4k, UHD, HDR10 , Dolby Vision: When buying a TV, it is no longer just about size, but about resolution and brightness. The new formats can be confusing.

Ces 2018: Who has the brightest?

The Consumer Electronics Show (CES) InLas Vegas has seen so many format wars. At end of 1970s, VHS and Betamax video cassette formats DerKunden favor. It took years to get VHS Videokassettegegen developed by JVC more technically sophisticated Betamax standard from Sony Durchgesetzthatte.

The era of high-resolution television also began with a dispute over Dasrichtige technical format. At that time, rival standards of Blu-Rayund HD DVD competed against each or when it came to finding a successor format for Dieherkömmliche DVD. Behind Blu-ray were companies like Panasonic, Sonyoder Philips, while HD DVD was supported by significantly smaller competitors like Toshibaoder NEC. The big players went through it, Konntenauch influential companies like Microsoft and Intel did not change anything that Sichzuletzt had made strong for HD DVD yet.

The HDR format war

At current CES it is mainly about question, wieHelligkeitskontraste and gradients are displayed on TV. In meantime, devices with a high 4k resolution (UHD) are now quasi standard, even if first TVs with 8k have already been introduced. However, re are significant differences in both image quality among 4k devices. Television with HDR (High dynamic Range) promise to portray images in terms of brightness and contrast in such a way that y hardly differ from DerRealität.

A conventional TV without HDR controls 256 brightness levels (eight bits). On or hand, an HDR standard TV can display 1,024 brightness levels (ten-bit). Especially films with sequences that are very bright odersehr dark (for example, pictures in snow or in a cave) benefit from this. The company Dolby Laboratories, which was mainly Tonoptimierungbekannt with systems, went one step furr and developed a system with twelve bits (4,096 brightness levels) and a dynamic adaptation depending on film sequence. In case of Dolby Vision baptized technology, Farbanpassungnicht is defined once for entire film, but for each image einzelnübertragen. The conventional HDR, on or hand, is static and does not adapt to individual scenes.

In fact, re is nothing to stand in way of a success of Dolby Vision, but re is a problem: Dolby wants to use procedure money Verdienenund requires royalties from film studios and manufacturers of TV sets. Companies like Samsung don't want to Accept. Against this backdrop, South Koreans developed HDR10 as an open standard, which also allows einedynamische adjustment and where no royalties are due.

Which provider supports which format?

The main focus now is on content providers. The TV providers in Germany – from public service to most PrivatenSendern – do not play any role in this, because y do not even send in 4k, except for a few Ausnahmennoch. 4k content distribution channels include Blu-ray, TV boxes such as Apple TV 4k, Amazons Fire TV, decoder from sky, or even current game consoles. The three GroßenStudios Sony, Paramount and Universal Dolby Vision are supported by film studios. 20th Century Fox Dagegenpositioniert is a supporter of HDR10 , while Warner also offers title of Indolby vision. The Disney group, which wants to buy 20th Century Fox, currently supports only Dolby Vision and somewhat older HDR10.

The formative policy of streaming could be decisive. Since EndeDezember you can play HDR10 videos on Amazon Video on Aktuellen4K TVs from Samsung in Germany. Netflix offers as well as ITunesseinen customers both movies in HDR10 as well as in Dolby Vision. At HDR10 , Netflix first gets off, as product manager Greg Peters said.

Panasonic is taking on an intermediary role in format dispute. At Derdiesjährigen ces Stelltendie, Japanese has a player for ultra-HD-Blu-rays that supports two KonkurrierendenHDR formats. However, or manufacturers have not yet moved on, so that in coming years re is a showdown in living rooms kommenkönnte.

At same time, it is also case that, Währenddie discussion about format subtleties, many consumers have not even heard term HDR, says Samsung manager Kai Hillebrandt. As always on consumer Electronics Show, it is primarily about reengineering, which Perhaps only in a few years consumer really reached. For people who now want to buy a new TV, it is already relevant.
