Progressive Scan?


Recommended Posts

I saw on the back of my PS2 games I bought Jak2 and Ratchet and Clank going commando it says progressive scan as one if its features. Also i know the newer PS2s come with progrssive scan and I was wondering what is progressive scan and what does it do? :blink:

Thanks,

I get this question alot at best buy, where I work. Without diving into details, progressive scan reads through the image output multiple times to gives a clearer more accurate screen image.

Google is your friend

Its only of use really to NTSC systems which have less lines to their picture compared to the rest of the world (PAL and SeCAM)

I'm not sure that progressive scan does much for normal CRT televisions but you can read more about progressive scan here:

Progressive means that the screan is drawn all at once in one shot. For example, you have interlaced TVs that if you go up really really close to them, you see white lines between each line of video.

Whats happening is that every off line gets drawn, then all even lines. They get drawn back and forth really fast and you see TV images. Progressive everything is drawn at once. Its clearer. You need a progressive scan TV to be able to utilize the progressive tech on the games. They even have progressive dvd players.

Usually, high end flat HDTVs have progressive.

Whew. Lots of replies and only one decent piece of information.

Progressive scan is, as redFX said, when the output device sends the picture out, frame by frame, in one shot, exactly the same way your computer sends it to you monitor.

Normal NTSC transmissions are interlaced. I'm not going to go into detail as to why, but it's because of the original black-and-white TV technology. This means that for every 1/30th of a second (one frame of video), the first 1/60th of a second has the odd lines, the next 1/60th of a second has the even lines. If there's camera or object movement in that 1/30th of a second, you get this horrible stipple pattern in the image.

With progressive scan, every frame of video (1/30th of a second) is sent in one shot.

All HDTVs handle progressive scan. They have to because it's part of the HDTV spec.

Also, you need component inputs for progressive scan. If all you have is S-Video, you're not getting progressive scan.

Apart from the more solid picture, component video gives you DRASTICALLY better color and detail.

Is there such a thing as 480i? Yes. HDTVs have to handle that also.

480i isn't progressive scan, it's the interlaced version of the low-end of HDTV.

HDTV formats are:

480i

480p

720p

1080i

The PS2 and GC support 480i.

Most recent GC games support 480p.

Very few PS2 games support 480p.

The Xbox supports ALL formats. Whether the games take advantage of it is a different story.

For a list of ALL games and what they support, click here:

Here's a good link showing the differences between them:

thanks starman. And what do you hold to set up progressive on xbox?

You need to use the Xbox HDTV pack ($20 with component outputs), and once that's plugged in, the options for turning on different HDTV modes will become available in the dashboard.
