We all know that when viewed from an appropriate distance 4:2:0 encoding, when done properly on good source material, looks very good at 1080p. I know on my Sony 52" XBR4 good BD's look pretty amazing.
But I'm wondering what will happen when affordable high quality screens reach 80 or 100" or larger. Eventually the picture will start to break down.
It seems likely that 1080p will be with us for quite a while as manufacturers will most likely stay with a format that is currently supported by hardware and software.
So I'm wondering if eventually we might see a 4:2:2 or 4:4:4 consumer delivery format to eek that last bit of performance from the 1080p standard. Of course current viewing devices could handle it. Computer playback wouldn't be a problem. I don't know how difficult it would be to adapt BD discs and players to such a format but it seems as though it might be accomplished relatively cost effectively.
I know that the human eye can see some of the detail between 4:2:0 and the other color spaces I mentioned but when you start to magnify pixels there definitely is a visible difference.
And it seems like there is plenty of space available on most BD's since a dual layer disc can hold 50GB and most movies are only about 30GB or so. I personally could do without most of the extra garbage for a version encoded using a better colorspace.
Just a thought.
