Will upconverting DVD player make a significant difference over a progressive scan DVD player?

Question

When playing a DVD on a 1080i HDTV. Thank you!

Some more clarification: By upconverting DVD, I am referring to DVD players that upconvert the DVD signal to 1080i before transferring to the TV. Sincem y TV's native mode is 1080i, I am assuming that the TV does some upconverting as well. Now the question is whether the DVD upconversion will be much better than TV upconverting?

Derajer, I havea Toshiba DLP TV. the native resolution must be 720p because it is not 1080p! If the multiple conversions do not lose much quality, just add a delay, then I am fine because I do not notice any sync issue with the audio. If te conversions cause quality loss, then I should invest in a upconverting HDMI chip DVD player (one that converts the video to 720p...). Thanks!

Answer 1

Since HDMI leaves the signal in the digital realm, there will be some improvement over component. As another answer stated results will vary on the quality of the up converter and the quality of the disc. Worse case scenario is that the upscaling HDMI video will actually show the limitations of a poor DVD...

An HDMI DVD player still uses progressive scan, it just delivers a digital signal to the TV.

Answer 2

Essentially all that an HD upconverting DVD player does to improve things is eliminate multiple conversions. here's what happens in P-scan
1. Generate digital 480p image from disc
2. convert to analog stream for component video and send
3. receive at tv and convert back to digital (assuming digital tv)
4. convert to native resolution of tv (720p for example)

All of these are skipped when you use an hdmi dvd player, this is where they benefit. Make sure you buy one with a good upconvert chip like farouja, personally I own an LG. I would also question your 1080i native resolution. This is very unusual, if it is a CRT or CRT projection then it doesn't have a native resolution. If it is a LCD, DLP, SXRD, HDILA, or PLASMA it will have a 720p or 1080p native resolution. It is important that you know for sure exactly what your native resolution is so that you can match it to the output of the DVD player for minimal conversions.

Answer 3

Your results will vary. Many factors are involved: the quality of the DVD player and the quality of the image on the DVD. Apparently high-end, very expensive DVD players can make an improvement in image quality over standard component interface. But unless the image on the DVD is the very best, that won't necessarily be noticeable. Lower-priced DVD players can also offer some improvement; HDMI interface and upscaling offer opportunities for image enhancement and reduced image deterioration, if the player is well-designed. Check for reviews on CNET and in good A/V magazines (Widescreen Review, The Perfect Vision) to get the facts.

Answer 4

well as they change all the time progressive scan is Reilly nice and some day it will be replaced with some thing new but for now it is not going to be anything new when it comes to progressive scan and there will be new model's when i all comes down to it all you will get the same and here is something to know that if you don't got a hd TV you will not get the pitcher quality you have to have hd with progressive scan DVD
