So 4K is downsampled to 1080p through the wonder of osmosis, is it? No. Scaling images correctly has always been at the heart of transferring movies to digital video, but, as the veteran visual effects producer Mr.D has said on here many times, some studios have simply cropped their 2K DI's for HD rather than scale them down because of the loss in quality that can result.
My point being that scaling is not an exact science; you only have to look at the aliasing on something like MGM's brand new Great Escape Blu-ray to know that this issue is an ongoing concern, so surely it's a good thing that Sony are providing the exact same scaling engine that they used to downsample their movies to their 4KTV customers? It will make for the most transparent possible method of upscaling these faux-K Blu-rays to 4K, even if there is only a tiny improvement (if any, like I said above, because no-one yet knows if it'll make any appreciable difference).
Is it the greatest thing ever? Of course it bloody well isn't. Is it mostly marketing hoopla? You betcha, because it's proprietary to Sony which means that everyone's else's Blu-rays that've been mastered from 4K are **** out of luck (not to mention Sony's own pre-existing Blu-rays mastered from 4K sources which don't carry the metadata needed to trigger the specific scaler!). And, as and when 4K software finally comes to market, this feature will become a mere footnote - BUT until it's proved to be 100% pure pixie dust I will continue to be intrigued by the possibilities.
