Samsung och LG i öppet bråk om 8K

De två koreanska elektronikjättarna LG och Samsung bråkar just nu intensivt med varandra när det handlar om tv-apparater med 8K-upplösning. Det rapporterar affärspublikationen Korea Times. Bråket tog sin början under IFA-mässan i Berlin, då LG avfärdade Samsungs tv-apparater för att de inte möter de krav som satts upp av kommittén International Committee for Display Metrology, något som man dessutom valde att bjuda in reportrar till en diskussion om.

Samsung har sedan dess försvarat sig i samband med en tv-konferens, där man bland annat påpekade att man måste ta hänsyn till fler faktorer än dem som LG nämnt i sin kritik. Efter det har dessutom medlemmarna i organisationen 8K Association kommit överens om en global standard för tv-apparater med 8K. 16 företag (inte minst ett antal stora tv-tillverkare) ingår i organisationen, men LG är inte ett av dem.

Bråket har i huvudsak handlat om antal pixlar och kontrastvärden.

Samsung är världens största tillverkare av tv-apparater, tätt följda av LG på andra plats.

 
8K
Wikipedia (en)
8K resolution refers to an image or display resolution with a width of approximately 8000 pixels. 8K UHD (7680 × 4320) is the highest resolution defined in the Rec. 2020 (UHDTV) standard.8K displays are said to produce images with such detailed colors that they evoke stronger sensory experiences. This phenomenon has been likened to hyperrealistic art. High-resolution displays such as 8K allow for each pixel to be indistinguishable to the human eye when viewed at a typical distance from the screen. 8K resolution can also be used for the purpose of creating enhanced lower resolution videos through a combination of cropping techniques and/or with downsampling techniques used in video and film editing. Resolutions such as 8K allows filmmakers to shoot in a high resolution with a wide lens or at a further distance, in the case of potentially dangerous subjects (such as in wildlife documentaries), by being able to zoom and crop digitally in post-production. The technique involves taking a portion of the original 8K image and cropping it to match a smaller resolution such as the current industry standard for high-definition televisions (4K, 1080p, and 720p).8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources. It is predicted that 8K-ready devices will still only account for 3% of UHD TVs by 2023 with global sales of 11 million units a year. However, TV manufacturers remain optimistic as the 4K market grew much faster than expected, with actual sales exceeding projections nearly 6-fold in 2016.In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high data rates. The demand is expected to drive the adoption of video compression standards and to place significant pressure on physical communication networks in the near future.As of 2018, few cameras had the capability to shoot video in 8K, with NHK being one of the only companies to have created a small broadcasting camera with an 8K image sensor. By 2018 Red Digital Cinema camera company had delivered three 8K cameras in both a Full Frame sensor and Super 35 sensor. Until major content sources are available, 8K is speculated to become a mainstream consumer display resolution around 2023 as mentioned in UHD forum Phase-B recommendations. Despite this, filmmakers are pushing demand for 8K cameras due to their ability to capture better 4K footage.
