Macroblocking question

[savechief]

So upconverting DVD players, especially those with the Faroudja chip, have macroblocking issues. So let's say that you have an ED plasma and a DVD player that DOESN'T upconvert over component video. So then let's say that you hook up the upconverting DVD player (that has, let's say, a Faroudja chip in this example) to the ED plasma over component.

Would macroblocking be possible in this situation?

The problem is caused by using the FLI23xx chips. If you output an 576i/480i interlaced signal and don't use True Life, then there is no problem.

Theoretically you could have a 480i output on HDMI without the problem, but I have yet to see this in practice.

savechief, MB has nothing to do with upconverting or DVI/HDMI connection. It has everything to do with the Faroudja chip when matched with certain displays. Case in point: the Yamaha S1500 does not have DVI or HDMI output, does not upconvert, but does have MB thanks to the Faroudja chip. So even 480p over component can have MB.

What is Macroblocking? Can you gimme explanation thanx..

Actually, I thought that it had everything to do with upconverting and DVI/HDMI connection. Let's take the Oppo player, for instance. It only upconverts over DVI/HDMI. And my impression was that the player only utilized the Faroudja chip when it upconverted. So, if you were to use the component output, you would get 480i out of the machine and the Faroudja chip would not be used. Am I mistaken?

The Oppo is not a great example because it does not output 480p over component. You are probably correct, then, in that if you output 480i over component, the Faroudja chip is not utilized. Of course, that would defeat what's great about the Oppo - the Faroudja deinterlacing chip. For every other progressive scan player that has the Faroudja chip, the Faroudja chip is used for deinterlacing. Thus, if you output 480p over component or DVI or HDMI with the Yamaha S1500, Denon 1910/2920/3910, Zenith 318, Samsung 941, etc, etc, you can still have MB, depending on the display. Thus, for most Faroudja players, it has nothing to do with upscaling or DVI/HDMI since the chip is utilized for deinterlacing, not just upscaling.
