The Panasonic DMP-UB900 is Panasonic’s first Ultra HD (4K) Blu-ray player. The price is presumed to be around $499 but has not been confirmed yet. The specifications indicate this is meant to be a higher end play with lots of features and thoughtful abilities (like up-scaling of 4:2:0 color to 4:4:4).
The Blu-ray Disc Association has finalized the specification for Ultra HD Blu-ray which supports up to a 3840×2160 resolution and extended dynamic range (HDR), amongst other things.
Disc based media has been predicted to by dying off, but this move certainly will prolong the life span. Digital Rights Management has yet to be clarified. These discs are to have capacities of 66 or 100GB.
