Question

What is the purpose of " Upconvert DVD "?

Answer 1

DVD players that have the ability to improve the image quality of the movies being played are commonly called "upconverting" DVD players. The correct term for the process is called scaling. The DVD player has a chip that applies advanced techniques to fill in the spaces between the lines on the DVD (which is recorded at 480 lines) to bring the "pseudo" resolution to ,typically, 720 lines progressive, 1080 lines interlaced or 1080 lines progressive. The better quality the chip, the better the scaling looks. Because of DVD copyright regulations, the DVD player must be connected with an HDMI (or DVI on a few older models) cable for the scaling to work.

While the term upconversion is commonly used, it really refers to a devices ability to intake one type of video signal and output a better type of signal. For example many newer receivers can take in an S-Video or component video cable and output the image through an HDMI cable. While that doesn't mean it improves the image in and of itself, many of the "upconverting" DVD players also have scalers built in as well to improve the picture.

Hope this helps

Answer 2

an up converting DVD player brings the quality of a regular DVD to "near" HD quality.

Answer 3

DVD Upconverting, also known as Upscaling:

[edit] Upscaling DVD

Upscaling DVD (Digital Versatile Disc) Players are a reasonably cheap way of upscaling standard DVD-Video discs using a video scaler to match the pixel count of the signal to the physical, or native, pixel count on a high-definition television or computer monitor, resulting in better detail and color consistency. Standalone DVD players which feature upscaling use either a standard component video or VGA analog cable, or a DVI-D or HDMI digital cable to connect to the high-definition television. Standalone DVD players with component video or VGA output connectors use a digital-to-analog integrated circuit microchip which does the upscaling, while DVD players with DVI-D or HDMI output connectors use a digital-to-digital integrated circuit microchip which does the upscaling. Computer software DVD-Video players like PowerDVD and WinDVD also features upscaling of DVD-Video.

Answer 4

To sell more dvd players. They charge more than ones that don't convert. And it appears to some to be a middle ground without having to pay a ridiculous amount for high def DVD formats.

In brief, both HDTVs and upconverting DVD players will deinterlace/rescale a DVD disk to HD resolution (as high as 1080p), but a good upscaling player will do a better job than most HDTV. The result is a picture of close to HD quality.

They certainly works ... despite the naysayers who will thumbs down this answer ... but only on a player with better video processing (e.g. Oppo). Cheap upconverters (under at least $100) are a waste of money.
