    I have bought a Samsung 850 DVD player for my Sammy 32" LCD, and I have read lots about how the upscalling will delivery an imporved picture.

    Could anyone point me in the direction of an article or thread which describes exactly how this process works?

    Cheers

    Well, the "proof of the pudding is in the eating" so they say so it is perhaps best to remain blissfully ignorant of the gory detail (like me) and simply feast on the results.

    However, there is a common misconception that upscaling in the DVD player will automatically give a better picture. It may do, but it's not guaranteed. It all depends whether the scaler in the player is better than the scaler in the display. If you've spent a few K on a display device, and a hundred quid on a DVD player, it kinda suggests the scaler in the display may be better.

    But what I really want to know, is whats going on when the player upscales? What is it doing...someone must know.

    Upscaling is where they take pixels and work out the relative difference between them in terms of colour and brightness (interpolation) then stick in a fake pixel in between them. So you could say it's a fudge, but it does give the impression of a higher resolution picture than what you started with. Though a high res picture in the first place is of course more accurate. You can't get something from nothing, you can only guess.

    Regards

    There'a a specific forum "video scalers, video processing and progressive scan" - that may be a better bet for this question...PJ :)
