ITU-R BT 2020 ” Parameter values for ultra-high definition television systems for production and international programme exchange

BT 2020 defines the parameters of UHDTV (Ultra High Definition Television), including display resolution, frame rate, chroma sub-sampling, bit depth, color space and audio system. Standard colour Gamut and wide colour gamut, which uses different red, green and blue primaries are included for. The image sizes are 4K (3840 x 2160) and 8K (7680 x 4320), with frame rates 23.976, 24, 25, 29.97, 30, 50, 59.94, 60 and 120 Hz. All scans are progressive. The system offers a wider dynamic range with the images’ colorimetry including a wider gamut than HDTV, which is already wider than SD. Sampling may be 10 or 12-bit and 4:4:4, 4:2:2 or 4:2:0 to suit the application.
