While the BDA has NOT yet finalized the specifications for 4K BD discs and players, there are some things that I am pretty excited about that seem to be on the plate regardless if the t's are cross or the i's are dotted. The features I am referring to will require hardware to support, but these features, IMO, are more important and desirable than the 4K resolution. I wrote about this back on 11/4/13, but now it seems more of a reality! For starters: Color sub-sampling of 4:4:4 vs. Blu-Ray's color sub-sampling of 4:2:0. What does this mean? More accurate color as color information per pixel is not thrown away. 10-bit gradation vs Blu-Ray's 8-bit gradation. What does that do for you? Well the best example is watch any BD movie where a person is underwater looking up at the sun. You will see banding around the sun in the blue water. This artifact essentially disapears with 10-bit gradation. HDR (High Dynamic Range). This is kind of an open standard that allows for substantial increase in dynamic range for peak brightness. One of the technologies that supposedly will be supported is Dolby Vision. Read my write up on that here. If it is good as what I saw at Dolby -- this will be impressive. and last but not least an increased color gamut. BD 4K will support the REC2020 color gamut from the previous 1080P standard REC709. Forget the 4K, just get me the above ASAP. Of course, I will have to buy all new equipment... I've been waiting eagerly for this day... This holiday there will be some nice XMas presents in my HT! Who else is going to be replacing all their stuff?!
