The consumer Electronics Association or CEA has announced that 4K is now Ultra High-Definition. But the question on most peoples minds is - what the Ultra High-Definition change means to home theaters? (Image credit: Flickr) 
Other than the fact that 4K will officially be known as Ultra High-Definition, or Ultra HD for short, there are marketing implications for TV manufacturers. UHDTV was already an International standard, fact in August, the International Telecommunication Union approved the use of the name Ultra High Definition for both 4K (3840 x 2160) and 8K (7680 x 4320) resolutions. What the Ultra High-Definition change means to home theaters is that companies can only use the Ultra HD label when their products have at least one input capable of transmitting native 4K video at 3840 x 2160 resolution without upconverting. Another implication is that Screens will have to have eight million active pixels, with at least 3,840 horizontal pixels and 2,160 vertical pixels at minimum. If the CEA's announcement was meant to prevent any confusion Sony is not actually helping. the company while lauding the CEA says it will continue to use 4K for its current products and will label future products as 4K Ultra High Definition (4K UHD). Here is their statement -
While pixel enthusiasts are probably rejoicing with the implications of what the Ultra High-Definition change means to home theaters. Some if not most will hold out on an upgrade for the NHK 8K Super Hi-Vision. So what the Ultra High-Definition change means to home theaters is really just an enormous amount of detail in your viewing. Let us know your thoughts on what the Ultra High-Definition change means to home theaters and the Sony announcement.

Here is their statement -Just a quick note to let you know that as a leader at the forefront of new display technology such as HD, 3D and beyond, Sony lauds the CEA’s efforts to come up with a common language to describe the next generation high-definition technology. However, to ensure clarity for consumers and delineate between today’s and tomorrow’s technology, Sony will continue to use the 4K moniker for its products and will market its future products as 4K ultra high-definition (4K UHD).
