Progessive Scan Benefits??
 

Well I've just got a standard dvd player with progessive scan. I was wondering if I should keep that on all the time? What's the significance of it? The other day i hit it by accident and totally forgot i had the option. Can't really say i see a difference. Just thought i'd keep some feedback. Thanks

is it connected via component cables?

Advantages of progressive scan

* Easier video authoring
* Subjectively higher vertical resolution than interlaced video with the same line rate

The perceived vertical resolution of an interlaced image is usually equivalent to multiplying the active lines by about 0.6. This means that, when viewing progressive sourced material, a progressive display will show a more detailed image, when compared to an interlaced one, even if both have exactly the same display resolution, such as 640 x 480 pixels.

* Eliminates visual artifacts associated with interlaced video of the same line rate, such as interline twitter
* Intentional blurring (sometimes referred to as anti-aliasing) of video to reduce interline twitter and eye strain on interlaced displays is not necessary when using progressive scan. Foregoing this blurring process further improves clarity of the progressive image.

In the case of most media such as DVD movies and video games, the video is blurred during the authoring process itself to mask flicker artifacts when used on interlace displays. As a consequence, recovering the sharpness of the original video is impossible when the video is viewed progressively. An excellent, but rarely employed countermeasure to this is when display hardware and video games come equipped with options to blur the video at will, or to keep it at its original sharpness. This allows the viewer to achieve the desired image sharpness with both interlaced and progressive displays. An example of a video game with such a feature is Super Smash Bros. Melee, where a "Deflicker" option existed. Ideally it would be turned on when played on an interlaced display to reduce interline twitter, and off when played on a progressive display for maximum image clarity.

* Offers much better results for upconversion on higher resolution displays than equivalent interlaced video, such as upconverting 480p to display on a 1080p HDTV. The deinterlacing process is skipped, which results in faster video processing from source to display, which is quite important for playing time-sensitive video games. It also eliminates the prospect of poor deinterlacing jobs, which can actually make the resulting video look worse than its interlaced equivalent.

Whether you can use progressive scan or not depends on whether your TV can display it.

Very true. You need to have an hdtv, or an edtv to get the benefits. It must also be hooked up through component,dvi, or hdmi.

Ah well i don't have an hd so i guess i'm out of the lineup. Thanks for the info though everyone!
