Your old analog TV most likely uses interlace method to draw the images on the TV. That means that the electron gun in the back of the TV shoots off odd lines on the screen first, and then follows up with the even lines. That usually occurs very quickly at about 1/30th of a second, but sometimes you see an ok picture with some flicker.

So to improve the picture, projection TVs are using line doublers. They turn the interlaced NTSC picture into a progressively scanned image by doubling the number of lines on the screen. Thus you can understand the name line doublers. Haha. So the scan lines that make up the picture are less visible and the images appear more solid.

Mostly al HDTVs can draw progressive scan pictures. They work the same way your computer monitor works. It writes one full frame of video from left to right across the screen every 1/60th of a second. Since the entire image is drawn at one time, the picture looks more stable and cleaner then an interlaced one. They also have fewer motion artifacts, such as jagged diagonal lines and movement in fine detail.

The progressive-scan dvd players will only work with digital TVs and HDTVs and don't work with old analog TVs because of their higher scanning frequency of 31.5kHz. A big feature of a progressive scan dvd player is the 3:2 pull-down circuitry. It smoothes out the picture and virtually eliminates jaggie artifiacts.

The other big reason why progressive-scan DVD players deliver much better pictures is because they can read extra data tags on DVDs and the players can work their image-processing magic in the digital realm before they output the video signal in analog form. Because of this reason, a progressive-scan dvd player can deliver a sharper and cleaner picture.

how do I know my dvd has progressive scan?
if it doesn't say, then it doesn't have it?

it should say in the User Manual/Box. However, your best bet would be to check on the manufacture's webpage. How old is ur DVD player? If it is more than a cple years old, chances are its not, unless you paid big bucks for it. In the beginning, Progressive Scan players cost a lot more that regular players, however, they have come down in prices now. I just picked up a Toshiba SD-3900 (Progressive Scan) for $169.99 CDN and its an amazing player.

so even if my tv as component input doens't mean it will work with progressive scan right?

Correct. My Toshiba 27A43 has ColorStream (AKA, Component Video) but, because it is not an HDTV set, it does not take advantage of the progressive scan. Personally, i find DVD video quality amazing, even without the progressive scan.

i need a hdtv or some other digital display.
right.

hope this helps.

dude... i don't think your TV will take advantage of the progressive scan feature of a DVD player...
check the specs out @ toshiba.ca

Its not an HDTV, just a PureFlat regular ol' TV. Still, its one of the best TV's out there! Even consumer's reports say so!

Cheers!

I recently got a 57" Hitatchi RPTV HDTV Monitor... Now its HDTV Ready, so will it take advantage of the progressive scan DVD player? or does it also require you to have an HD tuner/receiver?

Thanks!
