On September 15, 2012, David Wood, Deputy Director of the EBU Technology and Development Department (who chairs the ITU working group that created Rec.

2020), told The Hollywood Reporter that Korea plans to begin test broadcasts of 4K UHDTV next year.

Compared to the audio domain, it is essentially noise shaping.

In the case of images and video, the "noise" will be shifted into frequencies beyond what the eyes are able to resolve, cleaning up the usably bandwidth which is the actual image the user is supposed to see. 2020, higher dynamic range, and higher frame rates to work on HD services without increasing resolution to 4K, providing improved quality without as high of an increase in bandwidth demand.

The Ultra HD label also requires the display to have an aspect ratio of 16:9 or wider and to have at least one digital input that can carry and present a native video signal of 3840x2160 without having to rely on a video scaler.

The preloaded 4K movies are The Amazing Spider-Man, Total Recall (2012), The Karate Kid (2010), Salt, Battle: Los Angeles, The Other Guys, Bad Teacher, That's My Boy, Taxi Driver, and The Bridge on the River Kwai.

UHDTV, however, allows other image enhancements than pixel density. 2020 color space covers 75.8%, compared to coverage by the DCI-P3 digital cinema reference projector color space of just 53.6%, 52.1% by Adobe RGB color space, while the Rec. On December 31, 2006, NHK demonstrated a live relay of their annual Kōhaku Uta Gassen over IP from Tokyo to a 450 in (11.4 m) screen in Osaka.

Specifically, dynamic range and color are greatly enhanced, and these impact saturation and contrast differences that are readily resolved and greatly improve the experience of 4KTV compared to HDTV. 2020 (UHDTV) color space which can reproduce colors that cannot be shown with the current Rec. Using a codec developed by NHK, the video was compressed from 24 Gbit/s to 180–600 Mbit/s and the audio was compressed from 28 Mbit/s to 7–28 Mbit/s.On January 14, 2013, Blu-ray Disc Association president Andy Parsons stated that a task force created three months ago is studying an extension to the Blu-ray Disc specification that would add support for 4K Ultra HD video.On January 25, 2013, the BBC announced that the BBC Natural History Unit would produce Survival—the first wildlife TV series recorded in 4K resolution.The human visual system has a limited ability to discern improvements in resolution when picture elements are already small enough or distant enough from the viewer.At home-viewing distances and current TV sizes, HD resolution is near the limits of resolution for the eye and increasing resolution to 4K has little perceptual impact, as consumers are beyond the critical distance (Lechner distance) to appreciate the differences in pixel count between 4K and HD.This was announced after the BBC had experimented with 8k during the London Olympics.
