4K's TV Adventure
The successor to HD, 4K (Ultra HD) will only become widespread with a drop in price, sensible business models and the proliferation of 4K content and services. 2014 was supposed to be the year for 4K, but without a convincing argument for the standard – and the means by which to easily access it – it didn't really happen. 4K is now 2015's to foster and the options are it either falling away or being turned into an attractive proposition. The latter is far more likely.
4K resolution, also called 4K, refers to a display device or content having horizontal resolution on the order of 4,000 pixels.Several 4K resolutions exist in the fields of digital television and digital cinematography. In the movie projection industry, Digital Cinema Initiatives (DCI) is the dominant 4K standard.
The DCI 4K resolution standard is defined as 4096 x 2160 pixels (256:135, approximately a 1.9:1 aspect ratio). This standard is widely respected by the film industry along with all other DCI standards.
DCI 4K should not be confused with ultra-high-definition television (UHDTV) AKA "UHD-1", which has a resolution of 3840 x 2160 (16:9, or approximately a 1.78:1 aspect ratio). Many manufacturers may advertise their products as UHD 4K, or simply 4K, when the term 4K is traditionally reserved for the cinematic, DCI resolution.This often causes great confusion among consumers.
The use of width to characterize the overall resolution marks a switch from the previous generation, high definition television, which categorized media according to the vertical dimension instead, such as 720p or 1080p. Under the previous convention, a 4K UHDTV would be equivalent to2160p.
