Viewing HDR Contents
When viewing HDR contents, making adjustments according to the content and viewing environment allows the images
to be played back in higher quality.
What is HDR content?
HDR (High Dynamic Range) refers to images with a significant difference in brightness between the highlight and
shadow areas (dynamic range). It is a technology that enables faithful and realistic reproduction of the original colors
as well as glitter and details of shadows that could not be expressed by the conventional SDR (Standard Dynamic
Range). The international standard for HDR is set forth in the ITU-R (International Telecommunication Union –
Radiocommunication
Sector) BT.2100. Enhancements have been made in many aspects compared to ITU-R BT.709,
which was the conventional Full HD standard.
HDR can largely be divided into two different formats, namely HDR10 which is employed by UHD-BD and video
streaming services, and Hybrid Log-Gamma which is employed for broadcasting. Compared to the conventional SDR,
the standard HDR format HDR10 delivers a higher resolution, higher luminance and higher gradation as well as a wider
color gamut to reproduce images more realistically in combination with the wide dynamic range.
