with larger TVs. A progressive TV will always make the picture look better, and often improve the vertical sharpness as well.

Well, first, nearly all video on DVD is actually stored as interlaced, meaning every 'frame' is actually stored as 2 smaller frames. However, if the source is from film, and 24fps, then the DVD player can combine these 2 frames and create the original REAL 720x480 frame. A progressive TV can not do that since it doesnt have access to the original digital frames, but guess do a pretty good job at faking it.

So, it doesnt really matter if the mpeg2 is encoded as interlaced or not since your DVD player is designed to convert it to the proper format.

Sometimes however, progressive (bob) video can look to blurry, not sharp enough. That depends on Tv though as the sharpness can be adjusted.
